- A. multidetector row spiral CT.
- B. MRI.
- C. positron emission tomography (PET) with the administration of f-fluorodeoxyglucose.
- D. receptor scintigraphy with the use of a somatostatin analogue radiolabelled with radioactive gallium or technetium.
- E. scintigraphy with the use of iobenguane (MIBG) radiolabelled with radioactive iodine.
Hint
Most well-differentiated neuroendocrine tumours overexpress one receptor type that labelled analogues can target.
