Sir I have a question.I had done ct scan of neck and thorax plain andd contrast. Is this kindd of scan is same as ct angiogram. Please reply

[@HowRadiologyWorks]

Hi, sorry we don’t answer questions related to personal scans but in general a CT angiogram is a scan taken to see the arteries and it is contrast enhanced.

Hi Sir,
I have a question regarding the pressure limit.
Is it true that the purpose if pressure limit is to prevent the syringe and coil from exploding and doesn't really do much to prevent extravasation.
Thank you.

patientsafety.pa.gov/ADVISORIES/Pages/200812_136.aspx , yeah a major reason for the limit is to prevent tubing issues

Question,
I had a CT cardiac angiogram. When the contrast was injected, my heart beat went up over 100 bpm because it burned like hell , especially in my head and groin area.
This ruined the image. They like you to have a low bpm between 50 to 65 bpm to get a good image.
How can this high bpm be avoided after the contrast injection? I was given a gts tablet and beta blocker.

I’m sorry that you had a hard experience on your exam. Sorry we don’t offer medical advice on this station for specific issues.

unlike antibiotics and other medications injected Intravenously, contrasts used in CT scans do not cause pain itself when injected.
some factors that might have caused you the pain includes a lot of factors like the quality of the vein your IV access is put, location of the vein your access is put, the skill the person who did your access, the quality of how the access is set up, temperature of the contrast (it is generally recommended to be injected on the same temperature of the body before injection to keep it less viscous than it is when it is cold)
also,
most often contrast injection on Cardiac CTs is not painful, although a patient will definitely feel a sensation from the injection since contrast on these types of scans are injected faster than other more general type of contrast procedures.
if you say your heartbeat spiked during the time you were in pain. then being more comfortable during your next scan might be a solution. you can always communicate to your technologists or doctors or nurses involved in the scanning.
medication wise online prescriptions from a non medical regulated platform is not a good idea
