Adams LC, et al. - Researchers sought to test the potential of unenhanced cardiac- and respiratory-motion-corrected 3-dimensional steady-state free precession (3D-SSFP) magnetic resonance imaging (MRI) for the assessment of inferior vena cava (IVC) thrombus in patients with clear-cell renal cell carcinoma (cRCC) vs standard contrast-enhanced (CE)-MRI and CE-computed tomography (CT). Findings suggested that an accurate assessment of IVC thrombus could be achieved with 3D-SSFP in cRCC patients without the need for contrast medium administration, being superior to standard MRI and CT.
