Paper Abstract

Reviewing previously acquired images of a patient when interpreting newly acquired ones is an important aspect of clinical radiology that has received relatively little attention in specifying requirements for automated picture archiving and communications systems (PACS). This paper examines reasons that reviewing comparison images plays an essential role in radiology, and it attempts to describe the range of policies currently employed by radiology departments. Data acquired from the use of the Missouri Automated Radiology System (MARS) at the University of Chicago are presented to quantify the number of comparison examinations that exist in this patient population. The implications of storing, retrieving and displaying these comparison images are discussed under different policies for both current film file systems and PACS.
