MR imaging throws light on causes of epilepsyAn epileptic seizure is the external manifestation of a functional cerebral disorder that can affect 10% of the world's population. Virtually any brain abnormality can irritate vulnerable neurons and produce epileptic seizures. The nature and characteristics of the seizure depend on the part of the brain involved in the disturbance.

Percutaneous ablation treats bone tumors safely, effectivelyAblation techniques have rapidly evolved and have been proved effective for treatment of benign skeletal lesions and, more recently, for palliation of painful metastatic skeletal disease. Treatment of primary bone lesions is largely restricted to benign lesions, such as osteoid osteomas, as a single-modality treatment or as an adjunct to surgical resection.1-4 The use of ablation techniques for treatment of metastatic disease has developed because of the often disabling pain cancer patients experience. This pain can persist despite use of conventional therapies, including external-beam radiation and opioid analgesics.5-8

MR finds widespread clinical use in MS diagnosis, managementMR imaging has provided important insights into the pathophysiology of multiple sclerosis.1 Conventional MR scans afford only gross estimates of the extent and nature of tissue damage associated with MS,2 however, and the data correlate poorly with measures of concurrent disability in patients. Advances in MRI technology have improved the correlation of its findings with clinical status and increased the utility of MRI data as surrogate markers in monitoring disease progression and response to therapy.3 Newer techniques, such as magnetization transfer (MT), diffusion-weighted, and functional MRI, as well as proton MR spectroscopy and measures of brain and spinal cord atrophy, may help further elucidate MS pathology2 and provide opportunities for new treatment approaches.4
