SNM SCANcast: GE adapts PET/CT for cardiac perfusion
From the Society of Nuclear Medicine meeting exhibit floor, an audio interview with Karthik Kuppusamy, Ph.D., general manger for Americas nuclear medicine, PET/CT, and cyclotron business at GE Healthcare, who touted the company’s Discovery VCT.
At this year's Society of Nuclear Medicine meeting, cardiac PET is emerging from the long shadow of PET/CT for oncology applications. Rejuvenated by increased Medicare reimbursements for perfusion that began this year, PET is also reaping the benefits of a growing body of research supporting its use.
On the SNM exhibit floor, Karthik Kuppusamy, Ph.D., general manger for Americas nuclear medicine, PET/CT, and cyclotron business at GE Healthcare, touted the company's Discovery VCT. The device combines 64-slice CT and high resolution PET as a one-stop shop for assessment of suspected cardiovascular disease. Discovery VCT delivers analyses of ventricular function, wall motion, and perfusion, as well as coronary CT angiograms and calcium scoring, in less than 30 minutes.
But rest and stress imaging using the Discovery VCT to identify perfusion defects presents special challenges that require the deft use of CT during pharmaceutical stress - and a special algorithm developed by GE.
Can CT-Based Deep Learning Bolster Prognostic Assessments of Ground-Glass Nodules?
June 19th 2025Emerging research shows that a multiple time-series deep learning model assessment of CT images provides 20 percent higher sensitivity than a delta radiomic model and 56 percent higher sensitivity than a clinical model for prognostic evaluation of ground-glass nodules.
