1- Review the normal anatomy of the finger 2- Technical considerations,
including proper positioning and specific protocols based on the suspected pathology 3- Review and illustrate the various tendon pathologies
Familiarity with the anatomy of the normal finger is essential to identify pathologic entities.
MRI is a fundamental tool in the anatomic assessment,
detection and management of fingers soft-tissue traumas.
We will review this technique,
focusing on the aspects and specific protocols that can be most helpful to evaluate the suspected patologies.
Findings and procedure details
MRI PROTOCOL The patient is positioned prone with the arm raised above the head,
which places the hand close to de isocenter of the gantry.
The imaging planes for axial,
and sagittal acquisitions must be prescribed with respect to the finger rather than the hand (Fig.
1) . An adjacent finger should be included within the FOV to allow internal comparison. On MRI,
normal flexor tendons have low T1 and low T2 signal.
Flexor tendons are thicker than extensor tendons.
MRI is a very useful tool to detect finger soft tissues pathologies.
Knowing the anatomy and the MRI technical aspects is essential to diagnose them.
