Is there an additional value of SPECT/CT over planar lymphoscintigraphy for sentinel node mapping in oral/oropharyngeal squamous cell carcinoma?
SPECT/CT has the potential to detect more SLNs, which might harbor occult disease, than LS alone. With regard to the excellent results achieved with LS and the intraoperative use of the gamma probe, SPECT/CT is not indispensable for successful SNB. Both imaging modalities have difficulties in detecting level I sentinel nodes close to the injection site.
Incremental and single trauma produced equivalent subfailure cervical spine injury in simulated impacts, for the experimental conditions studied. This study may facilitate greater use of the incremental trauma protocol in future experimental designs.
