Novel CT analysis tool refines COPD diagnosis October 9, 2012 -- A new image analysis technique for chest CT scans could have a big effect on the diagnosis and treatment of chronic obstructive pulmonary disease (COPD), according to a new study in Nature Medicine.
New cardiac MRI technique identifies early-stage heart disease October 9, 2012 -- By using a new MRI technique to measure the wall thickness of coronary arteries, researchers from the U.S. National Institutes of Health may be able to identify coronary heart disease early in its progression, according to a study published October 9 in Radiology.
DSCT compares full- to half-dose VC by patient October 8, 2012 -- Mayo Clinic researchers used iterative reconstruction to acquire half-dose virtual colonoscopy exams with dual-source CT (DSCT) and compare them to full-dose exams without scanning patients twice. The technique offers a more accurate way to compare dose levels between different CT protocols, according to a new study in the Journal of Computer Assisted Tomography.
Hybrid linac-MRI tracks motion during radiotherapy October 8, 2012 -- Real-time tumor tracking could prove invaluable for radiotherapy of moving targets such as lung tumors. Using MRI for such tracking provides position verification without ionizing radiation. Researchers recently discussed the latest results of a prototype hybrid linac-MRI system being developed at the Cross Cancer Institute in Canada.
GOP House leaders criticize, ask for halt to stage 2 MU October 5, 2012 -- Republican leaders of the congressional committees in the U.S. House of Representatives overseeing health issues criticized the U.S. Department of Health and Human Services about stage 2 meaningful use (MU) criteria for the adoption of electronic records, and asked that incentive payments be suspended.
Rubidium PET edges SPECT in diagnosing coronary artery disease October 5, 2012 -- PET imaging with the rubidium-82 radiotracer can accurately detect obstructive coronary artery disease and is superior to technetium-99m SPECT imaging, according to a meta-analysis published online October 3 by the Journal of the American College of Cardiology.
Automated tube current, voltage settings cut CT liver dose October 5, 2012 -- A software protocol that enables the use of both automatic tube voltage selection and automatic tube current modulation in the same CT scan can reduce radiation dose significantly in patients with suspected liver disease, according to a new study in Radiology by Korean researchers.
Election 2012: What's at stake for radiology October 4, 2012 -- The upcoming U.S. elections in November will significantly affect the practice of radiology, and radiologists need to understand what's at stake, according to an article published in the October issue of the Journal of the American College of Radiology.
FDG-PET/CT aids in assessing colorectal liver metastases October 3, 2012 -- FDG-PET's ability to assess metabolic tumors appears to be a valuable asset in determining the biology of colorectal liver metastases before surgical resection and may better evaluate patient prognosis, according to a study in the September issue of the Journal of Nuclear Medicine.
