QUESTION:

Suppose you had the following clinical situation. Write a short response about where in the medical imaging workflow an algorithm could be applied and what type of algorithm it would be (segmentation, localization, classification).

Clinical Situation: You are asked to develop an algorithm that will help emergency room clinicians know if patients have the life-threatening condition of a subdural hematoma (brain bleed) as soon as possible. The current protocol is that all images taken in the emergency room are sent to the PACS to be read by a radiologist in a first-in-first-read order. The image will need to be read by a human radiologist no matter what.

Can you describe an algorithm that might help them to read it faster? Can you describe what type of algorithm this would be and wherein the workflow such an algorithm might be applied?

ANSWER:

This would also be a classification algorithm because all that's needed is to determine whether or not a subdural hematoma exists.

Since this is an emergency diagnostic situation, you would want your algorithm to be run on the device that acquired the image, prior to it being sent to the PACS. This way, the prioritization of the image in the read queue would be done before the image got to the PACS.
