Multiangulated MR imaging of the thorax

Interpretation of CT scans and MR images is simplest when the image plane is in line with and/or perpendicular to the axis of the organ (or part of it) of interest. It is not always possible to achieve such alignment in these examinations. Angulation in one or two directions (in contrast to strict axial, coronal, and sagittal imaging) is a technique already extensively used in cardiac imaging. The authors show the use of these multiangled images in the evaluation of the aortic-pulmonary window, trachea, pulmonary artery, and pulmonary hilum and compare the images with those obtained using conventional techniques (tomography, CT, and coronal, sagittal, and axial MR imaging)
