Perfusion scintigraphy using 99mTc-DTPA is valuable for evaluating pancreas transplants, especially when done serially. Serial studies help assess transplant function, detect issues like rejection or pancreatitis, and monitor changes over time.

Area of Science:

  • Nuclear Medicine
  • Transplant Surgery
  • Radiology

Background:

  • Pancreas transplantation is a complex procedure requiring careful post-operative monitoring.
  • Assessing pancreas transplant viability and function is crucial for patient outcomes.
  • Scintigraphic perfusion studies offer a non-invasive method for evaluating organ perfusion.

Purpose of the Study:

  • To evaluate the diagnostic utility of scintigraphic perfusion studies in pancreas transplant recipients.
  • To correlate scintigraphic findings with clinical diagnoses and transplant outcomes.
  • To determine the role of serial perfusion studies in managing pancreas transplants.

Main Methods:

  • Review of 56 scintigraphic perfusion studies (99mTc-DTPA) in 22 pancreas transplant patients.

  • Analysis of images for pancreatic perfusion, intensity relative to iliac artery, size, homogeneity, and definition.
  • Correlation of scintigraphic findings with clinical data, including function, rejection, pancreatitis, and arterial thrombosis.

    • Main Results:

    • Three studies showed no pancreatic perfusion; one correlated with arterial thrombosis, one with severe rejection, and one with normal function.
    • Decreasing perfusion on serial studies was linked to rejection (3 patients) and pancreatitis (1 patient).
    • Progressive loss of pancreatic definition on serial studies was observed in rejection (4 patients) and pancreatitis (1 patient).

    Conclusions:

    • Perfusion scintigraphy is a useful, albeit nonspecific, tool for evaluating pancreas transplants.
    • Serial perfusion studies provide valuable insights into transplant status and potential complications.
    • Scintigraphy aids in monitoring pancreas transplant function and detecting early signs of dysfunction.
