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, ...

Purpose: Tc-99m-MIBI accumulates in only viable cells. In patients with bone and soft tissue sarcomas, preoperative chemotherapy is essential and the early prediction of the tumor response to chemotherapy would be beneficial for the planning of treatment strategy. The purpose of this study was to assess whether the change of Tc-99m-MIBI image from pre-chemotherapy to the early to middle of the ...

OBJECTIVE 99mTc-tetrofosmin and 99mTc-sestamibi are approved tracers for myocardial perfusion studies. Recently, a 99mTc-MIBI preparation from a different manufacturer (99mTc-cardiospect-MIBI) has been introduced to the market. Therefore, the aim of this study was the evaluation of 99mTc-tetrofosmin as well as of two different 99mTc-labeled MIBI tracers with regard to differences in imaging qua...

PURPOSE The differentiation of oncocytoma from renal cell carcinoma (RCC) remains a challenge with currently available cross-sectional imaging techniques. As a result, a large number of patients harboring a benign oncocytoma undergo unnecessary surgical resection. In this study, we explored the utility of 99mTc-MIBI SPECT/CT for the differentiation of these tumors based on the hypothesis that t...

This study has aimed to determine the diagnostic value of the scintimammography with 99mTc-MIBI in the detection of primary breast cancer and to verify its clinical usefulness. Sixty-three female patients (age range 27-83) with breast lesions detected by physical examination, ultrasonography, and/or mammography were prospectively included in this study. An anterior and prone lateral planar 99mT...

In 30 patient with single cold thyroid nodule and normal thyroid function tests, 99mTc-MIBI scan is performed. The nodules are divided to hot (10), Warm (12) and cold (8). FNA reported papillary Ca in 4, suspicious follicular neoplasm in 3 and 23 benign lesions. 7 patients were operated on and had final pathology reports (4 papillary Ca and 3 benign lesions). All the nodules with no MIBI ...

objectives: multidrug resistance (mdr), which may be due to the over expression of p-glycoprotein (pgp) and/or mrp, is a major problem in neoadjuvant chemotherapy of osteosarcoma. the aim of this study was to investigate the role of tc-99m mibi scan for predicting the response to pre-operative chemotherapy. materials and methods: twenty-five patients (12 males and 13 females, aged between 8 and...

POLSKIE ARCHIWUM MEDYCYNY WEWNĘTRZNEJ 2016; 126 (3) MM is characterized by malignant proliferation of clonal plasma cells and excessive formation of monoclonal immunoglobulin.1 99mTc-MIBI is a radiotracer commonly used in myocardial perfusion imaging (FIGURE 1C). In literature, there have been reports on the use of 99mTc-MIBI in the diagnosis of MM since 1996.2 In a multicenter study conducted ...

Coronary stent restenosis rate following implantation is considerably high. The adenosine stress gated myocardial perfusion imaging (G-MPI) method has been widely used in the diagnosis, risk stratification and prognosis evaluation of coronary heart disease; however, the high cost of adenosine limits its clinical application. The aim of the present study was to investigate the efficacy of adenos...
