目的研究对比剂动态增强磁共振成像(MRI)对垂体微腺瘤的诊断作用。方法临床拟诊的垂体微腺瘤50例行快速自旋回波对比剂动态增强扫描,接着行常规增强扫描,分析比较动态增强和常规增强两种方法对垂体微腺瘤的检出率。结果常规增强组垂体微腺瘤的检出率为72%;动态增强组垂体微腺瘤的检出率为94%。结论动态增强扫描能明显提高垂体微腺瘤的检出率。
Objective To investigate the diagnostic value of contrast-enhanced dynamic magnetic resonance imaging (MRI) for pituitary adenoma. Methods Fifty patients with pituitary microadenomas who were diagnosed clinically underwent dynamic contrast-enhanced dynamic contrast-enhanced scanning and then performed routine contrast-enhanced scanning. The detection rate of pituitary adenoma by dynamic enhancement and routine enhancement was analyzed. Results The positive rate of pituitary adenoma was 72% in routine enhancement group and 94% in dynamic enhancement group. Conclusion Dynamic enhanced scan can significantly improve the detection rate of pituitary adenoma.
