ICR: Survey reveals major knowledge gaps on radiation dose
September 15, 2014 -- DUBAI - The lack of knowledge among medical staff about radiation dose -- specifically for CT scans -- remains a serious concern, and patients still receive very little information about the pros and cons of scans, according to a survey presented at the International Congress of Radiology (ICR).
ASCO BCS research highlights benefits of mobile mammo, PET/MR
September 15, 2014 -- Screening for breast cancer with mammography isn't perfect -- and neither are the modalities used to track women already diagnosed with the disease. At the recent American Society of Clinical Oncology (ASCO) Breast Cancer Symposium (BCS) in San Francisco, researchers discussed ways to find and track breast cancer more effectively.
Perfusion CT's great potential remains unrealized
September 15, 2014 -- Challenges remain on the road to more precise assessment of tumor treatment response with CT perfusion, but the techniques are already robust and far more sensitive than the old methods based on tumor size. In this emerging field, tumor biology and treatment response combine to make CT an ideal modality for monitoring cancer treatment, according to Boston researchers.
New studies of Egypt's mummies rest on government go-ahead
September 12, 2014 -- DUBAI - Imaging investigations of ancient Egypt's royal mummies may start again in the near future, but this depends on getting the all-important green light from the country's senior politicians, according to the head of the medical team that has conducted previous examinations.
Mich. researchers hope to revamp lung CT image processing
September 12, 2014 -- A new study at the University of Michigan aims to speed up image processing for low-dose CT lung cancer scans in the hopes of reducing reconstruction times to just a few minutes, which should result in lower radiation doses to patients.
ECRI details need-to-know information for buying an MRI scanner
September 12, 2014 -- What key issues should you keep in mind when buying an MRI scanner? Nonprofit research organization ECRI Institute hopes to help with a new report on performance and other measures that radiology departments and imaging centers should consider when purchasing a new system.
Lawsuit attacks CMS policy on PET beta-amyloid scans
September 11, 2014 -- Three women have filed suit against the U.S. Centers for Medicare and Medicare Services (CMS), seeking to invalidate the agency's reimbursement policy for PET beta-amyloid scans to detect early signs of Alzheimer's disease.

New SRU pregnancy criteria won't prompt many more scans
September 11, 2014 -- More stringent diagnostic criteria from the Society of Radiologists in Ultrasound (SRU) for determining early in the first trimester if a pregnancy has no chance of producing a live baby will not lead to a huge increase in follow-up ultrasound exams, San Francisco researchers have found.
Clinical audit sheds light on breast MRI performance
September 11, 2014 -- You can't manage what you can't measure. This maxim by quality expert W. Edwards Deming can easily be applied to breast MRI: Despite its growing use, the exam still lacks adequate benchmarks for assessing quality, according to a study published in the September Journal of the American College of Radiology.
Breast screening controversies spark debate at ICR 2014
September 10, 2014 -- DUBAI - Greater consideration should be given to a woman's total quality of life in the breast screening debate. That was the take-home message of a keynote lecture by Dr. Rola Shaheen at this week's International Congress of Radiology (ICR 2014).
MRI protocol links gray-matter changes to MS severity
September 10, 2014 -- Using a homegrown MRI protocol, researchers found that a loss of myelin in the gray matter of multiple sclerosis (MS) patients' brains was a strong indicator of disease severity, according to a study published online September 10 in Radiology.
Elastography may avoid needless biopsies of thyroid nodules
September 10, 2014 -- Thanks to its high negative predictive value, ultrasound elastography with intrinsic compression may be able to reduce by one-third the number of unnecessary biopsies performed on calcified thyroid nodules, according to research published in the October issue of Ultrasound in Medicine and Biology.
Most common mammo screening barrier? Lack of interest
September 9, 2014 -- In rural Kentucky, the most common barrier to regular mammography screening may be a lack of interest on the part of women, according to research presented at the recent American Society of Clinical Oncology Breast Cancer Symposium in San Francisco.
