Objectives: To assess the role of power and color Doppler ultrasonography (US) in patients with azoospermia prior to testicular sperm extraction.

Methods: One hundred and thirty consecutive patients with azoospermia were assessed in this prospective study. Based on a semiquantitative method, the results of power Doppler US were graded into three categories: grade 1, no visible vessels; grade 2, between one and three detectable vessels; grade 3, more than three detectable vessels.

Background: The purpose of this study was to compare patients with multiple sclerosis and healthy control subjects as regards hemodynamics of cerebral venous drainage.

Material/methods: Between December 2012 and May 2013, 44 consecutive patients with multiple sclerosis and 44 age- and sex-matched healthy subjects underwent the B-mode, color Doppler, and duplex Doppler evaluations of the internal jugular vein (IJV) and vertebral vein. The following four parameters were investigated: IJV stenosis, reversal of postural control of the cerebral venous outflow pathways, absence of detectable blood flow in the IJVs and/or vertebral veins, and reflux in the IJVs and/or vertebral veins in the sitting or supine position.
