Please assess the completion status of the following clinical trial:

Trial Title: Quantifying Oxygen Utilization of Tumors Using Oxygen-Enhanced Molecular MRI

Study Design Characteristics:
- Allocation: None
- Intervention Model: SINGLE_GROUP
- Observational Model: None
- Primary Purpose: OTHER
- Time Perspective: None
- Masking: NONE
- Phase: None
- Number of Arms: 1.0

Eligibility Criteria:
Inclusion Criteria:~* Healthy volunteers will include persons who at the time of scans do not present with known neurological conditions that might impact tissue imaging results~* Patient participants should have suspected or pathology-confirmed diagnosis of a brain tumor (any histological subtype including brain metastases)~* All participants must be able to obtain an MRI scan and must be able to safely breathe high concentrations of oxygen~Exclusion Criteria:~* Participants with contraindications to MRI including metal implants~* Participants who are deemed not able to or not safe to breath high concentrations of oxygen

- Gender: ALL
- Minimum Age: None
- Maximum Age: None
- Healthy Volunteers: t

Study Arms:
- Feasibility (ASL,pH-Weighted amine CEST, O2-Weighted SAGE-EPI) (Type: EXPERIMENTAL): Participants undergo ASL perfusion, pH-weighted amine CEST, and oxygen-weighted SAGE-EPI , while breathing normal room air (21% oxygen). Patients then undergo another ASL perfusion, pH-weighted amine CEST, and oxygen-weighted SAGE-EPI while breathing medical grade air (100% oxygen). Total ASL perfusion, pH-weighted amine CEST, and oxygen-weighted SAGE-EPI imaging scan time is 60 minutes.

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