目的探讨肝脓肿炎症期病变的CT诊断与核磁共振成像(MRI)诊断的临床意义。方法 40例肝脓肿炎症患者,对其进行CT与MRI诊断,对诊断结果进行研究。结果 MRI诊断的患者胆管源性病变以及门静脉源性病变的检测数量多于CT诊断,差异具有统计学意义(P<0.05)。而临床中利用MRI诊断的患者肝动脉源性病变的检测例数与CT检测比较差异无统计学意义(P>0.05)。在CT检测中胆管源性病变呈现出高密度环,MRI则呈现出环形高信号;CT检测中门静脉源性病变呈现出低密度环,MRI则呈现出晕征;肝动脉源性病变呈现出片状T1、T2信号;相邻组织发生感染区域呈现出局灶性片影。结论临床中采用CT诊断与MRI诊断相结合,能够快速诊断出肝脓肿炎症期病变,真正做到早发现、早诊断、早治疗。
Objective To investigate the clinical significance of CT diagnosis and magnetic resonance imaging (MRI) in the diagnosis of inflammatory lesions of liver abscess. Methods Forty patients with liver abscess inflammation were diagnosed by CT and MRI, and the diagnosis results were studied. Results The number of biliary tract lesions and portal vein lesions in MRI diagnosis was more than that of CT, the difference was statistically significant (P <0.05). However, there was no significant difference in the number of cases of hepatic arterial disease detected by MRI in clinical diagnosis compared with CT (P> 0.05). In CT examination, the bile duct-derived lesions showed a high density of rings and MRI showed a ring-shaped high signal. In the CT examination, the portal vein-derived lesions presented a low-density ring while MRI showed a halo sign. The hepatic artery-derived lesions showed a Like T1, T2 signal; adjacent tissue infection area showed focal film. Conclusions The combination of CT diagnosis and MRI diagnosis in clinic can diagnose the pathological changes of liver abscess during the inflammatory phase, and achieve early detection, early diagnosis and early treatment.
