How accurate is a CT at detecting pancreatic cancer?

How accurate is a CT at detecting pancreatic cancer?

Imaging with CT: Can observe some cases, but will miss others, so it is not the best, endoscopy, endoscopic ultrasound, and ERCP or mr-cholangiography help, but all require biopsy proof. Next is categorizing for resection, the only successful treatment, and the vessels (sma, smv, portal vein) are the critical facts, as well as nodes, peritoneal and distant sotes of mets. ...Read more

Computed Tomography (Definition)

Computed tomography is also known as CT scan. 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

Why would it not be practical to use CT scans to detect pancreatic cancer?

Size, detectability: Ct scans will indeed show the mass of a pancreatic cancer once it reaches a certain size, but most cases are advanced by the time the primary tumor is large enough to see on a ct scan. So it isn't a question of "practicality", but one of what the ct is useful for. It can't be relied upon as a screening tool (plus it involves radiation exposure). ...Read more

Would CT pick up pancreatic cancer?

Would CT pick up pancreatic cancer?

Possibly: There are different types of imaging that may demonstrate a mass, or the effects of a mass or stricture in the ducts of the pancreas. Ct may show a mass, but often a biopsy, which is interpreted by a pathologist, is necessary to confirm a diagnosis of cancer. ...Read more

Can pancreatic cancer or cancer in pancreas be detected with CT scan?

Can pancreatic cancer or cancer in pancreas be detected with CT scan?

Often: Ct scan is a very good way to detect pancreatic cancer, but there are a few caveats. One, no test is 100% accurate. Two, some cancers may not be detected on ct scan because of the way the study was performed. Three, some may not be detectable due to small size or location. There may need to be other tests such as ERCP or endoscopic ultrasound. ...Read more

If pancreatic cancer was the cause of urq disc in 34yr would it be advanced enough not to be missed on CT scanw contrast?Test normal but still worried

If pancreatic cancer was the cause of urq disc in 34yr would it be advanced enough not to be missed on CT scanw contrast?Test normal but still worried

Probably not : Symptomatic pancreatic cancer is usually easy to detect by ct. A normal scan, especially in a 34 year old, makes pancreatic cancer very unlikely. There are, however many other mire common causes of abd pain such as gallbladder disease and ulcers that are not well detected by ct. If pain persists see you physician for additional testing. ...Read more

Endoscopic US: Has the highest sensitivity for detecting pancreatic masses. However, it's invasive and not readily available in some areas. There are specific ways to image the pancreas with ct that improve the test. ...Read more

If MRCP & CT scan with contrast were clear of Pancreatic Cancer, what are chances EUS can find Pancreatic Cancer? Are odds on my side with clear MRCP?

If MRCP & CT scan with contrast were clear of Pancreatic Cancer, what are chances EUS can find Pancreatic Cancer? Are odds on my side with clear MRCP?

Pancreatic cancer: Was the CT tailored for pancreatic mass protocol? If so it is highly accurate for detecting even very small panc masses. If it was a routine CT, the accuracy is still high, but very small tumors may not be seen. MRCP is also not specifically tailored to look for panc mass, so very small lesions may not be seen. No test is 100%, so it is always possible that another test could pick something up. ...Read more

If pancreatic cancer in body or tail is causing symptoms, would it show up on a iv contrast ct scan?

If pancreatic cancer in body or tail is causing symptoms, would it show up on a iv contrast ct scan?

Yes it would: CT scan of the abdomen is a reliable to test to check for Cancer of the Pancreas. So you do not have to think too much about this as a source of your symptoms. Go see a Gastroenterologist if symptoms persist for more than a week or two. ...Read more

Person diagnosed with pancreatic cancer. Had whipple operation and past benign pet/ct scans over past 6 months. Can person think this as cancer free?

Person diagnosed with pancreatic cancer. Had whipple operation and past benign pet/ct scans over past 6 months. Can person think this as cancer free?

Not entirely: Scans cannot detect small cells that are in the process of growing. It is however a positive sign that there was nothing seen in the scan. Best to foow the recommendation of the medical and surgical oncologists, and have the recommended follow up scans. Hope this helps! ...Read more

Will a ct scan without contrast show pancreatitis or pancreatic cancer? Or damage to the liver?

Will a ct scan without contrast show pancreatitis or pancreatic cancer?  Or damage to the liver?

Yes: In some cases a noncontrast ct scan can show pancreatic cancer,changes that could suggest pancreatic inflammation and liver diseases. However a negative scan does not rule out these diseases. ...Read more

Pancreatic Cancer (Definition)

Cancer of the pancreas are fast growing abnormal cells. These can be adenocarcinoma that can grow quickly, difficult to diagnose at an early stage & only sometimes can be removed with surgery. Endocrine cancers tend to be slower growing & may produce hormones & are surgically removed. Cystic cancers also may have better success with surgery. All of these can be difficult ...Read more

Pancreas (Definition)

Abdominal organ. It is digestive organ: it secretes enzymes into the small bowel which break down food and help its absorption. It is also an endocrine organ: it produces hormones involved in sugar control and control of digestion. Insulin is one of these hormones. Diabetics either lack Insulin (type 1 diabetes) or have inadequate ...Read more
