Lymphoma

Melanoma
- Preoperative staging for patients with clinically suspected lymph node involvement, or symptoms suspicious for distant metastases
- Preoperative staging for patients who have a high risk of systemic metastasis based on extensive locoregional tumor
- Preoperative staging in patients with known metastasis who may benefit from resection
- Postsurgical and restaging follow-up of patients at high risk for spread
Note: The sensitivity of PET/CT for detecting regional lymph node involvement is low due to micrometastatic disease which is too small to detect. Evaluation of local and regional lymph node metastases is performed by sentinel node mapping and biopsy.
