Quantification of Esophageal Tumor Motion on Cine-Magnetic Resonance Imaging [PDF]

International Journal of Radiation Oncology*Biology*Physics, 2014
To quantify the movement of esophageal tumors noninvasively on cine-magnetic resonance imaging (MRI) by use of a semiautomatic method to visualize tumor movement directly throughout multiple breathing cycles.Thirty-six patients with esophageal tumors underwent MRI. Tumors were located in the upper (8), middle (7), and lower (21) esophagus.

Super‐Resolution Cine Image Enhancement for Fetal Cardiac Magnetic Resonance Imaging [PDF]

Journal of Magnetic Resonance Imaging, 2021
BackgroundFetal cardiac magnetic resonance imaging (MRI) improves the diagnosis of congenital heart defects, but is sensitive to fetal motion due to long image acquisition time. This may be overcome with faster image acquisition with low resolution, followed by image enhancement to provide clinically useful images.PurposeTo combine phase‐encoding ...

Cardiovascular magnetic resonance at 3.0T: Current state of the art

Journal of Cardiovascular Magnetic Resonance, 2010
There are advantages to conducting cardiovascular magnetic resonance (CMR) studies at a field strength of 3.0 Telsa, including the increase in bulk magnetization, the increase in frequency separation of off-resonance spins, and the increase in T1 of many

Magnetic resonance (MR) cine imaging of the human heart

The British Journal of Radiology, 1985
Abstract A novel approach has been developed for MR cine imaging of the human heart by a modified ECG-gated 2DFT method. A pulse sequence has been devised to minimise the effects of saturation which can be anticipated in sequences that require rapid pulsing. Five frames are produced at the same anatomical level at predetermined intervals
