Susceptibility-weighted MRI proves viable in stroke cases
February 23, 2012 -- Susceptibility-weighted MR imaging is a viable alternative to perfusion-weighted MR imaging to assess reduced blood flow and predict stroke evolution, according to a study published online on 10 February in European Radiology.
Nepal offers mountainous challenges to radiology
February 22, 2012 -- Nestled between India and China, Nepal is a mountainous country with major differences between urban and rural regions -- including access to imaging technology. But simple changes can make a big impact, according to Yogesh Jha, a former radiographer in Nepal who spoke with on the state of radiology in his home country.
7T MRI protocol shows brain plaques in MS patients
February 22, 2012 -- A new study published online February 20 in Archives of Neurology suggests that 7-tesla MRI with a specialized protocol is highly sensitive for detecting plaques in white and gray brain matter in patients with multiple sclerosis (MS).
Radiotherapy skin care treatment uneven in U.K.
February 21, 2012 -- One of the most common side effects from external-beam radiation therapy treatments are skin reactions. Yet there is no uniformity in assessment or treatment among radiotherapy departments in the U.K., according to an article in the February issue of Radiography.
MRI shows benefits of Mediterranean diet on the brain
February 20, 2012 -- The fabled Mediterranean diet may be good for your brain as well as your waistline. MRI has revealed that people who adhere to the diet have reduced brain white-matter hyperintensity volume, thus reducing their chance of chronic small-vessel damage, according to a study in the February issue of Archives of Neurology.
Heart failure, ischemia, tied to gray-matter loss at MRI
February 17, 2012 -- Heart failure is associated with gray-matter loss at MRI and a worsening of both memory and psychomotor skills. To a lesser extent, the presence of ischemic heart disease slows recall as well, according to a new study in the European Heart Journal.
'Virtual phantom' helps guide dose reduction in CR studies
February 16, 2012 -- U.K. researchers have developed a computer-based simulator for estimating radiation dose in computed radiography (CR) studies. The researchers believe their "virtual phantom" could prove more effective than physical phantoms by enabling clinicians to gauge the impact of patient anatomy when imaging parameters are changed.
CT shows moderate sensitivity for spinal injuries
February 15, 2012 -- Whole-body CT has excellent specificity but imperfect sensitivity for detecting spinal injuries in blunt trauma, concluded German researchers presenting at the 2012 American Academy of Spinal Surgeons meeting held earlier this month in San Francisco.
Choline-PET/CT changes prostate cancer treatment plans
February 14, 2012 -- Swiss researchers have found that PET/CT scans with the radiopharmaceutical choline can change treatment plans for certain patients with recurrent prostate cancer. Study results showed that choline-PET/CT significantly affected therapy management.
Female radiologists: Does gender really matter?
February 13, 2012 -- In her latest column, Dr. Anagha Parkar discusses whether gender matters in medicine. More women are entering the field but there is an imbalance regarding certain subspecialties. What does that mean for radiology?
