Optimization of region-of-interest sampling strategies for hepatic MRI proton density fat fraction quantification.
Clinical trials utilizing proton density fat fraction (PDFF) as an imaging biomarker for hepatic steatosis have used a laborious region-of-interest (ROI) sampling strategy of placing an ROI in each hepatic segment. ⋯ 3 Technical Efficacy: Stage 2 J. Magn. Reson. Imaging 2018;47:988-994.

Observational StudyQuantitative susceptibility mapping as a monitoring biomarker in cerebral cavernous malformations with recent hemorrhage.
Quantitative Susceptibility Mapping (QSM) MRI allows accurate assessment of iron content in cerebral cavernous malformations (CCM), and a threshold increase by 6% in QSM has been shown to reflect new symptomatic hemorrhage (SH) in previously stable lesions. ⋯ 1 Technical Efficacy: Stage 4 J. Magn. Reson. Imaging 2018;47:1133-1138.

Intravoxel incoherent motion diffusion-weighted imaging in assessing bladder cancer invasiveness and cell proliferation.
Nonmuscle-invasive bladder cancer (NMIBC, Stage T1 or lower) is treated with transurethral resection (TUR), while muscle-invasive bladder cancer (MIBC, Stage T2 or more) requires neoadjuvant chemotherapy before radical cystectomy. Hence, preoperative differentiation is vital. ⋯ 1 Technical Efficacy: Stage 3 J. Magn. Reson. Imaging 2018;47:1054-1060.
