为探究 4D-PC（相位对比）与 2D-PC 血流在无造影剂情况下定量 MRI 血流分析的可靠性，研究人员开展针对法洛四联症修复术后（rToF）成人的回顾性研究。结果显示 4D-PC MRI 可靠但可能低估肺反流。该研究为心脏检查提供新方向。 本研究回顾性分析了 2021 年至 2023 年 ...

Healing a broken bone can take months, and knowing whether recovery is on track often takes just as long. Doctors typically rely on periodic X-rays, capturing two-dimensional images to see how the ...

本研究针对阿尔茨海默病(AD)早期诊断缺乏非侵入性生物标志物的难题，通过3.0T MRI测量脑半卵圆中心水平皮质动脉搏动指数(PICSO)，发现AD患者PICSO显著增高且与类淋巴功能指标DTI-ALPS指数负相关，为AD的类淋巴功能障碍机制提供了新型影像学评估工具。 在神经退行 ...

In a study published in the Journal of Biomechanics, researchers sought to seek longtime assumption about wrists, while also finding gender wrist differences that could help inform and guide future ...

We use our wrists constantly, but how do they work? Researchers have now demonstrated a longtime assumption about individuals' right and left wrists, while also finding differences between wrists of ...

Heath Pardoe is an investigator on NHMRC grant 1020526, "Is stroke neurodegenerative? A longitudinal study of changes in brain volume and cognition following stroke" CIA Amy Brodtmann, and NIH grant ...

We use our wrists constantly, but how do they work? In a just-published Journal of Biomechanics article, the researchers proved a longtime assumption about individuals' right and left wrists, while ...

A twist on magnetic resonance imaging that does not require gadolinium contrast appears to be as effective as standard imaging at detecting prostate cancers, according to a new study in JAMA. Experts ...

MRI stands for magnetic resonance imaging. It is a type of scan that creates pictures using magnetism and radio waves. MRI scans produce pictures from angles all around the body and shows up soft ...
