Proton magnetic resonance spectroscopy and ultrasound for hepatic fat quantification

Aim:  The increasing prevalence of fatty liver disease requires routine assessment methods. Proton magnetic resonance spectroscopy (1H MRS) is increasingly used for steatosis measurement, but due to cost, is unlikely to become a widely‐used screening tool. Ultrasound is cheaper and more widely available, although subject to observer variability. Our aim was to determine the sensitivity and specificity of ultrasound against 1H MRS, using MRS as a gold standard, for the detection and quantification of hepatic fat content.
