“…In cases of CCFs, proptosis with enlarged superior ophthalmic veins and orbital edema may bring attention to an asymmetrically opacified cavernous sinus in the arterial phase at CT angiography. Timeresolved MR angiography with high temporal resolution may also be useful in the diagnosis and characterization of AVF, characterized by early venous filling (50).…”

Blunt cerebrovascular injury (BCVI) is a relatively rare but potentially devastating finding in patients with high-energy blunt force trauma or direct cervical and/or craniofacial injury. The radiologist plays an essential role in identifying and grading the various types of vascular injury, including minimal intimal injury, dissection with raised intimal flap or intraluminal thrombus, intramural hematoma, pseudoaneurysm, occlusion, transection, and arteriovenous fistula. Early identification of BCVI is important, as treatment with antithrombotic therapy has been shown to reduce the incidence of postinjury ischemic stroke. Patients with specific mechanisms of injury, particular imaging findings, or certain clinical signs and symptoms have been identified as appropriate and cost-effective for BCVI screening. Although digital subtraction angiography was previously considered the standard examination for screening, technologic improvements have led to its replacement with computed tomographic angiography. Of note, although not appropriate for screening, improvements in magnetic resonance angiography with vessel wall imaging hold promise as supplemental imaging studies that may improve diagnostic specificity for vessel wall injuries. Understanding the screening criteria, imaging modalities of choice, imaging appearances, and grading of BCVI is essential for the radiologist to ensure fast and appropriate diagnosis and treatment. This article details the imaging evaluation of BCVI and discusses the clinical and follow-up imaging implications of specific injury findings. RSNA, 2018.

with no previous or concomitant symptoms of thyroid disorders, lack of symptoms of eyelid retraction, divergent strabismus, diplopia as the only symptom of the disease, and a history of increasing diplopia at the end of the day.The inflammatory activity and severity of TO should be diagnosed based on personal experience and according to standard diagnostic criteria. Assessment of TO inflammatory activity can be performed using the clinical activity score (CAS). Magnetic resonance imaging (MRI) is not necessary to diagnose typical cases of TO but may be necessary to assess the inflammatory activity of TO, especially in those with a so-called "posterior" course. Orbital MRI is indicated in patients with unilateral or highly asymmetric exophthalmos, suspected optic nerve neuropathy, and TO with euthyroidism, while computed tomography (CT) of the orbit is par-

“…Characteristically, early venous filling during the arterial phase in AVFs may be difficult to detect with single-phase CT angiography. Other features such as dilated draining veins may provide a clue to the diagnosis, and time resolved MR angiography may also be helpful [32]. Arterial transection with free extravasation of contrast represents the most severe form of BCVI.…”

Blunt cerebrovascular injury (BCVI) is an often underrecognized injury occurring in the carotid or vertebral arteries, associated with a risk of ischemic stroke and potential for poor neurological outcome or death. Computed tomographic angiography (CTA) is the most common modality for initial screening and diagnosis. Vessel wall intimal injuries, intraluminal thrombus, dissection, intramural hematoma, pseudoaneurysm, vessel transection, and arteriovenous fistula, are potential findings to be considered in approach to imaging. Identification of high-risk trauma patients based on clinical and radiological risk factors can determine patients at risk of BCVI for targeted screening.
