Measurement of Cardiac Chamber Volumes by Cine Magnetic Resonance Imaging

Angiology, 1993
Cardiac chamber volumes (both atria and ventricles) in 19 healthy volun teers were measured noninvasively by cine magnetic resonance imaging (MRI). First, cardiac localization was determined from the coronal image by 0.5-T superconducting magnetic imager.

Cine Magnetic Resonance Imaging: Tomographic Analysis of Left Ventricular Function

Cardiology Clinics, 1989
Cine magnetic resonance imaging has the attributes that enable its use as a method for quantitating the three-dimensional functional geometry of the ventricles. The completely noninvasive nature of this technique is advantageous for sequential studies needed to monitor evolution of cardiac disease and response to therapy.

Quantification of cardiac function by conventional and cine magnetic resonance imaging

Cardiovascular and Interventional Radiology, 1987
Magnetic resonance imaging (MRI) has been effective for depicting cardiac anatomy and is already established as a technique for the evaluation of some structural abnormalities of the heart and pericardium. With recent advances, MRI can now be used to quantitate cardiac function.

Three-Dimensional Motion of Liver Tumors Using Cine-Magnetic Resonance Imaging

International Journal of Radiation Oncology*Biology*Physics, 2008
To measure the three-dimensional motion of liver tumors using cine-magnetic resonance imaging (MRI) and compare it to the liver motion assessed using fluoroscopy.Liver and liver tumor motion were investigated in the first 36 patients with primary (n = 20) and metastatic (n = 16) liver cancer accrued to our Phase I stereotactic radiotherapy study.

3D fusion of cine and late-enhanced cardiac magnetic resonance images

2012 9th IEEE International Symposium on Biomedical Imaging (ISBI), 2012
A procedure to fuse the information of short-axis cine and late enhanced magnetic resonance images is presented. First a coherent 3D reconstruction of the images is obtained by object-based interpolation of the information of contiguous slices in stacked short-axis cine acquisitions and by the correction of slice misalignments with the aid of a set of ...

Cerebral dissection from syringomyelia demonstrated using cine magnetic resonance imaging

Journal of Neurosurgery, 2001
✓ A 16-year-old boy presented at the authors' emergency department with a sudden deterioration of respiration. He had been paraparetic for 3 years and had become quadriplegic 2 days previously. Magnetic resonance images revealed a Chiari I malformation and a hydromyelic cavity extending from C-1 to T-11.

Correction of motion artifacts from cardiac cine magnetic resonance images.

Academic radiology, 2005
An image registration method was developed to automatically correct motion artifacts, mostly from breathing, from cardiac cine magnetic resonance (MR) images.The location of each slice in an image stack was optimized by maximizing a similarity measure of the slice with another image slice stack. The optimization was performed iteratively and both image

Uterine peristalsis of adenomyosis patients on cine magnetic resonance imaging

International Journal of Gynecology & Obstetrics
AbstractObjectiveAdenomyosis, a common gynecologic disease, can cause infertility. Uterine peristalsis (UP) is a wave‐like contraction. Abnormal UP has been linked to infertility. The aim of this study using magnetic resonance imaging (MRI) was to compare UP between uterine walls with adenomyosis and normal walls to ascertain the possible effects of ...

Cine magnetic resonance imaging of the subcoracoid region.

Orthopedics, 1998
Cine magnetic resonance imaging (MRI) was used to define the normal space between the humeral head and coracoid process, known as the subcoracoid space, to quantify the subcoracoid space in symptomatic patients and identify the anatomic structures responsible for narrowing of this space. The study population was comprised of 50 normal volunteers and 75
