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...

OBJECTIVE To determine the frequency of the types of parathyroid gland hyperplasia and the sensitivity of sestamibi-(99m)Tc (MIBI) scintigraphy and ultrasonography (US) of patients with secondary hyperparathyroidism (SHPT) due to chronic renal failure. MATERIAL AND METHODS We studied 43 patients with SHPT (26 females and 17 males with age range of 27-75 years). Blood tests were performed to d...

Multidrug resistance (MDR) is a major problem in lung cancer. Tc-99m methoxyisobutyl isonitrile (MIBI) has been demonstrated to be a non-invasive marker to diagnose MDRI related P-glycoprotein (Pgp) and multidrug resistance-associated protein (MRP) expression in various solid tumors. The aim of this study was to evaluate the relationship between the degree of Tc-99m MIBI uptake and its retentio...

OBJECTIVES The pioneering performance of gamma probe-assisted surgery (GPAS) for brain tumors, aiming not only an improvement of tumor detection, but mainly assurance of its complete removal and the study of the usual distribution of the 99mTc-MIBI in the brain SPECT of normal individuals. METHOD Patient's informed consent and demonstration of the tumor by the preoperative MIBI SPECT were the...

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...

We report a case of a young Indian male who had an incidental abnormal focal uptake of 99mTechnetium-MIBI (Methoxy Isobutyl Isonitrile) in the right lobe of thyroid while undergoing 99mTc-MIBI myocardial perfusion gated SPECT (Single Photon Emission Computed Tomography) imaging as a part of his myocardial ischemia status evaluation. This focal uptake was eventually detected to be a malignant th...

UNLABELLED Technetium-99m methoxy-isobutylisonitrile (Tc-99m MIBI) is a routinely used radiopharmaceutical for myocardial perfusion scintigraphy (MPS). It is also a tumor seeking agent. Here, we present a case of 51 year old male who underwent Tc-99m MIBI myocardial perfusion study due to permanent chest pain after coronary angiography. Abnormal MIBI uptake in the thorax was detected in the raw...

Two radiopharmaceuticals, Tc-99m-MIBI (MIBI) and Tc-99m-Tetrofosmin (Tfos), are currently used for in vivo non-invasive monitoring of the MultiDrug Resistant (MDR) status of tumours. As gliomas are highly multidrug resistant, it is expected that the tracers would be poorly retained in those cells, but the in vivo and in vitro studies to date have shown that Tfos was highly retained in malignant...

OBJECTIVE To evaluate the usefulness of (99m)Tc-2-Methoxy-Isobutyl-Isonitrile Single Photon Emission Computed Tomography (MIBI-SPECT) for assessing anterior mediastinal mass, and distinguishing the grade of malignancy of thymic epithelial tumors to offer guidance for decision making. METHODS From January 2006 to November 2009, 31 consecutive patients with an anterior mediastinal mass at CT we...

bone involvement. Destruction is mediated through normal osteoclasts, which respond to local osteoclast-activating microenvironment [7]. Technetium-99m 2methoxyisobutylisonitrile (TC-99m MIBI) is a lipophilic agent that accumulates within living malignant cells due to the higher transmembrane electrical potential as a consequence of the higher metabolic rate than in the surrounding normal cells...
