Calculate the risk of cancer from CT radiation

Two new studies published in the Archives of Internal Medicine have calculated the exact risk of cancer from exposure to radiation during computed tomography (CT).

In a study Rebecca Smith-Bindman, MD, and colleagues, a retrospective cross-cross-cross sectional study to determine the radiation dose of 11 common types of diagnostic CT examinations. E ‘included 1119 consecutive adult patients, with 4 of the San Francisco Bay, California between January 1 and May 30, 2008.They found that on average 13 times the difference between the maximum radiation dose and lose the same type computed tomography. The number of technical assistance that leads to cancer depends on patient age, sex and type of CT. The study found that 1 in every 270 women who are cancer, coronary quarantine of exposure to radiation from CT studies. The risk was doubled in 20 years and reduced to 50% of patients aged 60 years.

Exploration In the second study said Amy Barrington de Gonzalez and colleagues at future risk of cancer using CT in the present United States by age, sex and type. The study found that CT scan was 72 million in 2007 in the United States and caused 29 000 in cancer of the future together, these explorations. Important contributions have been one of the abdomen and pelvis, chest, head and chest CT and angiography. One third of the tumors were examined, since the scans are 35 to 54 years compared to 15% due to the tests carried out at a younger age of 18 years and 66% were women. Data were collected from the CT scan of a large database of commercial insurance; Medicare claims data and survey data from IMV Medical Information Division.

Now that studies cancer risk of radiation with precision CT, physicians and radiologists evaluated the patient should be clinically examined thoroughly before the need for the scanner. There should be strict guidelines on the quality of TDM, particularly in relation to the level of radiation caused by them.
