Neurosurgery gets boost from 3D-printed head model
By Abraham Kim
An Australian team has devised a 3D-printed head model that enables the realistic simulation of neurosurgical procedures. The technique is based on a combination of MRI and CT angiography scans, and it is described in an online report posted on 1 August by 3D Printing in Medicine.

Holographic lenses focus ultrasound for brain imaging
By Olivia Voyce
Better brain imaging, or even drug delivery, may be feasible due to the pioneering work of Spanish researchers. They have developed a technique for 3D printing holographic lenses that focus ultrasonic sound waves in the brain.

Forsting: Brain imaging for metastasis is not easy
By Frances Rylands-Monk
Radiologists must beware of normal brain images in cancer patients with neurological symptoms and adopt more sensitive techniques to catch brain metastasis. That's the view of Prof. Michael Forsting, who will deliver a keynote lecture on this topic today at the 100th German Radiology Congress (RöKo 2019), to be held from 29 May to 1 June in Leipzig.

Dutch reveal how obesity can influence brain volume
By Wayne Forrest
Dutch researchers investigating obesity have used MRI to link greater levels of body fat to changes in the brain's form and structure, particularly with smaller volumes of gray matter. Their study was published online on 23 April in Radiology.

AI can segment white-matter hyperintensities on MRI
By Erik L. Ridley
Artificial intelligence (AI) algorithms are capable of segmenting cerebral white-matter hyperintensities of presumed vascular origin on brain MR images as well as or better than human observers, enabling more reliable quantification of these lesions, according to the results of a recent AI developer challenge.
