Three paracardiac masses (1 thymic cyst, 2 thymomas) were studied by magnetic resonance imaging (MRI) using spin-echo, multi-echo, and gradient-echo sequences (cine-MR). MRI showed: a pedunculate cystic lesion, typical for thymic origin, in Case 1; cardiac and pulmonary infiltration, and 3 intracardiac metastases, in Case 2; cardiovascular compression but not infiltration, in Case 3. In 3/3 cases MRI was superior to transthoracic echocardiography (TTE), and in 2/2 MRI was superior to computed tomography (CT), not performed in Case 2 (allergy to contrast agents). MRI may be considered the most important technique to evaluate cardiovascular involvement by thymic neoplasms. MRI should be performed after TTE and makes CT unnecessary.
通过磁共振成像（MRI），利用自旋回波、多回波及梯度回波序列（电影磁共振）对三个心旁肿块（1个胸腺囊肿、2个胸腺瘤）进行了研究。MRI显示：病例1中为有蒂的囊性病变，典型的胸腺起源；病例2中心脏和肺部浸润以及3个心内转移灶；病例3中存在心血管受压但无浸润。在3例患者中，MRI均优于经胸超声心动图（TTE），在2例患者中，MRI优于计算机断层扫描（CT），病例2未进行CT检查（对造影剂过敏）。MRI可被视为评估胸腺肿瘤累及心血管的最重要技术。MRI应在TTE之后进行，从而无需进行CT检查。
