Diffusion Tensor Magnetic Resonance Imaging (DTMRI) technique enables the measurement of diffusion parameters and therefore, informs on the structure of the biological tissue. This technique is applied with success to the static organs such as brain. However, the diffusion measurement on the dynamically deformable organs such as the in-vivo heart is a complex problem that has however a great po...

Magnetic Resonance-guided High-Intensity Focused Ultrasound (MR-HIFU) is a noninvasive technique for ablation therapy for uterine myomas, where focused ultrasound energy beam generates localized high temperature in the selected area and coagulates chosen tissue, leaving the skin and tissues in between unharmed. Magnetic resonance imaging enables accurate targeting for HIFU as well as temperatur...

U nderstanding human speech production is of great interest from engineering, linguistic, and several other research points of view. While several types of data available to speech understanding studies lead to different avenues for research, in this article we focus on real-time (RT) magnetic resonance imaging (MRI) as an emerging technique for studying speech production. We discuss the detail...

Background Dyspnea with exertion is a common symptom in patients with left ventricular (LV) systolic and diastolic dysfunction. Assessing changes in systolic and diastolic hemodynamic parameters with exercise is necessary to thoroughly characterize these patients. Evaluation of changes in LV systolic function with exercise stress cardiac magnetic resonance (MR) has been demonstrated previously ...

This paper presents a magnetic resonance imaging (MRI)-based virtual cystoscopy system, which extracts the bladder wall from T1-weighted MR images where the wall is enhanced while the urine and surrounding fat tissues are suppressed by a fully non-invasive imaging procedure. The system analyzes the extracted wall and detects abnormal features automatically. Test results are encouraging by FROC ...

Magnetic Resonance Imaging in Epidemic Adenoviral Keratoconjunctivitis Most clinicianswould agree that there is no reason to obtain a magnetic resonance (MR) scan to evaluate a patient with viral conjunctivitis.Wescheduledapatient foranannualMRscan to monitor his optic nerve meningiomas. By coincidence, he had florid viral conjunctivitis the day the scan was performed. It showed severe eyelid e...
