Images and anatomical references

This e-Anatomy module is dedicated to the radiological anatomy of the coronary arteries in coronary angiography.

 

Coronary angiography : Coronary arteries - Anatomy

Coronary angiography : Coronary arteries - Anatomy

 

 

It allows you to view a catheterisation of the left and right coronary arteries as well as a ventriculography, using radiological impacts used in current practice in the coronary angiography room.
This module is intended for students of medicine and paramedical studies to understand the impacts on coronary angiography and to recognise the different coronary arteries and their collaterals.

 

Coronary-angiographic images:

 

 

Over 500 dynamic images of an angiogram of the coronary arteries are presented here, with the incidences used in clinical practice. Small pictures at the bottom of the module serve as benchmarks for understanding the position and angle of the arch (3D images of the patient and coronary arteries):

Anatomical structures of the heart captioned in coronary angiography and ventriculography

 

Over 100 anatomical structures were captioned in this normal coronary angiogram:

  • Coronary arteries: represents the international nomenclature (Terminologia Anatomica) of right and left coronary arteries coupled with the nomenclature used in radiological practice (Cx, IVA, CT...).
  • Branches of the coronary arteries: includes the anatomical names of small branches of coronary arteries, less well visualised by coronary angiography.
  • Digital nomenclature: shows the anatomy of the coronary arteries represented by numbers (followed by their angiographic name). This nomenclature is less commonly used, but is useful for some protocols in cardiological research.
  • Heart: shows the main radiological anatomical reference points of the heart in interventional radiology in order to navigate (apex, base of the heart, pulmonary face...)
  • Other structures: details the extracardiac structures visible in this coronary angiography (lungs, diaphragm, spine, aorta).

The Details tab

 

This allows the user to choose to display all the anatomical legends on this coronary angiography or to only display the most important anatomical structures in order not to overload the images.

 

The impacts tab

 

Allows the user to navigate between the different radiological impacts in coronary angiography.

 

 

Ventriculography : Left ventricle, Aorta

Ventriculography : Left ventricle, Aorta

 

 

Language and anatomical terminology

 

We have used the Terminologia Anatomica to caption for all the anatomical structures, with translations into English, French, Japanese, German, Chinese, Portuguese, Russian, Czech and Spanish.
