BACKGROUND The total kidney volume (TKV) and total liver volume (TLV) increase and renal function decreases progressively in patients with autosomal dominant polycystic kidney disease (ADPKD). Somatostatin analogues, such as octreotide, reduce these increases in TKV and TLV. The aim of this study was to examine the safety of the short-term administration of(More)
PURPOSE To assess the feasibility of a new MR angiography (MRA) technique named hybrid of opposite-contrast MRA (HOP MRA) that combined the time-of-flight (TOF) MRA with a flow-sensitive black-blood (FSBB) sequence in the diagnosis of major trunk stenoocclusive diseases. MATERIALS AND METHODS On a 1.5 Tesla imager using a dual-echo three-dimensional(More)
BACKGROUND The clinical effects of increased water intake on autosomal dominant polycystic kidney disease (ADPKD) progression are unknown. METHODS ADPKD patients with creatinine clearance ≧ 50 mL/min/1.73 m(2) were divided into high (H-, n = 18) and free (F-, n = 16) water-intake groups, mainly according to their preference. Prior to the study, 30(More)
UNLABELLED The effects of imaging conditions and measures for their improvement were examined with regard to recognition of the effects of contrast on images when T1-weighted imaging with selective fat suppression was applied. METHOD Luminance at the target region was examined before and after contrast imaging using phantoms assuming pre- and post-imaging(More)
With the recent spread of three tesla (3 T) magnetic resonance imaging (MRI), time-spatial labeling inversion pulse (Time-SLIP) technique at high magnetic field can be used. The purpose of this study was to determine appropriate renal artery imaging parameters and to compare with the 1.5 T MRI image quality of a renal artery using the Time-SLIP technique.(More)
