Automated pattern recognition techniques are needed to help radiologists categorize MRS data of brain tumors according to histological type and grade. A major question is whether a computer program "trained" on spectra from one hospital will be able to classify those from another, particularly if the acquisition protocol is different. A subset of 144(More)
STUDY OBJECTIVES Rapid-eye-movement (REM) sleep behavior disorder (RBD) is thought to result from a dysfunction of the brainstem structures that regulate physiologic REM sleep muscle atonia. Proton magnetic resonance spectroscopy (1H-MRS) is a noninvasive method that allows detection of in vivo neuronal dysfunction in localized brain areas. The aim of our(More)
The Fatigue Impact Scale for Daily Use (D-FIS) was used in a cross-sectional study including 142 consecutive Parkinson’s disease (PD) patients. Usual clinical measures for PD, the Montgomery-Asberg Depression Rating Scale and the Parkinson’s Disease Questionnaire-8 items were applied. In addition to the D-FIS, patients with fatigue (67.6%, PWF) completed(More)
PURPOSE To retrospectively assess the value of endorectal magnetic resonance (MR) imaging and MR spectroscopy combined with the free-to-total prostate-specific antigen (PSA) ratio for detecting prostate cancer in men with elevated PSA levels. MATERIALS AND METHODS The institutional review board approved the study, and all patients provided informed(More)
Delayed acquisition of developmental motor and cognitive milestones is a common clinical expression of many etiological processes. Imaging exams of developmentally delayed children often show no structural brain alterations despite suspicion of brain maturation delay. MRI studies increasingly suggest that white matter myelination finely reflects the(More)
PURPOSE To obtain an accurate CAD/CAM metal framework over 6 implants using a Chairside Intraoral Scanner based on the principle of active (optical) wavefront sampling. MATERIAL AND METHODS Six prototype cylindrical scan bodies screwed in the implants were used to obtain an intraoral digital impression. A conventional resin tooth try-in was fabricated and(More)
BACKGROUND The aim of this study was to characterize the muscular reservoirs of phosphorilated energetic components of athletes using 31P-MRS. METHODS The sample was formed by 14 elite athletes from the Center for High Sportive Performance (CAR, Sant Cugat del Vallés, Spain). The pattern of the phosphorilated metabolites was measured from the muscle(More)

Material & methods: This is a 81 years old lady with hypothyroidism who was operated 3 years ago. In the previous surgery an onlay mesh placement was performed. The patient developed a symptomatic recurrent incisional hernia that impaired her quality of life. The patient was operated under general anesthesia. A Rives procedure was planned. The main goals of(More)
