Düşük doz üriner BT’de saptanan insidental patolojik bulgular

Abstract

Amaç: Günümüzde, üriner sistem taş hastalığının değerlendirilmesinde düşük doz üriner sistem bilgisayarlı tomografi incelemesi yaygın olarak kullanılmaktadır. Bu incelemelerde klinik açıdan önemli insidental bulgulara rastlanmaktadır. Bu bulgular hakkında bilgi sahibi olunması ve bu bulguların yönetimi, radyologlar ve klinisyenler için önemlidir. Bu çalışmada, düşük doz üriner sistem bilgisayarlı tomografi incelemesi ile insidental olarak saptanan patolojik bulguların değerlendirilmesi amaçlanmıştır. Yöntem: Çalışmaya, Ağustos 2017–Mart 2018 tarihleri arasında Gazi Üniversitesi Tıp Fakültesi Radyoloji Anabilim Dalı Bilgisayarlı Tomografi ünitesinde, 64-kesit ve 384-kesit (2x192) bilgisayarlı tomografi cihazlarında düşük doz üriner sistem bilgisayarlı tomografi incelemesi elde olunan 398 erişkin olgu dahil edildi. Elde olunan incelemeler retrospektif olarak değerlendirildi. İncelemelerde saptanan insidental patolojik bulgular ilk olarak ait oldukları organlara göre ana gruplara ayrıldı. Ardından her organa ait patolojiler kendi içinde alt gruplara ayrılıp değerlendirildi. Bulgular: Karaciğer, safra kesesi, ince ve kalın bağırsaklar, mezenter, abdominal ana vasküler yapılar, kemikler, iç genital organlar ve diğer organ gruplarında insidental patolojik bulgular saptanırken; pankreas ve safra yollarında insidental patolojik bulgu saptanmadı. En sık olarak, olguların %56’sında kemik yapılarda insidental patolojik bulgu saptandı. Sonuç: Düşük doz üriner sistem bilgisayarlı tomografi incelemelerinde, klinik açıdan önemli olabilecek insidental patolojik bulgular saptanmaktadır. Bu bulgular hakkında bilgi sahibi olunması radyologların tanısal duyarlılığını artırırken, radyologlar ve klinisyenlere bu bulguların yönetimi konusunda kolaylık sağlayacaktır.

Incidental pathological findings detected by low-dose urinary CT

Abstract

Objective: Currently, low-dose computed tomography scans of the urinary system are widely used in the evaluation of urinary system stone disease. These scans often reveal clinically significant incidental findings. Understanding and managing these findings are crucial for both radiologists and clinicians. This study aimed to evaluate pathological findings incidentally detected by low-dose CT scans of the urinary system. Methods: This study included 398 adult cases whose low dose urinary system computed tomography scans were obtained using 64-slice and 384-slice (2x192) computed tomography devices at the Compu-ted Tomography Unit of the Radiology Department of Gazi University Faculty of Medicine between August 2017 and March 2018. The scans were evaluated retrospectively. Incidental pathological fin-dings were first divided into main groups according to their organs. Pathologies related to each organs were then further subdivided and evaluated. Results: Incidental pathological findings were detected in liver, gallbladder, small and large intestines, mesentery, abdominal main vessels, bony structures, internal genitalia, and the other organ groups while no incidental pathological findings were detected in the pancreas and bile ducts. Most frequently, inci-dental pathological findings were detected in bony structures in 56% of cases. Conclusion: Low-dose urinary system computed tomography scans reveal incidental pathological fin-dings that may be clinically significant. Knowledge of these findings enhances the diagnostic accuracy of radiologists and facilitates their management for both radiologists and clinicians.
