2016 05 Jan

Computed Tomography (CT) ranks as one of the top five medical developments of the last 40 years, with its inventors being awarded the Nobel Prize in Medicine in 1979 (Radiologyinfo. org 2011). From the first generation of CT scanners in the 1970s to the fourth generation scanners of today, the technological improvements of CT in speed, resolution and...Read more

2015 29 Dec

Combinations of history and physical examination features in clinical decision rules can identify patients with minor head trauma at low risk of severe intracranial injuries, and for whom head CT may not be necessary. The findings are based on a systematic review conducted by Joshua S. Easter, MD, MSc, of the Department of Emergency Medicine, University...Read more

Radiographic images, such as x-rays, mammograms and computed tomography (CT), help detect diseases like cancer in its early stages when treatment can be most effective. As these images are in black and white, detecting the difference between healthy tissue and abnormalities can be difficult.  Now, a new technology called spectral (colour) computed tomography...Read more

In emergency department settings, overuse of computed tomography (CT) for minor head injury continues despite rigorously validated clinical decision rules like the Canadian CT Head Rule (CCHR). Medical experts say one in every three CT scans performed on patients with minor head injury is unnecessary. New research from Yale University has found that,...Read more

2015 17 Nov

Surgeons may one day be able to remove tumours from within the inner ear in a less invasive fashion — ie, without removing the entire mastoid bone. All they will need to do is cut a tunnel of 5 mm in diameter through the bone using a miniature robot named NiLiBoRo. The robotic "worm" can adjust its path while drilling through bone to steer around sensitive...Read more

Neuroimaging is an important diagnostic tool in the assessment of neurological disease, but often unmasks incidental findings (IFs). The negative impacts of IFs, such as patient anxiety, present neurologists with management dilemmas, largely due to the limited knowledge base surrounding the medical significance of these IFs. Specifically, the lack of...Read more
