Methods and Materials
We retrospectively reviewed and analyzed arthro-MRI exams of 23 patients (20 males and 3 females) who underwent arthro-MRI exam with a 1.5 Tesla unit and arthroscopy within successive 7-45 days.
All patients were athletes with clinically suspected of biceps pulley damage; they were positive to Palm-up,
O’Brien and Hawkins tests.
On MRI,
the shoulder was studied with dedicated coil with the arm in neutral position,
in internal and external rotation.
ABER position was used in 2 patients.
Intra-articular injection of 13-18 cc of contrast agent (Gd-DOTA) was made under fluoroscopic guide.
Arthro-MRI protocol included proton density-weighted (PD-w) sequences with and without fat suppression acquired in oblique-sagittal,
oblique-coronal and axial planes.
MR parameters included: FOV = 16-18 cm,
matrix = 256x256 and number of excitations = 2.
TE and TR were respectively of 13.5 ms and 1800 ms and slice thickness was 4.0 mm with intersection gap of 0.4 mm.
