title: Evaluation of cerebral blood flow volume using color duplex sonography in patients with untreated panic disorder.
abstract: The aim of this study was to compare cerebral blood flow (CBF) using color duplex sonography in panic disorder and normal controls. We report 24 untreated patients and 20 healthy subjects. State-Trait Anxiety Inventory, Beck Depression Inventory, Beck Anxiety Inventory, and Symptom Check List-90 were completed on each subject. The internal carotid artery (ICA) and vertebral artery (VA) of both sides were explored with a 7.5-Mhz linear array transducer. CBF volume and mean ICA flow velocity were significantly higher in patients than normal subjects adjusted for age. However, we could not find a statistically significant difference in flow volume and velocity of VA and the sum of bilateral ICA volume between patients and controls adjusted for age. There was also no correlation between CBF volume and the other radiological data with STAI scores. In conclusion, we found that independent of anxiety levels, CBF volume has increased in panic disorder patients. In addition, color duplex sonography is a non-invasive and easily applicable technique and it is a preferable alternative to quantify CBF volume.
