The goal was to determine the influence of processing radiographic images with an Enhanced Visualization Processing (EVP) method on workflow in a PACS environment. Portable CR chest images were obtained and processed with either a Fuji CR unit (no EVP) or with a Kodak CR unit (EVP). A security camera with VCR for recording was positioned above the workstation. Four radiologists reviewed the images during their normal work schedule. The current diagnostic image was used to determine if the case was EVP or non-EVP. Only cases with 3 images were used in the analysis. The videotapes of the sessions were reviewed to determine diagnostic viewing times and whether zoom and/or window/level was used. Viewing time was significantly longer for the non-EVP than the EVP cases. The difference occurred with all readers, but was highest for reader 1. Window/level was used on 35% of the EVP and 41% of the non-EVP images. The difference was not significant. Zoom was used on 64% of the EVP and 69% of the non-EVP images. EVP processing of chest images displayed on PACS monitors significantly improves workflow and viewing time. It decreases (although not significantly) use of window/level, but not use of zooming.
