Toraks Bilgisayarlı Tomografi ve Koroner Bilgisayarlı Tomografi Anjiografide Atriyum ve Ventrikül Ölçümlerin Uyumluluğunun Değerlendirilmesi

Öz

Amaç: Bu çalışmada koroner bilgisayarlı tomografi anjiyografi (BTA) ve kontrastlı toraks bilgisayarlı tomografi (BT) görüntülerinde kalp odalarının çap ve alan ölçümlerinin tutarlılığını değerlendirmeyi amaçladık. Materyal ve Metot: Ağustos 2016 ile Ağustos 2019 tarihleri arasında 6 aylık bir süre içerisnde torasik BT ve koroner BTA ile tetkik edilen 30 hasta çalışmaya dahil edildi. Maksimum sol atriyum alanı, ön-arka ve transvers sol atriyum çapı, sağ atriyum transvers çapı, sağ ve sol ventrikül transvers çapları iki gözlemci tarafından ölçüldü. Gözlemciler arası ve gözlemci içi uyum, sınıf içi korelasyon katsayıları kullanılarak hesaplandı. Bulgular: Kalp odacıklarının kontrastlı toraks BT ve koroner BTA ölçümlerinin mükemmel uyumlu olduğu bulundu. Hem sol atriyal aksiyal alanı hem de ön-arka çapı, koroner BTA görüntülerinde ve toraks BT’de yüksek tekrarlanabilirlik ile değerlendirildi. Sonuç: Bildiğindiği kadarı ile bu çalışma, toraks BT ve koroner BTA'da kalp odalarının çapının ve alanının ölçümünü ve birbirleriyle karşılaştırılmasını gösteren ilk çalışmadır. Yüksek tekrarlanabilirliği ile toraks BT, kalp odacıklarının değerlendirilmesinde yararlı bir modalite olabilir.

Evaluation of the Compatibility of Atrium and Ventricular Measurements in Thoracic Computerized Tomography and Coronary Computerized Tomography Angiography

Abstract

Objective: We aimed to evaluate the consistency of the measurements of diameter and area of cardiac chambers in coronary computed tomography angiography (CTA) and contrast-enhanced thoracic computed tomography (CT) images. Material and Method: 30 patients who underwent thoracic CT and coronary CTA over a 6-month period between August 2016 and August 2019 were included in the study. Maximum left atrium area, anteroposterior and transverse left atrium diameter, right atrium transverse diameter, right and left ventricular transverse diameters were measured by two observers. Inter-observer and intra-observer agreement were calculated using intraclass correlation coefficients. Results: Contrast-enhanced thoracic CT and coronary CTA measurements of the cardiac chambers were found to be perfectly compatible. Both left atrial axial area and AP diameter were evaluated on coronary CTA images and contrast-enhanced thoracic CT with excellent reproducibility. Conclusion: To our knowledge, this is the first study that shows the measurement of diameter and area of the cardiac chambers in thoracic CT and coronary CTA and comparing them with each other. Thoracic CT, with its high reproducibility, could be a useful tool in evaluation of cardiac chambers
