Analysis of Quantitative Data of Arterial Spin Labeling Perfusion of the Liver at Admission and Follow up of Patients with Viral Cirrhosis

The aim of this work is to analyze quantitative data magnetic resonance ASL-perfusion the liver at admission and follow up patients with viral cirrhosis. study included 34 cirrhosis: 23 (67.6 %) men 11 (32.4 women. All subjects underwent abdominal ultrasound Dopplerography vessels, shear wave elastography, Arterial spin Labeling (ASL) — Perfusion by imaging. Post-processing images was carried out, their assessment in regenerative nodules parenchyma structure out. It found that for cirrhosis according Child-Pugh Class A, regardless degree activity, values were 99.6 ± 1.8 ml/100g/min, class B 95.6 4.9 C 98.5 2.6 ml/100g/min. To determine diagnostic significance ASL-perfusion, a generalized prognosis ratio ΔM = MNBF/ MHBF calculated, where MNBF indicator volumetric blood flow nodule, hepatic surrounding parenchyma. results obtained compared elastography. For less than 101.4 predict course etiology cirrhosis, should be taken, if > 1, indicates poor (fibrosis progression), ≤ 1 favorable one (no fibrosis progression). Diagnostic prognostic ASL-liver perfusion hospital AUROC 0.865 (95 % CI 0.843–0.928) 0.915 0.881–0.946).
