Images were acquired on a 3.0T whole body MR scanner (General Electric, Milwaukee, WI) using a standard quadrature head coil. A high resolution 3D T1-weighted SPGR-IR sequence used the following parameters: TR=45, TE=20, FA=45, 2562 matrix, 240 mm2 FOV (.9 × .9 mm2 in-plane), 1.7 mm slice thickness, coronal plane. Scan time was 9′ 24″. A neuroradiologist (JT) evaluated anatomical images for motion artifact and the EPI T2* images for gross structural abnormalities, particularly encephalomalacia. No studies were excluded.
