CTs Detect Frailty, Predict Survival

2017 06 Jun

Findings from a new study conducted by radiologists at UC Davis and Wake Forest Bapist medical centres suggest that using computed tomography (CT) to evaluate muscle health may help identify optimal treatments for older patients who fall and break their hips. The study is published in the American Journal of Roentgenology. This is the first study that... Read more

Diagnosing Head Injuries in Children

2017 21 Apr

A large-scale, multicenter validation study was conducted to assess the diagnostic accuracy of three clinical decision rules used by emergency doctors. The objective was to determine if it was possible to reduce unnecessary CT scans and radiation exposure in children with head injuries. The outcomes from the trial are published in The Lancet.

Sestamibi SPECT/CT Scan Improves Kidney Cancer Diagnosis

2017 21 Apr

According to results from a series of studies led by researchers at Johns Hopkins Medicine, the addition of a noninvasive imaging test called 99mTc-sestamibi SPECT/CT to CT or MRI increases the accuracy of kidney tumour classification. The researchers believe that using this test could improve diagnostic accuracy and could spare thousands of patients... Read more

Balancing Radiation Doses

2017 14 Apr

According to a new study, radiation doses for common CT scans can be safely and effectively reduced and more consistently administered by assessing and comparing doses across hospitals. The study is published in JAMA Internal Medicine. See Also: Assessment of Radiation Dose Reduction Awareness Over the last decade, there has been a steady increase in... Read more

5 Tests for Better Heart-Disease Risk Prediction

2017 06 Apr

Five simple medical tests – an EKG, a limited CT scan, and three blood tests – together provide a broader and more accurate assessment of heart-disease risk than currently used methods, according to cardiologists at UT Southwestern Medical Center. The findings are published in the journal Circulation.See Also: How Diabetes Increases Heart Attack Risk... Read more

Key Reasons for Repeated CT in Trauma Transfers

2017 24 Jan

Trauma patients often undergo repeated CT scans when being initially examined in another hospital and then are being transferred to a trauma centre, according to a Swiss study published in European Journal of Radiology. Problems with the CT image data transfer were identified as the main reason for CT repetition.See Also: CT for Atraumatic Headache... Read more

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

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
