Malign Plevral Mezotelyoma F-18 FDG PET/BT, BTve Teknesyum-99m Aerosol Sintigrafisi BulgularınınKarşılaştırılması

Amaç: Bu çalışmanın amacı, malign plevral mezotelyoma hastalarında F-18 floro-deoksiglikoz (FDG) pozitron emisyon tomografi/bilgisayarlı tomografi (PET/BT)’den elde edilen $SUV_{max}$ değeri ile DTPA aerosol sintigrafisiyle hesaplanan kapiller epitelyal permeabilite değeri arasındaki ilişkiyi incelemektir. Gereç ve Yöntemler: Bu çalışmaya, malign plevral mezotelyoma tanısı almış ve PET/ BT görüntülemesi yapılmış 22 (13’ü erkek, 9’u kadın) hasta dahil edildi. Malign plevral mezotelyomalı hastalarda parankim hasarını belirlemek amacıyla teknesyum-99m DTPA aerosol sintigrafisi yapıldı. Malign plevral mezotelyoma tutulum lokalizasyonları üst, orta ve alt olmak üzere üç alana ayrılarak her alanın tümör $SUV_max$/karaciğer $SUV_{max}$ ($SUV_{oranı}$) ile plevral kalınlaşma değerleri ve kapiller epitelyal permeabilite değerleri arasındaki ilişki Pearson korelasyon testiyle incelendi. Bulgular: Her üç alanda $SUV_{oranı}$ ile plevral kalınlaşma değerleri arasında pozitif korelasyon (p

Comparison of Malign Pleural Mesothelioma F-18 Fluorodeoxy Glucose Positron Emission Tomography/ Computed Tomography, Computed Tomography and Teknetium-99m Aerosol Scintigraphy Findings

Objective: The aim of this study was to examine the relationship between the standard uptake value $(SUV)_{max}$ value obtained from fluorodeoxy glucose positron emission tomography/computed tomography (PET/CT) and the capillary epithelial permeability (CEP) value calculated by diethylenetriamine pentacetic acid (DTPA) aerosol scintigraphy in patients with malignant pleural mesothelioma (MPM). Material and Methods: Twenty-two MPM diagnosed patients who underwent PET/CT imaging were included in this study. In MPM patients Tc-99m DTPA Aerosol Scintigraphy was performed to determine parenchymal damage. MPM involvement localizations were divided into three areas as upper, middle, and lower. The relationship between tumor$SUV_max$/liver$SUV_{max}$ ($SUV_ratio$), pleural thickening values, and CEP values of each area was examined. Results: In all areas, a positive correlation was found between $SUV_ratio$ and pleural thickening values (p
