The addition of nonluminal vessel wall imaging sequences likely improves the detection of nonstenotic arterial dissection, but it is unclear whether these types of lesions would result in VBI. Because symptomatic dissection may involve any portion of the vertebral artery, from the origin at the aortic arch branch vessels to the basilar artery, the entirety of the vessel should be included for evaluation [14]. 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 VBI. MRI Cervical and Thoracic Spine Without and With IV Contrast There is no relevant literature regarding the use of MRI cervical and thoracic spine without and with IV contrast in the evaluation of suspected VBI. MRI Cervical and Thoracic Spine Without IV Contrast There is no relevant literature regarding the use of MRI cervical and thoracic spine without IV contrast in the evaluation of suspected VBI. MRI Head and Internal Auditory Canal With IV Contrast There is no relevant literature regarding the use of MRI head and IAC with IV contrast in the evaluation of suspected VBI. MRI Head and Internal Auditory Canal Without and With IV Contrast There is no relevant literature regarding the use of MRI head and IAC without and with IV contrast in the evaluation of suspected VBI. MRI Head and Internal Auditory Canal Without IV Contrast There is no relevant literature regarding the use of MRI head and IAC without IV contrast in the evaluation of suspected VBI. MRI Head Without and With IV Contrast MRI allows for detailed evaluation of the intracranial structures with improved soft tissue resolution when compared with CT. MRI before and after the administration of gadolinium-containing IV contrast allows for the additional characterization of these tissues and improved detection of intracranial pathology.
