This study unit will enable you to:
- Identify proton density (PD)-weighted MR images.
- Learn the most important structures of the knee joint and their anatomical relations.
Explore MRI scan
Different MRI sequences allows for different contrast between adjacent structures of a given body region.
One sequence that is very useful to evaluate the knee joint - and most musculoskeletal structures - is the proton density-weighted sequence, also known as PD-weighted. PD images usually show similar signal intensity on fluids and fat, that normally appear as a light gray. This helps identifying this sequence.
The images below show the main structures that can be identified in the knee MRI using PD-weighted sequences.
You can study each structure individually with the following gallery:
