Synopsis

Keywords: Liver, Quantitative Imaging, Quality ControlLiver fat/iron quantification with MRI is essential for detection of iron/fat overload that can lead to NAFLD and cirrhosis. The two widely used tools for this purpose are chemical shift-encoded MR sequences and HISTO. Both methods can fail due to various preventable technical factors. We analyzed various quality factors of technical acceptability for these studies and determined that >25% of all quantification studies performed over six months at our institution were technically unacceptable or had data handling errors. We then developed a checklist for MR technologists to confirm acceptability of the study and decrease potential errors before sending for interpretation.
