Abstract PURPOSE: This study was designed to evaluate the application of three-dimensional (3D) transrectal ultrasound (TRUS) in diagnostics, staging, and treatment planning of rectal cancer. METHOD: Transversal images, generated during conventional TRUS examination, are recorded by means of a specially designed computer-based system to obtain a 3D array of slices, covering the whole region of interest. Different structures (normal or pathologically affected) are segmented, isolated, and rendered using the tools of the system to produce a realistic spatial view of investigated organs. Dynamic movies are also generated and replayed for better realization of spatial interrelations of studied objects. RESULTS: Nineteen patients (18 with rectal cancer and 1 who was healthy) have been examined. In 15 patients, full 3D TRUS reconstruction was performed. Results are illustrated with several examples from the studied group. CONCLUSION: We consider 3D TRUS a useful add-on to conventional TRUS. It may significantly improve understanding of the interrelation between normal and pathologic structures and help to exact preoperative staging and treatment planning of rectal carcinoma patients.
