3T MRI vies with arthroscopy for detection of wrist ligament tears
ثبت نشده
چکیده
Thirty-five of the 49 patients also underwent fluoroscopy-guided 3T MR arthrography of the wrist joint using a gadolinium/saline contrast mix. Arthroscopy found TFCC tears in 22 patients, scapholunate tears in 18, and lunatotriquetral tears in 11. Nineteen TFCC tears, 16 scapholunate tears, and nine lunatotriquetral tears were seen on 3T MRI. There were no false-positive readings on MRI compared with arthroscopy. MR's sensitivity for detection of TFCC, scapholunate, and lunatotriquetral tears was, respectively, 86%, 89%, and 82%. MR's specificity for detection of all tears was 100%.

Accuracy of MRI in Comparison with Arthroscopic Findings in the Diagnosis of Anterior Cruciate Ligament and Meniscus Tears
Background: Magnetic resonance imaging (MRI) is of great aid in the diagnosis of knee lesions. Nevertheless, arthroscopy has remained the reference standard for the diagnosis of internal derangements of the knee, against which alternative diagnostic modalities should be compared. This study was designed to assess the value of MRI and clinical examination in the diagnosis of Anterior Cruciate Li...
متن کاملWrist Imaging: Ligaments and Triangular Fibrocartilage
Magnetic resonance imaging (MRI) and MR arthrography are both effective means to evaluate the instrinsic and extrinsic ligaments of the wrist, as well as the triangular fibrocartilage (TFC) [1-6]. High resolution detail of the wrist can be achieved with a variety of magnet strengths, with 1.5 Tesla (T) and 3T being the most commonly utilized in current practice. Dedicated wrist coils are critic...
متن کاملWrist MRI Arthrogram v Wrist Arthroscopy: What are we Finding?
The aim of the study was to compare the radiological findings of wrist arthrogram with wrist arthroscopy. This allowed us to establish the accuracy (sensitivity, specificity) of MRI arthrogram as a diagnostic tool. Thirty patients (20 female and 10 male) have undergone both wrist MRI arthrogram and wrist arthroscopy over the last 3 years at a District General Hospital. The mean age at arthrogra...

OBJECTIVE To evaluate the prevalence of deltoid ligament and distal tibiofibular syndesmosis injury on 3T magnetic resonance imaging (MRI) in patients with chronic lateral ankle instability (CLAI). MATERIALS AND METHODS Fifty patients (mean age, 35 years) who had undergone preoperative 3T MRI and surgical treatment for CLAI were enrolled. The prevalence of deltoid ligament and syndesmosis inj...

OBJECTIVE To compare the diagnostic performance of the three-dimensional turbo spin-echo (3D TSE) magnetic resonance imaging (MRI) technique with the performance of the standard two-dimensional turbo spin-echo (2D TSE) protocol at 1.5 T, in the detection of meniscal and ligament tears. MATERIALS AND METHODS Thirty-eight patients were imaged twice, first with a standard multiplanar 2D TSE MR t...
