Imagers achieve peak results while cutting gadolinium dose

March 4, 2008 Diagnostic Imaging. Imagers achieve peak results while cutting gadolinium dose Higher field magnets offer better signal-to-noise and greater sensitivity, making reduced contrast feasible in era of nephrogenic systemic fibrosis H. A. Abella ,Emily Hayes -------------------------------------------------------------------------------- At the 2007 RSNA meeting, Dr. Reza Habibi presented three lower extremity MR angiography images and asked his audience to guess which one had been performed with a low dose of gadolinium. “It’s hard to tell which belongs to the low-dose group,” said Habibi, a radiology research fellow at the University of California, Los Angeles. The images came from a new study of 3T MRA images taken on a 32-channel scanner at three different doses of gadopentetate dimeglumine (Magnevist): high (0.3 mmol/kg), intermediate (0.19 mmol/kg), and low (0.12 mmol/kg).
