Dec. 21, 2009 - Patients Urged to Weigh CT Scan Risks and Benefits
CHICAGO (Reuters) - Patients should not let recent studies
showing that exposure to radiation from a CT scan may raise their cancer risk
scare them away from getting this type of X-ray when it is needed, radiology
specialists said on Air
Jordan 7 Tuesday.
A CT scan, also known as computed tomography, gives doctors a view
inside the body, often eliminating the need for exploratory surgery. But CT
scans involve a much higher radiation dose than conventional X-rays. A chest CT
scan exposes the patient to more than 100 times the radiation dose of a typical
chest X-ray.
Radiology specialists emphasized that an individual's risk
of developing cancer as a result of radiation exposure from a single CT scan is
very low, especially when compared to the risk to them from a disease that a CT
scan may help identify.
Use of these tests for detecting tumors and heart disease
and diagnosing other conditions such as appendicitis has risen dramatically in
the past three decades.
Dr. Elliot Fishman, a professor of radiology at Johns Hopkins
University in Baltimore, said some studies equated the risk
of getting cancer from a single CT scan to the risks of dying in a long car
ride.
"If you are going to a good physician who orders a
study (a CT scan) that he or she thinks you need, you need to get the
study," Fishman said in a telephone interview.
Recently published research has raised concerns about the
risks of radiation exposure from diagnostic tests, especially CT scans. Two
studies appearing on Monday in the Archives of Internal Medicine estimated that
CT scans cause thousands Air Jordan 8 of U.S. cancer cases and cancer deaths
each year.
The estimates of cancer cases caused by CT scans were based
on the rates of cancer that occurred in people exposed to radiation from the
atomic bombs dropped on the Japanese cities of Hiroshima
and Nagasaki at
the end of World War Two. But many experts disagree on whether that model
offers a fair comparison.
