目的:分析螺旋CT增强延迟5min后扫描针对颅内小结核瘤诊断中的应用价值,为临床早期诊断提供科学依据。方法:选取2011年4月—2013年4月我院收治的34例患有结核性脑膜炎疑颅内小结核瘤患者的临床资料,总结和分析后行螺旋CT增强扫描后延迟5min后再行螺旋CT平描,从而对患者的病情进行更好的诊断。结果:经过螺旋CT增强后延迟5min再扫描后发现,28例呈阳性,其中呈阳性9例又行MRI的检查,与CT结果相符。结论:采用螺旋CT增强后延迟5min再扫描方法诊断早期颅脑小结核瘤切实可靠。主要是增强延迟等到血管期过后才能看到平扫及常规螺旋CT增强扫描不易检出的早期小的结核瘤。相比于MRI检查更为经济实用,适合于牧业地区及磁共振尚未普及地区。
OBJECTIVE: To analyze the value of spiral CT in the diagnosis of intracranial tuberculoma after delayed 5 min, and provide a scientific basis for early clinical diagnosis. Methods: The clinical data of 34 patients with tuberculous meningitis with intranasal small tuberculous meningioma admitted to our hospital from April 2011 to April 2013 were selected. The data of delayed spiral CT scan after 5 min were retrospectively analyzed. Spiral CT plain scan, in order to better diagnose the patient’s condition. Results: After 5 min re-scan after enhancement with spiral CT, 28 cases were positive, of which 9 cases were positive and MRI examination was performed, which was consistent with CT findings. Conclusion: It is practicable to diagnose early stage tuberculous tuberculoma with 5 min re-scanning by enhanced spiral CT. Mainly to enhance the delay until after the vascular period can see the plain scan and conventional spiral CT enhanced scan is not easy to detect early small tuberculomas. Compared with MRI examination more economical and practical, suitable for animal husbandry areas and magnetic resonance has not yet popularized areas.
