3T磁共振THRIVE技术在腹部疾病中应用价值

摘要

Objective To investigate the application value of THRIVE (Tl High Resolution Isotropic Volume Examination) technique of MRI in the diagnosis of abdominal diseases. Methods THRIVE technique was applied to the scan of 67 cases with upper abdominal diseases and its value was analyzed. Results 45 cases with diseases of liver, gallbladder, pancreas and splee, 10cases with kidney and adrenal gland, 2 cases with abdominal aneurysm, 5 case with primary vetro-peritoneal tumor and 1 case with testis, 1 case with ovarian tumor in pelvic cavity, 1 case with carcinoma of stomach and 1 case with carcinoma of colon, 1 case with abscess of peritoneal space were found by THRIVE sequence. The positive rate was 97.1％. The focus of infection in 2 cases were not found by THRIVE sequence, and the negative rate was 2.9％. Conclusion THRIVE technique of MRI could satisfy the clinical diagnostic need in the examination of upper abdominal diseases.THRIVE technique has features of high-resolution imaging with large FOV coverage and excellent fat suppression.%目的 探讨3T MR THRIVE (T1 High Resolution Isotropic Volume Examination)技术在腹部疾病中的应用价值.方法 采用THRIVE序列对67例腹部疾病进行扫描,分析其应用价值.结果 THRIVE技术发现肝胆胰脾病变45例,肾及肾上腺病变10例,腹主动脉瘤2例,原发性腹膜后肿瘤5例,盆腔内卵巢及阴囊肿瘤各1例,胃癌和结肠癌各1例,腹腔脓肿1例.阳性率约为97.1%.有2例在THRIVE技术中病灶没能显示,阴性率约为2.9%.结论 MRI THRIVE技术的特点是空间分辨率高,扫描范围大、速度快,具有良好的脂肪抑制作用,在腹部疾病检查中能够满足临床的诊断需要.
