Can a CT scan of the abdomen/pelvis without contrast detect colon cancer and ulcers?

Can a CT scan of the abdomen/pelvis without contrast detect colon cancer and ulcers?

CT Scan Findings: Ct scan is not the best study to detect colon cancer or ulcers. Although a ct scan may show a large sized colon cancer, the sensitivity of this is greatly reduced without the administration of oral contrast. Ulcers are typically not seen on ct scan. The best diagnostic study for both of these would be an endoscopy and colonoscopy.

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

Would CT scan of chest abdomen and pelvis with contrast help diagnosis of celiac disease?

Would CT scan of chest abdomen and pelvis with contrast help diagnosis of celiac disease?

Doubt it: If any irregularities in the intestinal wall were found, it would be just that, irregularities. Their presence would suggest a problem but the overlap with other possible conditions would make the information inconclusive. A normal study would also not rule out the condition.

I'm having a CT scan done of my abdomen and pelvis done this week to see if a hernia has come back, why do I need to drink two bottles of contrast?

I'm having a CT scan done of my abdomen and pelvis done this week to see if a hernia has come back, why do I need to drink two bottles of contrast?

2 See Ur Intestine: A ct of the abdomen can be very helpful for diagnosing recurrent hernias. An important part of the study is to look at the intestine relative to the hernia. Contrast in the intestine makes the interpretation of these films much easier.

I have recently had a CT scan of abdomen and pelvis - no diseases.... Can I feel secure now or is a CT scan not that specific?

I have recently had a CT scan of abdomen and pelvis - no diseases.... Can I feel secure now or is a CT scan not that specific?

Usually: Today ct scans are quite reliable for most of the really bad things that can be a problem (they can be ruled out). However you should see a dr to correlate your symptoms with your ct findings for the best assessment and recommendations.

Is one CT scan of abdomen and pelvis likely to cause cancer?

Is one CT scan of abdomen and pelvis likely to cause cancer?

Not usually one: Radiation dose from ct is about 100 times chest x-ray. However the exact number of scans to induce cancer is not precisely known. If ct is necessary for diagnosis it is very accurate tool. Most institutions have reduced amount of exposure in recent years. If same diagnosis can be made with mr or ultrasound, non ionizing radiation, they should be chosen. Certain medical problems ct is necessary.

What is a CT scan of the chest/abdomen/ and pelvis normally looking for?

What is a CT scan of the chest/abdomen/ and pelvis normally looking for?

Need more info.: Trauma, infection and malignancy (cancer) are the most common reasons to do all three at the same time. Doing the test doesn't mean you have the diseases, but the doctors are usually concerned about those three things when they order that set of tests.

How long does it take to evaluate CT scan of chest abdomen and pelvis and make a diagnosis?

How long does it take to evaluate CT scan of chest abdomen and pelvis and make a diagnosis?

Variable: The actual reading time for a ct depends on how complicated the findings are, but around 20-30 minutes. However, the imaging center may perform many many scans per day, so it may take a while before your study is read. Turn around time for a routine exam is usually a day or two. Again, this varies from one imaging center to the next. The report is then sent to the doctor that ordered the ct.

Would a CT scan of the chest abdomen and pelvis see something wrong with the gallbladder? And would it se gallstones present or previous? Had normal CT scan 2 weeks ago but I have bad pain right there

Would a CT scan of the chest abdomen and pelvis see something wrong with the gallbladder? And would it se gallstones present or previous? Had normal CT scan 2 weeks ago but I have bad pain right there

Yes: A ct scan will pick up most gallstones as well as thickening and swelling of the gallbladder and bile ducts. The only thing a ct scan does a lousy job with is detecting if the gallbladder has a hard time emptying bile. This can cause pain as well. You need a hida scan to detect this.

My CT scan of the abdomen and pelvis showed sclerosis on both sides of the SI joints, indicating sacroiltis. Is this indicative of multiple sclerosis?

My CT scan of the abdomen and pelvis showed sclerosis on both sides of the SI joints, indicating sacroiltis. Is this indicative of multiple sclerosis?

Of course not: "Sclerosis" is a general term that refers to pathological hardening of tissue due especially to calcification or overgrowth of fibrous tissue. In the CNS, where there is no fibrous tissue, it refers to an analogous process of tissue degeneration. Multiple sclerosis by definition occurs only in the CNS, not in joints. This sort of information is readily obtainable from a quick web search.

Hypothetically if somebody had melanoma on their lower back and had a CAT Scan of abdomen and pelvis 4 other reasons. Would melanoma show up on CAT?

It could: Potentially show up on an abdomen/pelvis CT, depending on the size. There are no specific features of melanoma on CT, so, if small, it would look the same as the myriad of benign nevi, keratoses, cysts, etc... that are so common, and might not be mentioned as a relevant finding in the report.

What does a cat scan image of the abdomen and pelvis reveal?

A CAT scan: With contrast provides 3d slices of all of the organs, today every 3mm, and these can be reconstructed to provide coronal (front to back) and saggital (right to left from the side) views. These were developed 40 years ago and incredibly changed medicine.

Could you give me any information about what my cat scan image of the abdomen and pelvis reveal?

Need to see: Since there was no way to look at the scan, can't really say what it saw. Plus why did you have it. Best thing is sit down with your doctor. Have a heart to heart to get the answers

Can 2 CT scans with contrast miss anything wrong in the abdomen and pelvis?

Yes: Every test has limitations. The ct scans may not have found the problem, but they have likely eliminated some possibilities. If you have had 2 ct scans and the symptoms persist, follow up with you doctor to determine if any other tests are needed.

He has already had the Ct scan c contrast of abdomen+pelvis and it was normal. And a cystoscopy and it looked fine. And dr. Just c him in 6mos.

NO problem mentioned: AS you have mentioned no problem, one might assume there was a concern for some type of tumor. If the doctor has said to resee in 6 month I would follow the advice. Best wishes.

Can a CT scan contrast cause abdomen pain and back pain all day long. My husband had a scan for abd nd pelvis. Havin this pain the preceding day.

Can.: Oral contrast can cause constipation which could lead to those symptoms. Should resolve with time as long as the CT did not demonstrate something that could interfere. Can use a laxative if necessary and not contraindicated.

Ct Scan (Definition)

Ct scan uses data from a beam of xrays and reconstructs a cross sectional image of your body. It is a high dose of xrays and used only when the benefits outweigh the risk. Cancer risk is 1 in 500 in children. Also using iodinated contrast might cause transient renal failure in about 5% of patients. (contrast induced nepropathy) most do not explain this to the patient as ...Read more
