Cross sectional and imaging anatomy of the thorax

This video deals with the anatomy of the thorax in transverse anatomical and axial CT sections. The video begins with a transverse anatomical section at the root of the neck and continues down to the level of the T10 vertebra where the esophagus passes through the diaphragm.

The anatomical sections are arranged to match CT & MRI sections to provide a better understanding of the imaging anatomy of the thorax. The arrangement of thoracic structures is followed in (16) serial transverse sections of the thorax and compared with (10) representative axial CT sections at different levels.

The anatomical sections are selected from the Visible Human Project. For more information about this project refer to: http://www.nlm.nih.gov/research/visib...

A plastic model is used where necessary to explain the 3-D relations necessary to understand the 2-D sections.

After completion of this video session, it is expected that you will be able to identify the anatomical features expected to be seen at vertebral levels T2, 4, 8, and 10. The following structures are identified and followed in transverse anatomical sections or CT axial sections:

Vessels:
Ascending aorta, descending aorta, arch of aorta, brachiocephalic trunk, left common carotid artery, left subclavian artery, right coronary artery, internal thoracic (mammary) artery, superior vena cava (SVC), inferior vena cava (IVC), azygos vein, right and left brachiocephalic trunks, internal jugular vein, subclavian vein, coronary sinus, pulmonary trunk, right and left pulmonary artery, pulmonary vein.

Viscera:
Esophagus, lungs, liver, spleen, thymus, stomach, heart: right ventricle, left ventricle, right atrium, right auricle, left atrium, vestibule, infundibulum, apex, interventricular septum, trabeculae carneae, papillary muscle, moderator band, right atrioventricular orifice, trachea, right and left main bronchus, right upper lobe bronchus, hilar lymph node, carinal lymph nodes, right and left domes of the diaphragm.

Musculoskeletal structure:
Ribs, costal cartilages, sternum, scapula, clavicle, sternoclavicular joint, intercostal muscles, serratus anterior, pectoralis major, pectoralis minor, vertebral body, transverse process, spinous process, vertebral canal, spinal cord, costovertebral joint, costotransverse joint, intervertebral disc.
