Just some information for those interested in medical/health issues .
!!Keep in mind .. I am a lowly technologist and know nothing. Always Always seek advice from your health care advisor/provider..!!

With the new advent of multi slice CT(CAT) scanners (ranges from 8 to 64 slice CT scanners) , come higher radiation doses.IT is possible Some clinicians(such as family dr, and even some specialists) do not realize,or simply have not contemplated the increased radiation dose from multi slice (64 slice) CT scanners.
They are wonderful tools-CT scanners, but one needs to keep in mind the increase radiation factor of the newer multi slice machines.
If one Needs a CT , then of course go for it.
CT scans can diagnose disease, tumors,trauma etc. beautifully and are Very worthwhile..
I hear CT techs voicing concern about the exposure increase to patients with the 64 slice.
While it is not ethical/ or politic for a technologist to "educate" a dr.. doctors need to be made aware of this . We as techs must tread very lightly with drs. at times. Radiologists (drs) might hestitate to inform patients drs, as it may seem the rad is trying to countermand the pts dr. .
It is a twisted, tricky, lawsuit happy road we travel in health care now days.

One more thing to consider is MRA (magnetic resonance angiography).. it uses the MRI machine, but scans differently with a higher dose of contrast media (some call it dye).
The contrast is gadolinum (shortened name we techs use) not iodine as in CT or xray.
The FDA has issued a cautionary statement.
If a patient has renal failure or insufficiency, MRA ( higher dose of contrast) may cause some problems for the pt.
This can be found on the fda/gov website and search under MRA or gadolinium .
MRA is also a great tool , helps with diagnosis, etc.. Only people with renal (kidney ) failure, insufficiency are part of the ongoing concern . General public ,healthy renal function, need not worry according to the study.

I just wanted to bring this to your attention as I feel responsible as a tech to educate/protect patients. But .. as a tech I have to be very very careful not to cross over into dr. territory ! ethics vs egos can collide.
Keep in mind .. I am a lowly technologist and know nothing. Always Always seek advice from your health care advisor/provider..
If you are interested in radiation exposure facts, I am sure a google search would work.
I am not a radiation physicist so cannot tell you how many rads you'd get from CT chest and abdomen done with a 64 slice scanner. Multiple exams on the same patient --- increase the exposure.

Thanks for this information. I was just trying to decide which tests I will agree to tomorrow when I visit a new uro-gyn. I have had numerous ivp's and have heard radiation is cumlative but do not know if this is so or not. I am leaning toward insisting on a ultrasound only now!

See this is what makes this site so great. We get to share info with others that may make a world of difference. I have had a few MRI's and spiral CT's- so thank you. Oh and you are NOT just a "lowly" tech- you are an obviously intelligent, caring person. I used to refer to myself as JUST an LPN, since some people don't consider LPN's nurses- but I AM a nurse. So again, thank you and keep the info coming- all of us can contribute here. :friends2:

Yes radiation is cumlative over a life time. For sure folks who Need multiple exams done for a sound medical reason should have them. The higher the CT slice number, the more radiation if I did not make that clear.
I have seen cases where patients with no medical background/knowledge, force/pressure the drs to order specific tets.
And quite frankly, some drs over order IMHO.. but I am not a dr. so I cannot say what is appropriate to order etc..

You are not getting a huge amount of radiation with an IVP, or a chest xray as long as it is not done say every week for a long time. . I don;t recall the exact number of rads right now tho.

As we all know it is So important to try to educate ourselves about our health, body, medical needs. Make it a partnership with our health care provider. I won;t go to a dr. who resents my asking questions, or feels intimidated by my bit of knowledge. And I truly only know a tiny bit compared to what drs learn in med school ..

I hope this does help someone make informed decisions, and inspire others to question, and educate themselves.

Most drs. are very very concientious(sp) and desire to only help their pts.. But like with everything in life, there are the less than caring ones out there .

LPN.. definately a nurse and Very good nurses too.. I work with some who do a better job than a few RN"s I know..

Suzi --

Wonderful post, very informative.

May I take this opportunity to recommend, once again, two very good reliable sites for medical information:
