detection of brain tissues using magnetic resonance imaging (mri) is an active and challenging research area in computational neuroscience. brain mri artifacts lead to an uncertainty in pixel values. therefore, brain mri segmentation is a complicated concern which is tackled by a novel data fusion approach. the proposed algorithm has two main steps. in the first step the brain mri is divided to...

UNLABELLED The purpose of this study was to determine whether 201Tl retention in focal intracranial lesions can help distinguish central nervous system (CNS) lymphoma from toxoplasmosis and other nonmalignant CNS lesions in patients with acquired immunodeficiency syndrome. METHODS Forty-nine patients who presented with focal lesions on CT and/or MRI had 201Tl brain SPECT studies (early and de...

OBJECTIVES We studied the effect of drug-eluting stent implantation for chronic total coronary occlusion (CTO) on left ventricular volumes and function and assessed the predictive value of magnetic resonance imaging (MRI) performed before revascularization. BACKGROUND The effect of recanalization of CTO on long-term left ventricular function and the value of myocardial viability assessment wi...

OBJECTIVE To report the feasibility of magnetic resonance imaging (MRI)-guided intervention for diagnosing suspicious breast lesions detectable by MRI only, using the freehand technique with a 3.0-T closed-bore MRI scanner. MATERIALS AND METHODS Five women with 5 consecutive MRI-only breast lesions underwent MRI-guided intervention: 3 underwent MRI-guided needle localization and 2, MRI-guided...

background: to retrospectively describe imaging characteristics of liver metastases on fused fdg-pet/ mri data sets and to compare the diagnostic accuracy of mri and fused fdg-pet/mri data sets for the detection of liver metastases in patients undergoing systemic anticancer treatment. materials and methods: 43 oncological patients (mean age: 56+/- 11 years) were investigated by fdg-pet/ct and l...

PURPOSE Vascular disrupting agents are anticancer agents that typically produce a cytostatic tumor response. Vessel size index magnetic resonance imaging (MRI) allows for the estimation of the fractional blood volume (fBV) and blood vessel size (Rv). We assessed whether the vessel size index parameters provided imaging biomarkers for detecting early tumor response to a vascular disrupting agent...

BACKGROUND AND PURPOSE Pyramidal tract Wallerian degeneration has been detected on magnetic resonance imaging (MRI) as T2-weighted high-intensity areas. We analyzed the relation between the extent of brain stem Wallerian degeneration and activities of daily living (ADL) after supratentorial hemorrhagic stroke. METHODS Twenty-six patients with supratentorial hemorrhage were examined on the cor...
