CONCLUSION
Echo-planar diffusion-weighted magnetic resonance imaging (DW MRI) is more reliable than high-resolution computed tomography (HRCT) in predicting the presence and localization of cholesteatoma before tympanomastoid surgery.
OBJECTIVES
To evaluate the diagnostic accuracy of HRCT and echo-planar DW MRI in the detection and localization of cholesteatoma.
METHODS
Fifty-nine patients were prospectively included in this study. Patients with suspected primary cholesteatoma were evaluated by HRCT and echo-planar DW MRI before tympanomastoid surgery. Radiological findings were correlated with intraoperative findings.
RESULTS
HRCT and echo-planar DW MRI accurately predicted the presence or absence of cholesteatoma in 40/59 (67.8%) and 52/59 (88.1%) patients, respectively. The sensitivity, specificity, and positive and negative predictive values of HRCT were 68.97%, 66.67%, 66.67%, and 68.97%, respectively. However, sensitivity, specificity, and positive and negative predictive values of echo-planar DW MRI were 85.71%, 90.32%, 88.89%, and 87.50%, respectively.
结论
在鼓室乳突手术前预测胆脂瘤的存在及位置方面，回波平面扩散加权磁共振成像（DW MRI）比高分辨率计算机断层扫描（HRCT）更可靠。
目的
评估HRCT和回波平面DW MRI在胆脂瘤检测及定位中的诊断准确性。
方法
本研究前瞻性纳入59例患者。疑似原发性胆脂瘤患者在鼓室乳突手术前行HRCT和回波平面DW MRI检查。将影像学检查结果与术中所见进行对照。
结果
HRCT和回波平面DW MRI分别在40/59（67.8%）和52/59（88.1%）的患者中准确预测了胆脂瘤的存在与否。HRCT的敏感性、特异性、阳性预测值和阴性预测值分别为68.97%、66.67%、66.67%和68.97%。然而，回波平面DW MRI的敏感性、特异性、阳性预测值和阴性预测值分别为85.71%、90.32%、88.89%和87.50%。
