Prostate gland motion assessed with cine-magnetic resonance imaging (cine-MRI)

International Journal of Radiation Oncology*Biology*Physics, 2005
To quantify prostate motion during a radiation therapy treatment using cine-magnetic resonance imaging (cine-MRI) for time frames comparable to that expected in an image-guided radiation therapy treatment session (20-30 min).Six patients undergoing radiation therapy for prostate cancer were imaged on 3 days, over the course of therapy (Weeks 1, 3, and ...

Automatic Contour Propagation in Cine Cardiac Magnetic Resonance Images

IEEE Transactions on Medical Imaging, 2006
We have developed a method for automatic contour propagation in cine cardiac magnetic resonance images. The method consists of a new active contour model that tries to maintain a constant contour environment by matching gray values in profiles perpendicular to the contour.

Demonstration of aortic lesions via cine magnetic resonance imaging

Magnetic Resonance Imaging, 1990
Cine-MRI was used to evaluate eight patients with known thoracic aorta disease. Included in this study were three aortic coarctations, two aortic dissections, an aneurysm, a posttraumatic pseudoaneurysm, and a patent ductus arteriosus. Cine-MRI was found to be valuable in the assessment of the pathologic anatomy and associated flow disturbances in ...

Cine Magnetic Resonance Imaging of Spinal Intradural Arachnoid Cysts

Neurosurgery, 1997
The diagnostic value of cine magnetic resonance imaging (CMRI) that visualizes fluid and tissue movement was evaluated in patients with spinal intradural arachnoid cysts, a rare but increasingly detected cause of spinal cord dysfunction.Four patients with thoracic spinal intradural arachnoid cysts were investigated with conventional T1- and T2-weighted

Evaluation of mitral stenosis by cine magnetic resonance imaging

American Heart Journal, 1992
To evaluate the ability of cine magnetic resonance imaging (cine MRI) in the assessment of mitral stenosis (MS), we studied 20 patients (14 women and 6 men, mean age 60.6 +/- 8.5 years) with rheumatic mitral valve stenosis by using an 0.5 T magnet. Cine MRI showed several signs of MS.

Uterine Contractility Evaluated on Cine Magnetic Resonance Imaging

Annals of the New York Academy of Sciences, 2007
Abstract:  The inherent contractility of the uterus has attracted concern of researchers and exhibits two known patterns of contraction. One is focal and sporadic bulging of the myometrium, and the other is rhythmic and subtle stripping movement in the subendometrial myometrium, known as uterine peristalsis.

Cardiac motion analysis from magnetic resonance imaging: Cine magnetic resonance versus tagged magnetic resonance

2007 Computers in Cardiology, 2007
The objective of this work is to compare the results obtained from the motion analysis of tagged vs. CINE MR sequences when using spatio-temporal non-rigid registration techniques based on pixel intensity. Those techniques have been previously validated on tagged MR images.

Left Ventricular Pseudoaneurysm: Diagnosis by Cine Magnetic Resonance Imaging

Cardiology, 1999
We report a case that illustrates the difficulty in diagnosing left ventricular (LV) pseudoaneurysm and the potential value of cine magnetic resonance imaging (MRI). A 69-year-old man with a history of ischemic congestive heart failure had a mass found on routine chest X-ray, contiguous with the cardiac silhouette.

Functional cine magnetic resonance imaging in women after abdominal sacrocolpopexy

Obstetrics & Gynecology, 2001
To evaluate whether functional cine magnetic resonance imaging (MRI) is a reliable method for verifying postoperative anatomy and function in women after abdominal sacrocolpopexy.We did postoperative functional cine MRI in 25 women who had sacrocolpopexies.

Phase contrast cine magnetic resonance imaging.

Magnetic resonance quarterly, 1992
Phase contrast cine magnetic resonance imaging (MRI) combines the flow-dependent contrast of phase contrast MRI with the ability of cardiac cine imaging to produce images throughout the cardiac cycle. Two pulse sequence types are used for sensitivity to flow in one direction, whereas four are needed for sensitivity in all directions.
