Abstract: | The purpose of this review is to capture the current state-of-the art of the technical aspects of multiplanar and three-dimensional
(3D) images and their thoracic applications. Planimetric and volumetric analysis resulting from volumetric data acquisitions
obviates the limitations of segmented transverse images. Among the 3D reconstruction techniques currently available, the most
recently introduced technique, i. e., volume rendering, has to be evaluated in comparison with 3D shaded surface display and
maximum or minimum intensity projection. Slabs are useful in detecting and localizing micronodular or microtubular patterns
and in analyzing mild forms of uneven attenuation of the lungs. Three-dimensional angiography is helpful in the pretherapeutic
evaluation and posttreatment follow-up of pulmonary arteriovenous malformations, in the comprehension of the postoperative
reorientation of the pulmonary vessels, in the surgical planning of pulmonary tumors, and in the diagnosis of marginated thrombi.
The systemic supply to the lung and superior vena cava syndromes are also relevant to these techniques. In acquired or congenital
tracheobronchial diseases including stenosis, extraluminal air and complex airway anatomy, multiplanar and 3D reformations
have a complementary role to both transaxial images and endoscopy. New developments are also expected in various topics such
as 3D conformal radiation therapy, planning of intraluminal bronchoscopic therapy, virtual endoscopy, and functional imaging
of the bronchial tree. Miscellaneous clinical applications are promising in the analysis of diaphragmatic morphology and pathophysiology,
in the volumetric quantification of the lung parenchyma, and in the vascular components of the thoracic outlet syndromes.
