The diagnostic value of 3D-TOF-MRA in combination with 3D-FIESTA-C in preoperative evaluation of vascular compressive trigeminal neuralgia / 实用放射学杂志

Objective To investigate the diagnostic value of three-dimensional time-of-flight magnetic resonance angiography(3D-TOF-MRA)in combination with three-dimensional fast imaging employing steady-state acquisition with phase cycling (3D-FIESTA-C),using multiplanar reconstruction and image fusion technology in preoperative evaluation of vascular compressive trigeminal neuralgia (TN) and to improve the diagnostic accuracy.Methods 3D-TOF-MRA and 3D-FIESTA-C images using MPR and image fusion technology of 70 patients with TN confirmed by surgery were reviewed retrospectively,and compared with intraoperative findings separately and together.Results Microvascular decompression (MVD)surgery was performed in all 70 patients.Compared with surgical results, 3D-TOF-MRA showed presence of the offending vessel around the cisternal segment of trigeminal nerve in 55 cases with a positive rate of 79%.3D-FIESTA-C showed the presence of the offending vessel in 60 cases with a positive rate of 85%.65 cases were found when combining both 3D-TOF-MRA and 3D-FIESTA-C images,with a positive rate of 93%.No positive imaging findings were seen in 5 cases.Operation showed that offending vessels were small arteries in 3 cases and were petrosal veins in 2 cases.The main offending vessels were superior cerebellar artery and basilar artery.Conclusion Combining images of 3D-TOF-MRA and 3D-FIESTA-C using MPR and image fusion technology can show the relationship between offending vessels and the trigeminal nerve clearly in patients,and provide guidance for MVD surgery.There are still some deficiencies in the display of venules,and other sequences of MRI (such as CE-3D-FIESTA sequences)may be helpful.

Clinical Research of Chinese Medicine Inunction Wet Dressing Therapy and Helium Neon Laser in the Treatment of Rheumatoid Arthritis / 中国药房

OBJECTIVE:To observe the clinical efficacy of Chinese medicine inunction wet dressing therapy and helium neon laser in the treatment of rheumatoid arthritis.METHODS:Both groups received Methotrexate tablets,Salazosulfapyridine tablets,Loxoprofen tablets.Observation group were additionally treated with Chinese medicine inunction wet dressing therapy and helium neon laser with a treatment course of 30 days.RESULTS:The effective rate was 70.00% for control group and 93.55% for observation group,there was significant difference between two groups(P
