Photon-counting CT emerges as alternative for assessing fatty liver disease
By Will Morton
Photon-counting CT may serve as an alternative to MRI for assessing liver fat in patients with fatty liver disease.
September 24, 2024
Liver fat content measurement with photon-counting CT and MRI-based proton density fat fraction (PDFF). Three regions of interest (circles) were delineated in the peripheral areas of the left, right anterior, and right posterior lobes of the liver. (A) Representative axial unenhanced 120-kVp standard-dose CT image (left) and corresponding MRI scan (right) in a 33-year-old man (body mass index, 26.2) diagnosed with metabolic dysfunction-associated steatotic liver disease (MASLD) in the asymptomatic cohort. (B) Representative axial unenhanced 120-kVp low-dose CT image (left) and corresponding MRI scan (right) in a 69-year-old woman (body mass index, 24.6) in the MASLD cohort. Body mass index was calculated as weight in kilograms divided by height in meters squared.
