Introduction
Imaging supports donor selection pre transplant evaluation and postoperative surveillance for complications and rejection in organ transplantation. Modalities include ultrasound CT MRI and nuclear medicine depending on organ and clinical question. Timely imaging guides surgical planning and postoperative management.
Pre Transplant Assessment
CT angiography and MRI evaluate vascular anatomy and organ morphology for donor selection and surgical planning. Functional imaging such as nuclear renal scans or cardiac assessment informs candidacy. Multidisciplinary evaluation integrates imaging with clinical and laboratory data.
Postoperative Surveillance
Ultrasound monitors graft perfusion and detects vascular complications and fluid collections while CT and MRI evaluate complex complications and biliary or vascular issues. Biopsy guided by imaging confirms rejection or infection when indicated. Imaging follow up protocols vary by organ and center practice.
Long Term Monitoring
Imaging detects chronic complications such as fibrosis vascular stenosis and neoplasia in transplant recipients and supports long term care. Coordination with transplant teams ensures appropriate timing and modality selection. Research into non invasive imaging biomarkers aims to reduce biopsy frequency and improve early detection.
