Aim: This study aimed at evaluating the performance of an intraoperative gamma camera, named CarolIReS, to detect axillary drainage and to assess the removal of sentinel lymph nodes (SLN) in breast surgery.
Patients And Methods: SLN biopsy was performed on 25 patients and the CarolIReS camera was used preoperatively to localize SLNs. During surgery, individual removal of SLNs was performed using a gamma probe and their activity was measured with a gamma ray counter. At the end of surgery, the CarolIReS camera was used again to check the quality of surgery which was followed by surgical excision for remaining SLNs.
Results: The detection efficiency of the CarolIReS camera was 2.2 cps/kBq for 99"Tc activity in SLNs. In one case, it allowed the detection of a residual SLN with a low activity (0.5 kBq) which was massively metastatic.
Conclusion: Intraoperative cameras could be used to improve the efficiency of the SLN procedure.

Unlabelled: The aim of this study was to evaluate the ability of a prototype intraoperative mini gamma-camera, the CarolIReS, with a 50 x 50 mm field of view, to precisely localize sentinel lymph nodes (SLNs) and to determine their depth in a series of patients with infiltrative breast cancer requiring SLN excision.
Methods: With the use of phantoms, the broadness of the signal of an acquired projection was shown to linearly depend on its distance from the collimator. A preclinical ex vivo study of 25 excised SLNs demonstrated that SLN size did not influence depth estimation.

Aim: The aim of this study is to evaluate the performances of a new prototype handheld gamma probe in a series of patients with infiltrative breast cancer justifying sentinel lymph node (SLN) excision.
Methods And Patients: SLN excision was performed on nine patients being treated for infiltrative breast cancer. After preoperative radio-isotope injection and lymphoscintigraphy, individual removal of all radioactive nodes was performed after their localisation using a novel new prototype handheld gamma intraoperative probe named CarolIReS.
