Time-resolved contrast-enhanced 3D MR angiography.
An MR angiographic technique, referred to as 3D TRICKS (3D time-resolved imaging of contrast kinetics) has been developed. This technique combines and extends to 3D imaging several previously published elements. These elements include an increased sampling rate for lower spatial frequencies, temporal interpolation of k-space views, and zero-filling in the slice-encoding dimension. When appropri...
متن کاملThree-Dimensional Quantitative Assessment of Uterine Fibroid Response after Uterine Artery Embolization Using Contrast-Enhanced MR Imaging.
PURPOSE To evaluate the clinical feasibility and diagnostic accuracy of three-dimensional (3D) quantitative magnetic resonance (MR) imaging for the assessment of total lesion volume (TLV) and enhancing lesion volume (ELV) before and after uterine artery embolization (UAE). MATERIALS AND METHODS This retrospective study included 25 patients with uterine fibroids who underwent UAE and received ...
متن کاملContrast-Enhanced MR Angiography
Magnetic resonance angiography (MRA) is increasingly used to evaluate arterial and venous diseases. Although the resolution of MRA is not as high as that of conventional angiography, it is sufficient to evaluate pathologic conditions in the larger vascular structures of most parts of the body. It is especially useful in patients who cannot tolerate the risks of iodinated contrast agents or arte...
متن کاملCarotid Artery Stenosis: Comparison of 3D Time-of-Flight MR Angiography and Contrast-Enhanced MR Angiography at 3T
Purpose. The aim of this study was to assess the correlation of 3D time-of-flight MR angiography (TOF MRA) and contrast-enhanced MR angiography (CEMRA) for carotid artery stenosis evaluation at 3T. Material and Methods. Twenty-three patients (5 f, 18 m; mean age 61 y, age range 45-78 y) with internal carotid artery stenosis detected with ultrasonography were examined on a 3.0T MR system. The MR...
متن کاملContrast-enhanced MR arteriography to detect ovarian artery supply to uterine fibroids in patients scheduled for uterine artery embolization: Comparison with conventional angiography during uterine artery embolization for fibroids
N. Kashitani, S. M. Ascher, J. B. Spies, P. A. Flick, R. C. Jha radiology, georgetown university, washington, dc, United States BACKGROUNDS/INTRODUCTION: Uterine leiomyoma is the most common benign tumor of the female pelvis and affects 20-50% of women. Since 1995, uterine artery embolization (UAE) has been gaining acceptance as a primary uterine conserving treatment for women with symptomatic ...
