The Urinary System

  • Chapter
  • First Online:

Abstract

The diffusion of MDCT in veterinary practice has changed approaches to many urinary tract disorders, such as urolithiasis, renal masses, and mucosal abnormalities of the renal collecting system, ureters, and bladder. As MDCT has become more widely available, CT urography has begun to replace other imaging techniques, such as plain-film radiography and excretory urography, because it enables accurate depiction of the renal collecting systems through thinner-section imaging, more rapid scanning, improved longitudinal spatial resolution, and the consequent acquisition of high-quality reformatted multiplanar and 3D images. Moreover, qualitative and quantitative assessment of renal and excretory function is possible using dynamic CT and most advanced perfusion imaging techniques. One of the clinical applications of dual-energy (DE) CT is the spectral analysis of urinary calculi.
