CTV Head With IV Contrast CTV head with IV contrast can be useful in the initial imaging evaluation of new headache during pregnancy or peripartum period, as this patient demographic is at a higher risk for thromboembolic complications such as CVT, especially in the postpartum period [12,49]. In pregnant patients requiring contrast-enhanced evaluation of the dural venous sinuses, CTV is the modality of choice because iodinated contrast agents are generally considered safer than gadolinium-based contrast agents (GBCA) with regard to potential effects on the fetus. After an initial head CT, a concurrent or follow-up CTV is useful in suspected cases of venous thrombosis. 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 new headache during pregnancy or peripartum period; the recommendation is to avoid administering IV GBCA during pregnancy. 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 new headache during pregnancy or peripartum period; the recommendation is to avoid administering IV GBCA during pregnancy. 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 new headache during pregnancy or peripartum period. In some scenarios, brain MRA may be useful following or in conjunction with brain MRI when evaluating for cerebrovascular etiologies of headache such as RCVS [12,52]. Headache MRI Head With IV Contrast There is no relevant literature to support the use of MRI head with IV contrast in the initial imaging evaluation of new headache during pregnancy or peripartum period; the recommendation is to avoid administering IV GBCA during pregnancy.
