Development efforts aim to facilitate CEUS for molecular imaging
May 14, 2010 -- ATLANTIC CITY, NJ - Contrast-enhanced ultrasound (CEUS) offers much potential for molecular imaging applications such as in vivo imaging of angiogenesis and assessing disease states for therapy monitoring. Researchers described the state of the art in CEUS in a presentation this week at the Leading Edge in Diagnostic Ultrasound conference.

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
May 10, 2010 -- Dedicated breast surgeons are an excellent alternative to specialized breast radiologists for interpreting mammograms, especially in the face of what some say is a shortage of mammography specialists, according to a study presented at the recent American Society of Breast Surgeons meeting in Las Vegas.
Medical societies challenge CMS proposal for EHR adoption
May 10, 2010 -- Fifty-two of the largest and most influential medical professional societies and organizations in the U.S. have united to recommend major changes in the electronic health record (EHR) incentive programs proposed by the Obama administration.
