Clinical image quality assessment in panoramic radiography

Year 2014, Volume: 4 Issue: 3, 126 - 132, 15.12.2014

Abstract

Aim: This study was performed to assess the quality of panoramic radiographs obtained and to identify those errors directly responsible for diagnostically inadequate images. 

Materials and Methods: This study consisted of 150 panoramic radiographs obtained from the Department of Oral Diagnosis and Radiology. All projections were made with the same radiographic equipment (Morita Veraviewwopcs model 550 (Kyoto-Japan) with the maximum KVP of 80, mA=12, monitor 17 inch TFT LCD, 100-240 VAC 60/50 Hz, Global Opportunities). The images were exported and saved in Joint Photographic Experts Group (JPEG) file and no adjustment of contrast, brightness and magnification was performed. Two oral and maxillofacial radiology specialist evaluated the images using the Clinical Image Quality Evaluation Chart and classified the overall image quality of the panoramic radiographs and evaluated the causes of imaging errors.

Results: The mean (SD)score was 79.69±14.87. In the classification of the overall image quality, 28 images were deemed ‘optimal for obtaining diagnostic information’, 80 were ‘adequate for diagnosis’, 37 were ‘poor but diagnosable’, and 5 were ‘unrecognizable and too poor for diagnosis’. The results of the analysis of the causes of the errors in all the images were as follows: 103 errors in positioning, 15 in processing, 4 due to radiographic unit, and none of them was due to anatomic abnormality.

Conclusion: The positioning errors found on panoramic radiographs were relatively common in our study. The quality of panoramic radiographs could be improved by careful attention to patient positioning.

Panoramik radyografide kalite değerlendirmesi

Year 2014, Volume: 4 Issue: 3, 126 - 132, 15.12.2014

Abstract

Amaç: Bu çalışmada elde edilen panoramik radyografilerin kalitesinin değerlendirilmesi ve tanı için yetersiz görüntülere neden olan hataların tespiti amaçlanmıştır. 

Yöntem: Çalışmada Oral Diagnoz ve Radyoloji AD arşivlerinde yer alan 150 adet panoramik radyografi incelenmiştir (Morita Veraviewwopcs model 550 ,Kyoto-Japan, en yüksek KVP of 80, mA=12, monitör 17 inç TFT LCD, 100-240 VAC 60/50 Hz, Global Opportunities). Bütün grafiler aynı radyografik ekipman ile yapılmıştır. Görüntüler JPEG (Joint Photographic Experts Group ) dosyası olarak kaydedilmiş ve kontrast, parlaklık ve büyütme ve data kompresyonu açısından herhangi bir düzeltme yapılmamıştır. Elde edilen görüntüler iki maksillofasiyal radyoloji uzmanı tarafından Klinik Görüntü Kalitesi Değerlendirme Çizelgesi kullanarak değerlendirilmiş, panoramik radyografide genel görüntü kalitesi sınıflandırılmış ve görüntüleme hatalarının nedenleri incelenmiştir. Veri tablolama ve tanımlayıcı istatistik SPSS 15.0 yazılımı (SPSS Inc., Chicago. IL., USA) kullanılarak yapılmıştır. 

Bulgular: Klinik Görüntü Kalitesi Değerlendirme Çizelgesi ortalama değeri 79.69±14.87 olarak ölçülmüştür. Görüntü kalitesinin skorlamasında 28 görüntünün tanısal bilgide en iyi görüntü kalitesine sahip olduğu, 80 görüntünün tanı için yeterli olduğu, 37 görüntünün tanı koyma açısından zayıf ama teşhis edilebilir olduğu ve 5 görüntünün tanı için yetersiz olduğu belirlenmiştir. Tüm görüntülerde izlenen hataların nedenlerinin analiz sonuçları şu şekildedir: 103 görüntüde konumlandırma hatası, 15 görüntüde işlem sırasında oluşan hata, 4 görüntüde ünite kaynaklı hata görülmüş ancak hiçbir radyografide anatomik abnormaliteye bağlı hata izlenmemiştir. 

Sonuç: Panoramik radyografinin görüntüleme işlemi sırasında hasta konumlandırma tarafından kaynaklanan hatalar çalışmamızda en yaygın izlenen hata tipi olarak bulunmuştur. Ancak daha fazla hasta grubu ile farklı radyografik yöntemler kullanılarak görüntü kalitesinin değerlendirildiği çalışmalara ihtiyaç duyulmaktadır.
