Imaging Techniques of the Urinary Tract
摘要
The field of uroradiology has evolved significantly since the discovery of X-rays by Wilhelm Conrad Roentgen in 1895. Initially used for detecting urinary tract stones, X-rays paved the way for innovative techniques like retrograde pyelography (RGP) and intravenous urography (IVU). While IVU and angiography once dominated the landscape, the emergence of ultrasound, CT scans, and MRI has led to a shift in diagnostic preferences. Ultrasound, evolving from static images to real-time dynamic visuals, has become a cornerstone in diagnosing urinary tract conditions, aided by innovations like Doppler ultrasound. CT scans, utilizing X-rays and computer algorithms, offer detailed cross-sectional images, albeit raising concerns about radiation exposure. Meanwhile, MRI, harnessing magnetic properties without radiation, has advanced to become a pivotal tool in local staging for conditions like prostate cancer. As technology continues to progress, these imaging modalities redefine uroradiology, providing comprehensive diagnostic insights while balancing safety and precision.
