【摘要】：目的:探討MR擴(kuò)散加權(quán)成像與不同成像序列聯(lián)合應(yīng)用對(duì)乳腺良惡性病變定性診斷價(jià)值。方法:回顧性分析71例(良性42例46個(gè)病灶,惡性29例32個(gè)病灶)經(jīng)手術(shù)及病理證實(shí)乳腺良惡性病變患者的MRI資料,以病理診斷為金標(biāo)準(zhǔn),統(tǒng)計(jì)并比較T_1WI結(jié)合DWI(T_1WI+DWI)、T_2WI結(jié)合DWI(T_2WI+DWI)、DCE、DCE結(jié)合DWI(DCE+DWI)這4種診斷方式對(duì)乳腺良惡性病變?cè)\斷的敏感性、特異性及準(zhǔn)確性。結(jié)果:T_1WI+DWI、T_2WI+DWI、DCE、DCE+DWI這4種診斷方式對(duì)乳腺良惡性病變?cè)\斷的敏感性分別為81.3%、90.6%、93.7%、96.8%,特異性分別為73.9%、91.3%、89.1%、93.5%,準(zhǔn)確性分別為76.9%、91%、91%、94.9%。結(jié)論:DCE聯(lián)合DWI對(duì)診斷乳腺良惡性病變有較高的敏感性、特異性及準(zhǔn)確性,對(duì)乳腺良惡性病變的診斷與鑒別診斷具有很高的臨床價(jià)值,是最佳診斷組合序列。非增強(qiáng)組合序列對(duì)乳腺良惡性病變的診斷有一定優(yōu)勢(shì),可作為乳腺疾病篩查的MRI技術(shù)。
[Abstract]:Objective: to evaluate the value of Mr diffusion weighted imaging combined with different imaging sequences in the qualitative diagnosis of benign and malignant breast lesions. 29 cases of malignant lesions (32 lesions) proved by surgery and pathology of benign and malignant breast lesions of MRI data, pathological diagnosis as the gold standard, The sensitivity of T1WI combined with DWI(T_1WI DWI / T 2WI combined with DWI(T_2WI DWI (DCE + DWI(DCE DWI) in the diagnosis of benign and malignant breast lesions was statistically analyzed and compared. Results the sensitivity of the four diagnostic methods to the diagnosis of benign and malignant breast lesions was 81.3% and 90.6% and 93.796.8 respectively. The specificity was 83.9% and the specificity was 83.9%. The specificity was 83.9%, and the accuracy was 76.911%. Conclusion the diagnostic sensitivity of the two methods is higher than that of the control group. Conclusion the diagnostic sensitivity of the two groups is higher than that of the control group, and the accuracy is 76.911 / 91C / 91C / 99.99.Conclusion there is a high sensitivity in the diagnosis of benign and malignant breast lesions. [WT5HZ] [WT5BZ] [WT5BZ] the sensitivity of DCE combined with DWI in the diagnosis of benign and malignant breast lesions is higher than that in the control group. Specificity and accuracy have a high clinical value in the diagnosis and differential diagnosis of breast benign and malignant lesions, and are the best combination sequence. Non-enhanced combination sequence has some advantages in the diagnosis of benign and malignant breast lesions. It can be used as MRI technique for breast disease screening.
