Clinical Implementation
Value Proposition
Lipohemarthrosis of the knee occurs when there has been a fracture of one of the bones of the knee. It occurs because fatty material from inside the central part of the bone spills into the joint space after a fracture. The presence of a lipohemarthrosis often alerts the radiologist to the presence of a fracture when one is not otherwise visible. When a lipohemarthrosis is missed by the radiologist, can result in a delay of care for the patient.
Narrative
A 58 year old woman slips on ice and has knee pain and swelling. While there is no obvious fracture seen on the x-ray, there is significant swelling which can be caused by other things such as ligamentous damage. The AI algorithm detects the presence of a lipohemarthrosis and alerts the radiologist to the finding. This prompts the radiologist to more closely evaluate the radiograph or order a CT to determine the source of the lipohemarthrosis.
Workflow Description
The knee radiograph is processed by the algorithm which is tuned to evaluate for fluid-fluid levels. The engine would send a message to PACS with the coordinates of the suspicious finding and would alert the radiologist if it is present.
