Imaging of the urinary tract and its surrounding tissue still remains challenging, since standard imaging in the urological operation room consists of fluoroscopy and plain X-rays. The combination of a ceiling-mounted X-ray system and a new urological intervention table now allows cross-sectional imaging and 3D reconstruction to be performed in the endourological operation room (Urological Dyna-CT).
The imaging quality of the Artis Zee Ceiling (Siemens Medical Solutions, Erlangen, Germany) was assessed using slice images of an ex vivo pig kidney model prepared with artificial stones (plaster of Paris). We compared the image quality of three different examination protocols with this model. 3D reconstruction quality was illustrated by means of retrograde filling of one pig`s urinary tract with a diluted contrast medium.
Interventional stone detection and localization is possible with a 5 s low-dose Urological Dyna-CT. Detailed imaging of the collecting system by retrograde pyelography is possible with a high image quality.
The combination of an Artis Zee(®) Ceiling (Siemens Medical Solutions, Erlangen, Germany) with our newly developed urological intervention table we call the Urological Dyna-CT. In addition to such standard procedures as fluoroscopy or plain X-rays, cross-sectional imaging and 3D reconstruction of the urinary tract are possible and provide fast and excellent urological imaging.
由于泌尿外科手术室的标准成像包括荧光透视和普通X线检查,因此对尿路及其周围组织进行成像仍然具有挑战性。天花板式X线系统与新型泌尿外科介入手术台相结合,现在可以在腔内泌尿外科手术室(泌尿外科动态CT)中进行断层成像和三维重建。
使用用人造结石(巴黎石膏)制备的离体猪肾模型的切片图像,评估Artis Zee Ceiling(西门子医疗解决方案公司,德国埃尔兰根)的成像质量。我们用该模型比较了三种不同检查方案的图像质量。通过用稀释的造影剂逆行充盈一头猪的尿路来说明三维重建质量。
采用5秒低剂量泌尿外科动态CT可以进行介入性结石检测和定位。通过逆行肾盂造影对集合系统进行详细成像,可以获得高质量的图像。
将Artis Zee(®)Ceiling(西门子医疗解决方案公司,德国埃尔兰根)与我们新开发的泌尿外科介入手术台相结合,我们称之为泌尿外科动态CT。除了荧光透视或普通X线检查等标准程序外,还可以对尿路进行断层成像和三维重建,并提供快速且出色的泌尿外科成像。
