Do ovarian tumors show up on an abdominal/ pelvic cat scan with contrast?

Do ovarian tumors show up on an abdominal/ pelvic cat scan with contrast?

Yes if big enough: They can be seen if over 2cm. Transvaginal sono is more sensitive. Neither method has been shown to be a useful screening modality for ovarian cancer. ...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

How accurate are CT scans for brain tumors?

How accurate are CT scans for brain tumors?

VARIABLE: Ct scans can often detect an abnormality. Use of contrast will identify additional lesions. However, use of MRI scanning with and without contrast can often more clearly show a brain tumor. ...Read more

I had a CT scan that showed a fat filled ovarian dermoid cyst & the vaginal us said it was fluid filled. Which one is accurate?

I had a CT scan that showed a fat filled ovarian dermoid cyst & the vaginal us said it was fluid filled. Which one is accurate?

Probably CT scan: Generally speaking, the ultrasound is a better study for the gyn structures. However, my personal experience is that the ct scan is better at picking up acute inflammatory processes such as these. ...Read more

If I had a cat scan when I was 20 and it show no tumors etc would I need another one? how accurate are cat scans

If I had a cat scan when I was 20 and it show no tumors etc would I need another one? how accurate are cat scans

May or may not: CAT scan is very accurate to detect any growths inside our body but it will only pick up growths that are 1cm or larger. The only reason to do a CT scan would be if you have any indication /symptoms that make tumor is a possible cause. Your doctor will need to check you first and determine if the CAT is needed or not indicated if you have NO symptoms. ...Read more

Do CT scans see brain tumors?

Do CT scans see brain tumors?

They can: The diagnostic yield of increased with use of IV contrast material as some tumors disrupt the so called blood brain barrier affording the contrast the ability to infiltrate from the blood stream into the tumor. Small tumors that have not disrupted the integrity of blood vessels may escape detection on CT especially if the have the same radiographic tissue density as their surrounding tissue. ...Read more

Can you tell me if CT scans usually pick up tumors?

Can you tell me if CT scans usually pick up tumors?

Yes they do: Ct scans are one of the best means of detecting abnormal growths such as tumors in the human body. But only a specialist can guide you as to what kind of ct scan is required for proper imaging. In some body sites MRI scans are more useful than a ct scan. ...Read more

Do ct scans with no contrast always miss tumors in the cerebellum?

Do ct scans with no contrast always miss tumors in the cerebellum?

Not always: Brain CT scans without contrast do not always miss cerebellar tumors. A tumor whose density is different from that of its adjacent brain tissue, or whose size is such that it pushes away adjacent brain tissue (distorting the normal shapes and outlines) will likely be visible even on noncontrast scans. ...Read more

I was diagnosed with carcinoid syndrome in march of 2007. I have had yearly CT scans since then, and no tumor has been found. Is this common?

I was diagnosed with carcinoid syndrome in march of 2007. I have had yearly CT scans since then, and no tumor has been found. Is this common?

Not uncommon: Carcinoid is a type of tumor that usually arises within the gut wall. Though larger tumors can often be seen on ct scans, it is not unusual for a small carcinoid to be difficult to see on ct (especially if it arises in the small bowel). If the carcinoid is aggressive or spreads, ct is likely to see it. A radionuclide test (e.g. Octreoscan) is a useful adjunct when ct does not detect the tumor. ...Read more

Has it ever been proven that CT scans of the brain cause tumors?

Has it ever been proven that CT scans of the brain cause tumors?

Read more about it: To learn more about imaging and radiation, see: http://www.Conciergeradiologist.Com/ct-scan-radiation.Html and http://www.Conciergeradiologist.Com/radiation-exposure.Html. Properly indicated imaging studies represent, by definition, situations where the risks of radiation are outweighed by the benefits to the patient. I wouldn't worry about ct scan radiation causing a brain tumor. ...Read more
