good news they ain't talkin bout us... and imho, i think GE/TOSHIBA ought to seriously consider aquiring us...

here's the editorial... now, you best make a point when you offer solutions...

"First, radiation protocols should be improved to eliminate the 13-fold difference in radiation dose for the same CT scan; exposures will be significantly reduced if all institutions were to use the lowest-dose technique. Smith-Bindman and colleagues3 found, for example, that the "usual" protocol sometimes unwittingly increased radiation. The authors offer several techniques to improve the quality of CT scans."

now, here are the two articles:

1st:

Projected Cancer Risks From Computed Tomographic Scans Performed in the United States in 2007

Amy Berrington de González; Mahadevappa Mahesh; Kwang-Pyo Kim; Mythreyi Bhargavan; Rebecca Lewis; Fred Mettler; Charles Land

Arch Intern Med. 2009;169(22):2071-2077.

http://archinte.ama-assn.org/cgi/content/full/169/22/2071

Excerpt:
Reduction in risk could be achieved in a number of ways, including decreasing the number of unnecessary procedures as well as the dose per procedure. ***The American College of Radiology appropriateness criteria36 are an important tool for helping physicians to make the most appropriate imaging decisions for specific conditions, and widespread use of these criteria should reduce unnecessary CT scans.*** Mechanisms to evaluate appropriate dose levels, as well as guidance for reducing dosages, including reference levels for radiation dose,37 are available, and participation in radiation dose registries, such as the recently initiated American College of Radiology registry, can provide institutions with feedback on their radiation exposure levels in comparison with other institutions.38

2nd:

Radiation Dose Associated With Common Computed Tomography Examinations and the Associated Lifetime Attributable Risk of Cancer

Rebecca Smith-Bindman; Jafi Lipson; Ralph Marcus; Kwang-Pyo Kim; Mahadevappa Mahesh; Robert Gould; Amy Berrington de González; Diana L. Miglioretti

Arch Intern Med. 2009;169(22):2078-2086.

http://archinte.ama-assn.org/cgi/content/full/169/22/2078

Excerpt:
Consensus is growing that patients' exposure to radiation through medical imaging needs to be reduced, and we believe that 3 general approaches should be taken. First, CT examination protocols and techniques should be optimized and standardized to limit the radiation associated with individual scans. ***This would include standardizing protocols across sites, reducing multiple series within each examination, implementing dose reduction strategies, and encouraging participation in accreditation programs such as that offered by the American College of Radiology. In practice, these guidelines have not been widely embraced, perhaps because no regulatory component is associated with their use.*** ... A second approach to minimize medical radiation exposure should focus on reducing the number of CT examinations. Although difficult to fully assess, it has been reported that 30% or more of the CT examinations currently performed may be unnecessary. ... The third approach to reducing exposure may be to track and collect dose information at the patient level because patients may undergo repeated imaging over time.13

now, i want everyone to note one of the authors appearing in both articles...

Mahadevappa Mahesh

this is a very bright individual... i cited him in the current manuscript/paper on radiation exposure i have under evaluation for final acceptance to a journal...

also, he was the author of the article with which i used to get the picture of the 4th generation CT machine i posted about this weekend and today...

http://radiographics.rsna.org/content/22/4/949.full

importantly M MAHESH is the author of the paper i posted before when i was talking about method to minimize fluoroscopic dose...

here's all of his articles from radiographics:
