Evaluation of surgical gamma probes for sentinel node localization in cervical and vulvar cancer
Nucl. Med. Rev 2005;8(2):105-110.
Abstract
BACKGROUND: Sentinel node (SN) scintigraphy for cervical
and vulvar cancer guides the gynaecological oncologist in finding
the metastatic lymph nodes during lymphadenectomy. The
role of the surgical gamma probe in the sentinel node concept
in gynaecological oncology is to localise (SN) both intra-operatively
and transcutaneously. Intra-operative hand-held collimated
gamma probes are increasingly used for detection of the sentinel
lymph node.
MATERIAL AND METHODS: A comparative evaluation of handheld gamma probes: Neoprobe 1500, Europrobe, Gamma Finder®, Gamma Ray Prospector GRP1 and GPR2 was performed using different detection methods. Laboratory tests were performed in which sensitivity, spatial resolution and angular sensitivity were evaluated.
RESULTS: The results for each gamma probe were summarised and discussed.
CONCLUSION: Awareness of a gamma probeís capabilities and limitations should be considered in the appropriate selection of a device.
