Latest X-ray computed tomography Stories

X-ray images known as CT scans can help confirm gout in patients who are suspected of having the painful condition but receive negative results from traditional tests, a Mayo Clinic (http://www.mayoclinic.org) study has found. The type of CT scan analyzed, dual-energy computed tomography, also is valuable for diagnosing people who cannot be tested with the typical method of drawing fluid from joints, researchers found. The study is being presented at the American College of Rheumatology...

According to a recent study published in the November issue of the Journal of the American College of Radiology, many radiologists disagree on the management of incidental findings found on body computed tomography (CT) scans. An incidental finding is something found that is unrelated to the present illness and is discovered unintentionally. Advances in CT resolution have improved radiologists' ability to identify small or subtle findings. In conjunction with increasing CT utilization,...

WASHINGTON, Oct. 27, 2011 /PRNewswire/ -- The Smithsonian's National Museum of Natural History has pioneered the use of CT scanning technology in non-invasive scientific research. Now, with the gift of a Siemens SOMATOM Emotion 6 CT scanner from Siemens Healthcare, Smithsonian researchers are acquiring information about museum objects that is fundamentally changing the way scientists examine specimens.

SAN DIEGO, Oct. 27, 2011 /PRNewswire/ -- The Breast journal published new data from a prospective study conducted at the Seoul National University College of Medicine in Korea that shows Positron Emission Mammography (PEM) has a higher sensitivity for tumor detection compared to whole-body PET/CT when using both visual as well as quantitative analysis. These results were particularly striking and significant for smaller-sized tumors (less than 2 cm), likely due to the improved spatial...

(Ivanhoe Newswire) -Do you experience shortness of breath while performing the most basic tasks such as doing light housework, taking a walk, or even washing and dressing? If you answered yes, then you might want to get checked for COPD. COPD or chronic obstructive pulmonary disease usually develops among men who were current or former heavy smokers. "Smoking is annually projected to cause more than 8 million deaths worldwide in the coming decades. Besides cardiovascular disease and...

Recent studies have suggested that C-11 choline positron emission tomography/computerized tomography (PET/CT) scans can be utilized as a staging and potentially therapeutic tool in prostate cancer. The results of three studies, released today during a meeting of the North Central Section of the American Urological Association (http://www.ncsaua.org/default.aspx), validate findings in Europe and expand the potential use of C-11 choline PET scans. One study found that C-11 choline PET/CT...

High-definition CT scans reduce radiation exposure Canadian Journal of Cardiology (www.onlinecjc.ca) has published a paper on the safety of cardiac imaging methods. This study is important for patients worried about radiation exposure during X-ray based studies of the heart. X-ray based methods have greatly improved the diagnosis of heart disease, but they can produce significant levels of radiation exposure. New imaging methods offer the possibility of much safer external...

PHOENIX, Oct. 19, 2011 /PRNewswire/ -- VisionGate, Inc., a company developing a revolutionary non-invasive test for the early detection of lung cancer, today reported that it has raised approximately $2 million in the first tranche of a financing round. The company also announced that it has entered into a collaboration with the Sheba Medical Center in Israel to evaluate whether VisionGate's LuCED(TM) test can reduce false positive results when used in conjunction with x-ray computed...

White children are far more likely to receive cranial computed tomography (CT) scans in an emergency department following minor head trauma than are African-American or Hispanic children, a study by researchers at UC Davis has found. The study findings do not indicate that CT scans are underused in treating African-American and Hispanic children, the researchers said. Rather, they suggest that white children may receive too many CT scans -- and for that reason may be exposed to unnecessary...
