Nuclear medicine imaging modalities assist commonly in surgical guidance given their functional nature. However, when used in the operating room they present limitations. Pre-operative tomographic 3D imaging can only serve as a vague guidance intra-operatively, due to movement, deformation and changes in anatomy since the time of imaging, while standard intra-operative nuclear measurements are ...

BACKGROUND The initial draining lymph node for a primary tumor is referred to as the "sentinel" node. Firstly adopted in the management of patients with cutaneous melanoma and breast cancer, it is now widely tested in cervical cancer. In patients with cervical cancer, lymph node status is the most important prognostic factor for survival. In patients with cervical cancer FIGO stage I and II pel...

AIM To define the sentinel node identification rate in breast cancer, the chronological evolution of this parameter and the influence of the introduction of a portable gamma camera. MATERIAL AND METHODS A retrospective study was conducted using a prospective database of 754 patients who had undergone a sentinel lymph node biopsy between January 2003 and December 2011. The technique was mixed ...

Liver metastases are an advanced stage of several types of cancer, usually treated with surgery. Intra-operative localization of these lesions is currently facilitated by intra-operative ultrasound (IOUS) and palpation, yielding a high rate of false positives due to benign abnormal regions. In this paper we present the integration of functional nuclear information from a gamma probe with IOUS, ...

The Intraoperative MRI is of great importance in the surgical removal of gliomas or cranial base tumors. However, the sole use of a intraoperative MRI is problematic, so that a dual system has been developed to optimize the utilization of the equipment, which can be used both for neurosurgical patients and for outpatient or stationary Patients. Within the framework of the new head Center at the...

introduction: sentinel node mapping has been used for laryngeal carcinoma in several studies, with excellent results thus far.in the current study, we report our preliminary results on sentinel node mapping in laryngeal carcinoma using intra-operative peri-tumoral injection of a radiotracer.   materials and methods: patients with biopsy-proven squamous cell carcinoma of the larynx were included...
