Overview
Positron emission tomography (PET) and scintigraphy are among other imaging modalities that may be helpful in the diagnosis and management of appendix cancer.
Other Imaging Findings
- The followings are among other imaging modalities that may be helpful in the diagnosis and management of appendix cancer:
- Somatostatin scintigraphy with 111-indium-octreotide
- High sensitivity and specificity for both functioning and non-functioning carcinoid tumors
- Useful in treatment planning
- Indicates response to octreotide analogues [1]
- Bone scintigraphy with 99mTc-methylene diphosphonate (99mTcMDP)
- MIBG scintigraphy [2]
- distinguish between primary and metastatic tumors.
- Detecting carcinoid tumors that are negative on OctreoScan
- Positron emission tomography (PET) : Figure below demonstrates Post-operative PET-CT scan of a patient with carcinoid tumor.[3]
