FLT PET Imaging for Cervical Cancer

Summary

Our primary hypothesis is that \[18F\]FLT PET can identify active bone marrow in addition to metabolically active tumor. This trial will use FLT-PET imaging to define areas of active bone marrow in the pelvis. The radiation plan is then designed to spare that area, in hopes of keeping the bone marrow active during therapy. Bone marrow and tumor activity will be monitored using a sequence of FLT PET scans during the course of chemotherapy and radiation therapy.
