Offering the unique benefit of a combined urologic and radiologic approach, this book defines the appropriate clinical investigation to be carried out in evaluating a wide range of urologic disorders. From demonstrations of ultrasound, CT scanning, magnetic resonance imaging, color flow Doppler, position emission tomography, and radioimmunodetection, to the dramatic implications of new laboratory technology such as prostrate-specific antigen and evolving molecular techniques, to the replacement of older, invasive techniques with more accurate and less invasive ones, the book provides a wealth of clinical diagnostic guidelines.
