Nuclear Cardiology
Functional cardiac imaging for accurate ischemia assessment, viability analysis, and personalized cardiovascular management
Nuclear Cardiology for Early Detection of Coronary Artery Disease
Nuclear cardiology uses advanced imaging techniques such as SPECT and PET myocardial perfusion scans to evaluate blood flow to the heart muscle. These tests help identify early ischemia, even before symptoms become severe or ECG changes appear. By comparing rest and stress perfusion, clinicians can accurately detect obstructive coronary artery disease, assess the severity of myocardial compromise, and decide if a patient requires medical therapy, angiography, or revascularization. This leads to safer, more personalized cardiac care.
Assessing Heart Function, Viability & Prognosis with Advanced Imaging
Nuclear cardiology plays a key role in evaluating left ventricular function, myocardial viability, and overall cardiac performance. PET viability scans distinguish living but dysfunctional myocardium from scar tissue, guiding decisions about revascularization in patients with ventricular dysfunction. These tests also help predict future cardiac events, stratify risk, and optimize long-term treatment strategies. Through quantification of ejection fraction, regional wall motion, and perfusion defects, nuclear imaging supports better clinical outcomes.
Non-Invasive Evaluation of Cardiac Inflammation & Rare Cardiac Disorders
Beyond coronary artery disease, nuclear cardiology helps diagnose conditions such as cardiac sarcoidosis, myocarditis, amyloidosis, and microvascular dysfunction. FDG-PET imaging detects areas of active inflammation, helping guide immunosuppressive therapies and monitor treatment response. Nuclear scans also provide critical information in patients with unexplained arrhythmias, heart failure of unknown cause, or suspected infiltrative diseases. This non-invasive approach offers clarity in complex diagnostic situations.
