Others
NO
To assess feasibility of virtual non-contract CT imaging in the evaluation of fat quantification of the liver in comparison with real non-contrast images.
Efficacy
Confirmatory
The visual detectability of fatty liver by using needle biopsy as reference standard.
(1) ROI assessment of the liver parenchyma and the spleen
(2) Radiation dose
Observational
20 | years-old | <= |
Not applicable |
Male and Female
Patients who will undergo dynamic contrast-enhanced CT of the liver due to suspected or known fatty liver disease within 4 weeks prior to liver biopsy.
Patients with severe comorbidities which can pose a problem for performing CT exam
Images with non-diagnostic image quality caused by presence of artifacts or inadequate scan timing
Multiple liver masses
Abnormal hemodynamics in the liver due to portal venous thrombosis, etc.
Patients ineligible for dynamic contrast-enhanced CT due to other reason
