OBJECTIVE We sought to determine the usefulness of the (99m)Tc-MIBI (MIBI) washout rate for the evaluation of steroid therapy in cardiac sarcoidosis (CS). METHODS Eleven CS patients underwent MIBI myocardial SPECT both before and 6 months after initiating steroid therapy. The washout rate (WOR) of MIBI was calculated using early and delayed polar map images. The washout score (WOS) of MIBI wa...

BACKGROUND (18)FDG-PET plays a significant role in diagnosing malignancy of lung lesions but remains an expensive test available at a limited number of sites in Italy. OBJECTIVE We prospectively compare the diagnostic accuracy of (99m)Tc-MIBI- SPECT and (18)FDG-PET in patients with indeterminate lung lesions to demonstrate that (99m)Tc-MIBI-SPECT may be considered as a valid alternative when ...

The aim of this study is to evaluate whether the technetium-99m sestamibi ((99m)Tc-MIBI) single photon emission computed tomography (SPECT) characteristics of pituitary adenomas might be correlated with cavernous sinus invasion, proliferative potential or the multidrug-resistance (MDR-1) gene product P-glycoprotein (Pgp) expression in pituitary adenomas. Fifteen patients with pituitary adenomas...

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...

To compare the myocardial uptake pattern of 99mTc-labeled methoxyisobutyl isonitrile [( 99mTc] MIBI) and 201TI, planar scintigraphy were performed in both patients with documented coronary artery disease and subjects with a low likelihood of disease. Quantitative analysis was employed using a standard interpolative background subtraction algorithm and a new algorithm modified to better accommod...

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...

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...
