Magnetic resonance angiography of the renal arteries using three-dimensional balanced turbo field-echo sequence with progressive spin saturation.
We developed a new method employing a balanced turbo field-echo (b-TFE) sequence with progressive spin saturation (PSS) for magnetic resonance angiography (MRA) of the renal arteries during breath-holding without the use of contrast agents. We compared our new method with conventional dynamic MRA of renal arteries. For all portions, renal MRA using b-TFE with PSS was clearer to define (p<0.002) than did conventional dynamic MRA. We confirmed that angiography of renal arteries using b-TFE with PSS was more useful than conventional dynamic MRA.
