Risk Factors Influencing Right and Left Ventricular Variables Assessed with Gated Cadmium–Zinc–Telluride Equilibrium Radionuclide Angiocardiography in Oncology Patients

Diagnostics
Background: Left ventricular ejection fraction remains the primary focus in cardiac monitoring for oncology patients undergoing potentially cardiotoxic chemotherapy, while right ventricular function is seldom examined.

Right ventricular ejection fraction: Comparison of technetium-99m first pass technique and ECG-gated steady state krypton-81m angiocardiography

, 1986
Right ventricular ejection fraction (RVEF) calculated from ECG-gated steady-state 81mKr angiocardiography and from 99mTc first-pass studies were compared in 30 patients using a digital, single crystal, gamma-camera.

Non-invasive diagnosis and management of coronary arteriovenous fistula. A case report

The Turkish Journal of Pediatrics, 1997
Coronary arteriovenous fistulas are rare anomalies resulting in abnormal communication between the coronary artery and any chamber of the heart. An asymptomatic patient was referred for evaluation of her murmur.

Comparison of rest and exercise radionuclide angiocardiography and exercise treadmill testing for diagnosis of anatomically extensive coronary artery disease.

, 1983
The accuracy of rest and exercise radionuclide angiocardiography (RNA) and exercise treadmill testing (ETT) for diagnosis of three-vessel or left main coronary artery disease (extensive CAD) was determined in 544 patients.

The clinical validation of gold-195m: A new short half-life radiopharmaceutical for rapid, sequential, first pass angiocardiography in patients [PDF]

, 1983
With technetium-99m radiopharmaceuticals, first pass radionuclide angiocardiography is of limited use for multiple intervention studies because of the large radiation burden imposed on the patients.

A novel dynamic cardiac phantom for comparing blood pool and myocardial perfusion tracers: initial evaluation with CZT-ERNA and PET-MPI

EJNMMI Physics
Background Nuclear imaging modalities can quantify cardiac volumes and left ventricular ejection fraction (LVEF), but systematic differences between techniques complicate direct comparison.
