Cine MRI: a new approach to the diagnosis of scapholunate dissociation

Skeletal Radiology, 2015
To evaluate the feasibility of cine MRI for the detection of scapholunate dissociation (SLD) and to compare the sensitivity and specificity of cine MRI with those of cineradiography and arthroscopy.To evaluate feasibility, healthy subjects underwent cine MRI of the wrist.

Evaluation of the Pulmonary Artery by Cine MRI

Journal of Computer Assisted Tomography, 1992
Twenty-four patients whose mediastinal (12 patients) and lung (12 patients) neoplasms were eventually verified were evaluated with cine MRI in addition to conventional methods (plain radiography, CT, MRI, and endoscopy). Using a 1.0 T system and gradient echo (FLASH repetition time 250-350 ms, echo time 12, flip angle 25-60 degrees) multislice pulse ...

High Resolution Cine MRI of Vessel Distension

Journal of Computer Assisted Tomography, 1994
We have evaluated the ability of high resolution cine MRI to quantify vessel distension.Gradient echo imaging was used to acquire high resolution, cardiac-triggered imaging of the ascending aorta in normal volunteers to measure changes in the cross-sectional area of the lumen over the cardiac cycle.

Implementation of compressive sensing for preclinical cine-MRI

SPIE Proceedings, 2014
This paper presents a practical implementation of Compressive Sensing (CS) for a preclinical MRI machine to acquire randomly undersampled k-space data in cardiac function imaging applications. First, random undersampling masks were generated based on Gaussian, Cauchy, wrapped Cauchy and von Mises probability distribution functions by the inverse ...

Cardiac Cine-MRI/CT Registration for Interventions Planning

2019 IEEE 16th International Symposium on Biomedical Imaging (ISBI 2019), 2019
Patient specific multimodal models have proved their impacts on various cardiac clinical procedures. Computed tomography (CT) and magnetic resonance images (MRI) are two modalities widely used in clinical routine to describe anatomy, tissues and cardiac function of patients.

Combination of temporal and spatial denoising methods for cine MRI

2021 IEEE 3rd Global Conference on Life Sciences and Technologies (LifeTech), 2021
In this paper, we propose a denoising method for cine MRI acquired by MoPS. The MoPS-based cine MRI has a high FPS but contains reconstruction noise. DISPEL, a conventional method, performs denoising in the temporal domain. A neural network is further introduced to remove spatial noise. Different from most those methods requiring noisy and clean images,

Cine-MRI of Deglutition: A Systematic Review

Dysphagia
Videofluoroscopy, recognized as the gold standard for dysphagia exploration, has inherent limitations, including poor soft tissue discrimination, radiation exposure, and aspiration risk. In response to these challenges, cine-MRI of swallowing has evolved over the past three decades, yielding diverse methodologies and results across various studies.This

Stress Cine MRI

2008
Cardiovascular magnetic resonance (CMR) imaging is increasingly used to detect the presence of coronary artery disease (CAD) and to assess its hemodynamic significance (1). The development of rapid gradient systems and consequently very short measurement times allows us to perform high-resolution cine imaging of the heart at rest and under stress ...

Out-of-Plane Motion Compensation in Cine-MRI

2012
Significant socio-economic burden of colonic motility disorders necessitates in-depth analysis of this pathology. Current analysis techniques are based on diameter measurements of colonic lumen on cine-MR images. Interleaved multi-plane acquisition makes it difficult to perform simultaneous measurements on the line of plane intersections due to the out-

Tracking diaphragm and chest wall movement on cine-MRI

2018 IEEE 15th International Symposium on Biomedical Imaging (ISBI 2018), 2018
Congenital muscular dystrophies (CMD) are amongst the most common early onset neuromuscular disorder that results in progressive weakness of skeletal, and respiratory muscles. Current methods based on breathing tests are not able to accurately characterize the respiratory muscle involvement.
