Tamamlayıcı Görüntüleme Yöntemi: Raster-stereografinin Kullanılabilirliği ve Radyografi ile Validasyonu

Amaç: Raster-stereografi (RST) tekrarlayan radyasyon dozlarından kaçınmak için radyografik görüntülemeye alternatif olarak tasarlanmıştır. Bu çalışmanın amacı adölesan idiyopatik skolyoz hastalarında, retrospektif olarak çekilmiş olan RST’yi radyografi ile karşılaştırılmak ve sagital, koronal ve horizontal düzlem parametrelerinde geçerlilik onayını (validasyon) belirlemektir. Gereç ve Yöntem: Daha önce çift düzlemli radyografi (EOS) ile eş zamanlı RST çekimleri yapılmış hastalar retrospektif olarak tarandıktan sonra 31 hasta çalışmaya alındı. EOS ve RST’de uzunluk (gövde uzunluğu), pelvik parametreler (pelvik obliklik, pelvik eğiklik, sakral eğim, pelvik inklinasyon), sagital düzlem (torakal kifoz, lomber lordoz, T1 eğim, sagital imbalans), koronal düzlem (ana Cobb açısı, orta hat apikal deviasyon, T1 eğiklik) ve horizontal düzlem (rotasyon miktarı) parametreleri ölçüldü ve değerler karşılaştırılarak birbirleri ile ilişkileri incelendi. Bulgular: Gövde uzunluk ölçümünde, RST ve EOS arasında yüksek ilişki bulundu (r=0,940; p

Complementary Imaging Method: Applicability of Raster-stereography and Validation by Radiography

Objectives: Raster-stereography (RST) has been developed as an alternative to plain radiography to avoid repeated radiation doses. The aim was to compare retrospectively evaluated RST with radiography in adolescent idiopathic scoliosis and to determine its validation in sagittal, coronal and axial plane parameters. Materials and Methods: After retrospective evaluation of the patients with biplanar radiography (EOS) and RST scans, 31 patients were included. Height (trunk height), pelvic parameters (pelvic obliquity, pelvic tilt, sacral slope, pelvic inclination), sagittal plane (thoracic kyphosis, lumbar lordosis, T1 slope, sagittal imbalance), coronal plane (main Cobb angle, apical deviation, T1 tilt) and axial plane (rotation) parameters were measured in EOS and RST, and the values were compared for examining their relationships with each other. Results: In trunk length measurements, a high correlation was observed between RST and EOS (r=0.940; p
