Imaging Features of Chest Wall Mass in the Hybrid Imaging Modalities: SPECT/CT and PET/CT

Abstract

Background: The chest wall tumors are rare lesions thus there are limited literature data about the radiologic appearance of these tumors and no previous study exists about the diagnostic performance of the functional imaging modalities. Aim of this study is to analyze the diagnostic accuracy of the hybrid imaging modalities: Single photon emission computed tomography/computed tomography (SPECT/CT) and Positron emission tomography/computed tomography (PET/CT) in comparison to the histopathology results of the chest wall tumors. Materials and Methods: Imaging results of the patients (n=20, 7F/13M, mean: 53±21,9 years of age) with the diagnosis of chest wall mass were recorded. Retrospective evaluation of the images were performed by an experienced Nuclear Medicine physician and compared with the histopathology results as gold standard. Results: The lesions of the patients that were involved in this study were mean: 63±33.8 mm and the standardized uptake value (SUVmax) were mean: 13.7±10.8. The imaging/metabolic characteristics of the lesions were considered malign in all the patients included. All the patients diagnosed to have malign neoplasms except two. Conclusion: The hybrid imaging has excellent diagnostic facility in diagnosis of the chest wall neoplasm. Prospective studies about this issue are warranted.
