Uterine artery embolization for leiomyomas: percentage of infarction predicts clinical outcome.

Purpose: To determine the effect of partial versus complete leiomyoma infarction on relief of leiomyoma-related symptoms and freedom from invasive reinterventions and to assess if patient age, location of the dominant leiomyoma, number of leiomyomas, or baseline uterine and dominant leiomyoma volume were associated with clinical failure.

Materials And Methods: Study protocol was approved by the institutional review board, and informed consent was obtained. One hundred fifteen consecutive women (median age, 42 years; range, 34-61 years) with symptomatic uterine leiomyomas underwent contrast material-enhanced magnetic resonance (MR) imaging at baseline and 24-72 hours after uterine artery embolization (UAE) to determine the percentage of infarction of leiomyoma tissue (complete = 100%, almost complete = 90%-99%, and partial = 0%-89%).

Decreased bilateral cortical representation patterns in writer's cramp: a functional magnetic resonance imaging study at 3.0 T.

Functional magnetic resonance imaging was used to characterize patterns of cortical activation in response to sensory and motor tasks in patients with writer's cramp. 17 patients and 17 healthy subjects were examined during finger-tapping, index finger flexion, and electrical median nerve stimulation of both hands during electromyographic monitoring. SPM2 was used to evaluate Brodmann area (BA) 4, 1, 2, 3, 6, 40.

Impact of image noise levels, scout scan dose and lens shield on image quality and radiation exposure in z-axis dose-modulated neck MSCT on 16- and 64-slice Toshiba Aquilion scanners.

Objective: Assessing the impact of image noise (IN) levels, scout scan dose and lens shield use on image quality and radiation exposure in neck multislice CT (MSCT) when using z-axis dose modulation (DM).

Methods: Neck MSCT phantom studies with/without z-axis DM were performed by using different IN levels (S.D.

Uterine artery embolization in patients with symptomatic diffuse leiomyomatosis of the uterus.

Six patients with symptomatic diffuse uterine leiomyomatosis underwent technically successful uterine artery embolization. After a median follow-up of 16 months, five women presented with permanent alleviation of symptoms and a normalized quality of life according to the Uterine Fibroid Symptom and Quality of Life questionnaire. Magnetic resonance imaging showed impressive recovery of the myometrium, and the infarcted leiomyomas shrank and were partially expelled.

Acrylamido polyvinyl alcohol microspheres for uterine artery embolization: 12-month clinical and MR imaging results.

Purpose: To report the 12-month clinical and magnetic resonance (MR) imaging results of an ongoing two-center registry involving acrylamido polyvinyl alcohol (PVA) microspheres for uterine artery embolization (UAE) for leiomyomas.

Materials And Methods: A total of 69 patients underwent UAE with 500-700-microm, 700-900-microm, and 900-1,200-mum acrylamido PVA microspheres (BeadBlock). Thirty-three patients underwent UAE with a limited embolization (protocol A) and 36 patients underwent UAE with stasis as the angiographic endpoint (protocol B).

Uterine fibroids: contrast-enhanced MR angiography to predict ovarian artery supply--initial experience.

Purpose: To prospectively evaluate the diagnostic performance of contrast material-enhanced magnetic resonance (MR) angiography in helping predict ovarian artery supply of uterine fibroids by using postembolization conventional aortography as the reference standard.

Materials And Methods: The protocol for the study was approved by the institutional review board, and each patient gave informed consent. Ninety consecutive women (mean age, 42.
