Magnetic Resonance Imaging/Elastography Is Superior to Transient Elastography for Detection of Liver Fibrosis and Fat in Nonalcoholic Fatty Liver Disease See Magnetic resonance imaging more accurately classifies steatosis and fibrosis in patients with nonalcoholic fatty liver disease than transient elastography, by Imajo K,


Magnetic resonance spectroscopy (MRS) is the only imaging modality that offers some quantitative measure-ment of hepatic fat content. In one study, MRS was shown to correlate well with histologic grading of fatty infiltration of the liver. 29 In another study, MRS accurate-ly assessed hepatic triglyceride content in 15 patients.30

Attenuation Imaging with Ultrasound as a Novel Evaluation

Mar 02, 2021 is not an imaging device, and therefore B-mode ultrasound evaluation cannot be performed at the same time [8,9]. On the other hand, many studies have shown that magnetic resonance imaging (MRI) can also quantify liver steatosis, and the accuracy of diagnosis is also quite high compared with liver biopsy [10].
