Synopsis

Pulmonary imaging traditionally uses techniques utilizing ionizing radiation such as x-rays and CT. Pediatrics, pregnant patients, and patients who will be exposed multiple times over long periods of time would benefit from a non-ionizing modality. MRI does not use ionizing radiation but suffers from low signal from the lungs and breathing motion artifact. We are proposing a novel MRI technique to combat these issues: a 3-dimensional Dual-Echo FID Ultra-short Echo Time (3D DE UTE) sequence utilizing Rosette k-space acquisition. Preliminary results demonstrated better pulmonary artery segmental branches and pleural wall definition compared to other commercially available MRI sequences.
