Improved sentinel node identification by SPECT/CT in overweight patients with breast cancer.

Unlabelled: Overweight has been reported as a cause for the nonvisualization of sentinel nodes (SNs) on preoperative planar lymphoscintigraphy in patients with breast cancer. The purpose of this study was to assess whether SPECT/CT may improve SN identification in overweight patients.

Methods: Lymphoscintigraphy was performed in 220 consecutive patients with breast cancer.

Coincidence imaging using 2 dual-head gamma-camera systems, with and without attenuation correction.

Objective: Coincidence imaging enhances the potential for imaging a greater number of patients with 18F-FDG in centers that do not have dedicated PET systems. The purpose of this study was to compare, in a clinical setting, coincidence imaging for tumor detection using 2 dual-head gamma-camera systems, one equipped with a 5/8-in. (16 mm) detector (CoDe5) and the other equipped with a newly designed 1-in.
