Reference ranges and ultrasonographic exposure conditions for pulsed Doppler sonographic studies of the fetal internal carotid artery


, : Reference ranges and ultrasonographic exposure conditions for pulsed Doppler sonographic studies of the fetal internal carotid artery. Journal of Ultrasound in Medicine 12(12): 719-722

We describe the 5th to 95th percentiles for the resistive index from the fetal internal carotid artery and measurements of (1) scanning time and (2) axial distance between transducer face and the fetal skull during pulsed Doppler examinations. Cerebral resistance peaks at 30 weeks' gestation and declines thereafter. The median duration of pulsed Doppler exposure was 31 seconds (range, 4-80 seconds), and the median transducer-skull distance was 2.2 cm (range, 1.3-6.2 cm). Our data provide reference ranges covering the entire period of fetal viability and help define ultrasonographic exposure conditions during pulsed Doppler examinations of fetal intracranial vessels.

Neurilemmomas are benign neoplasms presumedly derived from Schwann cells which rarely originate within the central nervous system. Moreover, their intraventricular location has been seldom noticed with less than 30 cases reported worldwide. Here,...
