HASTE序列在磁共振尿路成像技术的临床应用

目的:探讨HASTE序列在磁共振尿路成像的检查技术及临床应用价值。方法:采用HASTE序列、3D重T2WI技术以及口服或静脉注射利尿剂、对73例病人行磁共振尿路成像。然后对前二者图像进行质量评价,根据逆行尿路造影及术后结果对照分析尿路梗组性疾病的MRU影像学特征,讨论HASTE序列在尿路梗阻疾病中的诊断价值。结果:HASTE序列MRU能清楚显示各类尿路梗组性疾病的形态学改变,尤其对静脉尿路造影(IVU)不能显影者效果更好,73例病人中HASTE序列+常规MRI检查阳性率100%。结论:HASTE序列不受呼吸运动影响,成像质量好,扫描速度快,能更好地显示尿路梗阻部位、程度,与MRI结合能更清晰地诊断尿路梗阻的病因,可满足临床诊断要求。

Objective：To investigate the HASTE sequence in magnetic resonance urography examination techniques and clinical applications.Methods：Using HASTE sequences,3D-heavily T2WI technology,and oral or intravenous diuretics,of 73 patients were treated with magnetic resonance urography.And then the first two image quality evaluation,according to the results of retrograde urography,and comparative analysis of postoperative urinary tract diseases,stem group MRU imaging features to discuss the HASTE sequences in urinary tract obstruction in the diagnosis of the disease.Results：HASTE sequence MRU can show clearly the various types of stem group of diseases,urinary tract morphological changes,especially for intravenous urography（IVU）can not imaging were better,73 cases of patients with HASTE Conventional MRI sequences ＋ The positive rate of 100%.Conclusion：HASTE sequence without respiratory motion effects,image quality,scanning speed,better able to show parts of urinary tract obstruction,extent,and MRI diagnosis of the binding energy more clearly the cause of urinary tract obstruction can meet the clinical diagnostic requirements.
