Biological dose measures promise new view of cardiac imaging risk May 1, 2009 -- The development of biological radiation dose measurement portends a future of far greater accuracy in gauging the damage wrought by ionizing radiation in imaging exams. Two studies, focused on cardiac CT and conventional angiography exams, respectively, offer the potential of maximizing image quality while minimizing the potential radiation risk to the patient.
US replaces x-ray for diagnosing childhood constipation April 27, 2009 -- British pediatricians at a London children's hospital are using ultrasound to assess the severity of constipation in children. They have found that ultrasound is a good substitute for abdominal x-ray, with its radiation exposure, or a digital rectal examination, a procedure that children find unpleasant and disturbing.
New technology spurs investment in brachytherapy April 23, 2009 -- The U.S. market for brachytherapy products should exceed $1 billion in the next five years, driven by the introduction of new products that allow accelerated treatment for cancer patients after surgery. The worldwide market could grow even more rapidly, according to this analysis from market research firm Bio-Tech Systems.
VC CAD plus 3D improves sensitivity for novice readers April 21, 2009 -- Computer-aided detection (CAD) with 3D viewing improves sensitivity for polyp detection among less experienced readers, and may also speed up reading times and reduce false-positive detections. On the other hand, the performance of experienced readers did not improve significantly with CAD use, researchers from the University of Rome concluded.
IHE's XDS-I profile may help with CD import dilemma April 14, 2009 -- Institutions that struggle with managing patient CDs from outside locations should consider taking advantage of the Integrating the Healthcare Enterprise (IHE) Cross-enterprise Document Sharing for Imaging (XDS-I) integration profile, according to a presentation at the 2009 European Congress of Radiology.
Gated SPECT best indicator for cardiac events April 13, 2009 -- Myocardial perfusion abnormalities obtained after stress, as well as the extent of scar tissue detected by gated SPECT, are the best predictors of cardiac events in patients with suspected or known ischemic heart disease, according to a new Italian study.
U.K. specialists want relevancy, detail in radiology reports April 10, 2009 -- Radiology reports that are most beneficial include clinical comments and are presented in a consistent, easy-to-read tabular format, according to a survey of physicians ordering radiology procedures from a community hospital in northwest England.
Adding chest CT to VC not cost-effective, study finds April 7, 2009 -- Adding a chest CT scan to screening virtual colonoscopy isn't cost-effective in a cohort of average-risk patients, a new model-based analysis concluded. Although the additional anatomic coverage increased the clinical efficiency of CT-based screening, the combined test would not detect enough serious pathology to cover the costs of detection and follow-up of disease.
