UNLABELLED In this study we compared whole body scintigraphy with Tc-99m-methoxyisobutylisonitrile (MIBI) and Iodine-131 NA (131I) for detection of residual and/or metastatic disease in well differentiated thyroid carcinoma. METHODS MIBI and I-131 scans were obtained in 60 patients. TSH measurements were done in all the patients prior to scintigraphy. RESULTS Out of 60 patients, for whom bo...

OBJECTIVE To assess the relevance of (99m)Tc-SestaMIBI (MIBI) scan in the diagnostic evaluation of thyroid nodules with oncocytic cytology. SUBJECTS AND METHODS Twenty-four patients with a single (or prevalent) 'cold' solid nodule with Hurthle cells (HC) at fine needle aspiration cytology (FNAC) were studied. Cytological diagnosis of oncocytic metaplasia (OM) or HC tumor (HCT) was made when H...

OBJECTIVES This study aims primarily to determine whether whole body MRI (WB-MRI) and Sestamibi Technetium-99m-bone marrow (MIBI) scans in the same patients produce the same estimate of disease load and location, and secondly, to study possible association between the bone disease detected by these scans and the effect on disease outcome and survival. Bone disease occurs in about 90% of multipl...

PURPOSE To compare the diagnostic value of 99Tcm-MIBI- SPECT and 18F-FDG-PET/CT in differentiating benign from malignant solitary pulmonary nodules (SPNs). METHODS 170 SPNs were involved in this study (78 with 99Tcm-MIBI-SPECT and 92 with 18F-FDG-PET/CT). Definite diagnosis of SPNs was determined by biopsy. The diagnostic efficiency of 99Tcm-MIBI-SPECT and 18F-FDGPET/ CT in differentiating be...

Incubation of BMG-1 cells with thallium chloride (201Tl) in the range of diagnostic dose did not show a smooth uptake curve and appeared to have an unsuspected deviation in initial phase. In the present study this unexpected phenomenon was explored, using commonly used radionuclides (viz., 201Tl and 131I). Comparison was made with technetium-99m pertechnetate (99mTcO4(-)) and technetium-99m lab...

BACKGROUND The aim of this study was to evaluate the value of semiquantitative analysis (SQA) of 99mTc-MIBI imaging in predicting early-stage cervical lymph node metastasis (CLNM) in thyroid carcinoma (TC). MATERIAL AND METHODS TC patients (n =106) undergoing surgical resection and histopathological examination were enrolled. All patients received 99mTc-MIBI imaging prior to surgery. P-glycopro...

BACKGROUND We investigated a novel technique, intraoperative (99 m)Tc-Sestamibi (MIBI) imaging (neck and excised specimen (ES)), using a large field-of-view portable gamma camera (LFOVGC), for expediting confirmation of MIBI-avid parathyroid adenoma removal. METHODS Twenty patients with MIBI-avid parathyroid adenomas were preoperatively administered MIBI and intraoperatively imaged prior to i...

In a canine model of reperfused myocardial infarction, we tested the hypothesis that after reperfusion, technetium-99m-hexakis-2-methoxyisobutyl isonitrile (Tc-MIBI) tomographic imaging still reflects occlusion blood flow when the tracer is injected before reperfusion. Nine anesthetized dogs underwent 2 hours of coronary occlusion followed by 3 hours of reperfusion ending by being killed. Refer...

OBJECTIVE The aim of this study is to investigate the use of (99m)Tc-methoxyisobutylisonitrile (MIBI) imaging for evaluating the treatment response of differentiated thyroid cancer (DTC) after the first administration of a high dose of (131)I. METHODS Patients with DTC who received (131)I therapy underwent (99m)Tc-MIBI imaging after successive increases in the therapeutic dose of (131)I, and ...
