The Diagnostic Advice Module presents an interpretation regarding perfusion defects and cardiac function that can be used as a Quality Assurance tool to secure the reporting process.
The advice is based on Artificial Neural Networks that have been trained using large databases of cardiac scans interpreted by top experts in the field. This technique is superior to conventional scoring techniques. Physicians have been shown to increase their sensitivity to ischaemia using the advice [Ref 1].
The gender-specific normal values for cardiac function are based on a group of 185 patients with normal perfusion.
