Learning objectives
Magnetic resonance imaging of thearmand forearm has been an area of great challenge to radiologists over the years.
This is compounded by inadequacy of reliable material available,
thus makingreporting of pathologies rather 'superficial'.
.
The purpose of this exhibit is to provide an easy yet comprehensive guide in understanding the anatomy of thearmand forearm thus expanding the scope of this investigation.
Background
Multiplanar multiechoMRimaging of the rightarmand forearm,
with and without fat suppression,
was performed on a group of 15 apparently normal individuals using a 3T Siemens Magnetom.Imageswere reviewed by two radiologists of equal work experience.
.
In our experience T1W imaging of the arm and fat supressed Proton Density imaging of the forearm are among the better imaging sequenes to elucidate normal anatomy.
.
Axial images of the arm and forearm are presented in order to ensure an adequate understanding of relations of the structures present...
Imaging findings OR Procedure Details
ANATOMY OF THE ARM:
For all practical purposes,
especially for staging neoplasms,
the arm is divided into three anatomic compartments along with the extracompartmental axillary space.
Of these compartments the humerus makes up one compartment,
while the remainder are muscular compartments,
viz.
the anterior and posterior compartments.
These muscular compartments are separated by fascial thickenings called the medial and lateral intermuscular septae,
which pass from the humerus to the brachial fascia.
.
Within the anterior compartment,
the long and short heads of the biceps brachii...
Conclusion
MRI has broadened the horizon of surgical and orthopedic interventions attributed to its inherent soft tissue contrast. Adequate knowledge of the anatomy of the arm and forearm is crucial in detailed reporting of tumors amenable for resection,
extension of infections along various planes and reporting pathologies involving major neurovascular structures.
