Measurement of left and right ventricular volumes with tomographic equilibrium radionuclide angiocardiography and cardiac MRI

Abstract

This study further validates SPECT ERNA as a method to measure LV and RV EF, ESV, and EDV.

Interstudy repeatability of left and right ventricular volume estimations by serial‐gated tomographic radionuclide angiographies using a cadmium‐zinc‐telluride detector gamma camera

“…However, the volumes assessed with the CZT detector camera were generally smaller (Wells et al ., ). This seems to be a general issue when changing from planar to SPECT modalities, especially in patients with small cavity hearts (Daou et al ., ; Groch et al ., ; Higuchi et al ., ; De Bondt et al ., ; Hacker et al ., ; Harel et al ., ; Clements et al ., ; Mitra & Basu, ; Wells et al ., ). The planar imaging of the 3‐dimensional cavities and the superposition of extra‐ventricular structures could lead to an overestimation of volumes.…”

Paced QRS duration predicts left ventricular function in patients with permanent pacemakers – One-year follow-up study using equilibrium radionuclide angiography (ERNA)

“…Though various imaging modalities like 2D transthoracic echocardiogram (2D-TTE), 3D transthoracic echocardiogram (3D-TTE), magnetic resonance imaging (MRI) and radionuclide imaging (RNI) studies can be utilized to measure LV function, each modality has its own merits and demerits. Unlike echocardiography radionuclide imaging is objective and has a good correlation with MRI in measuring LV function and volumes [19] . Radionuclide imaging studies are safe, feasible, and readily available at many centres and scores over MRI in post pacemaker patients due to the concerns of MRI incompatibility.…”
