Introduction Quantitative BOLD (Blood Oxygen Level Dependent) has been proposed to map brain oxygenation levels using MRI [1]. This approach yields tissular SO2 (oxygen saturation) estimates, i.e. a mean SO2 across the microvascular network in the MRI voxel. To improve the accuracy and the spatial resolution of SO2MR maps, an approach which combines a steady-state Blood Volume fraction (BVf) me...

In perioperative medicine, hemodynamic management aims at an optimization of perfusion pressure and oxygen delivery in order to maintain or restore adequate cellular metabolism (1). To optimize cardiopulmonary function, hemodynamic management triggers the administration of fluids and vasoactive agents according to predefined target values of hemodynamic variables. This is often referred to as “...

where PV is the volume of blood pumped, that is given by the difference between the end-diastolic volume (EDV) and the end-systolic volume (ESV). Cardiac ejection fraction is a relevant parameter because it is highly correlated to the functional status of the heart. To determine the EF, different non-invasive techniques can be used, like echocardiography, cardiac magnetic resonance and computed...

The innovative non-invasive intracranial volume wave monitor has been developed in Telematics Scientific Laboratory of Kaunas University of Technology (Lithuania). It is based on the measurement of the human brain parenchyma acoustic properties (ultrasound speed and attenuation) using time-of-flight technique [1,2] and it is capable of measuring different types of intracranial volume wave (slow...

Introduction: The great use of electrical appliances in different life applications is one of the most obvious concerns because of its possible health drawbacks. These investigation reports results of electromagnetic field effect emitted from mobile phones on some biophysical parameters of human blood belonging to blood groups A, B, AB & O collected from the normal persons. The parameters obser...
