目的 :探讨乳腺MR检查中常见的生理性胸腔积液量的正常值范围及左右两侧发生率。方法 :回顾本院2012年654例行乳腺MR检查患者的资料,对其中符合条件的469例患者的MR图像进行分析。于平扫T2-tirm序列图像测量胸壁前缘生理性胸腔积液厚度的最大值,厚度即代表胸腔积液的定量。对左右两侧生理性胸腔积液的厚度及发生率进行Wilcoxon符号秩和检验及Mc Nemar检验。结果:469例患者中,300例(63%)发现生理性胸腔积液,182例(38.8%)单侧发生,118例(25.2%)双侧。右侧胸腔积液厚度为(3.63±1.63)mm,范围(1.1~11.4)mm,左侧(2.91±1.60)mm,范围(1.1~11.2)mm,差异有统计学意义(P﹤0.001);右侧发生率为62.7%(294/469)高于左侧26.4%(124/469),差异有统计学意义(P﹤0.05)。结论:生理性胸腔积液在乳腺MR检查中较为常见,T2-tirm序列图像易于观察,右侧发生率较左侧高。如为生理性不需要做进一步检查及处理。
Objective: To investigate the range of normal range of physiological pleural effusion and the incidence of bilateral left and right common breast MR examination. Methods: The data of 654 breast MR patients in our hospital from 2012 to 2012 were retrospectively analyzed. MR images of 469 eligible patients were analyzed. T2-tirm in plain scan sequence images of the front of the chest wall thickness of physiological pleural effusion, the thickness that represents the quantification of pleural effusion. The left and right physiological pleural effusion thickness and incidence Wilcoxon signed rank sum test and Mc Nemar test. RESULTS: Of the 469 patients, 300 (63%) had physiological pleural effusions, 182 (38.8%) unilateral and 118 (25.2%) bilateral. The thickness of the right pleural effusion was (3.63 ± 1.63) mm in the range of 1.1 to 11.4 mm and the left was 2.91 ± 1.60 mm in the range of 1.1 to 11.2 mm, with significant difference (P <0.001). The incidence of the right side was 62.7% (294/469) higher than the left side of 26.4% (124/469), the difference was statistically significant (P <0.05). Conclusion: Physiological pleural effusion is more common in breast MR examination. T2-tirm sequence images are easy to observe, and the incidence of right side is higher than left side. If the physiological does not require further examination and treatment.
