The mucopolysaccharidoses (MPS) represent a group of inheritable, clinically heterogeneous lysosomal storage disorders, in which progressive accumulation of glycosaminoglycans (GAGs) can affect organs and tissues all over the body. The current paper discusses the skeletal X-ray and neuroimaging findings in MPS patients, and the imaging techniques that can(More)
Functional magnetic resonance imaging (fMRI) has surfaced as a powerful method to study brain function in humans. While the involvement of neuroradiologists in fMRI studies in the clinical setting is obvious, in neuroscience research most of the investigators are not specialists trained in reading brain images. Advances in neuroimaging are increasingly(More)
A higher risk of suicidal attempt after subthalamic nucleus deep brain stimulation (STN-DBS) for Parkinson's disease (PD) has been consistently reported. We retrospectively analyzed 3 PD patients with suicide attempts after STN-DBS. All patients had normal pre- and immediate postoperative psychopathological and cognitive evaluations, with STN-DBS yielding a(More)
BACKGROUND AND PURPOSE Poor outcome and rebleeding, after admission to hospital of patients with spontaneous subarachnoid hemorrhage (SAH) has been found to be predicted by loss of consciousness at ictus (LOCi). In this study, we assessed the clinical and neuro-radiological significance of the LOCi in non-traumatic SAH. PATIENTS AND METHODS The authors(More)
Background. Few data have been published regarding long-term mortality in patients with Parkinson's disease treated with DBS. Methods. This study analyzed long-term mortality rates, causes, and correlates in PD patients treated with DBS. Results. 184 consecutive patients were included; mean follow-up was 50 months. Fifteen deaths occurred (total 8.15%,(More)
Parkinson's disease is a progressive degenerative disease of the central nervous system frequently becoming motor disabling. Deep brain stimulation is one more therapeutic option. The authors describe the different steps of this therapeutic procedure with detail on imaging protocol to the precise and exact targeting of subthalamic nucleus. MR and CT imaging(More)

INTRODUCTION With the advent of magnetic resonance imaging (MRI), and in particular in the 1990s with the introduction of functional MRI (fMRI) – a neuroimaging tool that measures hemodynamic responses related to neural activity – much has been done for the protection of the human subject. As imagers, we worry since the early days about magnet safety, and(More)
