Posterior access to the lumbar disc spaces for posterolateral fusion scan has been technically challenging, frequently requiring the use of an approach surgery for adequate exposure.

In case of anatomical difficulties on PET assessment, a PET/CT fusion scan was performed.
A subsequent FDG-positron emission and computered tomography fusion scan (FDG-PET-CT) showed a 4 cm hypermetabolic solitary metastasis in the right lobe of liver with a FDG standard uptake value (SUV) of 7.6.
All of these lesions were highly avid for Fludeoxyglucose in the consecutive positron emission tomography CT fusion scan (FDG-PET-CT, Figure 1) and no other pathological findings were seen.
For more accurate computer-guided implant surgery, various studies, including the development of standardized methods to reduce errors in the fusion of scanned CT, model scan data, and doubled CT data and improvements in accurate surgical template preparation methods for minimum errors, are necessary.
SUVmax of lesions showing increased signal intensity and SUVR measured on fusion MRI/PET scans are more sensitive parameters for predicting clinical outcome than signal intensity on the MRI scan.
Optimizing PET and CT fusion, CT scans in exspiration were used.
After the anatomical-functional image fusion, the scans were analysed with respect to 3D-localisation and number of sentinel nodes.
