Abstract

OBJECTIVE: The aim of this study is to determine the radiation dose parameters of renal computed tomography angiography (RCTA) scans in kidney transplant donors.MATERIAL AND METHODS: RCTA scans obtained between July 2017 and December 2019 in a tertiary reference hospital were included in this study whose ethics committee approval was obtained retrospectively. CT radiation dose parameters were obtained from the picture archiving and communication system. Volume CT dose index (CTDIvol) and dose length product (DLP) values were recorded from the patient dose reports. Effective dose (ED) and scan length (SL) were calculated.RESULTS: Of the 142 patients who underwent RCTA, 54 % (n = 76) were men and 46 % (n = 66) were women. The mean age of the patients was 43.8 ± 12.5. The second quarter (median) of total DLP and ED values of RCTA scans were 835 mGy.cm and 12.5 mSv, respectively. The mean SL value of unenhanced, arterial, venous and late phase series were 31.4 ± 3, 21.9 ± 3, 32.1 ± 4.5 and 22.7 ± 4.7 cm, respectively.CONCLUSIONS: In this study, radiation dose parameters of RCTA scans were lower than the relevant literature.

Özet

AMAÇ: Bu çalışmada amaç, böbrek nakli vericilerinin renal bilgisayarlı tomografi anjiyografi (RBTA) tetkiklerinin radyasyon dozunu saptamaktadır.GEREÇ VE YÖNTEM: Etik kurul onayı retrospektif olarak alınan bu çalışmaya 3. basamak hastanede Temmuz 2017 ve Aralık 2019 tarihleri arasında çekilen RBTA tetkikleri dahil edildi. Görüntü arşivleme iletişim sisteminden, BT tetkiklerinin hacimsel BT doz indeksi (Volume CT dose index, CTDIvol) ve tarama alanı boyunca alınan doz (dose length product, DLP) değerleri hasta doz raporlarından kaydedildi. Etkin doz (ED) ve tarama uzunluğu (TU) hesaplandı.BULGULAR: RBTA çekilmiş 142 hastanın % 54 (n=76)'ü erkek, % 46 (n=66)'sı kadındı. RBTA'sı elde edilen hastaların ortalama yaşı 43,8±12,5'dir. RBTA tetkiklerinin ikinci çeyrek (ortanca) toplam tarama alanı boyunca alınan doz (DLP) ve ED değerleri sırasıyla 835 mGy.cm ve 12,5 mSv'dir. Kontrastsız, arteryel, venöz ve geç faz çekimlerin ortalama TU değerleri sırasıyla 31,4±3, 21,9±3, 32,1±4,5 ve 22,7±4,7 cm'dir.SONUÇ: Çalışmamızda RBTA tetkiklerinin radyasyon dozu parametreleri literatüre göre daha düşüktür.
