Abdominal cat scan show colon cancer?

Abdominal cat scan show colon cancer?

Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more

Can a ct scan detect liver failure in metastic colon cancer?

Can a ct scan detect liver failure in metastic colon cancer?

No: A CAT scan is used to visually define the extent of metastatic colon cancer in the liver should metastasis be present. Liver failure is a condition measured by functional abnormalities that occur within the liver usually due to parenchymal damage such as inflammation from hepatitis . Here one measures serum enzymes and the presence of elevated alkaline phosphatase and bilirubin in serum. ...Read more

Depending how used: CEA first identified in 1965 by Phil Gold and Samuel O. Freedman in human colon cancer extracts. Thought to be valuable for dx colorectal Ca but the glycoprotein is also expressed in inflamed tissue so that smoking and enema can cause rise. Best used for monitoring so that if present in primary and rises it represents treatment failure and if diminishes during treatment it represents a response. ...Read more

Do pet scans show lung cancer?

Do pet scans show lung cancer?

Sort of...: The pet scan non-specifically show very metabolically active (consuming lots of energy), and lung cancer and its metastasis fit that category. It is not specific. Benign conditions like sarcoid can also make pet studies glow very brightly as well. Slow growing lung cancer, broncheoalveolar may not be pt avid. ...Read more

Can KUB show polyps and/or colon cancer?

Can KUB show polyps and/or colon cancer?

Not usually: Polyps and Colin cancer are soft tissue conditions, and do do not typically show up on X-ray. The main exceptions to this are if they are calcified, if they are causing a bowel obstruction ( you can diagnose the obstruction but not the cancer), or if contrast is given in the GI tract first ( known as a upper or lower GI series). Ct scan is the radiologic test of choice, colonoscopy shows as wel ...Read more

Would advanced colon cancer show up on a CT scan of my abdomen ? Reg CT scan not virtual colonoscopy.

Imaging/biopsy: The imaging modality of ct scan could show findings that would be concerning for cancer, mass around your colon, enlarged lymph nodes in the same area. However, the diagnosis is made at biopsy, a piece of the mass under the microscope of a pathologist. Often the ct scan leads to the biopsy. Good luck, it is important to get the evaluation completed. ...Read more

Does a normal CT scan exclude pancreatic cancer?

Does a normal CT scan exclude pancreatic cancer?

Not entirely: Ct imaging is useful, but pancreatic cancer can be very difficult to visualize on ct. In fact, even in patients with known pancreatic cancer it's not unheard of for the tumor itself to be poorly or incompletely seen. If there's high suspicion, endoscopy and ultrasound are useful tests. ...Read more

Do abdominal/pelvic cat scans show ovarian cancer?

Do abdominal/pelvic cat scans show ovarian cancer?

Computed tomography : Can often detect abnormalities consistent with ovarian cancer, but a specific diagnosis with only imaging, except in rare circumstances, is ill advised. The analogy I use is that medical imaging is like showing a stranger a picture of your family reunion. They can distinguish young vs old, boy vs girl, etc, but won't be able to point to uncle bob or cousin sue. Diagnostic pathology is needed. ...Read more

Pet Scan (Definition)

Pet scans most often use a radioactive form of glucose, the energy source for most of the cells in our bodies. The pet scanner can detect and measure how much of the radioactive glucose analog, f-18 fdg, is in a particular organ or region. The areas using more glucose are hyper metabolic and generally more worrisome. Our brains and sometimes hearts prefer glucose as food, making ...Read more
