Facial transplants: Low-dose methods prove vital to success
December 6, 2013 -- CHICAGO - The complexity and extent of follow-up imaging often required in cases of facial transplantation means the application of all available low-dose imaging techniques must be pursued, according to top award-winning research presented at RSNA 2013.
Allez-y! French charm offensive hits RSNA 2013
December 3, 2013 -- CHICAGO - Gallic genius, flair, and innovation came under the spotlight at the RSNA annual meeting on Monday during a celebration of France's many contributions to cancer imaging. Four experts from France spoke during the special session.
Superresolution ultrasound maps the brain
November 29, 2013 -- Researchers have overcome an inability of ultrasound to map capillaries and other vessels in the brain by injecting micrometer-sized bubbles into the bloodstream. Although the technique has been demonstrated only on a model brain so far, it's a promising new way to map the brain's vascular networks.
Study finds positive radiation dose trends in Iran
November 28, 2013 -- A study of occupational radiation dose and errors in film badge use by CT staff at a university hospital in Iran found that radiation exposure remained low and errors declined over a 20-year period, despite an annual increase in the number of patients undergoing scans.
CORE320: CTA-CTP matches SPECT for gauging cardiac disease
November 27, 2013 -- The accuracy of 320-detector-row coronary CT angiography (CTA) combined with CT perfusion (CTP) is equivalent to that of SPECT myocardial perfusion for diagnosing functionally significant coronary artery disease, according to results of the prospective, multicenter, international CORE320 trial published in the European Heart Journal.
Major obstacles remain for postmortem CT, Swiss experts warn
November 26, 2013 -- The development of postmortem CT angiography represents a significant step forward to minimally invasive autopsies, but considerable work still has to be done before it can replace the conventional autopsy, Swiss researchers have found.
Dinosaur vertebra fossil rises up in 3D from CT data
November 21, 2013 -- Noninvasive imaging techniques have long proved valuable for digging up the stories of fossils without damaging them. In a new study published online in Radiology, German researchers have gone a step further, making a carbon copy of a dinosaur vertebra using CT data and 3D printing.
CT brings clarity to forensic identification
November 19, 2013 -- In forensic cases, multislice CT now plays a crucial role in comparative identification, reconstructive identification, and lesion identification, and has important advantages over dry bone analysis, according to French researchers.
Siemens unveils ultralow-dose Somatom Force DSCT scanner
November 15, 2013 -- Siemens Healthcare unveiled its latest CT scanner, Somatom Force, in a demonstration at University Medical Centre Mannheim in Germany. A dual-source system (DSCT), Somatom Force introduces several features aimed at making CT scanning safe and accurate for the most sensitive patients.
Digital tomo can guide lung stereotactic body radiotherapy
November 15, 2013 -- Image guidance using motion-compensated digital tomosynthesis has the potential to improve targeting accuracy during treatment of lung cancer patients, according to researchers from The Netherlands Cancer Institute in Amsterdam.
French show how to optimize patient dose in lower limb scans
November 14, 2013 -- Using a stereoradiography system on the lower limbs in a standing position to calculate patients' morphologic and static parameters can result in a much lower x-ray dose to the ovaries and testes than with CT, French researchers have found.
Radiology 20/20 vision: Will science fiction become reality?
November 13, 2013 -- LONDON - Radiology must fully embrace new training pathways and translational research so that young doctors are capable of progressing research from the laboratory to the clinic, a senior radiologist noted in a broad-ranging, visionary, public lecture on Thursday evening.
EU study charts path to cost-effective cardiac imaging
November 12, 2013 -- BRUSSELS - Imaging has brought unprecedented insight into cardiovascular disease, but health authorities need smarter and more cost-effective screening strategies to identify high-risk patients, according to a research project presented on Thursday at a special European Parliament hearing in Brussels.
3D workstations enhance EVAR planning, outcomes
November 11, 2013 -- Using 3D workstations for planning endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms (AAA) can improve both short- and midterm outcomes for patients, researchers from France have found.
Work more closely with rheumatologists, urge U.K. experts
November 8, 2013 -- Better cooperation between radiologists and rheumatologists is essential to ensure imaging is used cost-effectively to provide clinical information on diagnosis, prognosis, and serial assessment with the least risk and inconvenience to the patient, two U.K. researchers said.
