Sequence Views

Different views are commonly used in knee MRI scans to provide images showing different details of the anatomy of the knee. Sagittal

The sagittal view is the view from the side of the knee.

Axial

The axial view is the view of the knee from the upper leg, looking down towards the lower leg.

Coronal

The coronal view is the view from the front or back of the knee.

Different Image Types

Different image types are used to highlight different elements within the body. T1 Weighted

T1 weighted images can be identified as ‘fat based images’, as they emphasise body fat in tissues. They are also used to highlight anatomical detail.

In knee studies, T1 weighted images are typically performed in axial views.

STIR

STIR images are generally used to highlight water in the body to aid in identifying inflammation, bruising and fractures. These images are not used to highlight anatomical detail.

In knee studies the STIR sequence is typically performed in coronal and sagittal views.

Proton Density

Proton Density sequences are generally used to emphasise the anatomical detail of the body part being scanned.

In knee studies, the Proton Density sequence is typically performed in coronal and sagittal views.
