PERCIST's Potential: PET & Quantification

摘要

PET is a quantitative modality, yet most reports are qualitative and descriptive, rather than quantitative, explains Richard L. Wahl, MD, director of nuclear medicine/ PET at Johns Hopkins University School of Medicine in Baltimore. "We developed PERCIST because there is a lot of variability across practices in terms of PET interpretation." PERCIST, along with related initiatives such as RSNA's Quantitative Imaging Biomarker Alliance, aims to standardize PET protocols. The goal, says Wahl, is to transform PET from an imaging device to an imaging and quantitation device.
