Single-shot gradient- and spin-echo (SS-GRASE) technology is a useful technique for IVIM imaging of lung cancer
FIGURE 1. A nodular lesion (arrow) in the right upper lobe. A, T2WI-SPIR. B, GRASE-IVIM (b = 800 s/mm2 ). C, TSE-IVIM (b = 800 s/mm2 ). D, EPI-IVIM (b = 800 s/mm2 ).E,T2WI fused with GRASE-IVIM. F, T2WI fused with TSE-IVIM.G, T2WI fused with EPI-IVIM. The distortion and displacement of the lesion are shown on EPI-IVIM (arrow). On TSE and GRASE-IVIM ,the lesion, along with its air bronchus, can be clearly shown. Fused images showed that GRASE and TSE-IVIM is perfectly matched with T2WI-SPIR.
