OBJECTIVES The aim of this study is to evaluate the usefulness of gastroesophageal reflux (GER) scintigraphy using the knee-chest (KC) position for the diagnosis of gastroesophageal reflux disease (GERD). METHODS The study subjects were 37 patients with GERD and 8 healthy volunteers (control group). Endoscopically observed esophageal mucosal breaks were evaluated with the Los Angeles classifi...

Diffuse pulmonary deposition of [99mTc]methylene diphosphonate (MDP) as well as abnormalities characteristic of hypertrophic pulmonary osteoarthropathy have been observed in a patient with Pneumocystis carinii pneumonia (PCP). The findings of the bone scan together with those in the corresponding scintigraphy, and roentgenograms of the chest and skeletal structures are presented. Parallel rever...

We investigated the usefulness of 99mTc-GSA scintigraphy for estimation of residual hepatic functions and postoperative changes of HH15 and LHL15. 99mTc-GSA scintigraphy was performed on 61 patients and following points were studied: 1) correlation between HH15-LHL15 and conventional liver function tests, 2) correlation between HH15-LHL15 and the Child classification, 3) relations of preoperati...

BACKGROUND Differentiated thyroid cancers (DTC) often form metastases in neck lymph nodes, lungs and bones. Other metastases--to the brain, kidneys, skin and liver are rare. Liver metastases of DTC occur in the terminal phase of the disease and predominantly do not accumulate radioiodine. Functional (accumulating radioiodine) metastases are very rare. MATERIAL AND METHODS In an 85 year old pa...

The patient with a history of bone pain and muscle weakness, was thought to have oncogenic osteomalacia as a result of biochemical investigations and directed to Nuclear Medicine Department for a whole-body bone scintigraphy and 111In-octreotide scintigraphy. There was no focal pathologic tracer uptake, but generalized marked increase in skeletal uptake on bone scintigraphy. Octreotide scintigr...

Introduction: In this study the automatic separation of oral and salivary gland activity and spontaneous secretion by means of factor analysis for quantitative salivary gland scintigraphy is introduced. Methods: After intravenous administration of 99mTc sodium pertechnetate, dynamic scintigraphy was performed. 20 minutes after tracer application 2 ml of lemon juice was delivered to stimulate t...

in-vitro labeling of rbc with 99mtc is an intricate procedure and there is always a need foran alternate blood pool imaging agent. the aim of this study was to prepare an effective nanosized liposome (nls) similar to human rbc for blood pool scintigraphy. this study formulatespeg-nls and non-peg-nls using film method plus high pressure homogenization technique.biodistribution studies were perfo...

the aim of this study was to assess the value of 99mtc-hexakis-2-methoxyisobutylisonitrile (mibi) scintigraphy in patients with clinical and radiologic features of primary or metastatic musculoskeletal tumors. methods: the scintigraphic findings for 84 patients were compared with the surgical and histologic findings. each patient underwent three-phase bone scan with 99mtc-methylene diphosphonat...

A primary carcinoid tumor of the thymus showing ectopic ACTH syndrome was evaluated scintigraphically with four radiopharmaceuticals and a fluorescence method. Iodine-123-MIBG and 201Tl-Cl scintigraphy clearly demonstrated the tumor. Gallium-67-citrate and 99mTc(V)-DMSA showed no tumor uptake. The fluorescence method confirmed numerous storage granules of norepinephrine. Iodine-123-MIBG scintig...

Purpose: Demonstrate the possible manifestations of SAPHO syndrome. Material and methods: 38-year-old woman with suspected syndrome were performed scintigraphy SPECT/CT for evaluate localization abundance process. Results: Osteosclerosis hyperostosis left clavicle, osteosclerosis L1 vertebra other, less pronounced changes, accompanied by active accumulation 99mTc-MDP, revealed. Conclusion: It i...
