Headache of venous sinus stenosis or thrombosis in patients with suspected IIH and patients with chronic headaches, which reinforces the value of venous imaging for unexplained headaches, especially when there are features of intracranial hypertension [38-40]. Several studies have also demonstrated the increased utility of CTV with IV contrast when compared with time-of-flight MRI techniques [36,38]. MRA Head With IV Contrast There is no relevant literature to support the use of MRA head with IV contrast in the initial imaging evaluation of headache with features of intracranial hypertension. MRA Head Without and With IV Contrast There is no relevant literature to support the use of MRA head without and with IV contrast in the initial imaging evaluation of headache with features of intracranial hypertension. MRA Head Without IV Contrast There is no relevant literature to support the use of MRA head without IV contrast in the initial imaging evaluation of headache with features of intracranial hypertension. MRI Head Without and With IV Contrast Brain MRI can be useful to detect imaging signs that are associated with primary IIH and to help exclude secondary causes of elevated intracranial pressure, including structural abnormalities such as mass, edema, or hydrocephalus [37]. Although IV contrast is not required to visualize the structural alterations associated with IIH or mass/hydrocephalus, it can be useful for characterization of an intracranial mass and for depiction of the venous sinuses. MRI Head Without IV Contrast MRI head without IV contrast can be useful in the initial imaging evaluation of headache with features of intracranial hypertension. For example, brain MRI can evaluate for secondary causes of elevated intracranial pressure, including structural abnormalities such as mass, edema, or hydrocephalus. In addition, brain MRI can detect subtle findings that have been described in the literature that are associated with primary IIH.
