Introduction: Various radiopharmaceuticals, including 67Ga, 201Tl, and 99mTc-sestamibi have been used to differentiate benign from malignant thyroid nodules. 99mTc-Tetrofosmin, a lipophilic cationic radiotracer, and 99mTc-sestamibi have also been reported to accumulate in thyroid tumors. In this study, we evaluated the role of 99mTc-Tetrofosmin in the differentiation of malignant from ben...
introduction: renal length measurement is an important diagnostic clue in several urinary tract abnormalities. although ultra sonography is the most frequent used modality for renal size estimation, renal diameter assessment by 99mtc-dmsa scintigraphy is of great value. by now, pointing to the renal size in the 99mtc-dmsa scintigraphy report has not been recommended by guidelines. if the validi...

Background: Local ablative treatments play an important role for patients who cannot be treated surgically. Radiofrequency ablation is a well-established alternative to surgical treatment of thyroid nodules, however it also has disadvantages. Microwave ablation (MWA) is a new minimally invasive treatment promising several improvements. The aim of this retrospective study was to evaluate the eff...
OBJECTIVE To determine the usefulness of 99mtechnetium (99mTc) immunoglobulin scintigraphy (99mTc IgG) in rheumatoid arthritis (RA) and in other arthritides. METHODS Scintigraphic scores were compared with the Ritchie index and biochemical variables of disease activity. RESULTS In RA, scintigraphic scores were reproducible and seemed to perform better than clinical scores. Moreover, the sco...
White blood cell (WBC) 99mTc-hexamethylpropyleneamineoxime (HMPAO) scintigraphy was performed in a patient with eosinophilic gastroenteritis. WBC accumulation was detected in the terminal ileum to descending colon, and pathological studies demonstrated eosinophilic infiltration at the same region. 99mTc-HMPAO-WBC scintigraphy was proved to be a useful tool for the detection of eosinophilic infi...
introduction: the purpose of the present study was to evaluate the effect of prednisolone on the sensitivity of bone scanning to detect the simulated closed fracture in the rat tibia. methods: a total number of forty eight adult, male nmri rats randomly assigned into two parts, one part for 4 and other for 8 weeks experiments. each part has been divided into four groups, one group not receivi...
osteitis fibrosa cystica is the classic patognomonic form of skeletal disease in hyperparathyroidism that characterizes with decreased cortical bone thickness compared to increased cancellous bone. we present a case of 52-year old female patient with osteolysis of the left calf on radiographic images. the bone scan detected multiple focal pathological accumulations in the skull, left tibia, bot...
Somatostatin receptors have been demonstrated on normal as well as activated human lymphocytes in the circulation and within the reticuloendothelial system such as Peyer's patches and the spleen [1]. Also, lymphocyte function such as proliferation and immunoglobulin synthesis has been showed to be affected by somatostatin [2]. Following the demonstration of the presence of high-density somatost...
