3D NLS method. Scanning was performed using metatron hunter 4025 scanner with software program which allows visualization of all skeletal bones, surrounding soft tissues and lymphatic nodes. NLS-research started from the assessment of the whole body and then the following body parts were assessed at detailing: head and neck; torso and proximal shoulder parts; pelvis and proximal femora parts. Research protocol for each anatomical part included the following data: large-scale NLS-scanning in 3D mode at 3 mutually transverse planes; ultramicroscanning mode in the regions of interest with spectral-entropy analysis. Total time required for the research was approximately 30 minutes.

NLS-graphy performed by the sequential scanning of three anatomical parts allows more effective (in comparison to bone scanning) detection of bone metastases in the majority of anatomical parts. NLS-graphy is a promising screening technique of bone metastases and it allows simultaneous detection of metastases in other organs; it helps the clarification of further examination program and the reduction of applied number of diagnostic techniques.
