Atlas Of Renal Ultrasonography PDF Download

Renal sonography forms a basic part of routine diagnostic strategy. The only ambition of this small textbook is to serve as a guide for beginners in the technique, whether they are imagers or mere consumers of information. That is why we shall emphasize practical advice and diagnostic pitfalls; it is also why we shall often deal with the relations of sonography with other diagnostic procedures, which it may com plement or replace, precede or follow, the purpose being to achieve efficiency at low cost. We shall limit our subject matter to the kidney itself and the neigh boring retroperitoneal compartments, dealing only briefly with the lower urinary tract, in the study of which ultrasonic diagnosis is less well integrated and less precisely codified. We devoted considerable space to renal sonography in our book Clinical Atlas of Ultrasonic Radiography, published in 1973. Since then, nothing has changed and everything has changed. Nothing, because even then the differential' diagnosis between a solid and a cystic mass, the etiologic diagnosis of a nonsecreting kidney, and the positive diagnosis of a traumatic juxtarenal hematoma were quite reliable, making possible drastic reductions in the indications for instrumental roentgenologic examinations. Everything, because improved resolution and grey scale imaging (already partially achieved in 1973, thanks to real time) have profoundly refined both anatomic and pathologic ultra sonic studies. And now high resolution real time imaging is about to revolutionize renal examination techniques.
