Purpose: The incident at the Fukushima Daiichi nuclear power station in 2011 has again raised concerns with the public regarding radiation exposure, especially so in medical workers and patients undergoing treatment involving the use of radiation. Radioisotopes are currently used during sentinel node navigation surgery (SNNS) in operating rooms without radiation monitoring. To re-evaluate the s...
A 7-month-old girl with history of persistent left chylous pleural effusion was referred for lymphoscintigraphy. A previous chest computed tomography (CT) scan demonstrated a small to moderate-sized left pleural effusion but could not identify the lymphatic leakage site. Lymphoscintigraphy using filtered (99m)Tc sulfur colloid showed minimal focal activity in the lower chest. A correlative sing...
Background. Most institutions require a patient undergoing sentinel lymph node biopsy to go through nuclear medicine prior to surgery to be injected with radioisotope. This study describes the long-term results using intraoperative injection of radioisotope. Methods. Since late 2002, all patients undergoing a sentinel lymph node biopsy at the Yale-New Haven Breast Center underwent intraoperativ...
Sentinel node biopsy can decrease the morbidity of breast cancer treatment significantly by sparing many patients of axillary lymph node dissection and resulting arm lymphedema. Despite widespread use of sentinel node mapping for breast cancer patients almost all aspects of this procedure are controversial; such as: type of the radiotracer, eligibility, time of injection, etc. One of these con...
Antimony sulfide (Sb2S3) has gained extensive attention in solar cells due to their potential as a low-cost and earth abundant absorber material. In solar cell absorber, the optoelectrical properties such as energy band gap and absorption coefficient of Sb2S3 play an important role, which have strong relationships with their crystal structure, lattice parameter and crystallite size. Hence in th...
Interferon (IFN) provides effective treatment in some patients with chronic hepatitis. The clarification of factors predictive of therapy response would be helpful in identifying patients who would benefit from treatment. In this study, we evaluated the potential utility of Tc-99m sulfur colloid liver/spleen and Tc-99m-disofenin hepatobiliary scintigraphy to predict therapy response to IFN in p...
AIMS To evaluate the accuracy of sentinel lymph node biopsy in breast cancer patients at this institution, using combined technetium-99m ((99m)Tc) sulphur colloid and patent blue vital dye. METHODS From March 2007 to July 2008, 50 patients with a tumour of less than 3 cm and with clinically negative axillary lymph nodes underwent sentinel lymph node biopsy (SLNB), followed by axillary lymph n...
STUDY OBJECTIVES The objective of this study was to evaluate the feasibility of the sentinel lymph node (SLN) biopsy in peripheral clinically stage I or II non-small cell lung cancer (NSCLC) using (99m)Tc colloid and a hand-held gamma detection probe, associated with a blue dye technique. DESIGN Prospective study. SETTING Royal Brompton Hospital, London, UK; and Hopital Nord, Saint Etienne,...
