The aims of this presentation are: to describe the procedure and protocol for dynamic shoulder magnetic resonance (DS-MR) imaging in the evaluation of the subacromial impingement syndrome (SIS); to characterise qualitatively and quantitatively acquired dynamic shoulder MR images; to illustrate findings of DS-MR imaging in tendinopathy,
partial-thickness and complete tears of the supraspinatus tendon.
Shoulder pain affects approximately a third of general population,
particularly older individuals .
Subacromial impingement syndrome (SIS) is the most prevalent clinical diagnosis in these patients and the syndrome is diagnosed in one-half of shoulder pain sufferers .
SIS refers to the cluster of symptoms with typical presentation of pain in the lateral part of deltoid muscle with pain intensity increasing during functional movements,
particularly during the elevation of the arm. The...
Findings and procedure details
PROCEDURE A total of eighteen patients with shoulder pain were studied.
Standard and dynamic MR images were acquired using an 0.25 T open bore MRI scanner (Esaote S.p.A,
Before entering the scanner environment,
patients were explained and rehearsed the abduction movement they needed to perform.
Prior to the dynamic MR,
the standard MR images were acquired to report to the clinician the status of visible musculoskeletal structures.
On standard shoulder MR images twelve patients...
We have illustrated the dynamic shoulder MR procedure and findings in subacromial impingement syndrome patients,
who have been diagnosed on the conventional MR images with full- or partial thickness supraspinatus tears and in patients with supraspinatus tendinopathy.
The biggest reduction of the subacromial space in baseline and during the abduction movement had patients with full-thickness supraspinatus tears.
The DS-MR imagingof patients with supraspinatus tendinopathy gives the most...
