MRI动态增强技术对小乳腺癌的诊断价值
Preliminary application of dymaic-contrast MRI in diagnosis of small breast cancer
摘要
Abstract
Objective: To study the imaging features and time- signal intensity curve of small breast lesions, and to evaluate the value of clinical application of dynamic contrast-enhanced MRI scan technique in diagnosis of small breast cancers. Methods: Thirty nine female patients pathologically confirmed small breast lesions(≤2 cm)underwent bilateral breast dynamic contrast enhanced MRI. Use MRI workstation function software to describe the time- signal intensity curve(TIC). Results: 19 cases were pathologically confirmed as small breast cancer, 20 cases were benign breast tumor. 15 cases of small breast cancer showed TIC typeI, 3 cases showed type II, 1 cases showed type III.Eleven among 19 cases of early enhancement rate ≥60%. Two among 20 cases of benign tumor TIC curve showed type I, 2 cases showed type II , 16 cases showedtype III, 5 cases of benign tumor early enhancement rate≥60%. The morphological characteristics, early enhanced rate≥60%, TIC type I as the diagnostic criteria.The combination of two types of information in the presented diagnostic algorithm achieved an optimized sensitivity of 92%, specificity of 90%, accuracy of 95%. Conclusion:MRI features of breast lesions in combination with the TIC and the early phase enhancement rate improves breast small tumor diagnosis sensitivity and specificity, which can provide valuable information in diagnosis of small breast cancer.关键词
