declipseSPECT vs. Blue Dye
|
Blue dye is often used in combination with Tc99m marking of SLN. Its limitation (similar to ICG marking) is that there must be a direct visual contact to the SLN in order to identify the node. Literature shows that a double marking of blue dye and Tc99m using radio-guided surgery has the highest success rate in the removal of the SLN. Blue dye needs direct access through invasive procedures and does not facilitate any targeting and orientation before the incision started, resulting in a digging for the SLN.
Blue dye is also limited to anatomical marking of the SLN and thus cannot be applied to primary tumor marking and resecting.

declipseSPECT vs. Only Gamma Probes
| declipseSPECT is an extension of gamma probes to 3-D imaging and navigation. The same functionality and workflow as using gamma probes are available in declipseSPECT. When using a gamma probe the surgeon has to create a picture of the activity distribution in her/his mind and apply this to the access and removal of the labeled tissue. When using declipseSPECT the 3-D image of radioactive concentration and distribution is created by the system and visualized for guidance. declipseSPECT thus extends the functionality of a gamma probe for safer and more reliable procedures, guiding the removal in complex cases where fine navigation through critical anatomy is required. |

declipseSPECT vs. Only Intra-operative Gamma Cameras
| Planar 2-D projective images of radioactivity usually have a good lateral resolution, however lack occlusion, have no depth information and no anatomical correlation. The 3-D solution features images in all dimensions and provides a direct correlation with the anatomy not only for image viewing as in the 2-D case, but also for localization and targeting of structures during surgery. |
