MRI Head Without IV Contrast MRI of the head may be useful in evaluating strokes in the setting of a known dissection or in the exclusion of ICH before the initiation of anticoagulation or antiplatelet therapy for a known dissection. As such, although an MRI of the head may be useful in the workup of a known dissection, there is no literature to support an MRI of the head in the initial screening examination for a suspected cervical artery dissection. MRV Head Without and With IV Contrast There is no relevant literature to support the use of MRV of the head in the initial imaging of suspected cervical vascular dissection or injury. MRV Head Without IV Contrast There is no relevant literature to support the use of MRV of the head in the initial imaging of suspected cervical vascular dissection or injury. US Duplex Doppler Carotid Artery There is no literature that supports duplex Doppler examination of the carotid in the initial imaging of suspected cervical vascular dissection or injury. US Duplex Doppler Transcranial Transcranial Doppler may be useful, both in the detection of microembolic events and in determining the hemodynamic significance of a known cervical vascular dissection. However, there is no literature to support transcranial Doppler in the initial imaging of suspected cervical vascular dissection or injury. Variant 12: Adult. Known cervical vascular dissection or injury. Surveillance imaging. Cervical cerebrovascular dissections are an important stroke etiology across all age ranges with an incidence of 2 per 100,000, accounting for 15% of all strokes [125]. The indications for neurologic imaging in the surveillance of vascular dissection vary based on the cause and severity of dissection, stability of the patient, and presence of ongoing or worsening symptoms.
