This procedure is nowadays transforming cancer diagnosis although (in France at least) this facility is less accessible than CT-Scan.
The precise role of these two imaging facilities is likely to change in the near future.
There are many websites on CT-scan for medical student learning.
The Virtual Human Body project allows very interesting comparisons between CT slices and anatomical slices (made possible thanks to donations from consenting death row volunteers).
We would like to thank the authors of the radiology websites who have given their consent for the selection of a few illustrative images.
Let us list a few of them:
- Iconocerf website (Rennes France), elaborated the French College of Radiologists, with many explanations on pathologies (in French and English),
- Mc Gill University (Montréal) website , with many well documented views of thorax pathology,
- Cleveland University website, with many well documented clinical cases,
- Harvard Brigham Hospital University Radiology Unit website, with many well documented clinical cases,
- SRS Educational Resource (website from the Scottish Radiology Society)
- European Association of Radiology E-learning Initiative, with very well documented views (16,000) of various pathologies (2,000 cases),
- a specific site for gynaecologic RMI (in French) at Marseille University
- Dr Web radiologica provides a list of links to radiology websites.
As well as many other websites.
All these sites show other pathologies than cancer: a very important point of view since many other pathologies may involve images that are very similar to cancer.
Here are a few definitions of tomodensitometry planes:
![]() |
Transverse plane (or axial plane): this is a horizontal plane perpendicular to the standing human body, dividing it into upper and lower parts. This is the original reconstruction plane for tomodensitometry. Sagittal plane: a vertical plane, running from front to back, dividing the body into right and left sides. When division occurs in the middle of the body, this plane is called median plane. Frontal plane (or coronal plane):
is a vertical plane running from side to side and dividing the body into
anterior and posterior parts. |
We have collected a few characteristic views, adding to them a small diagram and comments in order to facilitate e-learning:
