Progress and application of functional magnetic resonance imaging in acute kidney injury

Linchuang shenzangbing zazhi
Acute kidney injury （AKI） is a globally highly prevalent clinical syndrome characterized by a sudden deterioration of renal function. It occurs in a variety of clinical conditions and its severity is closely associated with increased subsequent mortality，

A Method for Imaging the Ischemic Penumbra with MRI Using Intravoxel Incoherent Motion

American Journal of Neuroradiology
In acute ischemic stroke, the amount of "local" CBF distal to the occlusion, ie, all blood flow, whether supplied antegrade or delayed and dispersed through the collateral network, may contain valuable information regarding infarct growth rate and treatment response.
