To determine the interrelationships between MRI-defined lesion and atrophy measures of spinal cord involvement and brain involvement and their relationships to disability in a small cohort of patients with multiple sclerosis (MS). ⋯ In this preliminary study of mildly disabled, treated MS patients, cervical spinal cord atrophy most strongly correlates with physical disability in MS when accounting for a wide range of other CNS measures of lesions and atrophy, including thoracic or whole spinal cord volume, and cerebral gray, white or whole brain volume. The weak relationship between spinal cord and brain lesions and atrophy may suggest that they progress rather independently in patients with MS.

This study was designed to review the diagnostic performance of myocardial innervation imaging using iodine-123-metaiodobenzylguanidine (MIBG) scintigraphy in differential diagnosis between dementia with Lewy bodies (DLB) and other dementias. ⋯ Myocardial innervation imaging with MIBG scintigraphy demonstrated high pooled sensitivity and specificity in patients with suspected DLB. MIBG scintigraphy is an accurate test for differential diagnosis between DLB and other dementias.

Review
Neuroimaging of pediatric intracranial infection--part 1: techniques and bacterial infections.
Conventional and advanced neuroimaging have become central to the diagnosis of infectious diseases of the pediatric central nervous system. Imaging modalities used by (pediatric) neuroradiologists include cranial ultrasound, computed tomography, and magnetic resonance imaging, including advanced techniques such as diffusion weighted or tensor imaging, perfusion weighted imaging, susceptibility weighted imaging, and (1) H magnetic resonance spectroscopy. In this first of a two part review, imaging techniques in general and the imaging findings of bacterial infections of the intracranial compartment including epidural empyema, subdural empyema, meningitis, cerebritis, cerebral abscess, and pyogenic intraventricular empyema (ventriculitis) are discussed.
