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...

We report the case of a 64-year-old woman who had a severe hypercalcemia. Serum calcium, intact parathyroid hormone (PTH), 1alpha, 25 (OH)(2 )vitamin D(3) levels were all elevated, and serum phosphorus level was decreased, which were all consistent with primary hyperparathyroidism (PHPT). (201)Tl/(99m)Tc subtraction scintigraphy failed to detect any abnormal accumulation in the neck and chest, ...

OBJECTIVE To compare single-photon-emission computed tomography (SPECT) imaging scans using 201Tl and 99mTc-MIBI in detection of viable myocardium, in regions compromised by infarction. METHODS Thirty-two (59.3 +/- 9.8 years old and 87% male) myocardial infarction patients were studied. All had Q waves on the ECG and left ventricle ejection fraction of < 50%. They underwent coronary and left ...

PURPOSE Imaging with (99m)Tc-sestamibi ((99m)Tc-MIBI) has been used to assess 170-kDa P-glycoprotein (P-gp) expression and predict chemotherapy responses in several types of malignancy, such as breast and lung cancers. The purpose of this study was to evaluate the relationship between (99m)Tc-MIBI accumulation in tumors and sensitivity to chemotherapy in gastric cancer patients. EXPERIMENTAL ...

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...

BACKGROUND Metastatic pulmonary calcification (MPC) is rarely reported in primary hyperparathyroidism, especially MPC develops quickly. We report such a case here with a literature review. CASE PRESENTATION A 41-year-old woman presented with cough and dyspnea. Data from clinical, radiological, pathological, technetium (99mTc)-methylene diphosphonate (MDP) bone scintillation imaging, and 99mTc...

background: people who have been administrated radiopharmaceuticals could be a source of radiation to their relatives, medical nurses, and people who are in contact with them. the aim of this work was to estimate radiation dose received by nuclear medicine nurses. materials and methods: in this study, the dose rates at various distances of 5 – 100 cm from 70 patients, who were administered diag...

A 34 year old woman with malaise, polyuria and nocturia as well as nausea and vomiting referred to perform a thyroid scan due to right thyroid lobe mass. The scan showed a cold nodule in the right thyroid lobe. Serum calcium of 16.9, serum phosphorus of 1.8 and PTH of 1156 were noticed in laboratory tests. Parathyroid scan with 99mTc-MIBI showed no abnormal tracer activity in the nec...
