Hybrid Modality Fusion of Planar Scintigrams and CT Topograms to Localize Sentinel Lymph Nodes in Breast Lymphoscintigraphy: Technical Description and Phantom Studies
Figure 6
Comparison of scintigram-CT topogram method to conventional lymphoscintigraphy. Anterior (a) and lateral (b) views of ten-minute emission images, conventional localization images, and planar scintigrams fused with CT topograms, of an anthropomorphic thorax phantom with a simulated internal mammary SLN. The current acquisition and processing workflow provides the physician with a visual comparison of the conventional and proposed method of localization. The anterior view of the scintigram-topogram fused image (a-right) provides location information for the internal mammary lymph node relative to the ribs and sternal notches.
