What Happens During a CT Lung Scan?

Computed tomography (CT) uses X-rays and computer technology to produce comprehensive images of your lungs. It can provide a much more detailed picture than regular X-rays and can identify conditions like lung cancer, infection, or other lung problems. See what happens during this exam.

I’m getting a CT scan tomorrow morning (my first ever) to check on a strange feeling in my upper chest… this video helped me have an idea of what to expect. Thank you… and fingers crossed for positive results! 🤞🏻🙏🏻

Thank you. Just turned 72 on June 1st. I'm getting my first cat scan tomorrow at 9. I'm a little worried. I just quit smoking on February 2nd. I started at 17 years old. Saying a prayer. 😢

Are we expected to sign an informed consent form prior to the scan? If yes, can we obtain form(s) in advance through mail, email, or download?

@MayfairDiagnosticsOfficial 7 ай бұрын

Hi @comprehensive_offical, thank you for your question and I apologize for the late reply. If you don't need contrast, there is no consent form. If you do need contrast, we can email you the form at the time of booking. You will need to ask the booking agent to sent it to you. I hope this helps.

I am super claustrophobic. i am having a cat scan of my thymus gland in my chest area. I need to know if the images would show my lungs clearly as well if it's a non contrast cat scan. i have had a nodule in my lung for 10 years. so it's something that would be eventually ordered. i would like to use the same images for 2 different doctors( one that wants to see my thymus gland and other other that wants to see my lungs) that way i don't have to sit through another ct scan.

Hi @readingchapterbooks881, thank you for your question. Lungs can be seen without IV contrast, as can the nodule. However, without IV contrast, all anatomy will have a generalized shade of grey and may hide abnormalities. If the nodule is greater than 1cm, it’s recommended that we use IV contrast to see if the nodule enhances (has blood supply). Without contrast, larger nodules can appear benign, but may not be. The thymus gland is also something that would benefit from contrast. I hope this helps. You can email us at patientservices@radiology.ca if you have further questions. Thank you.

What if you have an intermittent cough, or if you cough *because* you’re holding your breath?

@MayfairDiagnosticsOfficial 8 ай бұрын

Hi @generic_official, the breath hold is less than 10 sec so all we ask is that you try your best. The technologist will work with you to make sure you're comfortable.

During the actual scan do you have to keep your eyes closed? I opened my eyes a couple of times during CT THORAX AND ABDOMEN because I am claustrophobic. Could I have damaged my eyes?

Hi @harbinderk5837, no, you don't have to keep your eyes closed.

What is the risk of throwing up? I have a phobia and I’m worried the contrast will make me sick

@MayfairDiagnosticsOfficial 6 ай бұрын

Hi @ljtravels3861, with a routine lung scan, with IV, we have never seen it happen if that helps ease your concerns. There is a 'warm feeling' described by patients when they receive it, but no one has thrown up. Hope this helps!

If the patient smokes is that a problem for this MRI to be done?

@MayfairDiagnosticsOfficial 9 ай бұрын

Hi @VSS32542, no, it would not be a problem to perform this exam if the patient smokes. Please let me know if you have any more questions.

@VSS32542 9 ай бұрын

@mayfairdiagnostics7927 thank you for your response a little late but the MRI went well.

What happens if you are diabetic and on plavix ? Is that a blood thinner?

@MayfairDiagnosticsOfficial 6 ай бұрын

Hi @katherinegosnell8256, thank you for your question. Diabetic patients or those on medications can have CT scans, even if we require the use of IV contrast. If this doesn't answer your question, please email us at patientservices@radiology.ca and we can speak about this in more detail.

Little, if anything, is said about radiation exposure from a CT scan and what exactly is in the contrast dye solution? How long will that dye substance remain in a person’s system? As I understand it, CTs use ionizing radiation, which is not good for a person’s DNA. Lots of radiation exposure?

@MayfairDiagnosticsOfficial 3 ай бұрын

Hi @sarahmccoy1941, radiation dose is strictly dependent on the patient's body habitus, and the exam we're performing. If a person was having a CT chest, abdomen and pelvis, an average person would expect to receive approx 3-4 mSv which is quite close to the amount of radiation someone living in Calgary at our altitude receives every year. Lower elevation - less radiation. Higher elevation - more radiation. The CT dye is an iodine based solution which shows up as white on the scan - enhancing the arteries/veins/ organs. Radiation is NOT good for anyone - however, it's our understanding that in one's lifetime, the risk of getting cancer is approx 20%. After a CT scan (eg. chest, abdomen, pelvis) the risk of getting cancer would now be approx 20.1%. Depending on what the referring doctor is looking for (eg cancer) the risks from radiation far outweigh the risk of missing disease. We also have dose reduction software that we use for all of our scans. Some exams (virtual colon) allow us to use a higher dose reduction than other exams where we may need higher detail. Ultimately - if there is any concern about radiation - please speak to your doctor and perhaps there's another Diagnostic Imaging exam type you can have done instead. Hope this helps! Have a wonderful day.

What will happen if you swallow during CT SCAN contrast?

@MayfairDiagnosticsOfficial 3 ай бұрын

Hi @kimatencio6935, nothing will happen - unless of course we're specifically scanning the throat and esophagus - in which case there will be motion on the scan. I hope this helps with your question. Please let me know if you have any more. Have a good day!

What if the patient can't hold breath for few seconds?

@MayfairDiagnosticsOfficial Жыл бұрын

Hi @chickencairontamiyaapolina4633, the breath hold is less than 10 sec so it really shouldn't be an issue. If they can't hold their breath - there will likely be some motion on the images - which could blur the anatomy - and any pathology, making the report less than accurate.

Can you have hair loss with this CT scan?

@MayfairDiagnosticsOfficial 8 ай бұрын

Hi @harbinderk5837 - No, the average dose for a CT chest is usually 3mSv or less (the lung screen is much much less) - you would need a dose as high as 1000-5000 mSv to produce localized hair loss. I hope this helps with your inquiry! Have a good day.
