Concussions could result in permanent brain impairment

Concussions, whether from an accident, sporting event, or combat, can lead to permanent loss of higher level mental processes. Scientists have debated for centuries whether concussions involve structural damage to brain tissue or whether physiological changes that merely impair the way brain cells function, explain this loss.

New minimally invasive surgery techniques and instruments reduce tissue damage and infection

New, delicate surgery techniques to hunt for tumours could benefit from a lighter touch - but from a robot, rather than from a human hand. Canadian researchers have created a touchy-feely robot that detects tougher tumour tissue in half the time, and with 40% more accuracy than a human. The technique also minimises tissue damage.

Computed tomography angiography can identify abnormalities and injury beyond the pulmonary arteries

Children with clinically suspected pulmonary embolism (PE) are increasingly being evaluated with CT angiography (CTA). Even though many children ultimately test negative for PE, study results suggest that CTA is still valuable for this indication because it has the ability to accurately detect a variety of alternative diagnoses.
