It was found that patients with migraine with aura were imaged more frequently and demonstrated an increased incidence of minor intracranial abnormalities such as lacunar infarcts and microvascular ischemic changes. No abnormalities were detected that were of major clinical significance [24]. A study performed in China in 2018 examined 1,070 healthy control patients and 1,070 primary headache sufferers; imaging evaluation included either CT or MRI and found no statistical difference in the detection of intracranial abnormalities: 0.58% in patients with headache and 0.78% in healthy controls [25]. Headache Arteriography Cervicocerebral There is no relevant literature to support the use of cervicocerebral arteriography in the initial imaging evaluation of primary migraine or TTH with a normal neurologic examination. CT Head With IV Contrast There is no relevant literature to support the use of CT head with IV contrast in the initial imaging evaluation of primary migraine or TTH with a normal neurologic examination. 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 primary migraine or TTH with a normal neurologic examination. 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 primary migraine or TTH with a normal neurologic examination. Most studies demonstrate a very low incidence of clinically significant intracranial abnormalities in patients presenting with migraine or TTH and a normal neurological examination [25,26]. 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 primary migraine or TTH with a normal neurologic examination.
