In conclusion MDCT split-bolus protocol provides an optimal pancreatic enhancement, significantly greater than the enhance- ment of standard MDCT on PPP which confers an advantage for the detection and staging of pancreatic tumors.

Özet

The aim of this study is to quantitatively assess radiation com- ma, and pancreatic enhancement by split-bolus intravenous in- jection of contrast material using 64-slice CT. Single-pass split- bolus MDCT of the chest and abdomen was performed in 37 patients (female: 18, male: 9; mean age, 66.1±14.2 years; range 17-80 years) without pancreatic disease. Regions of interest in the pancreatic head, body and tail were drawn, and mean at- tenuation values for pancreatic parenchymal phase (PPP) of the standard MDCT protocol and split-bolus were calculated. P<0.05 was considered statistically significant. Mean effective dose by split-bolus was measured. In all MDCT examinations split-bolus protocol allowed acquisition of optimal images. Mean pancreatic enhancement was higher by split-bolus with respect to PPP of standard triphasic MDCT (131.35 HU±20.63 vs 126.1 HU±20.01). Reduction of dose using MDCT split-bolus was approximately 17%. In conclusion MDCT split-bolus protocol provides an optimal pancreatic enhancement, significantly greater than the enhance- ment of standard MDCT on PPP which confers an advantage for the detection and staging of pancreatic tumors.

Abstract

Bu çalışmanın amacı, bölünmüş-bolus intravenöz kontrast mad- de kullanılarak yapılan 64 kesitli BT ile pankreatik artışı ve rad- yasyon dozunu kantitatif olarak değerlendirmektir. Pankreatik bir hastalığı olmayan 37 hastaya (kadın: 18, erkek: 9, ortalama yaş: 66,1±14,2 yaş, aralık 17-80 yaş) göğüs ve abdomen tek geçiş bölünmüş-bolus MDBT uygulandı. Pankreas başı, gövdesi ve kuy- ruğundaki ilgili bölgeler değerlendirildi ve standart MDBT proto- kolünün pankreatik parankimal faz (PPF) için ortalama zayıflama değerleri ve bölünmüş-bolus dozları ölçüldü. P<0.05 değeri ista- tistiksel olarak anlamlı kabul edildi. Bölünmüş-bolus uygulama- sının ortalama efektif dozu ölçüldü. Tüm MDBT incelemelerinde bölünmüş-bolus protokolü kaliteli görüntülere izin verdi. Ortala- ma panreatik artış PPF için bölünmüş-bolus uygulamasında stan- dart trifazik MDBT e göre daha yüksekti (131,35 HU±20,63 vs 126.1 HU±20.01). bölünmüş bolus dozlu MDBT ‘de dozda azalma yaklaşık olarak %17 idi. Sonuç olarak, bölünmüş-bolus protokol- lü MDBT optimal pankreatik artış sağlar, pankreatik parankimal faz için özellikle standart MDBT değerlendirmesine göre önemli ölçüde üstünlük sağlar ve pankreas tümörlerinin belirlenmesi ve evrelemesi için avantajlıdır.
