Applying PET/MR in Rectal Cancer.

November 4, 2019 updated by: Tel-Aviv Sourasky Medical Center

The use of the novel recently introduced PET/MR scanner is believed to be promising in RC management, providing great anatomical details and detailed metabolic characterization. Preliminary data indicate it may become a strong imaging modality for staging of RC and has the potential to be used as a predictive tool guiding individualized therapy in patients receiving nT, but confirmation on prospective studies is mandatory. The use of radiomics as analysis approach may assist in achieving a better understanding of the obtained image data, and thus a more accurate disease assessment.

Objectives

  1. To preliminary assess the potential diagnostic value of single PET/MR scan in RC staging and compare it to that of MRI alone, PET/CT alone, and combined MRI and PET/CT.
  2. To preliminary assess the potential value of PET/MR in predicting pMR to nT.
  3. To use radiomics analysis of PET/MR data to develop a quantification clinical tools that allow a more accurate and comprehensive assessment of RC patients.

Design Details

  • Primary Purpose: Diagnostic
  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Rectal Cancer Patients
Diagnostic test: PET/MR scan
whole-body PET/CT scan and pelvic PET/MR scan (MR protocol will include three plane fast spin echo T2 weighted, DWI and dynamic contrast enhanced imaging). The ad interim assessment will use a pelvic PET/MR scan only (without PET/CT), to avoid the radiation associated with whole body CT. In the staging and post-nT assessment, the addition of PET/MR to the standard use of PET/CT adds no radiation exposure.
