MRI perfusion imaging can help determine brain tumor progression

Gliomas, the most common malignant brain tumors in adults, can be difficult to treat because of their aggressive and invasive nature. In treating patients with gliomas, it is increasingly important that doctors be able to detect tumor changes early when there's a better chance for recovery.

MRI reveals microgravity-induced intracranial hypertension in astronauts

Magnetic resonance imaging (MRI) of the eyes and brains of 27 astronauts who have spent prolonged periods of time in space revealed optical abnormalities similar to those that can occur in intracranial hypertension of unknown cause, a potentially serious condition in which pressure builds within the skull.

Study reveals significant variation in use of head computed tomography

Imaging has been identified as one of the key drivers of increased healthcare costs. A new study from Brigham and Women's Hospital and Harvard Medical School has found significant variation in the use of head computed tomography (CT), even within a single emergency department. Strategies to reduce such variation in head CT use may reduce cost and improve quality of care.

Unknown 'root' extension in hair cells of the inner ear

The hair cells of the inner ear have a previously unknown "root" extension that may allow them to communicate with nerve cells and the brain to regulate sensitivity to sound vibrations and head position, researchers at the University of Illinois at Chicago College of Medicine have discovered. Their finding is reported online in advance of print in the Proceedings of the National Academy of Sciences.

Women with breast pain do not gain benefit from imaging

Researchers from Boston University School of Medicine (BUSM) and Boston Medical Center (BMC) have found that women with breast pain who receive imaging (mammograms, MRIs or ultrasounds) as part of breast pain evaluation, undergo follow-up diagnostic testing, but do not gain benefit from these additional studies.

Concussion in kids may lead to memory and cognitive problems at school later in life

The researchers from Nationwide Children’s Hospital and The Ohio State University looked at 186 children aged 8 to 15 who experienced concussion - most commonly in a fall or while playing sports - or other brain injury from a car accident or other causes. The children’s parents were asked to fill out a standard questionnaire to assess their child’s cognitive and physical status before the concussion, and again two weeks, three months and a year later. These responses were compared to those from parents of 99 similar children who came into the emergency room with orthopedic injuries.

Whole-body CT more effective at determining life-threatening injuries

For assessing severe trauma, single-pass whole-body computed tomography (CT) can prove but not definitively exclude the presence of injuries and should be performed later than 30 minutes after admission to an emergency department for optimal results, according to a study in CMAJ.
