Clinical Implementation

Value Proposition

Identification and enumeration of rib fractures is a time consuming and tedious process in trauma radiology. Emergency radiologists would benefit greatly by having an automated process to identify rib fractures and report which ribs are fractured. Such an algorithm would decrease time to report and increase accuracy in reporting of rib fractures. This becomes even more valuable as surgical stabilization of rib fractures becomes increasingly utilized, with surgical selection criteria based on the number and conformation of fractures.

Narrative(s)

75 year old woman is involved in a high-speed motor vehicle crash, suffering blunt chest trauma. There is clinical concern for flail chest and chest CT is performed.

Workflow Description

Image obtained from CT scanner and sent to PACS and the AI engine. Image analyzed by engine. System detects, enumerates, and measures displacement of any rib fractures. An alert message is sent to PACS from the engine with the information, and identification, and graphic highlighting the rib fractures on all imaging planes, including 3D volume rendered imaging.
