Ct Scan Pancreatic Protocol
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
PET/CT scan: You need to fast for 4 hours first, then you will recieve an injection of a small amount of radioactive glucose (i.e. Sugar). Next you will sit in a recliner chair for about 70 minutes to allow the glucose to distribute throughout you. Then you will lie on your back on the pet/ct scanner (a tunnel shaped machine) for 20 minutes. There are no side effects from the test or restrictions afterwards. ...Read moreSee 2 more doctor answers
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
Unreliable: Specialized cts that are designed to identify colon cancers (ct colonography) are available, but require a specific bowel prep and regimen to be effective. Routine ct scans will miss many small colon cancers that colonoscopy will find--colonoscopy remains the gold-standard. ...Read moreSee 2 more doctor answers
Different mechanisms: Mri uses magnetic radiation( no x-ray) for anatomic localization and characterization of different parts of body, water and fat constitution of different tissues.Ct uses x-ray to characterize anatomy of body, better for bone than mr.Pet, bone, gallium scans use radio tracers intravenously.Petglucose metabolism of tumors, gallium (infection/tumor), bone scan for fxs, tumors, infection bone metabolism. ...Read more
No: Iv contrast is often not used when the ct is for the purpose of looking for renal stones and in people with a history of contrast allergy or renal disease. It is often helpful in assessing persons with nonspecific abdominal symptoms as it will better show areas of inflammation, infection, and tumor. ...Read moreSee 1 more doctor answer
No contrast CT showed ill defined hypodense area on hepatic lobe. Ordered new CT w contrast w liver mass protocol not hemangioma protocol concerning?
Get iv contrast CT: There are many reasons to have a liver mass, more often than not, they are benign, but clearly depending on past medical history, It is difficult without contrast to differentiate these lesions, there are various ways to give intravenous contrast. A hemangioma protocol is also known as a triphasic study, allows one to look at three phases of liver perfusion but more complex to do. ...Read more
Quite different: Ct involves xray type radiation with cross sectional imaging in transaxial, sagittal, and coronal projections. Nuclear medicine, internal irradiation either injected intravenously, inhaled, ingested, injected subcutaneously.Ivp uses injection of contrast material for visualization of kidneys and bladder with x-ray. Mr imaging uses no ionizing radiation magnetic fields to generate x-sectional images. ...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 moreSee 3 more doctor answers
Whats better for diagnosing pancreatic cancer.... Ct scan or mri? I've had normal ultrasound and CT scan with contrast. Still worried.
What are the chances an ultrasound, Mri/mrcp, ercp, and ct scans or imaging miss advanced liver cancer?
If it is tailored: For liver mass, and technically adequate(i.e. no artifacts that might obscure anatomy), it would be nearly impossible to miss a large liver tumor. ...Read more
Since I had-: -pancreatitis, l have gone thu the screening process. Amylase is high sometimes, endoscopic ultrasound, MRI with IV contrast all have been done & all is clear. Had in Jan, 2016 & now have my final MRI with IV contrast on 1 NOV 2016. That's the workup after pancreatitis, as far as screening, I would feel amylase levels. The rest R costly 4 screening ...Read more
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
