MR Elastography Using the Gravitational Transducer.

MR elastography is a non-invasive imaging technique that provides quantitative maps of tissue biomechanical properties, i.e., elasticity and viscosity.

Differentiating Glioma Recurrence and Pseudoprogression by APTw CEST MRI.

Objectives: Recurrent glioma is highly treatment resistant due to its metabolic, cellular, and molecular heterogeneity and invasiveness. Tumor monitoring by conventional MRI has shortcomings to assess these key glioma characteristics. Recent studies introduced chemical exchange saturation transfer for metabolic imaging in oncology and assessed its diagnostic value for newly diagnosed glioma.

Assessment of Tumor Cell Invasion and Radiotherapy Response in Experimental Glioma by Magnetic Resonance Elastography.

Background: Gliomas are highly invasive brain neoplasms. MRI is the most important tool to diagnose and monitor glioma but has shortcomings. In particular, the assessment of tumor cell invasion is insufficient.

Making sense of scattering: Seeing microstructure through shear waves.

The physics of shear waves traveling through matter carries fundamental insights into its structure, for instance, quantifying stiffness for disease characterization. However, the origin of shear wave attenuation in tissue is currently not properly understood. Attenuation is caused by two phenomena: absorption due to energy dissipation and scattering on structures such as vessels fundamentally tied to the material's microstructure.

Outcomes in elderly patients undergoing endovascular thrombectomy in association with premorbid Rankin Scale scores.

Background: Endovascular thrombectomy (EVT) reduces disability in patients with acute ischemic stroke (AIS); however, its efficacy in patients aged >80 years remains unclear.

Objectives: This study aimed to assess the impact of premorbid modified Rankin Scale (pmRS) scores and age on patients with AIS undergoing EVT and the effect of EVT on functional outcome and mortality.

Methods: We conducted a retrospective cohort study and screened the Heidelberg Recanalization Registry (HeiReKa) database for patients with AIS between 1999 and 2021.
