Contrast-enhanced MR angiography and digital subtraction angiography in living renal donors: diagnostic agreement, impact on decision making, and costs
ثبت نشده
چکیده
Health technology The authors studied contrast-enhanced magnetic resonance angiography (MRA) and digital subtraction angiography (DSA). MR images were obtained using a 1.5-T MR scanner (Signa CV/I, GE Healthcare) with a torso phased-array coil. Digital subtraction images were obtained using a 38-cm field of view and an image matrix of 1,024 x 1,024 pixels (Integris V3000, Philips Medical Systems; or Angiostar Plus, Semaens Medical Solutions).

Background: In kidney transplantation decision about the proper kidney donation is different between surgeons, but simple vasculature anatomy and a kidney without abnormalities are the most important reasons of choosing a kidney. Therefore complete assessment of renal vessels of a live donor with noninvasive techniques is a necessity for nephrectomy. For delineation of the kidney vasculature...

BACKGROUND AND PURPOSE Contrast-enhanced MR angiography and extracranial color-coded duplex sonography are noninvasive, preoperative imaging modalities for evaluation of carotid artery stenosis. Innovative techniques and improvements in image quality require frequent reassessment of accuracy, reliability, and diagnostic value compared with those of digital subtraction angiography (DSA). We eval...
