摘要
Abstract
Objective To characterize the differences in radiologic features between benign and malignant adrenal lesions. Methods Enhanced multiple-slice spiral CT images of 99 patients with adrenal tumors were reviewed retrospectively, investigating into morphological features of different kinds of adrenal lesions with Wash-in Amplitude (WA. Venous phase attenuation- unenhanced attenuation) and relative wash-in ratio (RWR, WA/artery phase attenuation). Results A combination of threshold in diameter =3. 2 cm, unenhanced attenuation = 24 HU, and RWR value =0. 879 produced 94. 28% sensitivity and 98. 43% specificity in diagnosing adenomas. Conclusion Enhanced CT imaging improves diagnostic accuracy of incidental adrenal lesions.关键词
