Receiver operating characteristic curves. Receiver Operating Characteristic (ROC) curves for spine and head MRI predictions. a Spine protocol achieved a ROC area under the curve (ROC-AUC) of 0.8873 for differentiating between contrast and non-contrast spine MRI. b Head MRI ROC-AUC was calculated as one vs. other categories for brain MRI routine without contrast (Routines), brain MRI with contrast (Contrasts), and Others (epilepsy, IAC, face, MRA, orbits, sella, and TMJ) and achieved a performance of 0.9463, 0.9284, and 0.9569, respectively
