ABSTRACT
ObjectiveTo explore the renal functions of vasopressin-deficient Brattleboro(BB) rats by using different concentrated Gadolinium-diethylenetetramine pentaacetic acid(Gd-DTPA) dynamic enhanced magnetic resonance imaging(MRI).MethodsThe study included 14 BB rats(male rats of 3 month-old) and 14 normal male Wistar rats used as control group.Dynamic MRI was performed by using either a low dosage(0.05 mmol/kg) or a high dosage of Gd-DTPA(0.5 mmol/kg).Data of 0-60 min renal cortex,medulla and pelvic were obtained after using contrast medium.MRI of kidneys at different time was analyzed and the mean relative signal intensity(RSI) was measured.Then the RSI curves of different groups were marked.Data of each group were caculated separately by SPSS 11.0 software.ResultsThe findings demonstrated that RSI curves of the vasopressin-deficient kidneys showed different patterns as compared with those of the control group(P
