Summary: MRI-guided radiotherapy systems combine adaptive radiotherapy and biological targeting, updating treatment plans regularly to accommodate observed treatment responses. Quantitative imaging biomarkers are necessary for predicting treatment outcomes early in the process. This review provides an overview of the current evidence on the potential of quantitative MRI measurements as imaging biomarkers in MRI-guided radiotherapy systems.

Summary: This study used MRI and optical modeling to investigate the effects of water transport, lens curvature, and gradient refractive index (GRIN) on the power of the mouse lens as it ages. The results showed changes in lens shape, GRIN, and lens power as the mouse ages. These findings can help improve our understanding of lens power changes during development in humans.

Summary: Nanomaterials are crucial in the development and application of hyperpolarized materials for MRI. They can function as both directly imaged hyperpolarized materials, carriers for hyperpolarized gases, and catalysts for generating hyperpolarized substrates. This article provides an overview of recent developments in these three application possibilities, highlighting carbon-based materials for direct imaging. The importance of nanomaterials in MRI is discussed, including their biocompatibility and imaging experiments.

Summary: This study aimed to investigate whether dynamic contrast-enhanced (DCE)-MRI and vascular water exchange imaging (VEXI) could produce comparable water exchange across the blood-brain barrier (WEXBBB) in high-grade glioma (HGG) patients. The results showed that both methods demonstrated consistency and reliability in measuring WEXBBB.

Summary: This study proposes a simple denoising method using a one-dimensional convolutional neural network (1D-CNN) and deep learning to learn from a low-noise dataset, and applies it to high-noise datasets. The results show that this method produces DWI images that are more similar to noise-free ground truth compared to other methods, and also shows promising results in diffusion metrics and tractography.

Summary: Magnetic resonance imaging is sensitive to water and can be used for 3D mapping of soil water processes. Ultrafast detection pulse sequences allow for detection of rapidly relaxing fractions of water in natural porous media. ZTE and UTE sequences have the potential to detect all water fractions with sufficiently broad bandwidths.

Summary: The blood-brain barrier (BBB) is crucial for maintaining homeostasis within the brain and is increasingly associated with various neurological diseases. MRI techniques, such as dynamic contrast-enhanced and dynamic susceptibility contrast MRI, are commonly used for noninvasive assessment of BBB integrity. Other alternative techniques targeting different aspects of the BBB, such as using endogenous markers like water and glucose, are also available. A comprehensive overview of current MRI techniques to assess BBB condition and potential applications in disease is provided, with discussions on improvements needed for clinical applicability.

Summary: In recent years, exceedingly small magnetic iron oxide nanoparticles (ES-MIONs) have emerged as promising T-1 contrast agents for magnetic resonance imaging (MRI) due to their advantages over traditional contrast agents and conventional magnetic nanoparticles. This review summarizes the synthesis methods, surface modifications, T-1-MRI visual strategies, and imaging-guided cancer therapies of ES-MIONs, aiming to attract extensive interest from researchers and promote their involvement in the development of ES-MIONs based nanoplatforms for tumor theranostics.
