Abstract

Amaç: Koroner arter hastalığı kalbin duvar hareketlerini ve fonksiyonlarını etkilemektedir. Günümüzde kalp fonksiyonları genellikle ekokardiyografi ile değerlendirilmektedir. Bu çalışmada sol ventrikül duvar hareket kusurlarının ve ejeksiyon fraksiyonunun EF değerlendirilmesinde Kardiyak Manyetik Rezonans Görüntüleme KMRG ’nin duyarlılığı araştırılmıştır. Gereç ve Yöntem: Çalışmamızda koroner arter hastalığı saptanan ve ekokardiyografik incelemeleri yapılmış 30 hasta ile 20 sağlıklı olguda K-MRG görüntülenmesi yapıldı. Kısa aks, 4 boşluk ve 2 boşluk görüntüler alındıktan sonra sine K-MRG görüntüler, retrospektif ve EKG tetiklemeli olarak parelel görüntüleme tekniği eşliğinde bir kalp siklusunda ortalama 20 görüntü alabilen True-FISP sekansı ile alındı. Görüntüler sol ventrikül EF ve duvar hareketleri değerlendirmesi için ARGUS programına aktarıldı. K-MRG ve ekokardiyografi sonuçları istatistiksel olarak Student’s-t paired testi ve Pearson korelasyon analizi ile karşılaştırıldı Bulgular: Tüm olgularda K-MRG incelemeleri 20–25 dakika içerisinde başarı ile gerçekleştirildi. Yapılan karşılaştırmalarda kontrol grubunda EF açısından istatistiksel bir fark saptanmadı p>0.05 . Hasta grubunda yapılan karşılaştırılmalarda hem EF değerleri, hem de duvar hareketlerinin skorlanmasında ortalama değerler arasında istatistiksel fark p

The Evaluation Of The Left Ventricular Movement İn The Case Of Coronary Arterial Diseases With Cardiac Magnetic Resonance İmaging

Abstract

Purpose: In case of coronary artery disease CAD , cardiac wall movements and output functions are being affected. Cardiac funtions are generally evaluated with echocardiography nowadays. In this study, the effectiveness of cardiac magnetic resonance imaging C-MRI in the left ventricular wall movement abnormality and ejection fraction EF has been evaluated and compared with echocardiography. Materials and Methods: In our study, 30 patients with CAD and 20 cases as control group were examined with echocardiography and C-MRI within the same day. After obtaining short axis, 4 chamber and 2 chamber morphologic images, cine C-MRI was taken with True-FISP sequence using parellel images and retrospective ECG triggered technique which has capability of 20 images in one cardiac cycle. After transferring the images to workstation, left ventricular EF and wall movements were evaluated using ARGUS programme which is dedicated to cardiac functions. The results of C-MRI and echocardiography were statistically compared with Students-t paired test and Pearson correlation analysis. Results: All of the C-MRI examinations were performed succesfully within 20-25 minutes. There were no statistical difference in comparison of the EF between echocardiography and C-MRI in control group. But in the patient group, the average value of the EF and wall movement scores were statistically different from each other P
