The image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more

What does 'diffuse severe attenuation of the left vertebral artery" mean on a neck ct scan with contrast? Could it be cause of previous spontaneous arterial brachial clot or subclavian clot?

What does 'diffuse severe attenuation of the left vertebral artery" mean on a neck ct scan with contrast? Could it be cause of previous spontaneous arterial brachial clot or subclavian clot?

Hard to: Say with certainty without access to the images and report, but most commonly this is simply due to a developmental/congenital anatomic variation whereby one vertebral artery is very small. This would not be the cause of a clot elsewhere. ...Read more

I recently had a Head and Neck CT scan. One without and one with contrast. What are the chances a brain tumor causing symptoms was missed?

I recently had a Head and Neck CT scan. One without and one with contrast. What are the chances a brain tumor causing symptoms was missed?

Very remote: CT scan will pick up a brain tumor easily although it is not the best test for small (tiny) tumors. But then you would not have any symptoms from a small lesion. Please share information about your symptoms with us....we like to have detailed history of what is bothering you to start with. ...Read more

What is lemierre's syndrome? My neck CT scan shows this says clinical concern for lemierre's syndrome.

Lemierre's syndrome: Lemierre's syndrome refers to infected clot in your veins. It affects young, healthy adults and develops most often after a sore throat caused by some bacteria of the streptococcus genus has created a peritonsillar abscess. The bacteria penetrate into the neighboring jugular vein in the neck and there they cause an infected clot which can break off and cause an infected pulmonary embolus. ...Read more

I've had a neck ct scan and four x-rays and a hida scan? I'm worried about the radiation exposure... Should I? All in the past year, I'm a 34yr F.

CT scan; not the Xra: CT scans involve ~400 times more radiation exposure as Xrays, & so if u worry abt unnecessary radiation risk, limit CT scans. HIDA & Xrays involve so little radiation that u prob got as much from walking outside in 1 yr as u got from those tests. At 34, most of ur organs have developed, so there's no immediate threat; however, there's a lifetime radiation limit. Too much testng will catch up [email protected] ...Read more

Severe headache, blurry vision, stiff neck. Ct scan normal. ER doc felt confident. Could A CT scan have missed a cavernous sinus thrombosis?

Severe headache, blurry vision, stiff neck. Ct scan normal. ER doc felt confident. Could A CT scan have missed a cavernous sinus thrombosis?

It depends: On the technical parameters of the scan. If it was performed without IV contrast or performed as a "routine" head CT not specifically tailored to look for cavernous sinus thrombosis, yes. CST is a clinical diagnosis, so if there was no clinical suspicion, there would be no reason to tailor the CT scan. ...Read more

Can a CT scan of the neck without contrast give meaningful information on a lump? I am breastfeeding.

Yes: It can definitely help. A ct with contrast is better. If you're worried about breast feeding with the contrast, its not an issue. The amount that is actually eventually absorbed by the baby from the stomach is extremely small. Much less than we give babies actually getting a ct scan. ...Read more

My doctor ordered a CT scan with contrast. I am on thyroid meds and worried about the dye/contrast. What can I do?

My doctor ordered a CT scan with contrast. I am on thyroid meds and worried about the dye/contrast. What can I do?

No worries: There is not a concern, if the ct is evaluating other parts of your body, including the neck. The contrast will not cause a problem with your thyroid or your medications. But, you don't want to do this type of ct scan, if your doctor later plans on evaluating the thyroid itself with a radioactive uptake nuclear medicine scan because it can interfere with that and skew the results. ...Read more

Can chest CT scan puts me at the higher risk of thyroid cancer? Chest CT was done with contrast. Can contrast used in chest CT damage thyroid?

Can chest CT scan puts me at the higher risk of thyroid cancer? Chest CT was done with contrast. Can contrast used in chest CT damage thyroid?

Yes, no: There is some evidence that chest ct could put one at higher risk for thyroid cancer - but almost all of these suggest that it is dose dependent and that it would take repeated scans/exposure to elevate the risk. You can request protective covering for thyroid if need additional scans. The contrast used will not cause thyroid damage or disease. ...Read more

I got an contrast CT Scan (IV Injected) day before yesterday and today I have sore throat and couple of rashes in my mouth. What should I do?

Seasonal flu: Your symptoms described above has nothing to do with your CT scan or the IV contrast. Seasonal flu is very common viral infection. Usually the condition resolves on its own with home care. Drink water and get a good rest. NSAIDs (e.g.Aleve) are also recommended every 6 hours. If concerned, see your PCP for reevaluation. ...Read more

If a head & neck CT with contrast didn't show anything 6 months ago, what is the likelihood it would now? Still having pain and still no diagnosis.

If a head & neck CT with contrast didn't show anything 6 months ago, what is the likelihood it would now? Still having pain and still no diagnosis.

Unlikely: Repeating a head CT would probably not show anything different if it was clear 6 mos ago. If the pain is severe your doctors might want to consider MRI which shows the soft tissue of the brain better than CT and gives you no radiation exposure. I hope you get some relief soon. ...Read more

Will a head and neck CT with contrast rule out a tumor? Reason I had it is constant head and neck pain on left side X6months. Normal results.

It will rule: Out a neck mass with a relatively high degree of confidence, but no test is 100%. It is likely enough to start thinking of other etiologies for your pain rather than a neck tumor, unless there is a palpable mass, in which case additional imaging may be warranted. ...Read more
