Validation Testing of CADe for Pulmonary Nodules
Reference standard: US certified radiologists make reference standard to indicate for patient data indicates whether or not the pulmonary nodule is present and may include such attributes as the extent or location of the pulmonary nodule. CADe device development and evaluation often relies on databases of radiology images or radiology device data with a reference standard addressing whether or not the pulmonary nodule is present within an individual patient and if so, its location and extent.
Scoring: CADe device development and evaluation often rely on determining whether the spatial location and extent of the CADe mark correspond to the location and extent of the pulmonary nodule. The scoring is processed to determine the correspondence between the CADe output and the reference standard.
Standalone performance assessment: Standalone performance assessment indicates the performance of the CADe. We compare the performance of the CADe and the predicate device. The data is processed with the CADe and the predicate device. The result will be evaluated by Free-Response Receiver Operating Characteristic (FROC) curve and the number of false-positive per case.
