Software Discrepancies in Radionuclide-Derived Left Ventricular Ejection Fraction.

Gated equilibrium radionuclide angiography (ERNA), or multigated acquisition scanning, is a well-established technique to monitor left ventricular ejection fraction (LVEF) in patients treated with potentially cardiotoxic chemotherapy. To determine the results of a true change in LVEF, low inter- and intrareader variability is important. The aim of this study was to investigate inter- and intrareader variability in LVEF measurements using 2 different commercially available software packages with cardiac MR (CMR) as a reference standard.

Purpose Of Review: Our purpose was to discuss the advantages and disadvantages of various noninvasive imaging modalities in the evaluation of cardiovascular disease (CVD) in patients with autoimmune rheumatic diseases (ARDs). The detailed knowledge of imaging modalities will facilitate the diagnosis and follow up of CVD in ARDs.
Recent Findings: Autoimmune Rheumatic Diseases (ARDs) are characterized by alterations in immunoregulatory system of the body.

Background: Small-molecule biomacromolecules target tumor-specific antigens. They are employed as theranostic agents for imaging and treatment. Intravenous small-molecule radioligands exhibit rapid tumor uptake and excretion.

Stress radionuclide myocardial perfusion imaging (MPI) has been well-established as a useful modality for assessing the status of the coronary circulation in post-coronary artery bypass graft (CABG) patients. CABG by itself escalates progression of atherosclerosis or thrombosis in bypassed native coronary arteries. In most cases MPI will be employed in post-CABG patients who are experiencing symptoms.

Chronic thromboembolic pulmonary disease (CTEPD) with or without pulmonary hypertension (PH) occurs when thromboemboli in pulmonary arteries fail to resolve completely. Pulmonary artery obstructions due to chronic thrombi and secondary microvasculopathy can increase pulmonary arterial pressure and resistance leading to chronic thromboembolic PH (CTEPH). Mechanical interventions and/or PH medications can improve cardiopulmonary haemodynamic, alleviate symptoms, and decrease mortality risk.
