That was fun! I have no medical training - but got 99% right on the contrast/no contrast “quiz”! Stupid pride, I know…but I needed a little lift to my ego today - and this helped!💕
@@Hospitalista Yes Thanks. The problem is, I'm not being followed by a specific doctor, in fact, the doctor who prescribed the various CT scans I don't even get to talk to. I can deny doing the exams but I would like to do them, I just wanted to understand wether it would be worth it, meaning wether they'd still be useful for the doctors. In my opinion if it serves for nothing a CT scan without contrast, they shouldn't even allow us to do it! Thanks anyway
I'm trying to figure out what kinds of CT scans i got while i was in the hospital for sepsis and bacterial endocarditis. 2 weeks before i was admitted i had a head scan to check for bleeding because i kept getting worse after an unrelated concussion. Im not even sure which ones were CT or MRI, and i only remember having the contrast stuff once. And i think that was for a back MRI to check if the infection had spread to my back. I remember having 3 CT scans and one MRI.. I hope at least 1 was low dose because it's an absolutely massive dose of radiation to recieve in a 2 month timespan..
I am sorry I can’t give any specific clinical advice on this platform, please follow your doctor recommendations. In general we don’t use oral contrast for vocal cords issues.
I got a non contrast CT scan done at the ER 2 months ago for left sided weakness... Apperantly nothing was wrong but my health anxiety tells me they missed a brain tumor. What are the odds of them missing it?

video is excellent but I want to ask a question you say we don't need contrast non penetran trauma and non vascular pathology okay but how can I understand patient has vascular pathology or not
Glad you liked the video, penetrating injuries can be easily recognized on physical exam including any vessel bleeding externally or if internal bleeding suspected
Thanks for reaching out! I don’t give any specific clinical advice here and you should follow your doctor advice. That’s being said CT done for tumors in general requires CT with IV contrast.
TEE is better than TTE. TEE is more invasive and therefore used if a more definitive diagnosis is required. For example, while doing a FAST examination in ED on a patient in a motor vehicle accident, you would do TTE. TEE is also done for an old A-fib if the goal is cardioversion in evaluation for leaflet pathologies. TEE is used for assessing unstable patients for thoracic aortic injury (aortic dissection) without moving them to the CT scanner.
Most providers will order it without AND with. Whether by incompetence or enthusiasm or greed, it seems they are taught that more is better. Contrast media is very expensive, also.
@@symanowrin1941 Not as bad as all that; radiation doses are not as bad as they used to be. The question is risk vs benefit which your doctor is supposed to weigh when deciding to order a scan. Just don't wait til you're on the scanner and ask the Technologist: it's a question for the doctor.
@@Hospitalista So the ionizing radiation from a CT scan is not bad of a patient? From what I understand about radiation, there is no acceptable level of ionizing radiation that is good for a person. An MRI would seem safer as it does not use radiation.
Your physician should decide if you need that kind of study or not and outweigh risk and benefits, am not sure about the exact amount of radiation but you can visit this FDA website that has a lot of information about that www.fda.gov/radiation-emitting-products/medical-x-ray-imaging/what-are-radiation-risks-ct#:~:text=for%20cancer%20mortality.-,Risk%20Estimates,survivors%20of%20the%20atomic%20bombs.
Absolutely give i.v. contrast in patients with blunt trauma to assess for lacerations, bleed, pseudoaneurysm etc. This is misleading and dangerous. Anyways, it doesnt really matter what your "order", if you write a good history and what youre looking for the radiologist will find an appropriate protocol.

Sharing so many example cases is genius! Thank you for the knowledge and the practice.
I am wondering about the injections. Allergic reactions, side effects, how does it leave the body, potential long term harm to the body etc...
IV contrast is excreted in urine by the kidneys. Renal failure is a contraindication for IV contrast.
Super helpful regarding a subject matter that is not always explicitly explained. Thank you so much!
These are excellent videos, and I am grateful for your work, but it may be that the sound effects are a little distracting. Thank you, regardless
Fantastic subjects to explain , ive enjoyed most of your videos , thanks alot
Phillips has CT machines that don't use any contrast. Just ask around to see who has them. These contrast are nephrotoxic
i like music and Buzzing and the way he is talking well done
Hi!
For those who are alergic to contrast (iodine) is it worth doing any CT scan without contrast?
This really depends on why you getting a CT? The doctor who ordered the CT should be able to answer this question better than me!

So basically. Without contrast enhancement can tell u about the tumor clearly?
Thankyou, absolutely nailed it.

How does it work ? First without than with means 2 scans
@@symanowrin1941 Yes, you get 2 scans and of course about twice the radiation and much more expense. Sometimes you need it both ways but usually not.

Do you need contrast for endometrial cancer?
In general we prefer to give contrast whenever assessing any neoplastic issue but the final decision should be up to the patient’s physician
In appeniceal mucoceal
Iv contrast should be given or oral???
Plz reply
Usually IV contrast
Thanku for reply
My Dr preferred oral...
For appendiceal mucoceal...
Any reasons
Not sure why! But am sure he has his own reasons, at the end he knows the case and what's best for that specific patient.
Will ct scan without contrast show brain tumours both large and small ones?
most likely will show larger ones, but MRI is better at this
very nice thank you for the great effort
I have read that the radiation for CT scans is not goo for the body.
This is an inaccurate general statement!
@@Hospitalista So the ionizing radiation from a CT scan is not bad of a patient?
From what I understand about radiation, there is no acceptable level of ionizing radiation that is good for a person.
An MRI would seem safer as it does not use radiation.
