Abstract
The feasibility and diagnostic value of real-time magnetic resonance imaging (RT-MRI) for the diagnosis of acute pulmonary embolism (PE) was evaluated by comparing RT-MRI and magnetic resonance angiography (MRA). In 39 consecutive patients with suspected PE, real-time true fast imaging with steady-state precession (TrueFISP) was prospectively compared with contrast-enhanced MRA on a 1.5-T MR scanner. The TrueFisp sequence used allowed the acquisition of T2-weighted images at 0.4 s/image so that the pulmonary vasculature could be visualized in three orientations in <3 min without the need for breath holding or contrast media application.
