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.
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).
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:
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:
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.
