[The labrum glenoidale]. [峡谷唇]。

{"title":"[The labrum glenoidale].","authors":"J Bernageau","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>The value of assessment of the labrum glenoidale has increased with the development of CT arthrography and arthroscopy. Assessment of the labrum glenoidale must be preceded by standard radiological assessment looking for of a lesion of the glenoidal margin. CT arthrography is currently the most reliable technique due to the definition and fine sections which can be obtained. Morphological variations of the labrum glenoidale and glenohumeral ligaments are the main causes of diagnostic errors. MRI also provides AP sections, but is less effective. MR arthrography is more effective and may constitute the technique of the future, but it requires intra-articular puncture and is expensive. Schematically, there are four sites of lesion of the labrum glenoidale: anteroinferior secondary to anterior instability, posterior secondary to posterior instability, Snyder's SLAP lesions and the anterosuperior lesions described by Andrews and Carson. The demonstration and interpretation of SLAP lesions is difficult, particularly types I and II. Analysis of the labrum glenoidale is limited. It is essentially indicated in unstable and painful shoulders, possibly secondary to a missed instability accident when the antero-inferior glenoidal margin is normal or doubtful. However, when looking for a lesion of the labrum glenoidale, it is logical to perform CT arthrography rather than arthroscopy, which is far more invasive and expensive.</p>","PeriodicalId":75506,"journal":{"name":"Annales de radiologie","volume":"38 5","pages":"266-74"},"PeriodicalIF":0.0,"publicationDate":"1995-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19758501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This technique now competes with color Doppler flow sonography and spiral CT. MR angiography of the renal arteries can be performed with 2D or 3D, flight-time or phase contrast sequences. Main and co-dominant arteries are usual by visualized on all sequences, but small accessory arteries are often missed. The diagnosis of stenosis is based on the presence of an area of signal extinction. The degree of extinction depends on the degree of turbulence, the type of technique, the length of TE and spatial resolution parameters, which is why scoring of stenoses is difficult and frequently overestimated. The diagnostic performance for stenosis is between 50 and 100% for sensitivity and between 80 and 97% for specificity. Detection of distal stenoses is poor because of respiratory artifacts. Multiphase acquisitions make it possible to measure the renal blood flow on each renal artery, adding hemodynamic criteria to this diagnosis.</p>","PeriodicalId":75506,"journal":{"name":"Annales de radiologie","volume":"38 1-2","pages":"69-78"},"PeriodicalIF":0.0,"publicationDate":"1995-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18636165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
