[Magnetic resonance angiography for the diagnosis of pulmonary nodules--clinical applications of 3D FAST FE technique].
Three-dimensional (3D) magnetic resonance angiography (MRA) was obtained by means of the 3D Fourier transfer (FT) field echo (FE) technique (repetition time 15-17 msec, echo time 3-8 msec, flip angle 15 degrees, slab thickness 67 mm) in 14 patients with pulmonary nodules during one breath hold. 3D MRA was evaluated in comparison with the spin echo method. Subsegmental pulmonary arteries were highly definable (78.5%: right lung), and all pulmonary nodules were well identified and had fewer artifacts than images obtained by the spin echo (SE) technique. In conclusion, 3D MRA was found to be a promising method in the assessment of pulmonary nodules with MRI.
