Toraks Bilgisayarlı Tomografi Kantitatif Ölçüm Parametreleri ile Solunum Fonksiyon Testi Arasındaki Korelasyonun İncelenmesi: Retrospektif Çalışma

Amaç: Pulmoner fonksiyonel ve hacimsel değerlendirme rutin olarak solunum fonksiyon testi (SFT) ile yapılmaktadır. Ancak bilgisayarlı tomografi (BT) görüntülemede hacimsel değerlendirme de mümkündür. Bu çalışmanın amacı, SFT ile BT hacimsel bulguları arasındaki ilişkiyi incelemektir. Gereç ve Yöntem: Nisan 2017 ile Mayıs 2020 tarihleri arasında toraks BT (parankimal hastalığı olmayan) ve SFT yapılan toplam 69 hasta (34 erkek, 35 kadın) retrospektif olarak incelendi. Optimum kalitede görüntüler ve PFT incelemeleri kaydedildi. BT’de, her iki akciğerin hacmi ve yoğunluğu ile toplam akciğer hacmi (TLV) ve toplam akciğer yoğunluğu (TLD) hesaplandı. BT ile değerlendirme için bir saniyedeki zorlu ekspiratuvar hacim (FEV1), zorlu vital kapasite (FVC), FEV1/FVC oranı kaydedildi. Bulgular: Toplam 69 hastada (34 erkek, %49,3; 35 kadın, %50,7) ortalama yaş 55±14,56 yıl, FEV1=2.12±0,87, FVC=2,92±1,05, FEV1/FVC oranı=72,19±13,07 sağ akciğer hacmi=2118,06±662,36, sağ akciğer yoğunluğu=-806,8±68,16, sol akciğer hacmi=1755,35±605,02, sol akciğer yoğunluğu=-774,80±248,98, TLV=3820±1272,35 ve TLD=-1597,17±295,70 idi. FEV1, FVC ve FEV1/FVC oranı bilateral (sağ ve sol) akciğer hacmi ve yoğunluğu ile pozitif korelasyon gösterdi (p

A Correlation Between Quantitative Measurement Parameters of Thorax Computed Tomography and Pulmonary Function Test: A Retrospective Study

Aim: Pulmonary functional and volumetric evaluation is routinely performed with pulmonary function test (PFT). However, volumetric evaluation is also possible in computed tomography (CT) imaging. The aim of this study is to examine the relationship between PFT and CT volumetric findings. Materials and Methods: Between April 2017 and May 2020, a total of 69 patients (34 males, 35 females) having thorax CT (without any parenchymal disease) and PFT were studied retrospectively. The images and PFT examinations with an optimum quality were enrolled. In CT, the volume and density of both lungs as well as total lung volume (TLV) and total lung density (TLD) were calculated. Forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), and FEV1/FVC ratio were recorded for the assessment with CT. Results: In a total of 69 patients (34 male, 49.3%; 35 female, 50.7%), the mean age was 55±14.56 years, FEV1=2.12±0.87, FVC=2.92±1.05, FEV1/FVC ratio=72.19±13.07, right lung volume=2118.06±662.36, right lung density=-806.8±68.16, left lung volume=1755.35±605.02, left lung density=-774.80±248.98, TLV=3820±1272.35 and TLD=-1597.17±295.70. FEV1, FVC and FEV1/FVC ratio showed a positive correlation with bilateral (right and left) lung volume and density (p
