CAD enhances breast MRI specificity September 17, 2009 -- Although breast MRI is highly sensitive for detecting breast cancer, the technique remains plagued by a relatively low level of specificity. But computer-aided detection (CAD) technology can help reduce false-positive findings, according to research published online this month in European Radiology.
SPECT/CT helps novice clinicians detect arthritic joints September 8, 2009 -- SPECT/CT can help orthopedic surgeons and radiologists identify multiple arthritic joints in the feet and ankles and localize degenerative joint disease, according to a study published in the September issue of the British edition of the Journal of Bone and Joint Surgery.
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.
