This work demonstrates the application of single-breathold thoracic MRI with balanced steaty-state free precession half-radial dual-echo readout technique (bSTAR) in human subjects. The proposed imaging technique combines a minimal-TR acquisition with a smoothly interleaved Archimedean spiral trajectory, which results in markedly improved signal intensity from low proton lung parenchyma tissue, improved visualization of the pulmonary vascular tree as well as a successful mitigation of eddy current and cardiac motion artifacts.
