Appendix cancer other imaging findings
Introduction
Overview
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
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[1]
- High sensitivity and specificity for both functioning and non-functioning carcinoid tumors
- Most sensitive imaging method to evaluate extrahepatic metastases
- Useful in treatment planning
- Indicates response to octreotide analogues
- Bone scintigraphy with 99mTc-methylene diphosphonate (99mTcMDP)[2]
- MIBG scintigraphy [2]
- Distinguish between primary and metastatic tumors
- Detecting carcinoid tumors that are negative on OctreoScan
- Positron emission tomography (PET):
- PET–CT scan will show high uptake in the metastasis points as well residual tumor and/or peritoneal carcinomatosis.
- Figure below demonstrates post-operative PET-CT scan of a patient with carcinoid tumor.[3]
