Segmental pulmonary arteries: two-dimensional and three-dimensional time-of-flight magnetic resonance angiography.

The authors compared two-dimensional (2D) and three-dimensional (3D) time-of-flight (TOF) magnetic resonance angiography in ten healthy volunteers to establish which of two techniques is more effective in representing the pulmonary segmental arteries. No respiratory trigger or electrocardiogram gating was used. Presaturation pulses were used to eliminate venous flow.

[Magnetic resonance angiography in the study of pulmonary veins: TOF 3D versus 2D].

The aim of this work was to optimize the magnetic resonance angiography (MRA) technique for the selective study of the pulmonary veins. Twenty consecutive patients (13 men and 7 women; mean age: 30.5 years) were examined.

To assess the diagnostic and medicolegal contribution of Computed Tomography (CT) in patients with craniocerebral, maxillofacial, neck and spine gunshot wounds, we submitted to CT 106 patients with gunshot wounds examined over a 7-year period (February, 1988 to December, 1994). Twenty-four of them had craniocerebral injuries (23%), 9 maxillofacial (8%), 8 neck (8%) and 10 vertebral (9%) injuries. Emergency CT demonstrated the mechanism of the injury, the bullet path and site, the site of bone and/or metallic fragments, and damage extent.

[Magnetic resonance angiography of the origin of the supraaortic trunks: the tridimensional time-of-flight with single volume technique].

This work was aimed at studying the origin of the epiaortic vessels with Magnetic Resonance Angiography (MRA). Twenty normal volunteers (mean age: 21.5 years) were examined with MRA with a superconductive magnet at 1 T (Impact).
