VC obviates need for colonoscopy even in symptomatic patients February 24, 2010 -- Even among individuals with symptoms suggesting a higher risk of colorectal polyps and cancer, virtual colonoscopy screening is enough to prevent most of them from having to undergo invasive colonoscopy, according to a recent study from the Netherlands.
MRI enterography shows shortcomings for Crohn's disease February 23, 2010 -- Although MRI enterography can diagnose important incidental findings in a minority of patients with suspected or known Crohn's disease, Dutch researchers have concluded that a substantial number of patients experience unnecessary morbidity because of additional examinations of benign or normal conditions.
Coronary CTA and MR MPI have complementary roles February 22, 2010 -- Coronary CT angiography (CTA) and MR myocardial perfusion imaging (MPI) work best as a team for evaluating chest pain patients with suspected coronary artery disease, according to a new study published online in Radiology.
Covidien signs deal to produce Mo-99 at Polish reactor February 17, 2010 -- Healthcare technology firm Covidien has inked an agreement with the Institute of Atomic Energy in Poland to augment Covidien's supply of molybdenum-99 (Mo-99), which is used in the production of the medical isotope technetium-99m.
PET/CT cost-effective for head, neck squamous cell carcinoma February 17, 2010 -- FDG-PET/CT is not only most effective for pretreatment screening of distant metastases in patients with head and neck squamous cell carcinoma, the combined modalities do so with no additional costs to healthcare providers, according to researchers in the Netherlands.
Contrast MRI helps guide stem cell therapy for myeloma February 11, 2010 -- Researchers from France have found that whole-body dynamic contrast-enhanced MRI can help assess treatment response in patients receiving stem cell therapy for multiple myeloma by providing quantitative analysis of bone marrow and focal lesion enhancement.
Study to compare 320-row CT perfusion against SPECT February 10, 2010 -- Following up on the CORE 64 study that tested the value of coronary CT angiography vis-à-vis angiography, researchers have launched a new international trial to compare 320-detector-row CT perfusion to SPECT myocardial perfusion imaging for detecting early coronary artery disease.
Italian rad oncologists go proactive to reduce adverse events February 8, 2010 -- The recent series of articles in the New York Times on errors in radiation therapy has experts searching for better ways to prevent adverse events. Researchers from Italy may have found one solution by replacing the conventional "reactive" methods for risk management and quality assurance with a more proactive approach.
320-row perfusion CT shows promise for pancreatic tumors February 5, 2010 -- Perfusion CT with a 320-detector-row scanner offers improved resolution of pancreatic tumors due to its ability to image the entire organ without slice overlap, according to researchers from Berlin and Toronto.
New ultrasound techniques show promise in thyroid nodules February 5, 2010 -- Differentiating benign from malignant thyroid nodules can be difficult, but advanced ultrasound applications such as elastography, computer-assisted analysis, and 3D ultrasound may make that challenge a little easier, according to a trio of presentations at the 2009 RSNA meeting in Chicago.
