What protocol would be selected to rule out islet cell tumor?

Selecting the protocol to evaluate for an islet cell tumor should focus on the pancreas, as this is where these tumors typically arise. Islet cell tumors, which can produce hormones such as insulin, glucagon, or others, are specific to pancreatic tissue. Therefore, imaging the pancreas is essential to identify any abnormal growths or lesions that may signify the presence of these tumors.

In evaluating the pancreas, various MRI sequences can provide detailed information about the structure, size, and characteristics of any tumors. This approach is vital to correctly diagnose or rule out pancreatic islet cell tumors.

The emphasis on pancreatic imaging makes it unequivocally the most appropriate choice in this scenario. The other options, such as examining pelvic floor laxity, liver iron levels, or adrenal glands, do not pertain to the detection or evaluation of islet cell tumors, as they involve entirely different anatomical areas and pathologies.
