In vivo laser Doppler holography of the human retina

, 2018
The eye offers a unique opportunity for non-invasive exploration of cardiovascular diseases. Optical angiography in the retina requires sensitive measurements, which hinders conventional full-field laser Doppler imaging schemes.

Ultrasound localization microscopy to image and assess microvasculature in a rat kidney. [PDF]

, 2017
The recent development of ultrasound localization microscopy, where individual microbubbles (contrast agents) are detected and tracked within the vasculature, provides new opportunities for imaging the vasculature of entire organs with a spatial ...

Multifunctional in vivo vascular imaging using near-infrared II fluorescence

, 2012
In vivo real-time epifluorescence imaging of mouse hindlimb vasculatures in the second near-infrared region (NIR-II, 1.1~1.4 microns) is performed using single-walled carbon nanotubes (SWNTs) as fluorophores.

Animal models of ischaemic stroke and characterisation of the ischaemic penumbra [PDF]

, 2018
Over the past forty years, animal models of focal cerebral ischaemia have allowed us to identify the critical cerebral blood flow thresholds responsible for irreversible cell death, electrical failure, inhibition of protein synthesis, energy depletion ...

Doppler tissue imaging.

Revista portuguesa de cardiologia : orgao oficial da Sociedade Portuguesa de Cardiologia = Portuguese journal of cardiology : an official journal of the Portuguese Society of Cardiology, 2001
This paper try to give a general overview of the main areas of DTI clinical application, its main technical limitations, new directions still under investigation and some potential future developments of this emerging imaging technique. In this review article we pretend to discuss the main aspects of the new DTI method, its present "state of the art ...

Intracardiac Shunts and Role of Tissue Doppler Imaging in Diagnosis and Discrimination [PDF]

Journal of Tehran University Heart Center, 2008
Background: We sought to assess right ventricular (RV) systolic and diastolic functions via tissue Doppler imaging (TDI) in order to discriminate right-to-left (bidirectional) from left-to-right intracardiac shunts.
