Magnetic resonance (MR) imaging helps detect pancreas transplant rejection. MR imaging findings correlate with acute, recovery, and chronic rejection stages, aiding early diagnosis.

Area of Science:

  • Radiology
  • Transplant Surgery

Background:

  • Pancreas transplantation is a life-saving procedure for select patients with type 1 diabetes.
  • Monitoring pancreas allograft function and detecting rejection are critical for long-term graft survival.

Purpose of the Study:

  • To evaluate the utility of magnetic resonance (MR) imaging in diagnosing pancreas allograft rejection.
  • To characterize MR imaging findings associated with different stages of pancreas allograft rejection.

Main Methods:

  • Eighty-eight MR imaging studies were performed on 31 pancreas transplants in 30 patients.
  • MR imaging sequences included T1-weighted and T2-weighted images.
  • Imaging findings were correlated with clinical data and outcomes.

Main Results:

  • Postoperative pancreas grafts typically appeared enlarged and inhomogeneous.
  • Acute rejection showed decreased T1 and increased T2 signal intensity.
  • Chronic rejection was characterized by small grafts with low signal intensity on both T1- and T2-weighted images.

Conclusions:

  • MR imaging is valuable for detecting early pancreas allograft rejection.
  • MR imaging findings can differentiate between acute, recovery, and chronic rejection phases.
  • Combined with clinical and laboratory data, MR imaging aids in managing pancreas transplant recipients.
