Summary

This is a collection of F-18 NaF PET/CT images in patients with prostate cancer, with suspected or known bone involvement. Imaging was performed on a Phillips Gemini TF PET/CT scanner. based on 4x4x22mm LYSO crystal detection elements covering 18cm axial FOV and 57cm imaging transaxial FOV. The TOF timing resolution is 585ps. The scanner achieves a spatial resolution of 4.8mm at the center of the FOV. Data were reconstructed using the RAMLA iterative OSEM algorithm using 3 iterations and 33 subsets. The scanner uses CT based attenuation correction, along with randoms, normalization, dead time and a model based scatter correction. The CT component of the scanner is a 16 slice helical CT. The CT images were generated using a low Xray dose of 120KV, 60mAs setting.

The prescribed injected dose was 3mCi IV. Some of the patients had 2 baseline studies within 14 days of each other (with no intervening interventions). Many have follow-up PET/CT imaging performed following therapy (varied) at 6 +/-2months and 12 +/- 2 months. For scientific inquiries relating to this data set please contact Drs. Karen Kurdziel or Liza Lindenberg at karen.kurdziel@nih.gov or liza.lindenberg@mail.nih.gov.
