First-Pass Perfusion and T1-weighted Dixon Imaging as Emerging Biomarkers of Pericardial Disease

Open DOI

André Vaz, Danilo de Oliveira Santana Ramos, Júlia Tupinambá Del Rey Crusoé et al.

First-pass perfusion and T1-weighted Dixon imaging are emerging biomarkers that complement conventional cardiac MRI by improving characterization of pericardial inflammation across active, chronic, and “burned-out” disease stages.

Detection of Common Thoracic Abnormalities with 0.55-T Lung MRI Compared with Chest CT: A Reader Performance Study

Open DOI

Felicia Tang, Timothy Chen, Sayedomid Ebrahimzadeh et al.

Compared with chest CT, 0.55-T MRI provided comparable diagnostic performance for consolidation and large solid nodules (≥6 mm) but had lower sensitivity for small solid nodules (<6 mm), ground-glass nodules, and emphysema.
