“…Patients underwent imaging with the arm in neutral position. T1-weighted spin-echo images (TR range/ TE range, 500-700/ [14][15][16][17][18][19][20] were obtained in the transverse plane, sagittal oblique plane (parallel to the glenohumeral joint), and coronal oblique plane (perpendicular to the glenohumeral joint space). T2-weighted fast spin-echo (FSE) images (3,000-4,200/90-120) were obtained in the coronal oblique plane.…”

“…In previous studies, direct MR arthrography showed significantly higher sensitivity in the detection of partial-thickness tears compared with conventional MR imaging and US techniques [8,15]. Since results on the performance of direct MR arthrography in the diagnosis of partial-thickness tendon tears were predominantly obtained in small series, further investigations are required to verify and analyze limitations of this imaging modality [8,[15][16][17]. The purpose of our study was to assess the diagnostic performance of MR arthrography in the diagnosis of articular-sided partial-thickness and full-thickness rotator cuff tears in a large symptomatic population.…”

Rotator cuff tears: assessment with MR arthrography in 275 patients with arthroscopic correlation

et al. 2006

We assessed the diagnostic performance of magnetic resonance (MR) arthrography in the diagnosis of articular-sided partial-thickness and full-thickness rotator cuff tears in a large symptomatic population. MR arthrograms obtained in 275 patients including a study group of 139 patients with rotator cuff tears proved by arthroscopy and a control group of 136 patients with arthroscopically intact rotator cuff tendons were reviewed in random order. MR imaging was performed on a 1.0 T system (Magnetom Expert, Siemens). MR arthrograms were analyzed by two radiologists in consensus for articular-sided partial-thickness and full-thickness tears of the supraspinatus, infraspinatus, and subscapularis tendons. At arthroscopy, 197 rotator cuff tears were diagnosed, including 105 partial-thickness (93 supraspinatus, nine infraspinatus, three subscapularis) and 92 full-thickness (43 supraspinatus, 20 infraspinatus, 29 subscapularis) tendon tears. For full-thickness tears, sensitivity, specificity, and accuracy were 96%, 99%, and 98%, respectively, and for partial tears 80%, 97%, and 95%, respectively. False negative and positive assessments in the diagnosis of articular-sided partial-thickness tears were predominantly [78% (35/45)] observed with small articular-sided (Ellman grade1) tendon tears. MR arthrography is highly accurate in the diagnosis of full-thickness rotator cuff tears and is accurate in the diagnosis of articular-sided partial-thickness tears. Limitations in the diagnosis of partial-thickness tears are mainly restricted to small articular-sided tears (Ellman grade 1) due to difficulties in differentiation between fiber tearing, tendinitis, synovitic changes, and superficial fraying at tendon margins.

“…6 Previous studies have demonstrated MR arthrography to have higher accuracy in the detection of labral tears than conventional MR examination. [7][8][9] Based on the above findings, some researchers have advocated that MR arthrography be performed on all patients undergoing shoulder MRI. 10 However, some patients may be hesitant to undergo an invasive examination.…”

Objective: MR arthrogram imaging of the shoulder is considered more accurate in assessing shoulder pathology than conventional MRI. Arthrography is a minimally invasive procedure. However, most patients prefer to have conventional MRI rather than MR arthrogram imaging. We report the benefit of assessing pre-arthrogram conventional MRI, to determine whether an MR arthrogram is needed for further evaluation. Methods: 100 consecutive conventional shoulder MR and MR arthrography examinations performed on the same patients were reviewed retrospectively by independent reading of 2 musculoskeletal radiologists. Both conventional MR and MR arthrogram examinations were performed on each patient on the same day. Conventional MR and MR arthrogram examinations were assessed for labral tears and supraspinatus tendon tears. All patients went on to arthroscopy. Results: Of these 100 patients, 43 patients had superior labral anterior to posterior (SLAP) tears, 28 patients had posterior labral tears, 23 patients had anterior labral tears and 47 patients had full-thickness supraspinatus tendon tears on conventional MR examination reading by Reader 1. There were 42 SLAP tears, 26 posterior labral tears, 24 anterior labral tears and 47 full-thickness supraspinatus tendon tears on conventional MR examination read by Reader 2. On MR arthrogram examination, 51 patients had SLAP tears, 33 patients had posterior labral tears, 29 patients had anterior labral tears and 49 patients had full-thickness supraspinatus tendon tears on reading by Reader 1. On MR arthrogram examination, 50 patients had SLAP tears, 31 patients had posterior labral tears, 30 patients had anterior labral tears and 49 patients had full-thickness supraspinatus tendon tears read by Reader 2. MR arthrogram detected eight SLAP tears, five posterior labral tears, six anterior labral tears and two supraspinatus tendon tears not detected on conventional MR examination read by Reader 1. MR arthrogram detected eight SLAP tears, five posterior labral tears, six anterior labral tears and two supraspinatus tendon tears not detected on conventional MR examination read by Reader 2. 18 of the 21 patients with additional finding on MR arthrogram examination had normal appearing conventional MR examinations. 1 A previous study demonstrated 98% sensitivity and 96% specificity for MRI detection of full-thickness rotator cuff tears, as compared with arthroscopy.2 High sensitivity and specificity for the detection of labral tears as compared with arthroscopy with 3-T MRI has been reported.3 High sensitivity and specificity for the detection of labral tears at 1.5 T has also been reported.

“…The standardly used MR technique after gadolinium contrast injection into the shoulder joint includes spin echo T1-weighted sequences with fat saturation (T1-FS) applied in different planes, and the total examination lasts at least 10-15 min to perform [1][2][3][4][5][6][7].…”

Fast MR arthrography using VIBE sequences to evaluate the rotator cuff

Purpose The purpose of this paper was to evaluate if short volumetric interpolated breath-hold examination (VIBE) sequences can be used as a substitute for T1-weighted with fat saturation (T1-FS) sequences when performing magnetic resonance (MR) arthrography to diagnose rotator cuff tears. Materials and methods Eighty-two patients underwent direct MR arthrography of the shoulder joint using VIBE (acquisition time of 13 s) and T1-FS (acquisition time of 5 min) sequences in the axial and paracoronal plane on a 1.0-T MR unit. Two radiologists scored rotator cuff tendons on VIBE and T1-FS images separately as normal, small/ large partial thickness and full thickness tears with or without geyser sign. T1-FS sequences were considered the gold standard. Surgical correlation was available in a small sample. Results Sensitivity, specificity, and positive and negative predictive values of VIBE were greater than 92% for large articular-sided partial thickness and full thickness tears. For detecting fraying and articular-sided small partial thickness tears, these parameters were 55%, 94%, 94%, and 57%, respectively. The simple kappa value was 0.76, and the weighted kappa value was 0.86 for agreement between T1-FS and VIBE scores. All large partial and full thickness tears at surgery were correctly diagnosed using VIBE or T1-FS MR images. Conclusion Fast MR arthrography of the shoulder joint using VIBE sequences showed good concordance with the classically used T1-FS sequences for the appearance of the rotator cuff, in particular for large articular-sided partial thickness tears and for full thickness tears. Due to its very short acquisition time, VIBE may be especially useful when performing MR arthrography in claustrophobic patients or patients with a painful shoulder.
