Sectional anatomy is a valuable resource for understanding and interpreting imaging exams, specially computed tomography (CT) and magnetic resonance imaging (MRI). Thus, health professionals should have a solid anatomical knowledge to properly evaluate such exams during clinical assessments of cardiac, thoracic, abdominal, proctologic, gynecological and urological diseases. The chapters in this book describe the thoracic anatomy, the abdominal wall, retroperitoneal space, and the male and female pelvis. Sectional images of cadaveric material illustrate the thoracic and the abdominal cavities, kidney, ureter, prostate, penis and other male and female organs. The images and descriptions build familiarity with the anatomical traits and can be applied in the fields of urology, gynecology, proctology, radiology and surgery. This work appeals to a wide range of readers, from health professionals to residents and students of different medical specialties.
