Farklı Saklama Koşulları ve Bekletme Sürelerinin Işıkla Uyarılabilen Fosfor (PSP) Plak Görüntülerindeki Ortalama Gri Değere (OGD) Etkisi
Öz
Amaç: Bu çalışmanın amacı, ışıkla uyarılabilen fosfor (Photostimulable Storage Phosphor, PSP) plakalarının ışınlama-tarama süreçleri arasındaki farklı tarama gecikmeleri (bekletme süresi) ve saklama koşullarının görüntülerindeki Ortalama Gri Değer (OGD) değişimine etkisini değerlendirmekti.
Gereç ve Yöntem: Saklama koşuluna göre oluşturulan dört grupta [Tek Kılıf Aydınlık (TKA), Tek Kılıf Karanlık (TKK), Tek Kılıf Karton Aydınlık (TKKA), Tek Kılıf Karton Karanlık (TKKK)] farklı bekletme sürelerinde toplam 40 görüntü elde edildi. ImageJ (National Institutes of Health, Bethesda, MD) programı ile görüntülerin OGD’leri ölçüldü. Saklama koşullarını karşılaştırmak için tek yönlü, bekletme sürelerini karşılaştırmak için iki yönlü tekrarlı ölçümlü ANOVA testleri kullanıldı. Her bir gruptaki bekletme süreleri ile 0 dk. (altın standart) OGD’lerin karşılaştırılması için eşleştirilmiş örneklemler t-testi uygulandı. p<0.05 istatistiksel olarak anlamlı kabul edildi.
BULGULAR: On dk. ile altın standart arasındaki OGD farkı sadece TKA grubunda istatistiksel olarak anlamlıydı (p<0.05). Herhangi bir bekletme süresinde, saklama koşulları OGD’leri arasında istatistiksel olarak anlamlı fark yoktu (p>0.05). Altın standart dışındaki diğer bekletme süreleri karşılaştırıldığında, 24 saat bekletme süresi ile diğer bekletme süreleri OGD’leri arasında istatistiksel olarak anlamlı fark vardı (p<0.05).
Sonuç: Plakların ışınlama sonrası karanlık ortamda ve karton koruyucu içinde 10 dk.’yı geçmeyen bekletme süresi ile bekletilmesinin OGD’ye etkisi önemsizdi. Sadece plastik bariyerde ve 24 saat sürede bekletilen plakların görüntülerdeki OGD artışı dikkat çekiciydi.

The Effect of Different Storage Conditions and Scan Delays on the Mean Gray Value (MGV) on Photostimulable Storage Phosphor (PSP) Plate Images
Öz
Objective: The aim of this study was to evaluate the effect of different scan delays (waiting time) and storage conditions between exposure-scanning processes of Photostimulable Storage Phosphor (PSP) plates on the Mean Gray Value (MGV) change on their images.
Materials and Method: A total of 40 images obtained at different waiting times in four groups [Single Sheath Light (SSL), Single Sheath Dark (SSD), Single Sheath Cardboard Light (SSCL), Single Sheath Cardboard Dark (SSCD)] created according to storage conditions. MGVs of the images were measured with ImageJ (National Institutes of Health, Bethesda, MD) program. To compare the storage conditions the one-way and to compare the waiting times the two-way repeated measure ANOVA tests were used. Paired samples t-test was applied to compare the waiting times and 0-min. MGVs in each group. p<0.05 was considered statistically significant.
RESULTS: The MGV difference between 10-min. and the gold standard was statistically significant only in the SSL group (p<0.05). There was no statistically significant difference between storage conditions’ MGVs at any waiting time (p>0.05). When the other waiting times
except the gold standard were compared, there was a statistically significant difference between the 24-hour waiting time and the other waiting times’ MGVs (p<0.05).
Conclusion: The effect of keeping the plates in the dark and in a cardboard protector with a waiting time not exceeding 10-min., after the exposjure, on MGV was insinificant. The MGV increase of the images of the plates kept only in the plastic barrier and for 24-hour was remarkable.
