【摘要】：目的探討MRI動態(tài)增強掃描(dynamic contrast-enhancement magnetic resonance imaging,DCE-MRI)與乳腺X線攝影在乳腺病變診斷中的應用效果。方法對在我院收治的乳腺病變患者應用DCE-MRI與乳腺X線攝影進行檢查,并就這兩種檢查方法在發(fā)現(xiàn)病變及良惡性腫塊鑒別方面的診斷能力進行對比研究,以期客觀評價兩種檢查方法對乳腺疾病的診斷效能。結(jié)果以病理確診結(jié)果為金標準,計算乳腺X線攝影診斷良、惡性乳腺病變的敏感性為65.63%,特異性為70.37%,準確性為68.60%;DCE-MRI診斷良、惡性乳腺病變的敏感性為87.50%,特異性為90.74%,準確性為89.53%;經(jīng)統(tǒng)計學分析發(fā)現(xiàn)DCE-MRI診斷良、惡性乳腺病變的敏感性、特異性及準確性均明顯高于乳腺X線攝影,且差異具有統(tǒng)計學意義。結(jié)論乳腺X線攝影和動態(tài)增強MRI對乳腺病變的鑒別診斷均有一定的實用價值,但是乳腺動態(tài)增強成像能夠提供更加豐富的形態(tài)學信息,診斷效能優(yōu)于乳腺X線攝影,兩者的結(jié)合可以發(fā)揮優(yōu)勢互補的作用。
[Abstract]:Objective to evaluate the effect of MRI dynamic enhanced scanning (DCE-MRI) and mammography in the diagnosis of breast lesions. Methods DCE-MRI and mammography were performed in patients with breast lesions in our hospital, and the diagnostic ability of the two methods in the differential diagnosis of benign and malignant masses was compared. Objective to evaluate the effectiveness of the two methods in the diagnosis of breast diseases. Results according to the gold standard of pathological diagnosis, the sensitivity, specificity and accuracy of DCE-MRI were 65.63, 70.37 and 68.60m respectively. The sensitivity, specificity and accuracy of DCE-MRI in the diagnosis of benign and malignant breast lesions were 87.50%, 90.74 and 89.53, respectively. The sensitivity, specificity and accuracy of DCE-MRI in the diagnosis of benign and malignant breast lesions were significantly higher than those in mammography, and the difference was statistically significant. Conclusion both mammography and dynamic contrast enhanced MRI have some practical value in the differential diagnosis of breast lesions, but dynamic enhanced mammography can provide more abundant morphological information, and the diagnostic efficacy is better than that of mammography. The combination of the two can play a complementary role.
