Dynamic Metaheuristics for Brain Cine-MRI

2017
Recently, a new technique for obtaining brain images of cine-MR (Magnetic Resonance) type has been developed by Hodel et al., (Brain ventricular wall movement assessed by a gated cine MR true FISP sequence in patients treated with endoscopic third ventriculostomy 19(12), (2009), [8]).

Trajectory correction for free-breathing radial cine MRI

Magnetic Resonance Imaging, 2014
Radial acquisitions can suffer from trajectory errors leading to reduced image quality. Here we present a new method of trajectory correction that uses all spokes of a radial acquisition and compare it to an existing method that uses a two-spoke pre-scan calibration. For both methods, estimates of the necessary shifts were made using magnitude or phase

Cine-MRI-Aided Endomyocardectomy in Idiopathic Hypereosinophilic Syndrome

The Annals of Thoracic Surgery, 1996
The idiopathic hypereosinophilic syndrome is a leukoproliferative disorder marked by a predilection to damage specific organs, including the heart. This report describes a patient with extensive endocardial fibrosis accompanying this syndrome. Right ventricular endomyocardectomy with preservation of the tricuspid valve was performed.

MRI of pseudocoarctation of the aorta: Morphological and cine-MRI findings

Computerized Medical Imaging and Graphics, 1995
We report a case of pseudocoarctation of the thoracic aorta diagnosed by magnetic resonance imaging. Morphological spin-echo findings and cine-MRI performed by gradient-echo multiphase images are reported. No other more invasive examinations were needed to establish the diagnosis of pseudocoarctation and to differentiate from other aortic abnormalities.

Left Ventricular Strain Analysis from Cine MRI

2009 2nd International Conference on Biomedical Engineering and Informatics, 2009
In this paper, based on the ideas of image texture analysis and motion tracking, we present a new method for left ventricular (LV) strain analysis from cine magnetic resonance images(MRI). First, the marking points are extracted with the Harris corner detector on or close to the endocardium and epicardium.

Intramyocardial strain estimation from cardiac cine MRI

International Journal of Computer Assisted Radiology and Surgery, 2014
Functional strain is one of the important clinical indicators for the quantification of heart performance and the early detection of cardiovascular diseases, and functional strain parameters are used to aid therapeutic decisions and follow-up evaluations after cardiac surgery.

Cine-MRI swallowing evaluation after tongue reconstruction

European Journal of Radiology, 2010
To determine the feasibility of cine-MRI for non-invasive swallowing evaluation after surgery for lingual carcinoma with reconstruction using microvascular free flaps.Ten patients with stage IV carcinoma of the mobile tongue and/or tongue base treated by surgical resection and reconstruction with a free flap were evaluated after an average of 4.3 years

Synergy of MDCT and Cine MRI for the Evaluation of Cardiac Motility

American Journal of Roentgenology, 2006
The objective of our study was to validate the feasibility of the synergistic use of cardiac MR and CT data sets for ventricular motility analysis and to correlate measurement variability with underlying heart rate.Twenty patients underwent concurrent ECG-gated MDCT and MRI for evaluation of ventricular motility, expressed as ventricular wall ...

Sonic DL Cardiac Cine MRI at 3T: Comparison with Conventional Segmented Cine MRI

ISMRM Annual Meeting
Motivation: This study aimed to explore the feasibility and accuracy of Sonic DL cardiac magnetic resonance cine technology. Goal(s): We aimed to assess the performance of Sonic DL cine MRI at 3T for left ventricular (LV) volume and mass measurement, especially patients with arrhythmia and/or difficulty in breath-holding.
