High methodological quality studies of PET in malignant melanoma patients needed

The relevance of positron emission tomography (PET) alone or in combination with computed tomography (CT) in patients with malignant melanoma cannot be currently assessed due to a lack of meaningful studies. This is the result of a final report published by the German Institute for Quality and Efficiency in Health Care (IQWiG) on 20 July 2011.

Earlier Alzheimer’s disease and dementia diagnosis: New guidelines

It has been the tradition to confirm the presence of Alzheimer's disease during autopsy. However new guidelines proposed on Sunday by the U.S. National Institute on Aging and the Alzheimer's Association seek to distinguish between memory changes or dementia diagnosed by doctors when people are alive, and the changes pathologists can see in an autopsy.

Battle lines drawn in the CT dose reduction arena

Over the past ten years, Computed Tomography (CT) vendors have been in a fierce race to capitalise on the trend for multi-slice CT equipment. However, in the last three years, increasing concerns over radiation exposure from CT examinations have driven a focus on dose-reduction, and CT product development has followed suit. As battle lines are drawn in the dose-reduction arena, InMedica (www.in-medica.com) analyses the competition for CT slices in its new report “The World Market for CT and PET-CT Equipment.” Importantly, what will this mean for dose-reduction?
