Magnetic resonance (MR) images (0.5 and 1.5 T) and thin section CT scans were obtained in 17 cadaveric lungs (11 fixed, 6 both pre and post fixation). Standard T1-weighted spin echo (SE) sequences were used for all lungs. In six lungs, additional gradient-refocused echo (GRE) sequences were also obtained. The MR images and CT scans were compared to corresponding gross and microscopic pathologic sections. In all cases, MR SE sequences proved comparable to CT for delineation of normal anatomic structures as well as a range of pathologic conditions, including both air space and interstitial disease. Although image quality was markedly degraded on GRE compared to SE images, they did permit visualization of pulmonary vasculature and focal pathology.
对17个尸体肺脏（11个固定，6个固定前后均有）进行了磁共振（MR）成像（0.5T和1.5T）及薄层CT扫描。所有肺脏均使用标准T1加权自旋回波（SE）序列。在6个肺脏中，还获取了额外的梯度重聚回波（GRE）序列。将MR图像和CT扫描与相应的大体和显微镜病理切片进行比较。在所有病例中，MR SE序列在描绘正常解剖结构以及一系列病理状况（包括气腔和间质性疾病）方面被证明与CT相当。尽管与SE图像相比，GRE图像质量明显下降，但它们确实能显示肺血管系统和局灶性病变。
