- Allocation: RANDOMIZED
- Intervention Model: CROSSOVER
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: QUADRUPLE
- Phase: None
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* Patients presenting for SLN imaging for melanoma or who have had an excisional biopsy for melanoma of the thorax and appendicular structures;~* Patients scheduled to receive two or more injections of Tc-99m SC for the purpose of clinical management of melanoma or who have had an excisional biopsy for melanoma of the thorax and appendicular structures.~Exclusion Criteria:~* Patients presenting for SLN imaging of lesions involving the breast, ear, nose, and genitourinary regions;~* Patients scheduled to receive only a single injection of Tc-99m SC;~* Pregnant or breast feeding women.

- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: 122 Years
- Healthy Volunteers: f

Study Arms:
- pH altered first (Type: ACTIVE_COMPARATOR): The first injection administered will be the pH altered solution. The second injection will be the standard of care solution (opposite order). The remaining injections will be randomly assigned as either standard of care or pH altered.
- Standard of Care first (Type: ACTIVE_COMPARATOR): The first injection administered will be the standard of care solution (SOC). The second injection will be the pH altered solution. The remaining injections will be randomly assigned as either standard of care or pH altered.

Based on this trial design, predict the completion outcome and termination type (if applicable).
