METHOD OF ESTIMATING FUNCTIONAL DEGREE OF SEVERITY OF CORONARY ARTERY STENOSES Russian patent published in 2015 - IPC A61B6/03 A61K49/06 A61M5/00 

Abstract RU 2557702 C1

FIELD: medicine.

SUBSTANCE: water-soluble iodine-containing contrast substance is introduced to a patient intravenously, computer tomography is carried out, after which the point measurement of densitometric indices is carried out before and after obstruction in each contrasted coronary artery (CA). If the density of the contrasted CA lumen before and after obstruction at least in one of them differs by more than 80 HU, the degree of injury is considered to be haemodynamically significant, and surgical treatment is indicated to the patient.

EFFECT: method makes it possible to estimate the functional significance of CA stenosis in a single step and with high accuracy due to the integrated CT estimation of the coronary blood flow in the entire CA.
