• Differentiate recurrent tumor from
radiation necrosis
• Differentiate primary CNS lymphoma from toxoplasmosis
• Exclude metastatic disease of the brain |
|
• Identify involved axillary nodes
or distant metastatic disease
• Exclude local recurrence of disease
• Evaluate response to treatment |
|
• Detect pre-treatment metastases
in newly diagnosed cancer |
|
• Detect locally recurrent or distant
metastatic disease in
patients with elevated or rising CEA who may be candidates
for surgical re-excision
• Rule out distant metastases for preoperative evaluation |
|
• Evaluate local extent of disease,
and exclude distant
metastases
• Evaluate disease to determine surgical appropriateness |
|
• Determine extent of local, regional,
and distant disease
• Detect recurrent/residual tumor following definitive
therapy |
|
• Distinguish malignant from benign
pulmonary nodules
• Stage for mediastinal or distant metastatic disease
• Use as part of radiotherapy treatment planning
• Detect recurrent/residual tumor following definitive
therapy |
|
• Determine extent of disease
• Measure treatment response |
|
• Identify extent of local and regional
disease spread in patients
with high risk melanoma (e.g., primary tumor ≥4mm),
or in
suspected recurrence |
|
• Evaluate local extent of disease
and exclude distant
metastases
• Measure treatment response and exclude recurrent/residual
tumor following definitive therapy |
|
• Detect recurrent/residual tumor
prior to surgical exploration or
additional chemotherapy |
|
• Differentiation of benign processes
such as pancreatitis,
mucinous cyst adenoma and pseudocyst from malignant
disease
• Rule out distant metastases for preoperative evaluation |
|
• Detect metastatic or locally recurrent
disease in patients with
elevated thyroglobulin after definitive initial treatment
and
negative I-131 examination |
