Abstract

Objective: Speckle tracking is a new imaging modality capable of providing information about myocardial motion in all three directions: longitudinal, circumferential and radial. There are many software packages with their unique tracking algorithms and user interfaces in the market. We aimed to evaluate the feasibility of QLAB software in clinical practice and speckle based myocardial velocities in healthy subjects. Methods: Thirty-two subjects were enrolled in the study. Images from apical four-chamber, apical two-chamber, parasternal short-axis (mitral valve-apical levels) views were acquired and analyzed offline with QLAB. We measured speed and velocity data in longitudinal, circumferential and radial directions. Time percent of these events were also calculated. In the final data analysis 825 of 832 segments (99.2%) were included. Mann Whitney U, Student’s t and Kendall’s tau-b coefficient tests were used for statistical analysis. Results: We determined that circumferential speed was significantly higher (p

Özet

Amaç: Benek izleme (speckle tracking), miyokart hareketinin tüm yönleri hakkında (longitüdinal, sirkümferansiyal ve radiyal) bilgi veren yeni bir görüntüleme yöntemidir. Bu amaçla kendi takip algoritmaları ve kullanıcı arabirimlerine sahip birçok yazılım piyasaya sunulmuştur. Biz bu çalışmada, QLAB yazılımının klinik uygulamada kullanılabilirliğini ve sağlıklı bireylerde miyokart hızlarını benek izleme yöntemiyle değerlendirmeyi amaçladık. Yöntemler: Çalışmaya 32 sağlıklı birey dahil edildi. Apikal 4 oda, apikal 2 oda ve parasternal kısa eksen (mitral kapak ve papiller kas seviyesi) görüntüleri her bireyde alınarak QLAB yazılımıyla incelendi. Longitüdinal, sirkümferansiyal ve radiyal yöndeki hız ve vektöriyel hız verileri ölçüldü. Bu olayların gerçekleştiği zaman, yüzde olarak hesaplandı. Görüntülenmeye çalışılan 832 segmentten 825’i (%99.2) değerlendirmeye alındı. İstatistiksel analizde Mann Whitney U, Student t ve Kendall’s tau-b katsaysı testleri kullanıldı. Bulgular: Sirkümferansiyal hız her iki parasternal kısa eksen kesitlerinde de radiyal hız vektöründen daha fazlaydı (p
