[Regularities of the computer-tomographic and macro-microscopical anatomy and topography of the retroperitoneal space
Abstract:
Variant-, age- and sex-related peculiarities of the intravital anatomy and topography of the retroperitoneal space (RS) fasciae, fatty tissue layers, structures and organs were studied on autopsy material (organ complexes of 50 men and women aged 22-71 years) and on clinical material (computer tomographs of 140 men and women aged 20-75 years). Te quantitative analysis has shown that the height of the RS was equal to 198 +/- 26 mm, its cross sectional area--to 35 +/- 5 mm2, and total RS volume--to 1254+/- 169 cm3. Current classifications of RS regions and parts as well as RS fatty tissue layers, are presented. The latter distinguishes five fatty tissue layers: retroperitoneal, parasuprarenal, pararenal, paraureteral, paracolonic, and retropancreatic.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
