introduction: differentiation between infection and sterile inflammation is one of the most difficult medical problems and is relevant in many clinical situations. scintigraphy with radiolabeled antibiotics, еspecially labeled fluoroquinolones, is a promising tool for diagnosing bacterial inflammation. we have attempted to synthesize 99mtc-norfloxacin and studied its properties in experiment. m...

Sentinel node biopsy (SNB) in breast cancer is a promising surgical technique that avoids unnecessary axillary lymph node dissection. To optimize lymphatic mapping with radiopharmaceuticals, mammary lymphoscintigraphy with 30-50 MBq of technetium-99m-diethylenetriamine pentaacetic acid human serum albumin (99mTc-HSAD), technetium-99m-human serum albumin (99mTc-HSA), or technetium-99m-tin colloi...

Extramedullary pulmonary hematopoiesis is a rare entity with a limited number of case reports in the available literature only. We report the case of a 66-year-old man with known primary myelofibrosis, in whom a Technetium-99m sulfur colloid bone marrow scan with single-photon emission computed tomography (SPECT)/CT revealed a pulmonary hematopoiesis as the cause of pulmonary hypertension and s...

After intraventricular injection of 99mTc antimony sulfide in rabbits (n = 12) and cats (n = 14), radiolabeled colloid was imaged passing into the nasal mucosa and subsequently into the cervical lymph nodes. The cervical lymph nodes accounted for about 12% of the injected dose in rabbits sacrificed at 22-24 hr after injection and about 5% of the injected dose in cats sacrificed at 5-6 hr after ...

Quantitative lacrimal scintillography, using 99mTc sulphur colloid, a high resolution gamma camera, and quantification using a digital computer, is a highly effective way of assessing lacrimal physiology, and of establishing normal flow and drainage values against which pathological cases may be compared.

OBJECTIVE To evaluate the performance and feasibility of sentinel lymph node biopsy in breast cancer patients using technetium-99m (99mTc) sulphur colloid and gamma probe. METHODS From May 2000 to March 2001, 70 patients with a tumour less than 5 cm with clinically negative axillary lymph nodes underwent sentinel node biopsy followed by standard axillary dissection. 99mTc sulphur colloid was ...

OBJECTIVE To report a case of splenosis and to review its diagnosis and treatment in the related literature. METHOD We report the case of an asymptomatic 49-year-old man with splenectomy performed when he was 22. Lumbo-sacral MRI showed a left perirenal mass probably with renal origin. RESULTS CT scan ruled out the renal origin. Due to previous splenectomy, splenosis was suspected. 99mTc-la...

IMPORTANCE Sentinel lymph node biopsy has been proposed as an alternative to up-front elective neck dissection (END) for determination of pathologic nodal status in patients undergoing surgical treatment for oral cavity squamous cell carcinoma (OSCC) with clinically negative neck (cN0). Sentinel lymph node biopsy using current standard tracer agents and imaging adjuncts such as radiolabeled sul...
