Abstract:
PURPOSE:To retrospectively examine the diagnostic values of individual parameters obtained from unenhanced and 35-second and 5-minute contrast material-enhanced (enhanced) computed tomography (CT) in distinguishing adenomas, particularly lipid-poor adenomas, from nonadenomas and to determine the best diagnostic method by using these parameters.
MATERIALS AND METHODS:This retrospective study had institutional review board approval; the need for informed consent was waived. The study population consisted of 61 patients (20 men and 41 women; mean age, 58 years) with 68 adrenal masses (53 adenomas and 15 nonadenomas). In each patient, unenhanced CT was followed by 35-second and 5-minute enhanced CT. Adenomas were classified as 30 lipid-rich (

RADIOLOGY文献大全abstract::A retrospective review of 39 cases of hypochondroplasia revealed consistent but variable degrees of clinical and radiological features sufficient to allow differentiation from other well-established metaphyseal chondrodysplasias.
