“…The average myocardial perfusion values in patients with coronary artery stenosis less than 70% during the diastolic phase images were significantly lower than the corresponding values obtained without cardiac motion correction: SSS 5(3-7) and 6,5(5-9), (p<0,01); Stress Extent 9,5% (5,5-17,5%) and 12% (9-21,5%), (p<0,01), respectively. The average myocardial perfusion values in patients with coronary artery stenosis more than 70% in the diastole phase images were significantly higher than the corresponding values obtained without cardiac motion correction: SSS 23 (19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)) and 21 (8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22), (p<0,01); Stress Extent 44,5(35-63) and 39% (18-50%), (p=0,01), respectively. ROC analysis showed that the sensitivity and the specificity rates of MPS performed with cardiac motion correction were significantly (p < 0.05) higher compared with those obtained based on the assessment of summation images.…”

“…Решением данной проблемы является вы-полнение ЭКГ-синхронизированной записи од-нофотонной эмиссионной компьютерной томо-графии (ОФЭКТ) миокарда с дальнейшим опре-делением состояния перфузии на изображени-ях, соответствующих диастолической фазе сер-дечного цикла. Однако данный подход не мо-жет быть реализован на классических гамма-камерах (с кристаллами на основе NaI), так как изображения с отдельных фаз сердечного цикла имеют низкий сцинтиляционный счет, недоста-точный для построения качественных сцинти-грамм [10,11]. Появление новых гамма-камер, оснащенных полупроводниковыми кадмий-цинк-теллуровыми детекторами, позволяет ре-шить указанную проблему [10,11].…”

“…1,2 To these advantages, we can add its current high image quality owing to recent technical and methodological advances-i.e., semiconductor detectors, new collimation systems, and/or novel reconstruction software 1,2 -thus making MPI more reliable and relevant compared to the past. Moreover, as it can now be performed with a much lower radiation exposure, this evolution is particularly favorable for the growing number of patients referred for repeated ionizing procedures throughout the course of their life.…”

“…5 However, IHD and other forms of atherosclerotic diseases still remain the leading cause of death worldwide and have been projected to remain as such until at least the year 2030. 6 Thus, further progress is now needed (1) to decrease the number of individuals being detected too late, as well as to detect those individuals who do not reach their treatment goals; 7,8 and (2) focused on tailored prevention strategies and early risk prediction with the help of dedicated risk algorithms and diagnostic techniques.…”
