Abstract
Objective: To evaluate anatomic factors and radiologist’s experience in the detection of solid renal masses on ultrasonography. Methods: We searched for solid renal masses diagnosed on cross-sectional imaging from 2007 to 2017 that also had previous ultrasonography from the past 6 months. The following features were evaluated: nodule size, laterality, location and growth pattern, patient body mass index and radiologist’s experience in ultrasound. In surgically resected cases, pathologic reports were evaluated. Unpaired t test and χ2 test were used [...] ABSTRACT Objective: To evaluate anatomic factors and radiologist’s experience in the detection of solid renal masses on ultrasonography.
