The sentinel lymph node was defined as the first lymph node to receive drainage from a primary cancer. The aims of this study were to investigate the efficacy of radiocolloid lymphoscintigraphy and of the hand-held gamma probe procedure for sentinel lymph node biopsy in papillary thyroid carcinoma and to evaluate these results in clinical staging. A total of 99 consecutive papillary thyroid car...

BACKGROUND 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) has become an established method for detecting hypermetabolic sites of known and occult disease and is widely used in oncology surgical planning. Intraoperatively, it is often difficult to localize tumors and verify complete resection of tumors that have been previously detected on diagnostic P...

To improve the radiation resistance of Yb-doped fiber lasers, we investigate influence pre-radiation and photo-bleaching on gamma-radiated laser’s performance. When gamma dose is within 10 krad(Si) with a rate less than 0.4 rad(Si)/s, compared to output power non-pre-radiated laser, technique could enhance against gamma-ray. However, mode instability threshold was decreased, which caused by cum...

Methods: Reviewing steps 4 cases osteoid osteoma surgical removal. Results: Four patients diagnosed with and moved to During operation, excision tumour was assessed probe, avoiding leaving residual in field...
