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.

Traumatic head/brain injury (TBI) is a leading cause of death and life-long disability in children. The biomechanical properties of the child's brain and skull, the size of the child, the age-specific activity pattern, and higher degree of brain plasticity result in a unique distribution, degree, and quality of TBI compared to adult TBI. A detailed knowledge about the various types of primary and secondary pediatric head injuries is essential to better identify and understand pediatric TBI. The goals of this review article are (1) to discuss the unique epidemiology, mechanisms, and characteristics of TBI in children, and (2) to review the anatomical and functional imaging techniques that can be used to study common and rare pediatric traumatic brain injuries and their complications.

In the second half of this 2-part review, the neuroimaging features of the most common viral, fungal, and parasitic infections of the pediatric central nervous system are discussed. Brief discussions of epidemiology and pathophysiology will be followed by a review of the imaging findings and potential differential considerations.

Ascent™: a novel balloon microcatheter device used as the primary coiling microcatheter of a basilar tip aneurysm.
Intracranial aneurysms undergoing balloon-assisted endovascular repair are particularly challenging given the concurrent use of one or more catheters in addition to the primary coiling microcatheter. Here, we describe a previously unreported novel device where a balloon catheter was used as the primary coiling microcatheter, thereby eliminated the need for additional catheters.
