susceptibility-weighted imaging (swi) has continued to develop into a powerful clinical tool to visualize venous structures and iron in the brain and to study diverse pathologic conditions. it is a new art which evaluates and exploits the properties of blood, iron and other tissues. it is a magnitude or filtered phase images or combination of both, obtained with high-resolution 3d fully velocit...

We report magnetic resonance (MR) imaging findings including diffusion-weighted imaging and proton MR spectroscopy findings in a patient with infantile Refsum disease. The initial diagnosis was made on the basis of history, clinical findings and biochemical studies. Bilateral and symmetrical involvement of the peritrigonal white matter, centrum semiovale, thalami, corpus callosum and corticospi...

Central nervous system aspergillosis has increased dramatically in recent years. Most of the cases are immunocompromised patients infected from a primary site, usually the lungs or paranasal sinuses, and the organism may spread to the central nervous system. Different neuroimaging patterns that have been reported vary depending on the immunological status of the patients and on the age of the l...

Dear Sir A 58-year-old female had symmetric spasticity, hyperreflexia, extensor plantar responses, spastic dysarthria, and pseudobulbar symptoms. The upper motor neuron involvement had progressed gradually over more than five years, leading to weakness in all four limbs and pseudobulbar symptoms, requiring a percutaneous endoscopic gastrostomy. Denervation potentials were not detectable on need...

Sporadic Creutzfeldt-Jacob disease (CJD) is a rare fatal neurodegenerative prion disease. Clinical fi ndings of CJD consist of a rapid onset dementia, myoclonus, and neurologic disorders. Defi nitive diagnosis is established with histopathologic confi rmation of brain parenchyma or autopsy materials. Periodic triphasic electroencephalography (EEG) changes and detection of 14-3-3 protein in cere...

The cerebellum plays a key role in movement control and in cognition and cerebellar involvement is described in several neurodegenerative diseases. While conventional magnetic resonance imaging (MRI) is widely used for brain and cerebellar morphologic evaluation, advanced MRI techniques allow the investigation of cerebellar microstructural and functional characteristics. Volumetry, voxel-based ...

Introduction Digital dental radiography was introduced in 1987, and many thought this technology would quickly take over as the standard in dental radiology. However, this has not been the case as only 7% to 8% of dental professionals currently use digital imaging systems (1). Many dentists have been resistant to change as the diagnostic quality of digital radiography has been questionable when...

Background Whole body magnetic resonance (MR) imaging is increasingly used as an alternative for conventional autopsy; however, a recent systematic review suggested that post-mortem MR imaging had a sensitivity of 12% (95% CI-0.4 to 31) for detecting major cardiac pathology (Thayyil et al. Eur J Radiol 2010; 75(1):e142-8). We wanted to compare the accuracy of high-resolution 3D post-mortem card...
