Quiet T1‐weighted imaging using PETRA: Initial clinical evaluation in intracranial tumor patients

To compare the lesion contrast and signal to noise ratio (SNR) obtained with T1‐weighted pointwise encoding time reduction with radial acquisition (PETRA) to those of Magnetization‐Prepared RApid Gradient‐Echo (MPRAGE) for contrast‐enhanced imaging of primary and metastatic intracranial tumors, and to investigate whether PETRA is able to reduce acoustic noise for improved patient comfort.
