CT Head Without and With IV Contrast There is no relevant literature to support the use of CT head without and with IV contrast in the initial imaging evaluation of headache with features of intracranial hypotension. CT Head Without IV Contrast There is no relevant literature to support the use of CT head without IV contrast in the initial imaging evaluation of headache with features of intracranial hypotension. CTA Head With IV Contrast There is no relevant literature to support the use of CTA head with IV contrast in the initial imaging evaluation of headache with features of intracranial hypotension. CTV Head With IV Contrast There is no relevant literature to support the use of CTV head with IV contrast in the initial imaging evaluation of headache with features of intracranial hypotension. Headache 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 hypotension. 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 hypotension. 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 hypotension. MRI Head Without and With IV Contrast MRI head without and with IV contrast is useful in the initial imaging evaluation of headache with features of intracranial hypotension. The most common brain MRI findings include pachymeningeal enhancement (reported in 83% of patients), subdural fluid collections, brain/brainstem sagging, downward displacement of cerebellar tonsils, distension of venous structures/sinuses, and enlargement of the pituitary gland. Orbital findings include a collapsed optic nerve sheath and a straightened optic nerve angle.
