摘要
目的探讨磁共振DCE-MRA成像技术对女性盆腔静脉血管成像中的显像方法及临床应用。方法搜集临床怀疑有女性盆腔病变行盆腔平扫+增强扫描的20例患者影像资料,增强扫描先行常规MRI平扫,再行增强扫描,增强扫描前先行冠状位蒙片扫描,增强时血管成像采用MRI-flash-3D-DCE-MRA-cor序列,根据动脉成像情况再决定扫描1~3组,中间穿插或静脉血管扫描后再运用T_(1)-fl3D-fs-tra、T_(1)-fl3D-fs-cor、T_(1)-fl3D-fs-sag序列进行脏器增强扫描,并通过减影技术提取静脉显示较好的影像进行重建。观察盆腔静脉图像的显示情况并进行评分和展示盆腔静脉病变的影像表现。结果20例患者盆腔静脉影像总体评分为4.54±0.64,图像质量好,满足诊断需求。女性盆腔静脉病变显示:盆腔静脉血管变异4例,子宫肌瘤压迫静脉导致静脉管腔狭窄或远段静脉淤血6例,左侧髂总静脉受右侧髂总动脉卡压5例,宫颈癌盆腔静脉血管管腔迂曲增粗、增多4例,盆腔静脉淤血综合征1例。结论MRI flash-3d-DCE-MRA-cor序列展示了在女性盆腔静脉显影的可行性,为进一步开展活体状态下女性盆腔血管形态学研究提供了新的技术手段。了解女性盆腔静脉的影像、分支和形态,有利于进一步认识盆腔静脉疾病,为临床诊疗提供影像学支持。
Objective To investigate the imaging method and clinical application of magnetic resonance DCE⁃MRA im⁃aging in female pelvic vein angiography.Methods The imaging data of 20 patients with suspected female pelvic lesions in our hospital who underwent pelvic plain scan and enhanced examination were collected.Routine MRI scan was performed first,followed by enhanced scan.Before enhanced scan,coronal mask scan was performed,and vascular imaging was per⁃formed during enhanced scan.Using MRI⁃flash⁃3D⁃DCE⁃MRA⁃cor sequence,according to the situation of arterial imaging,the group was divided into 1-3 groups.After interspersed or venous vessel scanning,T_(1)⁃fl3D⁃fs⁃tra,T_(1)⁃fl3D⁃fs⁃cor and T_(1)⁃fl3D⁃fs⁃sag sequences were used for organ enhancement scanning,and subtraction technology was used to select images with better venous display for reconstruction.The display of pelvic vein images was observed and scored,and the imaging mani⁃festations of pelvic vein lesions were performed.Results The overall score of pelvic vein imaging in 20 patients was 4.54±0.64,and the image quality was good,which satisfy the needs of diagnostic requirements.Female pelvic venous lesions showed:4 cases of pelvic venous vascular variation,6 cases of venous lumen stenosis or distal venous congestion caused by uterine fibroids,5 cases of the left common iliac vein is compressed by the right common iliac artery,4 cases of cervical cancer pelvic venous blood vessels lumen tortuous and thickened and increased.1 case of pelvic venous congestion syn⁃drome.Conclusion MRI⁃flash⁃3D⁃DCE⁃MRA⁃cor sequence shows the feasibility of female pelvic veins,which provides a new technical means for further research on the morphology of female pelvic vessels in vivo imaging.Understanding the ima⁃ges,branches and shapes of female pelvic veins will help us to further understand pelvic venous diseases and provide ima⁃ging support for clinical diagnosis and treatment.
