Objective To probe into the anatomy and clinical application of the facial nerve canal surface by multislice spiral CT image curved planar reformation. Methods Fifty patients with facial nerve disease were selected as study group from January to November in 2010, 50 healthy subjects were selected as control group, using models of multislice spiral CT scan for the patient, scanning from the upper edge of the orbital under external auditory canal edge of the connection as a horizontal line, ranging from the lower edge of mastoid process to the petrous bone on the edge of the data obtained in the Wizard workstation reconstruction. All the measurements were more than two measurements of the average physician. Results Normal facial nerve canal in control group could be displayed clearly in an image, display rate was 100.00%(50/50), and the segment data could be accurately measured; axial reconstruction, reconstruction of coronal and sagittal reconstruction of the three comparison of measured direction, fan sections, horizontal and vertical segments of the length and diameter were not significantly different (P＞0.05), and the first and second bending angle of bending angle was no significant difference (P ＞ 0.05 ). Compared with control group, the patients with vascular disease in study group showed significantly decreased rate, the difference was significant (P ＜ 0.05). Conclusion Curved planar reformation of multislice spiral CT diagnosis of facial nerve canal disease has great clinical significance, should be widely applied.

Objective To explore the value of real time contrast-enhanced ultrasound (CEUS) in differential diagnosis of benign and malignant adrenal lesions.Methods Totally,57 adrenal lesions (26malignant and 31 benign) underwent conventional ultrasound and real-time CEUS.The enhancement patterns including types of time-intensity curve,centripetal fill-in,homogeneity and intensity of enhancement were analyzed.Results The enhancement pattern of normal adrenal gland was homogeneous,centrifugal and rapid perfusion from the medulla to the cortex.Four enhancement patterns were significantly different between benign and malignant adrenal lesions (P ＜0.05).If enhancement in the early arterial phase and rapid washout was suggestive of malignancy,the sensitivity and specificity of CEUS were 96.2％ and 77.4％,respectively.If peripheral to central filling was suggestive of malignancy,the sensitivity and specificity of CEUS were 76.9 ％ and 80.7 ％,respectively.Conclusions The patterns of real-time CEUS are helpful in differential diagnosis of malignant and benign adrenal lesions.
