RESUMEN
Objective To explore the application value of multimodal MRI in the preoperative staging of cervical cancer.Methods The preoperative imaging data of 60 patients with cervical cancer confirmed by surgical pathology or biopsy were analyzed retro-spectively.The results of preoperative staging by multimodal MRI and postoperative pathological staging were compared.The diag-nostic accuracy of multimodal MRI in staging of cervical cancer was evaluated.Results Among the 60 cases,the preoperative staging results of multimodal MRI were 25 ⅠB,20 ⅡA1,9 ⅡA2,and 6 ⅢC.While the postoperative pathological staging results were 27 Ⅰ B,18 ⅡA1,9 ⅡA2,and 6 ⅢC.The staging results achieved by preoperative multimodal MRI and postoperative pathological staging were in good agreement.With the postoperative pathological staging as the gold standard,the diagnostic accuracy of multimodal MRI in preoperative staging was 100.00%(25/25),85.00%(17/20),77.78%(7/9),and 83.33%(5/6),respectively.Conclusion Multimodal MRI has a high accuracy in the preoperative staging of cervical cancer which can be used as a routine evaluation tool for the accurate preoperative staging of cervical cancer in clinical work.
RESUMEN
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.
