METHOD FOR PREDICTION OF RISK OF DEVELOPING PORTAL HYPERTENSION IN DIFFUSE LIVER DISEASES Russian patent published in 2021 - IPC A61B6/03 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, to radiation diagnostics, and can be used for prediction of risk of developing portal hypertension in diffuse liver diseases. Performing T2 (transverse relaxation time), T1 (longitudinal relaxation time) of weighted images (WI) of liver in magnetic resonance tomography. Study is carried out in the mode of proton spins marking with magnetic field in arterial water molecules (ASL – perfusion). Serous scale hepatic blood flow (HBF) maps are obtained in ml/100 g/min – quantitative assessment, and color maps – qualitative assessment. If HBF is 131–160 ml/100 g/min, a blue map indicates a low risk of developing portal hypertension. If the HBF is from 40 to 130 ml/100 g/min, the blue-type map indicates the average risk. If HBF is 161 to 185 ml/100 g/min, a red map indicates a high risk. If HBF is 131–160 ml/100 g/min, the red map is a very high risk.

EFFECT: method provides a low-cost qualitative and quantitative assessment of the risk of developing portal hypertension in patients with diffuse liver diseases; method provides the prediction of the risk of developing portal hypertension in diffuse liver diseases by qualitative and quantitative criteria.
