【摘要】：目的比较自动乳腺全容积扫查(ABVS)与MRI诊断乳腺病灶的价值。方法收集乳腺肿块患者70例,共77个病灶,均经手术后病理证实。分析其ABVS和MRI图像特征,并比较二者评估乳腺病灶大小和诊断病灶良恶性的效能,评估ABVS冠状面上的"汇聚征"对乳腺恶性肿块的诊断效能。结果 70例患者中,良性37例(共43个病灶),恶性33例(共34个病灶)。ABVS[(18.0±8.9)mm]和MRI[(17.0±9.0)mm]测得病灶最大值与病理测值[(17.8±9.2)mm]均呈正相关(r=0.96、0.95,P0.01),但ABVS和MRI所测病灶最大值差异无统计学意义(P0.05)。ABVS和MRI诊断乳腺肿块的敏感度、特异度、准确度、阳性预测值和阴性预测值分别为91.18%(31/34)和85.29%(29/34)、86.05%(37/43)和90.70%(39/43)、88.31%(68/77)和88.31%(68/77)、83.78%(31/37)和87.88%(29/33)、92.50%(37/40)和88.64%(39/44),ROC曲线下面积分别为0.96、0.95(P0.05)。"汇聚征"阳性率为32.47%(25/77),在良、恶性病灶中分别占6.98%(3/43)和64.71%(22/34),差异有统计学意义(2χ=6.87,P0.01)。ABVS重建冠状面"汇聚征"对乳腺肿瘤良恶性鉴别诊断的敏感度、特异度、准确度、阳性预测值和阴性预测值分别为64.70%(22/34)、93.02%(40/43)、80.52%(62/77)、88.00%(22/25)和76.92%(40/52)。结论 ABVS和MRI均能有效诊断乳腺肿块,但ABVS对乳腺肿块的诊断敏感度更高,其冠状面的"汇聚征"能有效鉴别乳腺肿块的良恶性。
[Abstract]:Objective to compare the value of (ABVS) and MRI in the diagnosis of breast lesions. Methods 70 cases (77 lesions) of breast masses were collected and confirmed by operation and pathology. The characteristics of ABVS and MRI images were analyzed, the size of breast lesions and the effectiveness of diagnosis of benign and malignant lesions were compared, and the diagnostic efficacy of "convergence sign" on ABVS coronal plane for breast malignant masses was evaluated. Results of the 70 patients, In 37 cases of benign lesions (43 lesions), 33 cases of malignant lesions (34 lesions), 33 cases of malignant lesions [(18.0 卤8.9) mm] and MRI [(17.0 卤9.0) mm] were positively correlated with pathological values [(17.8 卤9.2) mm], but there was no significant difference between ABVS and MRI (P0.05), ABVS and MRI in the diagnosis of breast masses. The specificity, accuracy, positive predictive value and negative predictive value were 91.18% (31 / 34) and 85.29% (29 / 34), 86.05% (37 / 43), 90.70% (39 / 43), 88.31% (68 / 77) and 88.31% (r / 6877), 83.78% (31 / 37) and 87.88% (2933) / 92.50% (37 / 40) and 88.64% (39 / 44), respectively. The positive rate of convergence sign was 32.47% (25 / 77), 6.98% (3 / 43) and 64.71% (22 / 34) of benign and malignant lesions, respectively. The difference was statistically significant (蠂 ~ 2 / 6.87 / P0.01). The positive and negative predictive values were 64.70% (22 / 34), 93.02% (40 / 43), 80.52% (62 / 77), 88.00% (22 / 25) and 76.92% (40 / 52), respectively. Conclusion both ABVS and MRI can effectively diagnose breast masses, but ABVS is more sensitive to the diagnosis of breast masses. The coronal "convergence sign" can effectively distinguish benign and malignant breast masses.
