ASNC: Should nuclear technologists read SPECT MPI scans?
September 22, 2014 -- BOSTON - Nuclear medicine technologists were nearly as accurate as cardiologists in reading stress-first SPECT myocardial perfusion imaging (MPI) studies, according to research presented at the American Society of Nuclear Cardiology (ASNC) meeting. The study hints at a role for technologists in determining which patients could avoid the rest portion of the scans.
Big spectral CT project launches in New Zealand
September 22, 2014 -- You've heard of dual-energy CT, but how about eight-energy CT? That's the goal of researchers in New Zealand, who this month received funding for a project to build a CT scanner capable of detecting eight different energies at once in scans of humans. They hope the new spectral scanner will offer functional imaging that is unprecedented for CT, with a lower radiation dose to boot.
Sandy's silver lining: Hurricane creates impetus for change
September 19, 2014 -- NEW YORK CITY - Hurricane Sandy was a catastrophic event for New York City, but it did have a silver lining for NYU Langone Medical Center's radiology department. With help from informatics, the storm precipitated significant and lasting workflow and quality improvements, according to a Thursday talk at the New York Medical Imaging Informatics Symposium.
ASTRO: Radiation therapy cost analysis suggests inefficiency
September 18, 2014 -- SAN FRANCISCO - A new analysis of radiation therapy costs presented at this week's American Society for Radiation Oncology (ASTRO) meeting has found wide variations that aren't related to patient or disease factors. Costs varied between standalone centers and hospital departments -- a variance that has since been flattened by changes in Medicare reimbursement.
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.
