Overall, the diagnostic yield for head CT ordered in the emergency department for acute dizziness is low (2.2%; 1.6% for emergent findings in an academic emergency department in 448 patients), but MRI changes the diagnosis up to 16% of the time, acutely in 8% of cases [2]. CT Temporal Bone With IV Contrast There is no relevant literature regarding the use of CT temporal bone with IV contrast in the evaluation of suspected acute posterior fossa stroke. CT Temporal Bone Without and With IV Contrast There is no relevant literature regarding the use of CT temporal bone without and with IV contrast in the evaluation of suspected acute posterior fossa stroke. CT Temporal Bone Without IV Contrast There is no relevant literature regarding the use of CT temporal bone without IV contrast in the evaluation of suspected acute posterior fossa stroke. CTA Head and Neck With IV Contrast CTA head and neck may be performed for evaluation of suspected acute posterior fossa stroke, particularly those who are eligible for mechanical thrombectomy. MRA Head and Neck With IV Contrast MRA head and neck may be performed for the evaluation of acute ischemic strokes and may assist in the management of patients, particularly those who are eligible for mechanical thrombectomy. The decision between CTA and MRA for initial vascular evaluation may depend on institutional preferences. MRA Head and Neck Without and With IV Contrast MRA head and neck may be performed for the evaluation of acute ischemic strokes and may assist in the management of patients, particularly those who are eligible for mechanical thrombectomy. The decision between CTA and MRA for initial vascular evaluation may depend on institutional preferences. Dizziness and Ataxia MRI Cervical and Thoracic Spine With IV Contrast There is no relevant literature regarding the use of MRI cervical and thoracic spine with IV contrast in the evaluation of suspected acute posterior fossa stroke.
