Calcifications on CT distinguish malignant thyroid lesions
May 12, 2010 -- The presence of calcification on CT scans of thyroid nodules can neither prove nor rule out malignancy -- but calcification patterns may be one useful tool that radiologists can use to assess the likelihood of cancer, say researchers from China.
Whole-body MRI workup finds common breast metastases
May 11, 2010 -- Results of a new study indicate that whole-body MRI is an excellent way to work up newly diagnosed breast cancer patients. Researchers from India found that MRI led to a change in treatment in nearly half of patients, and it also found metastases in some patients before symptoms appeared.
CR-based digital mammography beats analog for screening
May 11, 2010 -- In the push to convert to digital mammography, many facilities are using computed radiography (CR)-based systems as an interim step. But just how well does CR mammography compare to traditional analog imaging in a screening environment?
H1N1 crisis helped Canadian rads plan for future pandemics
May 11, 2010 -- The lessons learned during the H1N1 pandemic by a Toronto radiology group are instructive for any radiology department seeking to be maximally effective during both normal conditions and emergencies, according to presentations at the Canadian Association of Radiologists annual meeting held in April in Montreal.
Breast surgeons could be option for reading mammograms

Portable CT scanner recommended for pediatric ICU studies
May 10, 2010 -- Transporting critically ill children from intensive care units (ICUs) to radiology departments can be time-consuming and risky for physiologically unstable patients. Using a portable CT scanner resolves these issues, but does its use compromise image quality and diagnostic accuracy?
Filtering software boosts CT image quality, lowers dose
May 7, 2010 -- Adaptive image filtering can improve CT image quality and reduce image noise, enabling radiologists to lower radiation dose, concluded a study presented at this week's American Roentgen Ray Society meeting in San Diego.
Lung CAD performs best as second reader
May 7, 2010 -- Computer-aided detection (CAD) software yields a higher level of sensitivity for identifying lung nodules as a second reader than when used concurrently during image interpretation, according to research from the University of Verona in Italy.
Hospitals report different experiences with oncology software
May 7, 2010 -- Two hospitals in Sydney, Australia, installed the same oncology information system at about the same time. The radiation oncology departments of both hospitals were enthusiastic and both had computer-proficient physicians and medical staff. Yet three years later, utilization was radically different. What happened?
FAST recommended first for kids with blunt abdominal trauma
May 7, 2010 -- In many emergency departments, CT exams are the imaging study most frequently ordered for patients admitted with blunt abdominal trauma. However, pediatric surgeons and radiologists from Germany recommend that ultrasound combined with clinical assessment is just as effective, thus avoiding radiation exposure.
5-year C-RADS analysis shows stable VC screening results
May 6, 2010 -- SAN DIEGO - In what is likely the largest screening population ever classified by virtual colonoscopy's standardized reporting system, C-RADS, researchers found stable results over five years in the single-center program, along with a large majority of patients who were able to avoid invasive colonoscopy.
Rising service costs prompt hospitals to examine new options
May 6, 2010 -- Cash-strapped hospital administrators are turning to in-house solutions with help from original equipment manufacturers to keep their imaging equipment in good working order, according to a new survey of the diagnostic imaging equipment service industry.
