Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The medicine injection dose detection method provided by the application can be applied to a medical scanning imaging method needing medicine injection, and the medical scanning imaging can be specifically single-mode scanning imaging, such as PET imaging and the like; the medical scanning imaging may also be multi-modality scanning imaging, such as PET-CT (positron emission tomography-electron computed tomography) imaging, PET-MR (positron emission tomography-magnetic resonance scanning) imaging, and the like, and is not particularly limited herein.
in one embodiment, as shown in fig. 1, there is provided a method for detecting an injected dose of a medicine, which is explained by taking as an example that the method is applied to a processor that can control detection of an injected dose of a medicine, the method including the steps of:
Step S100, before medical imaging scanning is carried out on the target object, a predicted injection dosage of the medicine corresponding to the target object is obtained.
Taking PET scanning as an example, according to the scanning principle, before PET scanning is performed on a target object, drug injection is required, and the injected drug can play a role of a developer, mainly to make imaging clearer. The main material used at present is Fluorodeoxyglucose (FDG), also known as 18F-FDG, whose complete chemical name is 2-fluoro-2-deoxy-D-glucose, and after the target object is injected with the drug, 18F-FDG enters cells through cell membranes with the help of glucose transporters and is further converted into 6-P04-18F-FDG, and if there are tumors in human body, the tumor cells will adsorb 18F-FDG in large quantity, because the uptake of 18F-FDG by cells is proportional to the glucose metabolism rate, and the higher the glucose metabolism rate, the more aggregated 18F-FDG is taken up by cells. That is, because the metabolic capacity of the tumor cells is relatively vigorous, the uptake of 18F-FDG by the tumor cells is far higher than that of normal cells, namely, the 18F-FDG in the tumor cells is more accumulated, and the characteristics can be reflected by scanning images, so that the PET scanning injected with 18-FDG can be used for early discovering the primary and metastatic focuses of the whole tumor, accurately judging the benign and malignant tumors, and correctly guiding the clinical treatment decision.
in this step, before injecting the drug into the target object, the processor first obtains a preset injection dose of the drug corresponding to the target object, where the preset injection dose of the drug is a dose of the drug that needs to be used in the PET scanning process determined by a doctor or a medical worker according to the physical health condition of the target object, and the mode of determining the preset injection dose of the drug can be implemented by a determination method in the prior art.
Alternatively, the processor may obtain the preset injection dosage of the drug by obtaining the preset dosage input by the doctor or the medical staff through the human-computer interaction device, for example, the processor is in communication with the parameter setting structure, and the doctor or the medical staff inputs the preset dosage through the setting panel of the parameter setting structure, so that the processor may obtain the corresponding preset injection dosage of the drug.
And step S200, obtaining a corresponding theoretical value of the activity of the medicine according to the predicted injection dose of the medicine.
The theoretical value of the activity of the drug refers to the value of the activity of the drug corresponding to the expected injection dose of the drug under ideal conditions. After cellular uptake, 18-FDG undergoes phosphorylation by hexokinase and is retained by metabolically active tissues (e.g., tumors), and the activity of the drug generally corresponds to the dose of the drug. In the PET scanning process, since the drug activity is a crucial parameter, which directly affects the imaging quality of PET, in order to determine whether the drug dose actually injected by the target object is the preset dose, the processor obtains a corresponding theoretical value of the drug activity according to the obtained predicted injected dose of the drug after obtaining the predicted injected dose of the drug, thereby facilitating subsequent determination.
Step S300, after the target object is injected with the medicine, acquiring an actual medicine activity detection value of the target object obtained through pre-collection.
The pre-acquisition refers to a processing mode of performing rapid whole body or half body scanning on the target object, for example, performing rapid low-dose scanning on the target object. After a doctor or a medical staff injects a medicine into a target object, because there is an unexpected circumstance that the actually injected medicine dose is not equal to a theoretical value, for the sake of insurance, in this embodiment, a PET scan is not directly performed on the target object, but a pre-scan is first performed, so as to obtain an actual medicine activity detection value of the target object.
Step S400, when the actual drug activity detection value is not matched with the drug activity theoretical value, the actual drug injection dose of the target object is confirmed to be not matched with the predicted drug injection dose.
After the processor obtains the theoretical value of the drug activity corresponding to the expected injection dose of the drug and the actual drug activity detection value of the target object, the processor can match the actual drug activity detection value with the theoretical value of the drug activity to determine whether the two values are consistent in order to detect and judge the actual injection dose of the target drug.
Specifically, when the actual drug activity detection value does not match the theoretical drug activity value, it may be considered that the drug activity corresponding to the actual drug injection dose in the target object does not match the drug activity corresponding to the predicted drug injection dose input by the doctor or the medical care personnel, and at this time, it may be confirmed that the actual drug injection dose of the target object does not match the predicted drug injection dose, that is, it indicates that an unexpected situation that the actual injected drug dose is not equal to the theoretical value occurs, and therefore, in the current situation, the problem that the scanning result may be inaccurate when the PET scanning is continuously performed on the target object may exist, and other processing measures need to be taken.
It is to be understood that the terms "consistent" and "matching" used in the embodiments of the present application may be understood as "consistent" and "matching" when the two are completely equal, for example, when m is equal to n, m and n are "consistent" and "matching", where m may be used to represent an actual drug activity detection value and n may be used to represent a theoretical drug activity value. In addition, it can also be understood that when the error between the two is within a preset range, the two are considered to be "consistent" and "matched", for example, when | m-n ≦ Δ, m and n are considered to be "consistent" and "matched", where m can be used to represent the actual drug activity detection value, n can be used to represent the drug activity theoretical value, and Δ can be used to represent the activity error threshold.
the embodiment provides a method for detecting the injection dose of a medicine, when medical imaging scanning requiring medicine injection is performed, after the predicted injection dose of the medicine is obtained, the medical imaging scanning is not directly performed, whether the actual injection dose of the medicine is matched with the predicted injection dose of the medicine is determined through pre-acquisition, so that a doctor can timely know whether an error exists in the actual injection dose, and can determine whether to continue the medical imaging scanning or perform the medicine injection again according to a matching result, so that the accuracy of the injection dose of the medicine injected into a human body can be ensured, and the accuracy of the scanning result is improved.
In one embodiment, the expected injected dose of the drug is used to obtain a corresponding theoretical value of drug activity, which includes: and obtaining a corresponding theoretical value of the medicament activity according to the predicted injection dose of the medicament and empirical factors corresponding to the medicament activity.
Specifically, the empirical factor is obtained according to the actual drug injection dose and the corresponding actual drug activity detection value, and the empirical factor represents the corresponding relationship between the drug injection dose and the drug activity. The processor may calculate an experience factor in advance through a large amount of actual data, for example, the network model may be trained through an actual drug injection dose and a corresponding actual drug activity detection value to obtain a trained neural network model, and parameters of the trained neural network model may include the experience factor, so that the trained neural network model may obtain a corresponding drug activity according to the drug injection dose. After the processor obtains the predicted injection dosage of the medicine, the processor can calculate and obtain a corresponding theoretical value of the activity of the medicine through a trained neural network model.
Alternatively, the empirical factor may be derived in other ways, such as from data such as relevant research results.
in one embodiment, as shown in fig. 2, after confirming that the actual injected dose of the drug of the target subject does not match the expected injected dose of the drug, the injected dose detection method of the drug further includes: and step S500, outputting prompt information that the actual injection dosage of the medicine is not matched with the predicted injection dosage of the medicine.
Specifically, after the processor obtains the predicted injection dose of the medicine input by the doctor or the medical staff through the human-computer interaction device, the processor firstly obtains a corresponding theoretical value of the activity of the medicine according to the predicted injection dose of the medicine, and after a doctor or medical staff injects the medicine to the target object, the actual medicine activity detection value of the target object obtained by pre-collection is obtained, then the actual drug activity detection value is compared and matched with the drug activity theoretical value, if the actual drug activity detection value is not matched with the drug activity theoretical value, the actual drug injection dose is not matched with the predicted drug injection dose, therefore, the processor outputs prompt information that the actual injection dosage of the medicine is not matched with the predicted injection dosage of the medicine through the display panel of the human-computer interaction device, thereby reminding the doctor or the medical staff of the current accident that the actual injected dose of the medicine of the target object is not matched with the predicted injected dose of the medicine.
Alternatively, in addition to outputting the prompt information through the display panel, the prompt may be made through other manners, for example, prompting through sound, light, or any combination of the above manners, and the like, and is not limited specifically herein.
in one embodiment, as shown in fig. 3, the method for detecting the injection dose of the medicine further includes: step S600, when the actual drug activity detection value is matched with the drug activity theoretical value, the actual drug injection dose of the target object is confirmed to be matched with the predicted drug injection dose.
specifically, after the processor obtains the predicted injection dose of the medicine input by the doctor or the medical staff through the human-computer interaction device, the processor firstly obtains a corresponding theoretical activity value of the medicine according to the predicted injection dose of the medicine, obtains an actual medicine activity detection value of the target object obtained through pre-collection after the doctor or the medical staff performs medicine injection on the target object, and then compares and matches the actual medicine activity detection value with the theoretical activity value of the medicine, if the actual medicine activity detection value is matched with the theoretical activity value of the medicine, the actual injection dose of the medicine can be determined to be matched with the predicted injection dose of the medicine, and PET scanning can be performed.
optionally, the processor may also output prompt information that the actual injection dosage of the drug matches the expected injection dosage of the drug through a display panel of the human-computer interaction device, so as to prompt a doctor or a medical care personnel that the current injection dosage of the drug is accurate and correct, and subsequent PET scanning operations may be performed.
in one embodiment, referring to fig. 3, after confirming that the actual injected dose of the drug of the target subject matches the expected injected dose of the drug, the injected dose detection method further includes: step S700, determining reference scanning time according to the actual drug activity detection value, wherein the reference scanning time is the time when the actual drug activity meets the medical imaging scanning requirement.
Specifically, determining a reference scan time from the actual drug activity detection value comprises: and determining the time when the drug activity is greater than the standard activity as the reference scanning time according to the actual drug activity detection value and the change relation between the drug activity and the time, wherein the standard activity is the drug activity meeting the medical imaging scanning requirement.
As shown in fig. 4, the change curve of the drug activity along with time is a change curve of the drug activity in the target object, which can be considered as a change curve that first rises and then falls, when the drug activity is greater than the standard activity, the PET scanning imaging quality corresponding to the change curve can be considered as better, so that the processor can obtain the actual drug activity change condition in the target user according to the actual drug activity detection value and the time information after the drug injection is performed on the target object, and thus, the time when the drug activity is greater than the standard activity is determined according to the actual drug activity change condition, that is, the reference scanning time.
Optionally, after the processor obtains the reference scanning time, the processor may output, through a display panel of the human-computer interaction device, prompt information of the reference scanning time corresponding to the target object currently undergoing the PET scanning, so that a doctor or a medical care worker may set the actual scanning time according to the reference scanning time, thereby improving the imaging quality of the PET scanning.
