intraarticular variants of the long head of the biceps tendon

MR

arthrography: correlation between anatomic intraarticular variants of the long head of the biceps tendon (long head biceps tendon) and superior labral anterior to posterior (SLAP) lesions. a MR arthrography, sagittal SE T1-weighted. In MESO-PA anatomical variant, long head biceps tendon is partially fused to the inferior surface of the supraspinatus tendon (arrow). Contrast agent outlines acute angle between the anterior portion of the long head biceps tendon and the inferior surface of the supraspinatus (curved arrow). b Same patients as in a. MR arthrography, coronal SE T1-weighted. MESO-PA anatomical variant is associated with SLAP lesion type I. MESO-PA anatomical variant is associated with SLAP lesion type I (arrow)

MR

arthrography: correlation between anatomic intraarticular variants of the long head of the biceps tendon (long head biceps tendon) and superior labral anterior to posterior (SLAP) lesions. a MR arthrography, sagittal SE T1-weighted. In ADH-PM anatomical variant, long head biceps tendon is partially medially to the inferior surface of the supraspinatus (arrow). b Same patients as in a. MR arthrography, coronal SE T1-weighted. ADH-PM anatomical variant is associated with SLAP lesion type II (arrow)

MR

arthrography: correlation between anatomic intraarticular variants of the long head of the biceps tendon (long head biceps tendon) and superior labral anterior to posterior (SLAP) lesions. a MR arthrography, T1-weighted with fat signal saturation (FAT-SAT) imaging on axial plane. SPL-DO anatomical variant (long head biceps tendon has double band) comes from supraspinatus tendon (white curved arrow) and from glenoid (white arrow). b MR arthrography, sagittal SE T1-weighted. SPL-DO anatomical variant (double beams of long head biceps tendon; black arrows). c MR-arthrography, coronal SE T1-weighted. SPL-DO anatomical variant is associated with SLAP lesion type IV (white arrow)
