Key result
Breath-hold gadolinium-enhanced 3D MR angiography identified left atrial invasion at 2 sites and proximal pulmonary vein invasion at 5 sites in 20 patients with lung cancer.
Why the study?
Can breath-hold gadolinium-enhanced 3D MR angiography accurately assess the invasion of the pulmonary vein and left atrium in patients with lung cancer?

Can breath-hold gadolinium-enhanced 3D MR angiography accurately assess the invasion of the pulmonary vein and left atrium in patients with lung cancer?
Breath-hold gadolinium-enhanced 3D MR angiography is a suitable imaging modality for assessing the extent of pulmonary vein and left atrial invasion in lung cancer patients to guide surgical resection.
May aid preoperative planning for lung cancer resection; leaves open accuracy and outcome impact without prospective validation.
PURPOSE: The purpose of this work was to evaluate the ability of breath-hold gadolinium-enhanced three-dimensional (3D) MR angiography to assess the invasion of the pulmonary vein and the left atrium by lung cancer. METHOD: Gadolinium-enhanced 3D MR angiography was performed in 20 consecutive patients with lung cancer. RESULTS: At two sites with left atrial invasion shown by MR angiography, associated partial resection of the left atrium was performed. At five sites with invasion of the proximal pulmonary vein within 1.5 cm from the left atrium on MR, partial resection of the left atrium was performed at one site, and the pulmonary vein was resected at the intrapericardial portion at three sites. At two sites with invasion of the proximal pulmonary vein 1.5 cm more distal to the left atrium, the pulmonary vein was resected at the extrapericardial portion. CONCLUSION: Breath-hold gadolinium-enhanced 3D MR angiography is suitable for assessing invasion of the pulmonary vein and the left atrium by lung cancer.
