Description
A series of 22 patients operated for primary hyperparathyroidism was reportect. The parathyroid adenoma was located preoperatively by MRI and ultrasonography. Measurement of the relaxation time was performed in vitro at 370 C in a 0.47 Tesla field during the 30 minutes following resection. The relaxation times obtained at a precession frequency of 20 mHz were 0.844 ± 0.16 sec for T1 and 0.082 ± 0.025 sec for T2. MRI had a sensitivity of 73% and a specificity of 88% for the localization of the parathyroid adenoma, while ultrasonography had a sensitivity of 73% and a specificity of 98%
Abstract (French)
On propose une serie de 22 patients operes pour hyperparathyroidisme primaire. L'adenome parathyroidien est localise en preoperatoire par l'IRM et l'echographie. Une mesure du temps de relaxation est realisee in vitro a 370C dans un champ de 0,47 Tesla, dans les 30 minutes suivant l'exerese. Les temps de relaxation ainsi obtenus a une frequence de precession de 20 mHz sont de 0,844 ± 0,16 s pour le T1 et de 0,082 ± 0,025 s pour le T2. Pour la localisation de l'adenome parathyroidien, la sensibilite obtenue pour l'IRM est de 73%, la specificite de 88%. Pour l'echographie, la sensibilite est de 73% et la specificite de 98%Additional details
