摘要
MRI由于无电离辐射,在肺结节筛查中具有CT不可比拟的无损伤优势。本文简要介绍MRI各常用序列[快速自旋回波(TSE)、短反转时间反转恢复(STIR)、半傅立叶采集单次激发快速自旋回波(HASTE)、梯度回波(GRE)]在肺结节检出中的价值及各自的优缺点。
MRI is superior to CT in the detection of pulmonary nodules, because it is an imaging method without ionizing radiation. The advantage and disadvantage of each common sequence [turbo spin echo(TSE), short inversion time inversion recovery(STIR), half-Fourier acquisition single-shot turbo spin echo(HASTE), gradient echo(GRE)] in the detection of pulmonary nodules are briefly described in the present paper.
