[MRI evaluation in tracheal pathology. Comparison with tomography and x-ray computed tomography. Apropos of 30 cases]

The authors report a standardised comparison between MRI, CT and Tomography, in 30 cases of tracheal lesions (postintubation, tumors, external compressions and invasions). They conclude on the superiority of MRI because of its multiplanar visualisation, its soft-tissue contrast resolution and its capability to differentiate inflammatory granuloma.
