    Summary

    Zonography in urography improves visualization of the renal system using fewer exposures. This method significantly reduces gonad radiation dose compared to standard techniques.

    Area of Science:

    • Radiology
    • Medical Imaging

    Background:

    • Conventional urography utilizes ordinary films and tomograms, often requiring multiple exposures.
    • This can lead to a higher radiation dose, particularly to the gonads.

    Purpose of the Study:

    • To evaluate the efficacy of zonography in urography for visualizing the renal system.
    • To assess the potential for reducing radiation exposure to patients.

    Main Methods:

    • Implementing zonography as an alternative to standard films and tomograms in urography.
    • Analyzing the number of exposures required for adequate visualization of the caliceal system and renal contours.

    Main Results:

    • Zonography allows visualization of the caliceal system and renal contours with only 1-2 exposures.
    • The total number of exposures is limited to 3-4, significantly reducing patient radiation dose.

    Conclusions:

    • Zonography is an effective technique for improving visualization in urography.
    • This method markedly reduces gonad radiation dose, offering a safer alternative for patients.
