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...
Our aim was to determine the clinical value of MRI and CT arthrography in predicting the presence of loose bodies in the elbow. A series of 26 patients with mechanical symptoms in the elbow had plain radiography, MRI and CT arthrography, followed by routine arthroscopy of the elbow. The location and number of loose bodies determined by MRI and CT arthrography were recorded. Pre-operative plain ...
Does Immobilization Post Injection Reduce Contrast Extravasation in MR Arthrography of the Shoulder?
Introduction Using both iodinated X-ray contrast and gadolinium (Gd) based MR contrast agents is helpful when performing MR arthrography. Joint visualization is enhanced if fluoroscopy is used for needle placement and a CT exam can be performed without an additional needle stick if the MR arthrogram is unsuccessful. However, the presence of iodinated contrast alters the relaxivity of gadolinium...
CT arthrography and arthroscopy were used to assess tears of the rotator cuff in 259 shoulders. Tear size was determined in the frontal and sagittal planes according to the classification of the French Arthroscopy Society. CT arthrography had a sensitivity of 99% and a specificity of 100% for the diagnosis of tears of supraspinatus. For infraspinatus these figures were 97.44% and 99.52%, respec...
