Surge in CT for Minor Injuries in California

2016 19 Jan

A new study shows increased use of CTs in patients with non-serious injuries, such as fractures or neck strain, treated in emergency departments at California hospitals. The UCSF-led study, which tracked the use of the imaging from 2005 to 2013, found that CTs were more likely to be ordered in hospitals that were designated high-level trauma centres.Some...

Lower Dose, Lower Contrast Possible for CTA Scans

2015 26 Dec

A CTA scan (a scan of the arteries) can be performed with a contrast medium volume reduction of up to 75 percent and up to 50 percent reduction in radiation dose, according to a new study from the University of Twente in Enschede, Netherlands. Researchers say the study's results can almost directly be applied in hospitals today, thus providing enormous... Read more

RSNA15: Conjoined Twins - Role of CT, 3D Printing

2015 03 Dec

In a first, researchers have used CT imaging and 3D printing in the surgical planning for separation of conjoined twins, according to a study presented on Wednesday, 2 December, at the annual meeting of the Radiological Society of North America (RSNA). The 3D models proved to be an excellent source of information, as there were no major discrepancies... Read more

Doctor-Patient Relationship is Key to Reducing CT Scan Overuse in ED

2015 23 Nov

In emergency department settings, overuse of computed tomography (CT) for minor head injury continues despite rigorously validated clinical decision rules like the Canadian CT Head Rule (CCHR). Medical experts say one in every three CT scans performed on patients with minor head injury is unnecessary. New research from Yale University has found that,... Read more

Reduced CT Usage for Common Childhood Diagnoses

2015 27 Aug

Researchers in the U.S. have found a significant decline in the use of computed tomography (CT) scans at children's hospitals for 10 common childhood diagnoses including seizure, severe head trauma and upper respiratory tract infection. They say that alternative imaging modalities such as MRI and ultrasound are being used more frequently for eight of... Read more

New CT Programme for Lung Cancer Diagnosis

2015 13 Jul

Intermountain Medical Center's (Utah, USA) new lung cancer screening programme that uses CT technology provides long-time smokers and past smokers a more accurate way of detecting whether or not they have the disease. The programme is based on the findings of the National Lung Screening Trial, a study that compared CT scans and standard chest X-rays... Read more

Studies Linking Cancer to Medical Imaging Radiation 'Flawed'

2015 02 Jul

Studies purporting to show a link between cancer and medical imaging radiation are flawed because of their reliance on an unproven statistical model, according to a report published in the journal Technology in Cancer Research & Treatment. “Although radiation is known to cause cancer at high doses and high-dose rates, no data have ever unequivocally...

Low Dose CT Screening Needed to Reduce Mortality from Lung Cancer

2015 12 May

ESR/ERS: White paper on lung cancer screeningA joint publication by two major medical societies - the European Society of Radiology (ESR) and the European Respiratory Society (ERS) - advocating the use of low-dose computed tomography to reduce mortality from lung cancer was published on April 30 in their scientific journals, European Radiology and European...

Better CT Scans Improve Disease Insight

2015 11 May

Compact light source (CLS), a commercial x-ray source developed only recently, enables computer tomography (CT) scans that reveal more detail than routine scans performed at hospitals today, a new study has shown. The new x-ray technology could soon be used in preclinical studies and help researchers better understand cancer and other diseases."Our... Read more

Lower Smoking Rate But Higher Lung Cancer Mortality?

2015 26 Feb

A decrease in smoking rates may mean that many people who could have benefited from early detection of lung cancer are dying because they do not qualify for low-dose CT scans, according to a Mayo Clinic-led study reported in JAMA. Lung cancer screening using low-dose computed tomography is recommended for high-risk individuals by professional associations,... Read more
