Abstract

The objective of the present study was to evaluate the diagnostic efficiency of ultrasound (US) and magnetic resonance imaging (MRI) in the diagnosis and differential diagnosis of mammary duct ectasia (MDE) and breast cancer. This retrospective study was performed on 35 patients with MDE and 105 patients with breast cancer using US and MRI. Imaging features, semi-quantitative and quantitative parameters were analyzed to determine their diagnostic value for MDE and breast cancer. The average age of patients with breast cancer was increased compared with that of patients with MDE. There were no significant differences in local packages with or without tenderness ratio (P=0.259) and grade of color Doppler flow imaging (P=0.273) between the two groups. However, the morphological changes were significantly increased in breast cancer compared with MDE. In addition, there were significant diagnostic differences in US and MRI between breast cancer and MDE, including resistance index, US elastography, time-signal intensity curve, apparent diffusion coefficient, early-stage enhancement ratio, peak-of-enhancement ratio and T (P<0.05). However, there were no observable significant diagnostic differences between US, MRI and US with MRI for MDE and breast cancer (P=0.103, P=0.263 and P=0.403 respectively). Diagnosis of MDE and breast cancer requires full evaluation of multiple parameters and morphological changes of US and MRI to increase the diagnostic efficiency. US, MRI and US with MRI were all of diagnostic value for MDE and breast cancer, while US with MRI had the highest efficacy.

摘要

本研究的目的是评估超声（US）和磁共振成像（MRI）在乳腺导管扩张症（MDE）和乳腺癌的诊断及鉴别诊断中的诊断效能。本回顾性研究对35例MDE患者和105例乳腺癌患者进行了US和MRI检查。分析成像特征、半定量和定量参数，以确定它们对MDE和乳腺癌的诊断价值。与MDE患者相比，乳腺癌患者的平均年龄有所增加。两组之间有无压痛包块比例（P = 0.259）和彩色多普勒血流成像分级（P = 0.273）无显著差异。然而，与MDE相比，乳腺癌的形态学改变明显增加。此外，乳腺癌和MDE在US和MRI方面存在显著的诊断差异，包括阻力指数、US弹性成像、时间-信号强度曲线、表观扩散系数、早期强化率、强化峰值率和T（P < 0.05）。然而，对于MDE和乳腺癌，US、MRI以及US联合MRI之间未观察到显著的诊断差异（分别为P = 0.103、P = 0.263和P = 0.403）。MDE和乳腺癌的诊断需要全面评估US和MRI的多个参数及形态学改变，以提高诊断效率。US、MRI以及US联合MRI对MDE和乳腺癌均具有诊断价值，而US联合MRI的效能最高。
