A detailed answer to the question “What is the most sensitive investigation of pancreatic carcinoma?” requires a comprehensive look at the various diagnostic tools available. In general, imaging techniques such as CT, MRI, PET, and endoscopic ultrasound are the most sensitive investigations to diagnose pancreatic carcinoma.
CT and MRI Scans
CT and MRI scans are the most commonly used imaging techniques to diagnose pancreatic cancer. Both of these imaging techniques allow for detailed examination of the pancreas. CT scans are used to detect the presence of a tumor, its size, and its location. MRI scans are more sensitive than CT scans in detecting the presence of a tumor as well as its size and location.
PET Scans
Positron emission tomography (PET) scans are used to detect the metabolic activity of pancreatic tumors. This imaging technique can detect even very small tumors that may not be seen on CT or MRI scans.
Endoscopic Ultrasound
Endoscopic ultrasound (EUS) is a relatively new imaging technique for diagnosing pancreatic cancer. EUS uses sound waves to create an image of the pancreas and surrounding structures. This technique is more sensitive than CT or MRI scans, and can detect small tumors that may not be seen on these scans.
The most sensitive investigation of pancreatic cancer will depend on the individual patient and the type and stage of the cancer. Imaging techniques such as CT, MRI, PET, and endoscopic ultrasound are all useful in diagnosing this condition.
