MRI finds proximal femur fractures missed by x-ray September 1, 2009 -- MRI can detect a significant number of fractures of the proximal femur that are missed by plain radiography, as well as prompt early diagnosis and initiation of treatment, according to a British study.
Advanced image processing stitches together CE images August 31, 2009 -- An image processing technique forged in Japan could make wireless capsule endoscopy (CE) more useful by analyzing and cobbling together the somewhat unpredictable sequence of small intestine images generated by the tiny capsule endoscopy cameras.
Most choose VC over colonoscopy, study shows August 27, 2009 -- A new study from the Netherlands has found that most patients preferred reduced-prep virtual colonoscopy over conventional optical colonoscopy. Patients judged reduced-prep VC, both prep and procedure, as less burdensome, a fact the researchers hope could lead to greater compliance in colorectal cancer screening.
Brazilian team marries lung CAD with PACS August 20, 2009 -- Nearly all computer-aided detection (CAD) systems in clinical use today have a major shortcoming: the need to transfer image data to a separate workstation to run CAD software, with CAD data remaining separate from the PACS images radiologists read in their normal workflow. Researchers from São Paulo may have the answer.
Noncontrast CT with PET reduces melanoma radiation dose August 12, 2009 -- Using a low-dose protocol and eliminating contrast from the CT portion of PET/CT studies resulted in only slightly lower sensitivity for detecting metastases in melanoma patients, while delivering less radiation and no exposure to potential contrast reactions, German researchers found.
Dual-source coronary CTA has advantages over 64-slice August 7, 2009 -- Even in patients with well-controlled heart rates, dual-source coronary CT angiography (CTA) delivers significantly higher specificity and accuracy per coronary segment compared to 64-detector-row CTA, concludes a new study from Switzerland.
How I do it: CT perfusion in functional tumor imaging August 7, 2009 -- Many hospitals make the decision to acquire CT perfusion technology and software primarily for stroke diagnosis; however, the technique can also yield valuable results in functional tumor imaging. That's according to Dr. Ken Miles, who explains how to optimize CT perfusion protocols to produce accurate and consistent tumor imaging results.
IAEA study finds that interventional dose may be too high August 5, 2009 -- Many patients at hospitals in developing countries may be getting too much radiation dose during interventional radiology and cardiology procedures, according to a study sponsored by the International Atomic Energy Agency (IAEA) and published in the August issue of the American Journal of Roentgenology.
Lower-kilovoltage coronary CTA maintains image quality August 5, 2009 -- In a study that included all but the heaviest cardiac imaging patients, European and Japanese researchers were able to cut radiation dose by 31% in coronary CT angiography (CTA) studies by reducing the kilovoltage from 120 kV to 100 kV, with no difference in image quality.
Sophisticated electronic bowel cleansing boosts polyp detection August 3, 2009 -- A new suite of investigational image-processing tools known as structure-analysis cleansing is improving the results of virtual colonoscopy scans performed after limited bowel preparation. The goal is to make virtual colonoscopy easier on patients and persuade them to get screened for colorectal cancer.
