Small (<20 mm) enhancing hepatic nodules seen on arterial phase MR imaging of the cirrhotic liver: clinical implications.

摘要: OBJECTIVE. To determine the significance in patients with cirrhosis of small (<20 mm) hepatic nodules that show no hyperintensity on T2-weighted MR images but enhance during arterial phase imaging, we reviewed cases such nodules.MATERIALS AND METHODS. Our review radiology reports yielded 68 40 showed had rapid enhancement imaging after administration a gadolinium contrast agent. Thirty-four (60 nodules) multiple follow-up examinations (range length follow-up, 1-72 months; average 15 months 2 weeks). The final diagnosis nodule was determined by pathology or at least years to ensure stability and, therefore, benignity. Two radiologists independently nodules, noting size, signal intensity T1- images, and homogeneity contr...
