Abstract

Objective: Magnetic resonance thoracic ductography (MRTD), concomitant with blood vessel imaging, provides useful anatomical information. The purpose of this study was to assess the visibility of the thoracic duct and blood vessels simultaneously by MRTD using balanced turbo-field-echo (bTFE) and turbo spin-echo (TSE).

Methods: MRTDs concomitant with blood vessel imaging on bTFE and TSE were obtained for 10 healthy volunteers with a 1.5T-magnetic resonance unit. Visibility of the thoracic duct, blood vessels in the thoracic region; motion artifacts; and overall image quality were scored by two radiologists using three-to-five-point scales; those were compared between bTFE and TSE.

Results: The thoracic duct was generally well-visualized on MRTD sequences. The upper part of the thoracic duct was better visualized on TSE than on bTFE (p < 0.05). The blood vessels were well visualized on bTFE and TSE; the bilateral subclavian arteries and the right subclavian veins were better visualized on TSE than on bTFE (all p < 0.05). Motion artifacts and overall image quality were better on TSE than on bTFE (p = 0.0039 and 0.0020, respectively).

Conclusion: MRTD concomitant with blood vessel imaging on TSE has better visibility of the thoracic duct and blood vessels than bTFE.

利用MRI同时显示胸导管和血管:平衡涡场回波和自旋回波的比较。

目的:磁共振胸导管造影(MRTD)与血管造影相结合，提供有用的解剖学信息。本研究的目的是利用平衡涡轮场回波(bTFE)和涡轮自旋回波(TSE)同时评估MRTD对胸导管和血管的可见性。方法:采用1.5 t磁共振仪对10例健康志愿者进行bTFE和TSE血管成像。胸管，胸区血管的可见性;运动构件;整体图像质量由两名放射科医生用三到五分制评分;bTFE与TSE比较。结果:在MRTD序列上，胸导管大体清晰可见。胸管上段在TSE上的显像优于bTFE (p < 0.05)。bTFE和TSE显示血管清晰;TSE对双侧锁骨下动脉和右侧锁骨下静脉的显像优于bTFE(均p < 0.05)。运动伪影和整体图像质量在TSE上优于bTFE (p分别= 0.0039和0.0020)。结论:MRTD联合血管显像对TSE的胸导管和血管的可见性优于bTFE。
