OBJECTIVE: To evaluate low-dose @entity23432 -enhanced MRI for the differential diagnosis of @entity703 . METHODS: Sixty-two consecutive @entity1 with unclear diagnosis at MDCT/ultrasound underwent dynamic CE-MRI of the kidneys with 0.05  mmol/kg @entity23432 . Retrospective image evaluation was performed by two blinded readers. Lesion diagnosis at CE-MRI was correlated with findings from histology following @entity5 resection or from imaging follow-up after at least 1  year. Assessments were performed of diagnostic quality and level of diagnostic information. RESULTS: Thirty-nine (63  %) @entity1 were correctly diagnosed with @entity5 (36 with @entity1358 , 2 with renal metastases, 1 with @entity706 ) while 14 (22.6  %) @entity1 were correctly diagnosed with benign (n  =  12) or no (n  =  2) lesions. Eight @entity1 were considered false positive (5 with @entity1637 , 3 with @entity3052 ) and 1 @entity1 false negative (atypical @entity1358 ). The sensitivity, specificity, accuracy, @entity2286 , and NPV for the diagnosis of @entity8 were 97.5  % (39/40), 63.6  % (14/22), 85.5  % (53/62), 83.0  % (39/47), and 93.3  % (14/15), respectively. Images were excellent in 60 and good in 2 @entity1 . Minimal artifacts that did not compromise diagnosis were noted in 4/62 @entity1 . CONCLUSION: Low-dose @entity23432 -enhanced MRI is effective for the differential diagnosis of @entity703 .
