Through a survey sent to 186 academic departments of radiology, the authors sought to determine patterns of spinal pain management injections by neuroradiologists. Twenty-one percent of surveys were completed showing that over 50% of departments were involved in this type of procedure with the number of procedures remaining stable during the past 5 years in most locations. The majority of referrals came from orthopedic surgeons, neurosurgeons, and neurologists. The most common procedures were epidural steroid injections, nerve root blocks, facet injections, and synovial cyst aspirations. Most fellows and more than 50% of residents were considered to have achieved proficiency in these procedures during their training.

These authors investigated the effect of perfusion deficits on patients with MS with cognitive impairment. In 45 patients with secondary-progressive MS, cognition was assessed using standardized clinical tests and CBF and CBV perfusion maps were obtained, analyzed, and correlated with gray and white matter and lesion volumes. Perfusion in the deep gray matter nuclei and frontal cortex was significantly reduced in cognitively impaired patients with MS despite no significant differences regarding gray matter, white matter, and lesion volumes. Of the cognitive parameters investigated, information processing speed was most affected.
