Study finds few complications from spinal DSA
September 20, 2011 -- Spinal digital subtraction angiography (DSA) has acquired a reputation as a risky interventional procedure, but that notoriety is largely unfounded, according to a study by researchers from Johns Hopkins University that was published online September 14 in Neurology.
Joint Commission issues alert on medical radiation
August 24, 2011 -- The U.S. Joint Commission has issued an alert on the dangers of medical radiation, sending an unmistakable signal that radiology has entered its sights in a formal way. The announcement is a sign that imaging facilities will need to pay more attention to formalizing their procedures for protecting patients from unnecessary radiation dose.
Radiology at home can prevent delirium in elderly patients
August 11, 2011 -- NEW YORK (Reuters Health) - At-home x-rays may reduce the delirium elderly patients can suffer during the procedure, new research suggests. A pilot study of 69 patients found that 17% of those who had x-rays in the hospital -- but none of those treated at home -- suffered delirium and required treatment.
Raising DR tube voltage reduces dose for lumbar studies
August 10, 2011 -- Ignoring manufacturer guidelines for imaging equipment is usually inadvisable, but Kuwaiti researchers have found that doing so for digital radiography (DR) lumbar studies can reduce radiation exposure, according to a poster presentation at last week's American Association of Physicists in Medicine meeting.
Heart test standards all over the map
August 9, 2011 -- NEW YORK (Reuters Health) - U.S. hospitals vary widely in how they decide who's eligible for an invasive type of heart scan, according to a new study. The findings fuel recent concerns about the overuse of coronary angiography, which carries a price tag of several thousand dollars and a risk of side effects.
CR method lowers radiation dose, improves image quality
July 26, 2011 -- Computed radiography (CR) detector technology that uses a storage phosphor plate with needle-shaped crystals can yield lower radiation dose and better image quality in knee imaging than conventional storage phosphor plate methods, according to research in the August American Journal of Roentgenology.
Many U.S. heart stents inappropriate: study
July 6, 2011 -- NEW YORK (Reuters Health) - One in eight U.S. patients who have nonemergency coronary stenting procedures is likely to see more harm than good from the procedure, researchers said on Tuesday.
New phantoms ramp dose estimate accuracy for imaging exams
July 4, 2011 -- Computational human phantoms are invaluable for calculating radiation dose, but the determined values are only strictly accurate for patients with exactly the same anatomy as the phantom. Researchers in Brazil have created a new diverse series of phantoms to improve the situation.
Canadian campaign relies on QC for CR dose reduction
June 20, 2011 -- A three-year effort to optimize quality control (QC) at seven British Columbia hospitals has identified ways to spare patients from unnecessary radiation exposure during computed radiography (CR) exams.
