Can ct head/orbit cause : lightheaded dizzy  w/ brief low rumble noise , headache w/ tingling forehead? Dr said maybe anxiety, but no hx panic.attacks

No, a CT cannot: CAUSE these symptoms. In fact, a CT may HELP DIAGNOSE reasons for dizziness and headache, such as sinusitis. Your doctor is correct that anxiety can cause dizziness and tingling, even without "panic attacks". If you have your CT on a disc, I can explain it to you on HealthTap Concierge healthtap.com/saurbornmd. ...Read more

The table moves as the xray tube and detectors spin around the patient 10 times a second or more! 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

Had ct of head with and without contrast for HA. Results show small cyst and recommend MRI. Should I be concerned?

Had ct of head with and without contrast for HA. Results show small cyst and recommend MRI. Should I be concerned?

Not without symptoms: If you are not having symptoms, I don't think you even need an MRI. It's just wasting time & money going after an incidental finding. Most brain cysts are benign. If they were expanding, you would have neurologic symptoms (headache, vision probs). What prompted the MRI in the 1st place? Discuss with your primary doc or use HealthTap Prime to get advice from someone who knows your medical history. ...Read more

What does CT scan of head without contrast show?

What does CT scan of head without contrast show?

Many things.: It can detect many conditions. Ct is particulaly good at detecting bleeding in the acute setting and hydrocephalus, and some masses. It's not nearly as good as MRI for looking at small structures and white matter disease. Both ct and MRI are usually more sensetive and specific when contrast is given. ...Read more

Does the head CT scan with and without contrast i got affect my ability to have children in future ?Does it mean that i can't marry now ? Im only 26yr

No Worries: The radiation from 1 head ct does not measurably increase your risk of cancer in the future. The radiation was no where near your testicles, and even if it was, there is no measurable risk for birth defects in children. Finally, the contrast was eliminated from your body within 24 hours, assuming no kidney problems. ...Read more

If a head CT scan with and without contrast ruled out brain tumor can I be sure that i don't have a brain tumor?

Why do you worry?: Cat scan is adequate to demonstrate even a modest size lesion, and seems reassuring. Yet, you remain focused and perhaps doubtful. Urge you contact a counselor and explore the underlying causes of your persistent concerns. Actually brain tumors are quite uncommon. ...Read more

2 years and 3 months ago i got a head CT with and without contrast im now getting a mild headache can that be brain tumor caused by the CT radiation ?

No: First off, the amount of radiation from a head ct is very small. Less than the smiunt you get from the sun and cosmic rays in 1 year. Secondly, even if it were to cause that, it would take many many years. ...Read more

What would a CT head scan show versus having a MRI head scan? And with or without contrast?

What would a CT head scan show versus having a MRI head scan? And with or without contrast?

Need to talk with : Your ordering doctor. Depends on what is being evaluated, and the differential diagnosis. Ct is a good quick screen for bleed, masses, skull fractures, etc. And MRI gets you good soft tissue details, and lets you better evaluate the gray and white matter, also allows you to evaluate bleeds, helps you tell if old or new bleed, also helps you see tumors, strokes (ischemic areas, atrophy, etc.). ...Read more

What to do if I had a non-contrast CT head scan in march of this year. if What to do if I had pontine glioma would it have been detected?

Pontine glioma: This region is subject to a lot of artifact from the bony skull base on CT. Also, the lack of IV contrast significantly limits the sensitivity of CT to visualize tumors, especially small tumors. I can't say without looking at the images whether the pontine glioma was visible, but, particularly if it is small, it would not surprise me if it was very difficult, or even impossible, to see. ...Read more

Intermit daily head pain on top-back right side.  dull.  CT head  w/w/o contrast- Norm.  Scalp seems sore in the area when pressed.  No other sympts?

Possibly MFPD: If you clench your teeth or even grind(brux) at night when sleeping, the entire side of your head can ache/throb. There are muscles under the scalp that can hurt when pressed like you describe when they are inflamed from this(Temporalis). Dentists are generally good at identifying this(MFPD=myofacial pain dysfunction). It's not a dangerous condition, but depressing and painful. ...Read more
