Purpose. To use transcranial Doppler (TCD) sonography to determine if patients with migraine without aura have interictal hemodynamic abnormalities compared with patients who have episodic tension‐type headache (TH). Methods. Thirty‐six migraine patients without aura and 51 TH patients (age range, 16–50 years) who were diagnosed according to the criteria of the International Headache Society 1988 participated in the study. Forty‐four healthy volunteers, matched for age and sex, formed the control group. Time‐averaged mean velocity (TAMV), pulsatility index (PI), and breath‐holding index (BHI) were measured via TCD sonography in the middle cerebral artery. Results. TAMV was higher in migraine without aura than in episodic TH ( p = 0.034). There were no differences between groups regarding PI or BHI. Conclusion. Our findings support the arteriolar vasodilatation theory in migraine without aura. © 2007 Wiley Periodicals, Inc. J Clin Ultrasound, 2007
