Role of imaging modalities in the management of RCVS

Role of Imaging Modalities
Transcranial Doppler sonography
    Diagnosis of vasoconstriction
    Monitoring of vasoconstriction
Noncontrast CT, CT angiography
    Detection of cerebral vasoconstriction
    Evaluation for complications such as SAH
    Provide plausible alternative diagnoses such as cerebral aneurysm
MR imaging, MR angiography
    Detection of cerebral vasoconstriction
    Evaluation for complications such as ischemic stroke
    Provide plausible alternative diagnoses such as cortical vein thrombosis
    Vessel wall imaging
Catheter angiography
    Detection of cerebral vasoconstriction, criterion standard
    Demonstration of reversibility of vasoconstriction following intra-arterial vasodilator therapy
    Possible treatment with vasodilator or balloon angioplasty
