Figure 3. Example case using the simplified LSN score + FIB-4 model: 52-year-old man with biopsy proven F3 fibrosis from chronic HCV.
A. CT image in portal venous phase shows LSN score in process. The final LSN score was 2.79. FIB-4 in this patient was 8.15
B. The probability equation for having advanced fibrosis is shown. When plugging in the values for this patient, the probability is 1.0, indicating the patient almost certainly will have advanced fibrosis or cirrhosis. Boxplots of probabilities is shown for the entire cohort.
