UNLABELLED We present software for integrated analysis of brain PET studies and coregistered segmented MRI that couples a module for automated placement of regions of interest (ROI) with 4 alternative methods for partial-volume-effect correction (PVEc). The accuracy and precision of these methods have been measured using 4 simulated (18)F-FDG PET studies(More)
Global grey matter (GM) loss has been reported in multiple sclerosis (MS). We addressed the question of if and where GM loss is localized by means of optimized voxel-based morphometry, applied to MRI studies of 51 patients with clinically defined relapsing-remitting MS and 34 age-matched normal subjects, segmented into normal and abnormal brain tissues(More)
OBJECTIVE To measure white matter (WM) and gray matter (GM) atrophy and lesion load in a large population of patients with multiple sclerosis (MS) using a fully automated, operator-independent, multiparametric segmentation method. METHODS The study population consisted of 597 patients with MS and 104 control subjects. The MRI parameters were abnormal WM(More)
Adult GH deficiency (GHD) is associated with increased cardiovascular morbidity and mortality due to unfavorable lipid profile, hyperfibrinogenemia, and impairment of cardiac performance. This prospective controlled cohort study evaluated the effects of 12-month GH replacement on lipid profile, fibrinogen levels, cardiac mass by echocardiography, and(More)
UNLABELLED New imaging techniques have been introduced to assess the extent and severity of disease in multiple myeloma (MM) patients. The aim of our study was to compare newer imaging modalities-such as (18)F-FDG PET/CT, (99m)Tc-methoxyisobutylisonitrile ((99m)Tc-MIBI) scintigraphy, and MRI-to assess their relative contribution in the evaluation of MM(More)
BACKGROUND Fatigue is a major problem in multiple sclerosis (MS), and its association with MRI features is debated. OBJECTIVE To study the correlation between fatigue and lesion load, white matter (WM), and grey matter (GM), in MS patients independent of disability. METHODS We studied 222 relapsing remitting MS patients with low disability (scores <or=2(More)
The aim of this prospective study was to evaluate the bone mineral density (BMD) at lumbar spine and femoral neck levels and biochemical parameters of bone turnover in 20 consecutive hyperprolactinemic males before and after an 18-month treatment with different dopamine agonists. Six patients received bromocriptine at a dose of 2.5-10 mg/day; 7 patients(More)
Multiple system atrophy can be classified into two main types, a Parkinsonian (MSA-P) and a cerebellar (MSA-C) variant based on clinical presentation. We obtained diffusion-weighted magnetic resonance imaging (DWI) in 9 MSA-P and 12 MSA-C patients and 11 controls, and correlated DWI changes with disease duration and severity. We found that Trace (D) values(More)
A fully automated magnetic resonance (MR) segmentation method for identification and volume measurement of demyelinated white matter has been developed. Spin-echo MR brain scans were performed in 38 patients with multiple sclerosis (MS) and in 46 healthy subjects. Segmentation of normal tissues and white matter lesions (WML) was obtained, based on their(More)
CONTEXT Radioactive iodine is a crucial tool for treatment of differentiated thyroid cancer (DTC). In 5% of cases, DTCs lose I-131 avidity and assume an aggressive behaviour. Treatment options for iodine-refractory DTC are limited. We report the experience of off-label use of the tyrosine kinase inhibitor sorafenib for treatment of advanced(More)
