AI-enabled CCTA on par with IVUS for plaque quantification

An AI-powered automated plaque quantification tool for coronary CT angiography (CCTA) performs on par with intravascular ultrasound (IVUS) for quantifying heart plaque volume and characterizing plaque.

Representative maximum-intensity projections of five patients (patients 3, 5, 7, 10, and 11) comparing Ga-68 NYM046 and F-18 FDG. Both tracers showed specific retention in bone and lymph node metastases (patients 10 and 11). Ga-68 NYM046 PET/CT outperformed F-18 FDG PET/CT in detecting primary tumors, lung metastases, and pleural metastases (patients 3, 5, 7, and 11).
