An especially important issue during these uncertain times, this collection of articles examines Neuroimaging from an economic perspective, with articles that discuss leadership, “turf battles , strategic planning in the face of declining reimbursement, and the impact of teleradiology and telemedicine in cutting costs and improving access. Medicolegal issues are addressed, as is evidence-based medicine and effective utilization. Performance measures and conflict of interest are reviewed, among many other topics.

Information for neuroimaging specialists includes a "Diagnostic Checklist or “Clinical Recommendations along with tables presenting recommended MR sequences and protocols. The primary focus of the issue is 3.0T; one article specifically deals with 7T and higher fields are mentioned sporadically throughout. Topics include: Tumor High-Field MR; Stroke High-Field MR; High-Field MR of Inflammation; Vascular Disorders: MR Angiography of Brain Vessels, MR Angiography of Neck Vessels, and Perfusion Imaging; Plaque Imaging; Neurodegenerative Disease; Epilepsy Imaging; Head and Neck Oncology Applications; Pediatric High-Field Imaging; Spine High-Field Imaging; Ultra High-Field Imaging; Future Perspectives on High-Field MR

Dementia is a massive and increasing global problem, with the current prevalence anticipated to double every 20 years as people live longer. Neuroimaging in dementia is recommended by most clinical guidelines and its role has traditionally been to exclude a mass lesion, rather than to support a specific diagnosis. All radiologists will be aware of a steady rise in the number of requests for brain imaging in old people, but what can imaging reliably tell us and what kind of imaging should we use? In affluent societies we now have a range of structural and molecular brain imaging techniques at our disposal, with specific ligands and sophisticated image analysis techniques now available for clinical use. However, we have difficulty justifying which patients to scan, using which modality and when. We know that Alzheimer’s disease is the most common neuropathology contributing to a diagnosis of Alzheimer’s disease but we also know from large post-mortem studies that most brain pathology in those who have died with a diagnosis of dementia is mixed. Thus understanding different diseases that can cause dementia, how these co-exist or interact and appreciating that not all dementia is Alzheimer’s disease is important. Equally important is awareness of individual differences in response to a neuropathological burden and what factors provide resilience against dementia that might be maximized to reduce or postpone its impact. This issue draws together contributions from experts in their fields to provide clarity to the topic in a comprehensive collection of articles.
