Abstract
- Bone scintigraphy is a very sensitive and cost-effective diagnostic method for detecting bony metastases of malignant neoplasm. However it has been reported that bone scan is less sensitive for early bony metastases, especially vertebral metastases. PET is a non-invasive clinical imaging methodology that can be used to assess such biochemical disturbance in tissue in vivo quantitatively with high resolution.We experienced two cases of small cell lung cancer with multiple bony metastases which were detected on PET imaging but not on planar bone scan. This case report suggests that FDG-PET will be a very effective diagnostic tool for bony metastases especially in clinically suspected case despite a normal planar bone scan.
