MDCT, SPECT, and echo agree on LV function

Sure, multidetector-row CT can do arteries, but how about global and regional left ventricular (LV) function? It can indeed assess them accurately, researchers from the Netherlands reported in the European Journal of Nuclear Medicine and Molecular Imaging.

Part II: Virtual autopsy promises better data on U.S. military casualties

Our final installment on the growing use of CT in autopsy discusses its use in the U.S. military, which since 2005 has performed whole-body multislice CT as part of a comprehensive forensic and pathological assessment of every soldier, sailor, airman, or Marine killed in a theater of war. An officer from the Armed Forces Institute of Pathology details the successes and the problems encountered in the high-volume scanning operation.

Elderly need less contrast for pancreatobiliary imaging

Older patients need less contrast than younger adults for pancreatobiliary imaging, researchers from Japan report. The results of their study, published in the August American Journal of Roentgenology, showed that a 12% contrast dose reduction by body weight produced the optimal contrast profile in multidetector-row CT's triphasic imaging protocols.

2D, 3D primary VC have their own advantages

There's no right or wrong choice for primary reading when it comes to 2D or 3D virtual colonoscopy. But whichever method you choose, you'll need the other to confirm the findings. Dr. Judy Yee from the University of California, San Francisco, recently discussed both primary reading methods, and some of the latest study results on 2D versus 3D.

Study: 16-MDCT yields too many nonevaluable artery segments

Low-dose 16-slice MDCT angiography should not be recommended for the routine nonemergency evaluation of patients with chest pain and an intermediate or high probability of coronary artery disease, according to the authors of a new study in this week's Journal of the American Medical Association.

Window levels matter when viewing submerged polyps in VC

Tagging regimens are increasingly popular among virtual colonoscopy providers, who want to optimize lesion conspicuity and thereby avoid undetected lesions. But finding submerged polyps in 2D means paying careful attention to the attenuation of tagged fluid and window settings, according to new research from the U.K.

Canadian lung CAD cuts false positives

At the Computer Assisted Radiology and Surgery (CARS) conference in Osaka, researchers from Canada presented a CAD algorithm that can distinguish between faint and similarly shaped lung structures, reducing false positives with the aid of a hybrid learning scheme that uses both linear discriminant analysis and fuzzy c-means clustering.

X-ray reveals python's too-hot dinner

A 12-foot Burmese python swallowed an electric blanket -- electrical cord, control box, and all -- but will probably survive to eat another meal. X-ray images show the tangle of the blanket's wiring extending through the python's digestive tract.

Extracolonic findings double VC costs, but might be worth paying

Following up extracolonic findings in virtual colonoscopy can easily double the cost of exams in symptomatic patients, but even the occasional detection of significant pathology may make it cost-effective, researchers from the U.K. report.
