MRI aids differentiation of traumatic cerebral fat embolism
September 18, 2014 -- An Egyptian-led team of MRI researchers reported at last week's International Congress of Radiology that cerebral fat embolism (CFE) can be differentiated from diffuse axonal injury because CFE has a higher incidence of increased T2-FLAIR and diffusion-weighted imaging lesions.
Ultrasound should be 1st choice for suspected kidney stones
September 18, 2014 -- Ultrasound should still be the first imaging test of choice for evaluating patients with suspected nephrolithiasis, according to research published in this week's issue of the New England Journal of Medicine. The study found that using CT first didn't yield better clinical outcomes.
FDG-PET/CT benefits breast cancer patients younger than 40
September 17, 2014 -- While guidelines recommend FDG-PET/CT only as an optional workup for women with stage III breast cancer, the hybrid modality can help women younger than 40 who have potentially aggressive stage II breast cancer, according to a study published online September 11 in the Journal of Nuclear Medicine.
Incomplete documentation jeopardizes radiology payments
September 17, 2014 -- Insufficient documentation is behind most improper payments, according to the government agencies responsible for policing Medicare program claims. Those same agencies repeatedly advise healthcare providers that they can avoid errors by complying with documentation requirements, including those in local coverage determinations.
ASTRO: Imaging, radiation oncology increasingly work as one
September 16, 2014 -- SAN FRANCISCO - Imaging is central to the unprecedented wave of medical specialties converging on cancer care. But it will take more than what today's radiologists are trained for to better understand cancer's mysteries, according to a keynote address by Dr. Hedvig Hricak, PhD, on Monday at the American Society for Radiation Oncology (ASTRO) meeting.
Transcranial US can spot carotid stenosis patients in danger
September 16, 2014 -- Transcranial Doppler ultrasound can be used to identify those asymptomatic carotid artery stenosis patients who are at greater risk for stroke and would therefore be most likely to benefit from revascularization procedures, according to research published online September 16 in Radiology.
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. The litigation charges that CMS overstepped its authority when it implemented the policy last year.
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.
