For the past few decades, ultrasound has been extensively investigated to promote clot lysis for the treatment of stroke, myocardial infarction, and acute peripheral arterial occlusions, with or without the use of tPA or contrast agents. In the age of modern minimal invasive techniques, magnetic ...

MRI of acute ischemic stroke The advent of new MR techniques such as perfusion and diffusion weighted imaging has revolutionized diagnostic imaging in stroke. In some institutions, MRI... C Oppenheim,O Naggara,C Arquizan,... - 《Journal De Radiologie》 被引量: 22发表: 2005年 Diagnostic imag...
Magnetic resonance imaging (MRI) is the primary clinical tool for detecting soft tissue pathology due to high soft tissue contrast. It is non-invasive, does not involve patient exposure to ionizing radiation, and allows for quantification of tissue morphology. Traditionally, MRI is not practical as...
with contrast-enhanced T1 MRI. Indeed, MRgFUS has been widely used to enhance anti-cancer drug delivery to pediatric brain tumors in mice [87] or polymeric nanoparticles in healthy rats [35,88]. One concern with FUS BBB opening is the need to titrate the energy of FUS and the dose of...

In principle, conventional X-ray attenuation-based imaging is ideal for materials with high absorption properties. However, the attenuation contrast becomes extremely poor without a significant increase in dose deposition, while low-Z materials are under investigation with high-energy X-rays. Recently,...
