CT scans hurt infant brains
"Researchers in Sweden say they have uncovered evidence that
the scans may damage toddlers' brains. Their study of more than 3,000
men who had scans before they were 18 months old found many went
on to develop learning problems." This
is of concern.
Ionizing radiation, as in CT scans, mammography, and xrays are
known to be damaging to DNA and ultimately to cell function. This
may lead to a radiation induced cancer, or more subtle
problems (as in this article) like learning difficulties. Unfortunately
there is usually a long time lag between the initial incident
and the measurable outcome that make the damage difficult to quantitate. The
doctors dilemma is always what is the risk reward ratio of doing
the diagnostic procedure. Will the information gained be of more
benefit than the side effects of learning disabilities or
cancer. Practically, with the number of lawyers hungry for
work, and the generous settlements to plaintiffs, the doctor
is always inclined to do the test to protect himself against a possible
malpractice action. The "do no harm" axiom gets layed aside and
replaced by "do what it takes so no harm comes to me from a litigious
patient." Awkward ethics for the healthcare practitioner especially
since the vast majority of the time the tests are negative.
We must not forget that modern medicine is no free lunch. The
best decision occurs when a very good doctor and an informed
patient,make the right decision for the short and long term benefit
of the patient. -
