The aim of this paper was to assess the diagnostic value of magnetic resonance (MR) fluoroscopy in the study of oesophageal motility disorders and to compare MR fluoroscopy results with those of manometry and barium contrast radiography. Twenty-five subjects referred for dysphagia and three patients in follow-up after pneumatic dilatation of the lower oesophageal sphincter to treat severe achalasia underwent esophageal manometry, barium contrast radiography and MR fluoroscopy. Examinations were performed on a 1.5 T scanner. Dynamic turbo- fast low angle shot (turbo-FLASH) sequences acquired during oral contrast agent administration were used to perform MR fluoroscopy. MR fluoroscopy correctly diagnosed achalasia in nine patients, uncoordination of esophageal body motility in ten and scleroderma oesophagus in one. Diagnostic performance was satisfactory, with a sensitivity of 87.5% and a specificity of 100% in the general depiction of motility alterations. Our work demonstrates that MR fluoroscopic examination in subject affected by oesophageal motility disorders is feasible and can properly depict motility and morphology alterations, achieving correct diagnosis in the majority of cases. Studies on larger populations are necessary to obtain statistically significant results.
本文旨在评估磁共振（MR）透视在食管动力障碍研究中的诊断价值，并将MR透视结果与测压法和钡剂造影结果进行比较。25例因吞咽困难就诊的患者以及3例在接受食管下括约肌气囊扩张治疗严重贲门失弛缓症后进行随访的患者接受了食管测压、钡剂造影和MR透视检查。检查在1.5T扫描仪上进行。在口服造影剂期间采集的动态快速低角度激发（turbo-FLASH）序列用于进行MR透视。MR透视正确诊断出9例贲门失弛缓症、10例食管体部动力不协调和1例硬皮病食管。诊断性能令人满意，在动力改变的总体描述中，敏感性为87.5%，特异性为100%。我们的研究表明，对受食管动力障碍影响的患者进行MR透视检查是可行的，并且能够正确描绘动力和形态改变，在大多数情况下实现正确诊断。需要对更多人群进行研究以获得具有统计学意义的结果。
