目的:研究CT灌注成像技术在甲状腺病变临床诊断中的应用价值。方法:对55例甲状腺病变患者采取CT灌注成像,灌注数据传递至独立工作站(Release3.0.1.3200)后,采用perfusion灌注成像软件进行数据处理。最后进行灌注成像分析。结果:良性肿瘤组的BF为(329.46±135.03)mL·100g-1·min-1,BV为(8.13±5.28)mL/100g,MTT为(3.67±2.65)s,PS为(42.74±25.36)mL·100g-1·min-1。恶性肿瘤组的BF为(332.71±139.12)mL·100g-1·min-1,BV为(8.02±5.42)mL/100g,MTT为(3.89±2.59)s,PS为(55.04±21.86)mL·100g-1·min-1。两组通过对比后发现BF、PS差别有明显统计学意义性(P<0.05),而BV、MTT值无明显统计学意义(P>0.05)。结论:CT灌注成像技术在甲状腺病变临床诊断中具有较高的参考价值。
Objective: To study the value of CT perfusion imaging in the clinical diagnosis of thyroid lesions. Methods: CT perfusion imaging was performed on 55 cases of thyroid lesions. Perfusion data were sent to an independent workstation (Release3.0.1.3200) and perfusion perfusion imaging software was used to process the data. Finally perfusion imaging analysis. Results: BF was (329.46 ± 135.03) mL · 100g-1 · min-1 in benign tumor, BV was (8.13 ± 5.28) mL / 100g, MTT was (3.67 ± 2.65) s and PS was (42.74 ± 25.36) mL · 100g-1 · min-1. The BF was (332.71 ± 139.12) mL · 100g-1 · min-1 in the malignant tumor group, the BV was (8.02 ± 5.42) mL / 100g, the MTT was (3.89 ± 2.59) s and the PS was (55.04 ± 21.86) mL · 100g-1 · min-1. The differences of BF and PS between the two groups were statistically significant (P <0.05), while the values of BV and MTT were not statistically significant (P> 0.05). Conclusion: CT perfusion imaging in the clinical diagnosis of thyroid disease has a high reference value.
