As in most other nuclear medicine facilities, tomographic myocardial imaging was started here with the patients in the supine position. However, previous planar imaging experience indicated a high number of false-positive results using the supine position for left lateral views of the myocardium. Evaluating the accuracy of supine position SPECT imaging was considered necessary. In 1991, 228 myocardial imaging procedures were performed during a period of 3 months. Coronary arteriography followed within 3 months in 67 of these patients, permitting evaluation of the accuracy of the imaging procedure interpretations. These correlations revealed the accuracy of myocardial imaging to be only 73%. This was caused mainly by a rather large number of false-positive results (24%) occurring mostly in the inferior-posterior wall. A similar comparison was performed in 1992 after a change to prone position for routine tomographic myocardial imaging with 63 of 295 patients undergoing coronary arteriography. These data revealed an increase in the overall accuracy to 81% and a decrease in the false-positive results to 16%. The improvements were almost entirely in the inferior-posterior regions with no significant change in the false-positive results in the anterior wall. These findings provide convincing evidence that the prone position should be selected for tomographic myocardial imaging.

The prognostic value of easily accessible hematologic biomarkers, such as the neutrophil-to-HDL ratio, as well as the monocyte-to-HDL, lymphocyte-to-HDL, and platelet-to-HDL ratios, remains underexplored in patients with established ischemic heart disease (IHD). Community-dwelling adults aged ≥ 20 with established IHD from the National Health and Nutrition Examination Survey (NHANES) 1999-2018 were eligible. Mortality was tracked through linkage to the National Death Index (NDI) until the end of 2019.

Pulmonary embolism (PE) is a life-threatening medical condition caused by the thrombotic occlusion of one or more branches of the lung vasculature, which represents the third most common cause of cardiovascular mortality after myocardial infarction and stroke. PE treatment requires a tailored approach based on accurate risk stratification and personalized treatment decision-making. Anticoagulation is the cornerstone of PE management, yet patients at higher clinical risk may require more rapid reperfusion therapies.

, a common cause of gastroenteritis worldwide, has also been associated with rare extraintestinal infections, including myocarditis. We report a unique case of a 24-year-old male who presented with febrile diarrhea and acute chest pain. Diagnostic investigations revealed elevated cardiac troponin levels, normal electrocardiography findings, and myocardial inflammation on cardiac magnetic resonance imaging, confirming the diagnosis of acute myocarditis.

: To validate the automated quantification of cardiac chamber volumes and myocardial mass on non-contrast chest CT using cardiac MR (CMR) as a reference. : We retrospectively included 53 consecutive patients who received non-contrast chest CT and CMR within three weeks. A deep learning model created cardiac segmentations on axial soft-tissue reconstructions from CT, covering all four cardiac chambers and the left ventricular myocardium.
