BACKGROUND Left ventricular ejection fraction is a powerful independent predictor of survival in cardiac patients, especially those with coronary artery disease. Delayed-enhancement magnetic resonance imaging (DE-MRI) can accurately identify irreversible myocardial injury with high spatial and contrast resolution. To date, relatively limited data are available on the prognostic value of DE-MRI,...

Preterm birth disrupts and alters the complex developmental processes in the cerebral cortex. This disruption may be a contributing factor to widespread delay and cognitive difficulties in the preterm population. Diffusion-weighted magnetic resonance imaging (DW MRI) is a noninvasive imaging technique that makes inferences about cellular structures, at scales smaller than the imaging resolution...

To examine the geometrical parameters of tongue in obstructive sleep apnoea (OSA) based on sex, age and BMI ultrasound (US) MRI. The presence OSA tongue-based obstruction can be predicted using these parameters. Of 100 patients, 64% were diagnosed with according to overnight polysomnography. MRI US devices used measure location was identified drug-induced endoscopy. Statistical analysis perform...

Objective The aim of this study was to identify the effectiveness and selective applications preoperative magnetic resonance imaging (MRI) by investigating clinicopathologic factors index tumor with or without false lesions on MRI. Summary background data Preoperative MRI is commonly performed in patients newly diagnosed breast cancer, but its clinical significance unclear. Methods A total 103 ...

ÐThis is an elementary research for assigning color values to voxels of multichannel Magnetic Resonance Imaging (MRI) volume data. The MRI volume data sets obtained under different scanning conditions are transformed to the components by independent component analysis (ICA), which enhances physical characteristics of the tissue. The transfer functions for generating color values from independen...

OBJECTIVE To investigate the added diagnostic value of 3.0 Tesla breast MRI over conventional breast imaging in the diagnosis of in situ and invasive breast cancer and to explore the role of routine versus expert reading. MATERIALS AND METHODS We evaluated MRI scans of patients with nonpalpable BI-RADS 3-5 lesions who underwent dynamic contrast-enhanced 3.0 Tesla breast MRI. Initially, MRI sc...

Syndrome of spontaneous cerebrospinal fluid hypovolemia (SCH) is a rare cause of new onset headache. We report six cases of SCH presenting with new onset headache. All six cases were females. Acute onset orthostatic headache and neck pain were the chief characteristics of SCH in our cases. The MRI brain showed pachymeningeal gadolinium enhancement in all patients. Spinal extradural CSF collecti...

Background MRI-derived T1 times are associated with diffuse interstitial myocardial fibrosis. LV diastolic dysfunction and fibrosis are important components of cardiac disease, but their relationship has not been firmly established. Early diastolic strain rate (Epeak) has been validated as an indicator of diastolic function by tagged MRI. We derive a novel strain relaxation index (SRI) based on...

Introduction Using MRI and a contrast agent (CA), one can assess numerous characteristics of the microvasculaure: Blood Volume fraction (BVf), Vessel Size Index (VSI), or local SO2 (lSO2) [1] [2]. These MRI methods rely on infinite cylinders to model the vessels that contain the CA. In the vessel, one assumes that the CA is homogeneously distributed [3]. The contribution of red blood cells is a...

Hybrid or multimodal imaging has provided excellent opportunities to meet the needs inherent in the management of neurodegenerative diseases, especially in Alzheimer Disease context. PET-MRI equipment for simultaneous data acquisition attempts to address this challenge by bridging the limitations of PET-CT at the brain level and improving the results achieved through a simultaneous real-time co...
