The relevant images are obtained from the modality and sent to PACS and the AI engine based on anatomic landmarks. The images are analyzed by the engine. An algorithm evaluates the CT and, based on anatomic landmarks for the location of the pelvic adnexa, determines whether calcium is present, absent, or indeterminate by assessing the Hounsfield Units. If present, it then assesses whether there is also fat in this area by categorizing it as present, absent, or indeterminate. For cases returned where the algorithm returns to calcium or fat, the mass is measured in mm and that measurement is displayed. The radiologist is then made aware of the need for further attention to this area.
