OBJECTIVES To evaluate the performance of mean arterial pressure, uterine artery pulsatility index and soluble endoglin level alone or in combination in screening for hypertensive disorders in pregnant women without a-priori high risk. METHODS This was a nested case-control study of women with singleton pregnancies without a-priori high risk who developed(More)
BACKGROUND A routine, multiphase, computed tomography (CT) protocol is associated with high radiation exposure to potential kidney donors. To reduce radiation exposure, several authors have suggested a reduction in the number of phases. PURPOSE To evaluate a low-radiation-dose, dual-phase protocol (i.e. a protocol with an unenhanced phase and combined(More)
