CT scan resolution?

Postby Utwo » Sun May 07, 2017 10:48 am

I understand that new CT scan machines have better resolution.

How important is such difference?

In practice, do you pay any attention to CT scan machine model/generation when scheduling a CT scan?
58 yo male at diagnosis: T1bN0M0, 0/15 nodes, low grade/moderately differentiated adenocarcinoma
03/2016 colonoscopy: 2 small polyps removed in left colon; CEA = 1.3
04/2016 colonoscopy: caecum sessile 3.5 cm polyp piecemeal removed with kind of clear margins
05/2016 "prophylactic" laparoscopic right hemicolectomy - bleeding, leak, infection
06/2017 CT scan, colonoscopy OK; CEA = 1.6
A lot of funny stuff discovered by CT scans in liver, kidney, lungs, arteries, gallbladder, lymph node, pancreas

When you are in "maintenance mode" from a cancer diagnoses, CT are used to monitor you. Yes you want the best they have out there. If there is a met spread or a recurrence, early detection is the key to putting you back in NEDville.

Not sure if I answered your question.

I don't ask the model when scheduling for a CT. Where I go, that is all they do, they tend to be up on the latest, newest machines out there.

Hope this helped,

In a very general nutshell :
newer model CT scanners = higher tech = lower exposure = better resolutions
in general... BUTT nothing is ever really simple and the devil is always in the details.
It will depend upon area of study, type of study, contrast or non-contrast etc.

Did I go CT scanner info "shopping " ? = yes
why get a low res high exposure CT when you can get a high res low exposure one ... for the exact same purpose ?

NOTE : I have VERY good / responsive / pro-active doctors now. I ask the tough questions and they give me the straight goods.
I am pretty much past the normal doctor patient relationship, 'cos they have figured out I know as much as they do
and sometimes more about my specific condition, except for the minutiae / details of their own specialties.
I kind of drive my own health care bus now.

Best wishes
ask the tough questions !

While I am far from being "medical smart" there have been a few times when I know certain doctors are a bit behind the times. Have told me things that sorry, I know better. Yet I have other doctors if they tell me to do something, I'm on it.

Yes it IS a long and winding road we travel my friend .....AND best not to do it alone ...
OR try to be your own doctor per se BUTT we do need to be vigilant, pro-active and ask the right questions.

(( my own theory embodied in a phrase which I believe I made up somewhere somehow ?? ... :shock:
"any idiot can get the right answer, given enough time and resources.
The real GENIUS is in asking the RIGHT QUESTION in the first place !" ))

While it is essential to me, to be in the medical "know" ...
I still search out "my experts", engage with them and ultimately let them do their jobs as experts without trying to second guess / question and get in their way ... ONCE the decision has been made for a certain course of action, for the right reasons.

Sometimes we just gotta Own it !
It is our Journey after all .... JMO ! :mrgreen:
