AN ALTERNATIVE TO IVU - MRI RARE UROGRAPHY

The authors describe the RARE sequence technique (Hennig, 1986) and its hydrographic applications including RARE urography. Heavily T2-weighted non-tomographic images of the urinary tract are obtained in less than 30 seconds, without contrast medium or ionizing radiation. The whole urinary tract is visualised on one image with a spatial resolution superior to that of sonography. The semiology of RARE urography is similar to that of the intravenous pyelogram. Silent kidneys are also visualised.
