Perfusion assessment via local remote photoplethysmography (rPPG) [PDF]
2022 IEEE/CVF Conference on Computer Vision and Pattern
Recognition Workshops (CVPRW), 2022 This paper presents an approach to assess the perfusion of visible human tissue from RGB video files. We propose metrics derived from remote photoplethysmography (rPPG) signals to detect whether a tissue is adequately supplied with blood. The perfusion analysis is done in three different scales, offering a flexible approach for different applications ...

The Journal of ExtraCorporeal Technology, 2023 Background: The advantages of mechanical assistance during ventricular tachycardia (VT) ablation have not been clinically demonstrated. We propose and discuss a technique, set up by us, that makes use of minimally invasive extra-corporeal circulation ...

Perfused and Nonperfused Microaneurysms Identified and Characterized by Structural and Angiographic OCT [PDF]
Ophthalmology Retina 2023, 2023 Purpose: Microaneurysms (MAs) have distinct, oval-shaped, hyperreflective walls on structural OCT, and inconsistent flow signal in the lumen with OCT angiography (OCTA). Their relationship to regional macular edema in diabetic retinopathy (DR) has not been quantitatively explored.

Use of sugammadex in patients with neuromuscular disorders: a systematic review of case reports
BMC Anesthesiology, 2019 Background Sugammadex is a modified gamma-cyclodextrin that acts by selectively encapsulating free amino-steroidal neuromuscular relaxants. Several case reports have been published on the use of sugammadex in patients with neuromuscular disorders that ...

Quantitative perfusion and water transport time model from multi b-value diffusion magnetic resonance imaging validated against neutron capture microspheres [PDF]
, 2023 Intravoxel Incoherent Motion (IVIM) is a non-contrast magnetic resonance imaging diffusion-based scan that uses a multitude of b-values to measure various speeds of molecular perfusion and diffusion, sidestepping inaccuracy of arterial input functions or bolus kinetics in quantitative imaging. We test a new method of IVIM quantification and compare our

The perfused swine uterus model: long-term perfusion [PDF]
Reproductive Biology and Endocrinology, 2012 Abstract Background It has previously been shown that the viability of swine uteri can be maintained within the physiological range in an open perfusion model for up to 8 hours. The aim of this study was to assess medium- to long-term perfusion of swine uteri using a modified Krebs–Ringer bicarbonate buffer solution ...
