SECTION: Anatomy of the thorax, abdomen, and pelvis

Images and anatomical references

We have created an anatomical atlas of abdominal and pelvic CT which is an interactive tool for studying the conventional anatomy of the normal structures based on a multidetector computed tomography. Anatomical structures of the abdomen and pelvis are visible as interactive labelled images.

 

Cross sectional anatomy: MDCT of the abdomen and pelvis

 

An enhanced (portal venous phase – 70 seconds) multidetector computed tomography was performed on a healthy subject in axial plane with coronal and sagittal reformatted images.
Data and DICOM images stocked on our PACS (Picture Archiving and Communicating System) were processed and exported as JPEG images.  Adobe Flash and Adobe Photoshop allowed us to develop an atlas-based application with suitable functionality and user interface for the study of the abdomen and pelvis anatomy (labelled according to the Terminologia Anatomica).

Anatomy of the abdominal cavity and the male pelvis: how to visualize anatomic labels

 

This tool provides access to a CT atlas in the axial plane, allowing the user to interactively learn abdominal anatomy. Images are labelled, providing an invaluable medical tool. The test mode allows instant evaluation of user progress.
The horizontal menu gives access to the groups of anatomical labels:

 

  • Organs: liver, spleen, suprarenal gland, pancreas, gallbladder,
  • Digestive tract: oesophagus, stomach, pyloric antrum, duodenum, jejunum, ileum, colon (caecum, ascending, transverse, descending colon, right and left colic flexure, sigmoid), rectum
  • Urinary system: kidney (renal cortex and sinus), ureter, urinary bladder, prostate, urethra
  • Arteries: abdominal aorta, iliac arteries, mesenteric arteries (inferior and superior), renal, splenic, heptatic, gastroduondenal, cystic arteries
  • Veins: gonadic (testicular), iliac, epigastric, pudendal, gluteal, renal, hemiazygos veins, inferior vena cava
  • Portal system: mesenteric (inferior and superior), splenic, hepatic portal veins
  • Muscles, fascia, diaphragm
  • Bones: ilium, sacrum, ribs
  • Nerves
  • Peritoneal cavity and spaces
  • Lymph nodes regions

As the cursor is moved over a particular anatomic area of the liver, that liver segment is highlighted and labelled: this tool has been chosen to show hepatic segmentation:

 

  • Segment 1 : posterior segment – caudate lobe
  • Segment 2 : left posterior lateral segment
  • Segment 3 : left anterior lateral segment
  • Segment 4 : left medial segment
  • Segment 5 : anterior medial segment
  • Segment 6 : anterior lateral segment
  • Segment 7 : posterior lateral segment
  • Segment 8 : posterior medial segment

The vertical left menu provides coronal and sagittal reformatted images of the abdomen and pelvis, with digestive medical illustration based on a three dimensional (3D) model (volume rendering of the CT).
This module is a comprehensive and affordable learning tool for radiology and medical students and residents and especially for radiologist, surgeons and gastrologists.
