The FIESTA (fast imaging employing steady-state acquisition) ultrafast pulse sequence provides high-resolution images with outstanding image contrast and high signal-to-noise ratio relative to the single-shot fast spin-echo (SSFSE) sequence. The purpose of this article is to illustrate the utility of the FIESTA sequence in oncologic imaging.
Although the FIESTA technique cannot replace standard imaging techniques, it can be used as an excellent adjunct to conventional T1-and T2-weighted sequences for abdominal imaging and for screening the entire abdomen and pelvis at the beginning of the examination. In addition, the motion-insensitive FIESTA sequence is useful in surgical planning, particularly in patients with retroperitoneal tumors and pancreatic cancer because it offers excellent visualization of the vascular anatomy.
与单次激发快速自旋回波（SSFSE）序列相比，快速成像稳态采集（FIESTA）超快脉冲序列可提供具有出色图像对比度和高信噪比的高分辨率图像。本文旨在阐述FIESTA序列在肿瘤成像中的应用价值。
尽管FIESTA技术不能替代标准成像技术，但它可作为传统T1加权和T2加权序列的极佳辅助手段，用于腹部成像以及在检查开始时对整个腹部和骨盆进行筛查。此外，对运动不敏感的FIESTA序列在手术规划中很有用，特别是对于腹膜后肿瘤和胰腺癌患者，因为它能很好地显示血管解剖结构。
