Breast MRI excels at high-risk screening; mammo not needed February 26, 2010 -- Breast MRI is three times as accurate as other modalities for diagnosing breast cancer early in high-risk women, and it's so good that mammography isn't needed for annual screening of these women, according to a new study by German researchers published online this week in the Journal of Clinical Oncology.
FFDM and CAD find smaller breast tumors February 26, 2010 -- Full-field digital mammography (FFDM) can facilitate increased detection of smaller tumors compared to conventional mammography. But adding computer-aided detection (CAD) technology to FFDM can yield even better results, according to researchers at the Hospital Virgen de la Salud in Toledo, Spain.
CT blood-flow measurement gauges stenosis severity February 26, 2010 -- 64-detector-row CT has sufficient temporal resolution to measure blood flow through the heart, offering the promise of a new functional test based on CT alone, according to a proof-of-concept study by German researchers.
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.
