title: [High-resolution MR imaging of the mediastinum and hilus of the lung using surface-coils].
abstract: High-resolution MR imaging using surface-coils (Helmholtz-coil) was performed on patients with hilar lung cancer and healthy volunteers. We evaluated the clinical usefulness of this technique compared with MR imaging performed with a conventional body-coil. Although the signal-to-noise ratio was slightly decreased, normal anatomic structures, hilar masses, and enlarged lymph nodes were distinctly visualized in comparison with those on MR images obtained with a body-coil. High-resolution MR imaging with the Helmholtz-coil seemed to be useful for the evaluation of mediastinal and hilar disease, and may able to supplant MR imaging with a conventional body-coil in routine examinations.
