Complementing the clinical excellence of the Nuclear Cardiac Imaging lab, Yale is involved in basic, translational and clinical research in noninvasive imaging.
The Nuclear Cardiac Imaging program at Yale is a high-volume lab (more than 4000 SPECT, PET and gated blood pool studies per year) that employs state-of-the-art technology to provide critical diagnostic and prognostic information. Our lab performs both inpatient and outpatient stress testing, optimizing the stress protocol and imaging protocol for each patient. In addition, we perform gated blood pool imaging, which we employ in the monitoring of left ventricular function in patients receiving potentially cardiotoxicity chemotherapy and in the evaluation of patients for ICD implantation.
In addition to performing myocardial perfusion imaging and gated blood pool studies, the Nuclear Cardiac Imaging lab at Yale performs PET metabolic imaging studies using fluorodeoxyglucose to evaluate myocardial viability both in patients with severely depressed left ventricular function and in patients with chronic total occlusions to guide surgical and percutaneous revascularization. We also employ metabolic imaging to evaluate cardiac sarcoidosis.
With the increasing attention being focused on reducing radiation exposure, Yale has been a leader in dose reduction. Every stress test is evaluated to determine if resting imaging is required. In addition, the Nuclear Cardiac Imaging lab has high-sensitivity cadmium-zinc-telluride cardiac-specific SPECT cameras that allow for dose reduction while maintaining excellent image quality.
