ABSTRACT
Theranostics in nuclear medicine is an important direction for the precision medicine. Radionuclide therapy based on small molecules/peptides often requires high doses. Improving the utilization efficiency of radionuclides, optimizing the pharmacokinetics of radionuclide therapeutic molecular probes as well as increasing the target to non-target ratio have become the international hot frontiers in the field of radiotheranostics. Evans blue (EB) motif uses endogenous albumin as a reversible carrier, and the small molecule and polypeptide structure modified based on EB can effectively extend the half-life in the blood and substantially increase the uptake, accumulation and retention of radiopharmaceuticals in target lesions, and thereby enhance the therapeutic effect and reduce the dosage of nuclides. This article focuses on the research of EB modified radiopharmaceuticals for theranostics.
ABSTRACT
ObjectiveTo evaluate the value of MicroPure software system in the display of calcification and diagnostic accuracy of breast carcinoma.MethodsSixty-three patients with 68 breast lesions were checked by conventional ultrasound,X-ray and MicroPure software technique.The calcification was described and the lesions were classified with BI-RADS.All cases were pathologically confirmed by biopsy or operation.Results ①Compared to the detection rate for calcification of X-ray,the display rate of conventional ultrasound was 80.6% ,and the display rate of MicroPure software technique was 100%.②The area under the curve of diagnosing benign and malignant of breast lesions was 0.916,0.857 and 0.970 respectively with ultrasound,X-ray and MicroPure software technique.③Three lesions was classified Ⅲ in BI-RADS with conventional ultrasound,and Ⅳ in BI-RADS with MicroPure software.The pathologic results were malignant.ConclusionsMicroPure software system obviously raised the ultrasonic display rate of calcification,meanwhile,it raised the diagnostic accurate rate of breast cancer.It especially raised the tendency rate for the patients who were classified between Ⅲ and Ⅳ in BI-RADS.
