Abstract

Introduction:Multiple myeloma (MM) is a plasma cell neoplasm, characterized by plasma cell infiltration inside the bone marrow, secretion of monoclonal immunoglobulin (paraprotein), and end organ damage including lytic lesions in the bones. About 80-90% of myeloma patients suffer from osteolytic lesions during the course of the disease. 18F-FDG PET/CT is an imaging technique capable to detect active disease in patients in multiple myeloma (MM) and can be helpful in staging and prognosis. However, its routine use is still hampered by several factors, including high cost, reimbursement issues, lack of cost-effectiveness studies and limited availability. 99mTc-sestamibi (MIBI) has also been proposed as a potential tracer in MM evaluation and is more accessible with lower costs. The aim of this study was to compare these two imaging modalities at staging disease and their relation with clinical data.

Abstract

OBJECTIVE: To investigate the pattern of perfusion abnormalities in ictal and interictal brain perfusion SPECT images (BSI) from patients with temporal lobe epilepsy (TLE). METHOD: It was acquired interictal and ictal BSI from 24 patients with refractory TLE. BSIs were analyzed by visual inspection and statistical parametric mapping (SPM2). Statistical analysis compared the patients group to a control group of 50 volunteers. The images from patients with left-TLE were left-right flipped. RESULTS: It was not observed significant perfusional differences in interictal scans with SPM. Ictal BSI in SPM analysis revealed hyperperfusion within ipsilateral temporal lobe (epileptogenic focus) and also contralateral parieto-occipital region, ipsilateral posterior cingulate gyrus, occipital lobes and ipsilateral basal ganglia. Ictal BSI also showed areas of hypoperfusion. CONCLUSION: In a group analysis of ictal BSI of patients with TLE, voxel-wise analysis detects a network of distant regions of perfusional alteration which may play active role in seizure genesis and propagation.
