METHOD FOR DIAGNOSING THE CASES OF POSTRADIATIONAL MYOCARDIUM INJURY IN PATIENTS SUFFERING FROM PULMONARY CARCINOMA OF III STAGE AT COMBINED TREATMENT STAGES Russian patent published in 2005 - IPC

FIELD: medicine.

SUBSTANCE: method involves carrying out ultrasonic examination of heart. Tissular Doppler study of the left and right ventricle function is carried out in Tissue Tracking mode from apical access at the level of 4 chambers before intraoperative radiotherapy and 2 weeks later and then in 3, 6 and 12 months. Tissular Doppler study echocardiogram video clip is frozen in Tissue Tracking mode at the systole end. Markers are set at the center of basal, middle and apical segments of free wall of the right ventricle. Tissue Tracking curve is used for comparing maximum displacement amplitudes in every segment with their values before intraoperative radiotherapy. Maximum displacement amplitude value drop of at least one of the segments being observed, postradiational myocardium injury is to be diagnosed.

EFFECT: high accuracy and reliability of diagnosis.
