Abstract:
Liver cirrhosis is a common chronic progressive liver disease in clinical practice, and intravoxel incoherent motion (IVIM) is a promising magnetic resonance method to assess liver cirrhosis, so our purpose was to investigate association of liver-lobe-based IVIM-derived parameters with hepatitis-B-related cirrhosis and its severity, and esophageal and gastric fundic varices. Seventy-four patients with hepatitis-B-related cirrhotic and 25 healthy volunteers were enrolled and underwent upper abdominal IVIM diffusion-weighted imaging with b -values of 0, 20, 50, 80, 100, 200, 400, 600, and 800 s/mm 2 . IVIM-derived parameters ( D , pure molecular diffusion; D ∗ , pseudo diffusion; and f , perfusion fraction) of left lateral lobe (LLL), left medial lobe (LML), right lobe (RL), and caudate lobe (CL) were assessed statistically to show their associations with cirrhosis and its severity, and esophageal and gastric fundic varices. In this research, we found that D , D ∗ , and f values of LLL, LML, RL, and CL were lower in cirrhotic liver than in normal liver (all P -values 〈 .05). D , D ∗ , and f values of LLL, LML, RL, and CL were inversely correlated with Child–Pugh class of cirrhosis ( r = −0.236 to −0.606, all P -values 〈 .05). D of each liver lobe, D ∗ of LLL and CL, and f of LLL, LML, and CL in patients with esophageal and gastric fundic varices were lower than without the varices (all P -values 〈 .05). D values of RL and CL could best identify cirrhosis, and identify esophageal and gastric fundic varices with areas under receiver-operating characteristic curve of 0.857 and 0.746, respectively. We concluded that liver-lobe-based IVIM-derived parameters can be associated with cirrhosis, and esophageal and gastric fundic varices.
