NEURORADIOLOGY COMPUTED TOMOGRAPHY
Head without IV contrast: headaches, dementia, trauma, bleeds, stroke
Head pre-/post-contrast: tumor, infection, AVM
Head CT angiography: aneurysm detection, vascular stenoses/occlusions
Facial trauma: orbital floor fractures, complex fracture characterization
Sinus: sinusitis, nasal septal deviation
Sinus with IV contrast: sinus tumors/polyps
Orbital screen: assess for metallic foreign bodies before MR scan
Orbits with IV contrast: orbital tumors
Temporal bones: mastoiditis, cholesteatomas, congenital abnormalities
Temporal bones with IV contrast: vascular middle/inner ear masses
Neck with IV contrast: palpable mass, tumor staging, abscess detection
Neck CT angiography: carotid stenoses and occlusions, dissection
Larynx scan: hoarseness, laryngeal tumor, vocal cord paralysis
NEURORADIOLOGY MAGNETIC RESONANCE IMAGING
Brain without IV contrast: headaches, dementia, stroke
Brain pre-/post-contrast: tumors, infection, AVM
Trauma/hemorrhage scan: detect occult bleeds or cavernous angiomas
Seizure scan: 1st time seizure (with IV contrast), epilepsy, mesial temporal sclerosis
Demyelinating disease (MS protocol): evaluate for plaques
Internal auditory canal: vertigo, tinnitus, detect acoustic schwannomas
Pituitary evaluation: macro- and micro-adenoma detection, optic chiasm mass effect
Orbital evaluation: orbital masses, optic neuritis
Cavernous sinus evaluation: cavernous sinus thrombosis
Trigeminal neuralgia: mass or vessels impinging on cranial nerve V
Neck MR angiography: carotid stenoses and occlusions, dissection
Brain MR angiography without IV contrast: stenoses and occlusions, aneurysms
N1, N11, and N12 combined
Neck with IV contrast: palpable mass, tumor assessment
Temporomandibular joint: TMJ pain and displacement
Brachial plexus: Pancoast tumors, metastases, radiation fibrosis
Sacral plexus: Impinging masses, traction injuries
