Dear CT Insider,
Multidetector CT is used often to evaluate the pelvis, but detailed anatomical knowledge is essential to distinguish the precise location of the affected structures and establish a differential diagnosis, say researchers from Toledo, Spain.
In a top ECR 2014 e-poster presentation, a Spanish team gave a series of practical hints on how to achieve success in pelvic CT examinations. To learn more, go to your CT Digital Community, or click here.
Phase-contrast CT is a promising technique that exploits variations in x-ray phase, instead of absorption, to produce superior soft-tissue contrast to conventional CT scanning. Researchers from Germany and France have conducted studies on its usefulness, particularly in breast imaging, and you can read about their findings here.
Contrast-induced nephropathy has been overestimated, believe radiologists from Denmark. They constructed a study of fluctuations in estimated glomerular filtration rates in relation to contrast-enhanced CT and MRI, and compared them with outpatient control groups. Get the story here.
CT colonography (CTC) continues to make steady progress in the clinical arena. A new study of nearly 400 patients has shown that more efficient detector circuitry can reduce image noise in CTC by about 10% -- or, alternatively, reduce radiation dose by about 20% if noise levels were to remain unchanged.

When it comes to investigating Egyptian mummies and other ancient artifacts, CT generally is the modality of choice. Visualization experts and radiologists from Sweden are conducting pioneering work in this area, and they're focusing on the use of dual-energy CT. You can click here to read about it.
