  • The Characteristics and Diagnostic Values of MRI for Multiple Sclerosis

    ObjectiveTo investigate the morphology of brain regions undergoing multiple sclerosis (MS) MRI, and furthermore, to investigate possible diagnostic values of MRI for MS. MethodsMRI images of 42 MS patients (34 females and 8 males, aged between 35 and 81 years old, averaging at 58) who visited the hospital during the time from December 2007 to December 2013 were collected and analyzed. Routine T1, T2 and fluid attenuated inversion recovery (FLAIR) scans were performed on all the 42 patients. Sagittal T1, T2 and FLAIR scans were performed when necessary. Contrast-enhanced MRI was performed on 9 of the 42 patients. The abnormal findings from MRI scans of all the 42 patients were analyzed. The analysis was further concluded to yield general characteristics of MS patients under MRI. ResultsA total of 286 lesions were identified in 42 patients. Ninety (31.6%) of the 286 lesions (seen in 35 patients) were found to locate around lateral ventricles; 67 (23.4%) at centrum semiovale (seen in 29 patients); 59 (20.6%) in deep white matter (seen in 28 patients); 46 (16.1%) around corpus callosum (seen in 30 patients); 21 (7.3%) in brain stem, basal ganglia and cerebellar hemispheres (seen in 9 patients); and 3 (1.0%) at cervical spinal cord. In routine MRI images, the lesions showed up as low T1 signal, high T2 signal and high FLAIR signal with the shape of ovoid or round. No mass effect was observed in lesions. In the contrast-enhanced MRI images, the 25 observed lesions showed mild enhancements with the shape of ring, semi-ring and arc. ConclusionCertain characteristic features can be observed in MS MRI images. MRI is an effective diagnostic method for multiple sclerosis diagnosis.

  • Clinical Efficacy of Recurrent Laryngeal Nerve Monitoring in Video-Assisted Thyroidectomy for Huge Thyroid Nodules

    ObjectiveTo investigate effect of recurrent laryngeal nerve monitoring in video-assisted thyroidectomy for huge thyroid nodules. MethodsThe clinical data of 158 patients with huge thyroid nodules underwent videoassisted thyroidectomy from January 2013 to June 2015 were analyzed retrospectively, the recurrent laryngeal nerves were monitored in 79 cases (monitoring of recurrent laryngeal nerve group) while the recurrent laryngeal nerves were not monitored in the other patients (non-monitoring of recurrent laryngeal nerve group). The operative time, blood loss, postoperative drainage, postoperative hospital stay, and the incidences of transient and permanent recurrent laryngeal nerve injury were observed between these two groups. ResultsThe video-assisted miniincision thyroidectomy was successfully completed in these 158 cases. Compared with the non-monitoring of recurrent laryngeal nerve group, the operative time (min) was shorter (76.2±23.4 versus 89.2±29.8, P < 0.05), the blood loss and the postoperative drainage were less (16.3±13.6 versus 20.6±10.7, P < 0.05; 20.7±9.6 versus 25.5±9.1, P < 0.05) in the monitoring of recurrent laryngeal nerve group. But the postoperative hospital stay (d) had no significant difference between the monitoring of recurrent laryngeal nerve group and the non-monitoring of recurrent laryngeal nerve group (3.2±1.3 versus 3.3±1.9, P > 0.05). Eight weeks later, the incidence of transient recurrent laryngeal nerve injury in the monitoring of recurrent laryngeal nerve group was significantly lower than that in the non-monitoring of recurrent laryngeal nerve group [5.6% (5/90) versus 21.8% (17/78), P < 0.05], while the incidence of permanent nerve injury had no statistical difference between the monitoring of recurrent laryngeal nerve group and the non-monitoring of recurrent laryngeal nerve group [0(0/90) versus 1.3% (1/78), P > 0.05]. ConclusionRecurrent laryngeal nerve monitoring under video-assisted thyroidectomy for huge thyroid nodules could effectively reduce incidence of nerve injury and shorten operation time.
