RT plus chemo can preserve larynx in head and neck cancer
February 26, 2010 -- Induction chemotherapy followed by radiation therapy (RT) has produced good outcomes in larynx preservation for patients with advanced head and neck cancers, according to data presented this week at the Multidisciplinary Head and Neck Cancer Symposium in Chandler, AZ.
CT explores size, growth of ground-glass nodules
February 24, 2010 -- Two studies recently published online in Radiology yield important new information about CT-detected part-solid lung nodules. Mass measurements of ground-glass nodules are the most accurate, say Dutch researchers, but a Korean group found that most part-solid nodules disappear over time -- and do so in predictable ways.
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.
