Advanced MRI helps unravel mysteries of babies' brains
By Jon Cartwright
Some 85 billion neurons and upwards of 100 trillion connections -- the adult human brain is the most complex object in the known universe. But how does such a rich neural network grow from a tiny fetus? And how does that growth affect the way our brains ultimately function?

New methods can help tackle growth of pseudoaneurysms
By Philip Ward
Prompt diagnosis of pseudoaneurysms is essential because the unpredictable associated complications carry high morbidity and mortality rates, and a proper knowledge of embolization materials and percutaneous techniques is vital, an award-winning research team from Spain has found.

Study links gadolinium MR contrast to brain abnormalities
By Wayne Forrest
Japanese researchers have found a connection between gadolinium-based MRI contrast and abnormalities in two regions of the brain, which could represent a reaction to gadolinium's toxicity, according to a study published on 17 December in Radiology.

7T MRA delves deeper into intracranial aneurysms
By Wayne Forrest
CHICAGO - If and when it is ready for routine clinical use, 7-tesla time-of-flight MR angiography (MRA) will provide "superior assessment" of aneurysms and related vessel features, according to a study presented at RSNA 2013.

Superresolution ultrasound maps the brain
By Jon Cartwright
Researchers have overcome an inability of ultrasound to map capillaries and other vessels in the brain by injecting micrometer-sized bubbles into the bloodstream. Although the technique has been demonstrated only on a model brain so far, it's a promising new way to map the brain's vascular networks.

MRA helps detect risk from unruptured cerebral aneurysms
By Wayne Forrest
MR angiography (MRA) using a 3D time-of-flight sequence could well be the most efficient technique for detecting unruptured cerebral aneurysms and determining if they pose a health risk, according to a study published in the October 15 issue of Annals of Internal Medicine.

Lancet: Angiography busts theory of venous link to MS
By Eric Barnes
Countering prior findings that cerebrospinal venous narrowing and multiple sclerosis (MS) go hand in hand, a study incorporating both x-ray venography and ultrasound found that venous narrowing is unrelated to MS. The new results were published online on 9 October in Lancet.

Brain stones: Between a rock and a hard place?
By Philip Ward
Brain stones -- large solid intracranial calcifications -- are more common than previously thought, and while MRI sequences can be useful adjuncts, CT is now the mainstay in identifying and characterizing these intriguing items, Belgian researchers have asserted.
