urinary tract urinary tract imaging virtual endoscopy CT
summary
- Progress in Computer tomography and software allows to obtain images
- of lumen of the urinary system without classical endoscopy. The techni±ue
- known as virtual endoscopy is at its first stage of development now and the
- authors present the method as well as their own preliminary experiences
- related to it.
- Material and methods. 31 patients with suspicion of urinary system lesions
- have been subjected to the CT exam. The image data obtained in this way were
- sent from a working to a satellite station, where the data were processed with
- the "endo" software. In result of the processing, three images were received on
- the screen of the image station: a 3-D reconstruction, a transverse cross-section
- or a front cross-section with a situation of the end of virtual edospcope marked
- on it, and a virtual image of the urinary system.
- Results. Analysis of several types of images gave an excellent possibility to
- make a spacial assessment of the lesions, their identification, grade, situation
- and extent. Virtual endoscopy answered all those ±uestions.
- Conclusions. Virtual images improved the further treatment and made
- radiography more legible. Collaboration between radiologist and urologist
- became much better and progression of disease could be precisely established.
- The method is very attractive as it is a non-invasive one.
