Abstract
Objective: To analyze the morphological abnormalities on Triphasic CT scan in patients with diffuse liver disease (DLD).
Methodology: All patients who underwent the Triphasic CT study comprised the study population. Demographics, size and density of the liver, caudate-right lobe ratio (CRL) was noted. Biliary-hepatic vascular patency, hepatic venous outflow tract obstruction (HVOT), parenchymal abnormality, liver contour abnormalities, Right Posterior Hepatic Notch (PHNS) Sign, Peri-Portal Space (PPS) widening and liver segmental/lobar atrophy, if present was recorded.
Results: The study had 270 participants. Chronic liver disease (CLD) was seen in 52.6%, Budd-Chiari syndrome (BCS) in 3.3% and hepatic steatosis (HS) in 4.8%. Patients who had heterogeneous or nodular liver texture, irregular or nodular margins and segmental/labor atrophy were more likely to have CLD. A statistically significant association of PPS widening and PHNS) with the CLD group of DLD compared to other groups (p=<0.001) and HS with the female gender (p=0.011). One-way ANOVA showed the highest mean liver size (18.44cm) for BCS and lowest mean liver size (15.10cm) for CLD.
Conclusion: All the morphological abnormalities were well depicted at Triphasic CT exam. Chronic liver disease accounted for more than 4/5th of DLDs.
