Trial Title: Positron Emission Tomography - Computed Tomography (PET-CT) Scanning in Chronic Graft Versus Host Disease (cGvHD)

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

Eligibility Criteria:
Inclusion Criteria:~* Prior allogeneic hematopoietic stem cell transplant (+/- DLI)~* As per current recommendations, no interval from allo HSCT will be required to differentiate acute from chronic Graft versus Host Disease (GvHD)~* Patients must have had negative routine restaging PET-CT scans~* Patients may not have had any more than two weeks' specific treatment for chronic GvHD. (It is recognized that some patients develop chronic GvHD while on immunosuppressive prophylaxis; such patients will remain eligible, even if dose adjustment of these prophylactic agents occurs. The two week interval pertains to the use of additional agents in this case.)~* Diagnosis of chronic GvHD must be confirmed. In the usual case, tissue biopsy will be required; however, some chronic GvHD patients do not require tissue biopsy for confirmation. The PI and co-investigator must agree on eligibility.~* Per patient approval by PI and one additional co-investigator~* Informed consent~Exclusion Criteria:~* Patients with a malignancy not in remission will be excluded.~* Negative routine pregnancy testing. Patients either pregnant or unwilling to use satisfactory contraception (if appropriate) will not be eligible. All female patients must use a highly effective birth control method or a combination of 2 additionally effective birth control methods while in this study. Examples of highly effective birth control are: a condom or a diaphragm with spermicidal jelly, oral, injectable, or implanted birth control, or abstinence.

- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: None
- Healthy Volunteers: f

Study Arms:
- PET-CT (Type: EXPERIMENTAL): Patients who have a negative routine PET-CT evaluation followed by onset and confirmation in accordance with NIH guidelines, will receive another PET-CT scan prior to initiation of therapy for chronic GvHD.

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