To assess the usefulness of cine-magnetic resonance imaging (cine-MRI)in the evaluation of chest wall invasion, we compared the results of cine-MRI with those of computed tomography (CT) and ultrasonography (US).
Eleven patients were examined who had no pain and who were difficult to diagnose by routine examinations. MRI was performed with a Magnetom SP/4000, 1.5T unit (Siemens, Germany). For cine imaging, continuous turbo-FLUSH (ultra fast low angle shot) images were obtained at an orthogonal section to the chest wall during slow deep breathing. A CT scan was performed using a TCT 900S or Super Helix (Toshiba, Japan) at 1 cm intervals, with section thicknesses of 1 cm throughout the entire chest. US was performed with a model SSA-270A (Toshiba, Japan) with 7.5-MHz linear array scanners (PLF-705S; Toshiba, Japan).
Sensitivity, specificity and accuracy were 67%, 75% and 73% for cine MRI, 67%, 63% and 64% for CT, 33%, 75% and 64% for US, respectively.
These results indicate that cine MRI is potentially useful for the diagnosis of chest wall invasion of lung cancer.
为了评估电影磁共振成像（cine-MRI）在评估胸壁侵犯方面的效用，我们将cine-MRI的结果与计算机断层扫描（CT）和超声检查（US）的结果进行了比较。
对11例无疼痛且通过常规检查难以诊断的患者进行了检查。使用德国西门子公司的Magnetom SP/4000 1.5T设备进行MRI检查。对于电影成像，在缓慢深呼吸期间，在与胸壁正交的层面上获取连续的快速扰相梯度回波（ultra fast low angle shot）图像。使用日本东芝公司的TCT 900S或Super Helix进行CT扫描，层间距为1 cm，整个胸部的层厚均为1 cm。使用日本东芝公司的带有7.5 MHz线性阵列扫描仪（PLF-705S）的SSA-270A型号进行超声检查。
cine-MRI的敏感性、特异性和准确性分别为67%、75%和73%，CT的分别为67%、63%和64%，US的分别为33%、75%和64%。
这些结果表明cine-MRI在诊断肺癌胸壁侵犯方面可能是有用的。
