Sequence Views
Different views are commonly used in hand MRI scans to provide images showing different details of the anatomy of the hand.
The sagittal view is the view from the side of the hand.
The coronal view is the view from the top of the hand.
The axial view is the view from the finger tips towards the wrist.
Different Image Types
Different image types are used to highlight different elements within the body.
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 Hand studies, T1 weighted images are typically performed in coronal views.
T2 Weighted images can be identified as ‘water based images’. These are used to emphasise water in tissues such as inflammation which is common in many pathology and injury processes.
In hand Studies, T2 weighted images are typically performed in sagittal views.
Proton Density sequences are generally used to emphasise the anatomical detail of the body part being scanned.
In hand studies, the Proton Density sequence is typically performed in an axial view
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 Hand studies, the STIR sequence is typically performed in coronal and sagittal views.
The X-Bone sequence is specific to Esaote brand MRI scanners, as used at Bayside Standing MRI. It is a combination of T1 weighted, T2 weighted, Proton Density and STIR images. It is therefore a mix of all 2d sequences which can be used to better highlight certain types of problems than individually performed sequences.
In wrist studies, the X-Bone sequence is typically performed using an axial view.
