		Abbreviated Prostate MR Imaging Protocols Watch the Video Chan Kyo Kim Multiparametric prostate MRI (mpMRI) protocols that consist of T2-weighted imaging (T2WI), diffusion-weighted imaging (DWI), dynamic contrast-enhancing imaging, and T1-weighted imaging provide excellent performance for evaluating prostate cancer (PCa). Recently, abbreviated prostate MRI protocols (or biparametric MRI, bpMRI) that consist of only T2WI and DWI continue to gain support for detecting PCa. It can offer several advantages over mpMRI. In this presentation, my talks would introduce bpMRI protocols and furthermore, advantages and limitations of bpMRI protocols are discussed.
		Abbreviated Liver MR Protocols Video Permission Withheld Kartik Jhaveri Increasing utilization and demand of Liver MRI presents both challenges and unique opportunities. Strategies incudes optimization and development of faster pulse sequences, hybrid imaging, automated exam planning and reducing pulse sequences acquired. The latter approach essentially amounts to abbreviated Liver MRI protocols. Various approaches have been described such as acquiring noncontrast sequences only , dynamic postcontrast series only or a combination of T2,DWI and delayed postcontrast images for HCC screening or surveillance and detection and surveillance of liver metastases. Noncontrast Multiparametric MRI providing liver fat ,iron and fibrosis quantification is also being increasing utilized as a replacement for liver biopsy.
