DWI-MRI shows value against PET/CT for oncology March 4, 2010 -- VIENNA - Diffusion-weighted MRI (DWI-MRI) stacks up well against PET/CT in a variety of oncology applications, such as tumor staging and the assessment of metastatic disease, according to presentations on the opening day of the European Congress of Radiology.
1.5-tesla MRI pinpoints, stages testicular masses March 4, 2010 -- MRI is an efficient diagnostic tool to evaluate testicular masses and accurately differentiate between benign and malignant intratesticular tumors, according to a study published in the March issue of the American Journal of Roentgenology.
320-row CT minimizes dose in pediatric abdominal studies March 3, 2010 -- It's no secret that CT radiation dose levels in children -- especially in the emergency department, where patients are fidgety and physicians need fast answers -- are too high. One solution, investigated by researchers from Toronto and Berlin, is wide-area-detector scans with 320-detector-row CT.
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.
