1. Utilize PET in confirming underlying osteomyelitis (Uosteo) complicating cranioplasty/craniofacial reconstructive surgery (cranSURG). 2. Illustrate the role of correlative imaging (CT, bone scans and MRI), in evaluating Uosteo. 3. Illustrate the utility of 3D surface rendering of merged PET and CT. 4. Demonstrate techniques of coregistering PET to CT/MR datasets, creating fused PET-CT/MR 3D rendered composite images.

Uosteo may complicate myocutaneous flaps. It is essential to determine Uosteo since management differs in complicated vs. uncomplicated grafts.  Bone scan, labeled WBC/Ga-67 and MRI are limited in surgically traumatized bone.  We explored the use of PET-CT in Uosteo complicating post cranial surgery. 9 PET in 7 pts for suspected Uosteo post cranSURG, were evaluated.  CT/MRI /bone SPECT were coregistered with PET into a common 3D space, the merged data were surface rendered and fused.  4/7 pts were neg for Uosteo by PET and clinical f/u, 2/7 pts were pos for Uosteo, 1 pt. had an infected titanium mesh.  Of 2 pts pos for Uosteo, f/u PET showed complete resolution in 1 pt, while the other had partial resolution.  In an atlas format the multimodality image findings will be demonstrated, emphasizing the utility of 3D images as a tool for tracking the sinuous sinus tracts presurgically.
