MRI has gained increased attention for whole-body screening of tumor metastasis. The commonly used sequences are STIR and DW-EPI. However, both are SNR limited and require multiple signal averages increasing the total scan time. In addition, DW-EPI images are also subject to distortion in larger FOVs, and are typically limited to low resolution, axial plane imaging. The primary objective of whole-body screening is to minimize the background tissue signal while simultaneously highlighting tumor signal in a rapid acquisition. Such a technique is presented in this work using SSFSE readout while suppressing signal from fat, fluid and blood vessels.
