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

Computed Tomography (Definition)

Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. 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

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

Had 2 CT head scans without contrast in 2 months. 29 yo. Could this cause thyroid cancer? Is thyroid exposed during scan? Tech said no. Beg to differ.

Had 2 CT head scans without contrast in 2 months. 29 yo. Could this cause thyroid cancer? Is thyroid exposed during scan? Tech said no. Beg to differ.

No worries: A couple of head CT scans does not cause brain cancer, eye cancer, nose cancer, throat cancer, ear cancer, neck cancer, thyroid cancer, or any other cancer. No worries. That said, a head CT is sometimes used to look for a cancer tumor. That means although a head CT does not cause cancer, the scan can cause you to find the cancer you were looking for, if you were suspecting and looking for a tumor. ...Read more

Ct of head w/o contrast in aug 2012. Mri with and w/o contrast in february 2013. If I had another MRI this month, is this too much radiation?

MRI: Mri aren't using ionizing radiation so don't have the radiation risks of other imaging like x-rays and cts. You'd still want to be sure that the MRI is needed, and discuss with the ordering physician what information is hoped to be gained from a repeat imaging procedure. ...Read more

Ct of head ystrdy showed sm hole up lft. Doc said indicative of brain cancer. Said it'd be bad if it hasn't always been there. Then left! Next step?

MRI to better: Evaluate. Ct is a good first step, but a contrast enhanced MRI provides much more information about the degree of enhancement, presence of edema, and is optimal for surgical planning if it is in fact a tumor. If tumor detected, make sure to be evaluated for treatment at a high volume academic hospital as outcomes are tied to experience. ...Read more
