Purpose: Demonstrate a clinical observation in which to establish a diagnosis it was necessary to use eight methods for diagnosing coronary pathology, four of which are radiation.

Material and methods: To establish a diagnosis in a cardiac patient with suspected coronary heart disease (CHD), post-infarction cardiosclerosis, echocardiography (ECG), Holter monitoring (HM), bicycle ergometry (VE), X-ray computed tomography (X-ray computed tomography) to determine calcification of the coronary arteries, single-photon selective computer tomography (SPECT), magnetic resonance computed tomography (MRI), positron emission computed tomography (PET), coronary angiography (CAG).

Results: The sequential use of eight diagnostic methods, four from radiation, was established when observing cardiosclerosis with coronary heart disease, cardiosclerosis in the 4, 5, 10, and 11 segments of the heart, complicated by a left ventricular aneurysm in the lower and lateral walls with minor ischemia at the height of physical activity.  The need to use SPECT/CT in the complex diagnosis of coronary heart disease consists of using hybrid tomography and sequentially performing two studies in one diagnostic procedure (X-ray computed tomography and SPECT with 99m Tc-technetril) it seems possible to obtain 26 study indicators (with X-ray computed tomography – 4 indicators assessing calcification of the coronary arteries, with SPECT – 11 indicators of perfusion and 11 indicators of myocardial function).

Conclusion: A clinical observation of the diagnosis of coronary artery disease with post-infarction cardiosclerosis and left ventricular aneurysm was demonstrated in which eight diagnostic technologies were used (ECG, CM, VE, CT, SPECT, MRI, PET, and CAG), four of which relate to radiation diagnostics (X-ray CT, SPECT, PET, and KAG). A feature of sequential hybrid tomography (X-ray CT and SPECT with 99mTc-technitrile) is that this technology allows you to obtain 26 research indicators.
