Howard, there are a couple of Letters to New York Times and Wall Street Journal on this exact topic at   www.sepp.org/weekwas/2004/Sept.18htm   or you can do a search on my name and find other material.  John Jacobus is quoting party line, and it was party line which caused Nancy Greene's untimely death (I had her scheduled for a full-body scan in 2002 and her physicist friends in AFIO talked her out of it--until she finally became symptomatic nearly a year later, and the cancer had already spread beyond the bladder).  It is a red herring and really fishy to claim that the only motivation and justification to do CT screening is to make money for imaging radiologists.  That was the best money I ever spent, and now I can't get a followup scan because the screening CT clinic is closed.  Radiologists and Health Physicists are a PARADOX (MD+PhD) because they claim they are following PRIMUM NON NOCERE with their timid party line, and by that very act they are causing harm thru omission of
 low-level screening.  Please transmit my views to Dr. K.S.Parthasarathy and anyone else you think might be educable.  Gerry

Gerry,

Do you have professionl comment about CT screening for this health physicist list?

Dr. Parthasarathy,

I guess it is nice to see that India is becoming a
rich country where people can afford to buy into the
commericalization of medicine for profit. The
advertisement you posted is very similar to what we
had in this country.

My impression is that the "boutique" clinic phenomenon
has passed. I live in the Washington/Maryland area,
and I have not heard a radio advertisement or seen a
newspaper advertisement in the last few years. 
However, I am not sure what the story is in California
or orther parts of the country. As you note, our FDA
and professional societies spoke out against 
this
program. May be they had an affect. Or people
realized that it was not worth the expense.

Regarding your questions:

"1. Has this clinical tool reached a stage now where
it can be used routinely to diagnose symptomless
patients."

First, I am assuming that you are referring to the use
of CT scanners. Yes, it is possible for CT scanners
to diagnose asymtomatic patients. Generally, what
happens is that a finding is made when a study is
being performed for another reason. However, the
issue is the applicaiton of radiation for an intended
purpose rather than as a screening tool for
asymptomatic individuals. Prior to the 1960s, mobile
x-ray units were used to screen for tuberculosis prior
to the current skin testing process. For last several
years, screening mammography has been used to detect
occult breast cancers. There are values in mass
screening. However, I do not see self-referral as
being in this category. 
The problem is that if a
suspect finding is identified, the customer will want
followup medical studies. (If your have ever read a
radiologist's report, it is an list of "could be" and
"likely." Beyond the evalution of the suspected
condition, they write down everything they see.) This
puts a drain on health resources, for both the
individual and the public health care programs. In
one case, all reports of "suspecious liver" were found
to be negative after further tests that cost time and
money. It is important to also remember that some
conditions do not require treatment. There are many
80-year-old men who die with untreated, undiagnosted
prostate cancers that did not causer the death or
affect the life of the individual.

As noted at the CDRH web site
http://www.fda.gov/cdrh/ct/
"At this time the FDA knows of no data demonstrating
that whole-body CT screening is effective in detecting
any particular disease early enough 
for the disease to
be managed, treated, or cured and advantageously spare
a person at least some of the detriment associated
with serious illness or premature death."

2. Many professional associations including The
American Heart Association, American College of
Radiology, HPS and AAPM are against using CT on
asymptomatic patients. US FDA has also advised
physicians against such over use. The professional
associations in India are not taking a stand 

As I noted above, many of our governmental and
professional organizations did come out against CT
screening. The position of the FDA was well
publicized. Whether they had any impact on the
decline of CT scanning, I do not know. 

I should mention for clarity that I am not a doctor,
medical or academic. I would like to get a PhD, but
only time will tell.
