title: Comparison of reliabilities of the delayed images of helical renal CT in detecting small renal masses.
abstract: The reliabilities of the delayed images of helical computed tomography (CT) in detecting renal mass lesions of 30 mm or less in diameter was compared. Nephrographic, excretory and nephrographic+excretory phase images of all patients were evaluated separately to detect mass lesions of < or = 5 and 5-30 mm. There was not any statistically significant difference in the results of three groups. Nephrographic, excretory and nephrographic + excretory phase images are not different from or superior to each other in lesion detection.
