Fig 1. Case 1. A, Preoperative midsagittal FSE T2-weighted image at 1.5T (TR, 4000 ms; TE, 75.8 ms; echo train length (ETL) 20; 2 NEX; acquisition time (AT), 3'36" for 11 4-mm-thick sections): swelling and abnormal hyperintensity of the diseased segment of the cord were obvious. B, Intraoperative midsagittal FSE T2-weighted image at 3T after closure of the surgical wound. The 2 elements had been put on the midline of the patient's back in the cranial-caudal direction without capability of SENSE acquisition because of insufficient overlapping between coils. Inflatable balloon of the laryngeal tube was visible (arrow). IQ was rated excellent by using following PSPs: TR, 2209 ms; TE, 120 ms; ETL 20, 4 NEX; no SENSE acceleration factor; AT: 4'56" for 11 4-mm-thick sections.
