One of the coronary disease diagnostic methods of big sensitivity and specificity is perfusive effort scintrigraphy of myocardium by means of thallium-201. For few years the dipyridamole test has been applied instead of the effort test. Perfusive scintigraphy of myocardium after provocative treatment by means of dipyridamole and then selective coronary arteriography of coronary vessels, have been carried out at 25 patients with ischemia. These studies showed almost 100% of conformability with exposing the ischemia zones in scintigraphy and coronary arteriography in cases of coronary vessels contraction over 50%. The dipyridamole test also revealed the ischemzones in myocardium that are in agreement with coronary vascularization deficiency. That test can be utilized in revealing the coronary disease and is helpful in qualifying patients for coronary arteriography. At the same time studies that have been carried out prove that applying dipyridamole is absolutely contraindicated in treating of coronary disease of the organic background.

Feasibility of on-site CT-FFR analysis on cardiac photon-counting CT in evaluation of hemodynamically significant stenosis in comparison to invasive catheter angiography.

Objectives: Coronary CT angiography (CCTA) is an excellent tool in ruling out coronary artery disease (CAD) but tends to overestimate especially highly calcified plaques. To reduce diagnostic invasive catheter angiographies (ICA), current guidelines recommend CT-FFR to determine the hemodynamic significance of coronary artery stenosis. Photon-Counting Detector CT (PCCT) revolutionized CCTA and may improve CT-FFR analysis in guiding patients.

Objectives: The coronary heart disease (CHD) can influence the development of several diseases. The presence of CHD is correlated to a higher incidence of concurrent diabetic retinopathy (DR) in previous study. Herein, we aim to analyze the relationship between the CHD severity and following DR with different severity.

Aims: To identify differences in CT-derived perivascular (PVAT) and epicardial adipose tissue (EAT) characteristics that may indicate inflammatory status differences between post-treatment acute myocardial infarction (AMI) and stable coronary artery disease (CAD) patients.

Methods And Results: A cohort of 205 post-AMI patients (age 59.8±9.

This paper proposes the use of artificial intelligence techniques, specifically the nnU-Net convolutional neural network, to improve the identification of left ventricular walls in images of myocardial perfusion scintigraphy, with the objective of improving the diagnosis and treatment of coronary artery disease. The methodology included data collection in a clinical environment, followed by data preparation and analysis using the 3D Slicer Platform for manual segmentation, and subsequently, the application of artificial intelligence models for automated segmentation, focusing on the efficiency of identifying the walls of the left ventricular. A total of 83 clinical routine exams were collected, each exam containing 50 slices, which is 4,150 images.
