The Presentation of Grouped Procedures (PGP) Integration Profile is part of the IHE Radiology Technical Framework.

This profile addresses what is sometimes referred to as the linked studies problem: viewing image subsets resulting from a single acquisition with each image subset related to a different requested procedure (e.g. CT chest, abdomen, and pelvis).

This profile provides a mechanism for facilitating workflow when viewing images and reporting on individual requested procedures that an operator has grouped (often for the sake of acquisition efficiency and patient comfort). A single acquired image set is produced, but the combined use of the scheduled workflow transactions and the consistent presentation of images allow separate viewing and interpretation of the image subsets related to each of the requested procedures.
