Correlation of psoas muscle fat volume at baseline and maximum absolute BMI change during the course of disease. At baseline patient A (female, 48 years old, BMI 26.2 kg/m2, suffering from colorectal cancer) presented with 20.2 mL of psoas muscle fat volume, patient B (male, 64 years old, BMI 33.1 kg/m2, suffering from ductal adenocarcinoma of the pancreas) with 44.6 mL of psoas muscle fat volume. During the course of this study, patient A lost 1.7 BMI points and patient B lost 3.7 BMI points. Statistical analysis of all 22 patients with follow-ups revealed a significant correlation (r = −0.51, p = 0.02) between baseline psoas fat volume and maximum BMI change during follow-ups.
