Imaging Predictors of Silent Brain Lesions: Correlating Carotid Plaque Features on Ultrasound and CT in an Observational Study

Perica Mutavdžić, Tijana Koković, Ivan Tomić, David Matejević et autres

Background/Objectives: Risk stratification in asymptomatic carotid stenosis has traditionally relied on the degree of luminal narrowing; however, plaque vulnerability may better predict cerebrovascular events. Ipsilateral silent brain lesions (SBLs) are considered surrogate markers of stroke risk. This study aimed to identify carotid …

Haemodynamics of femoropopliteal bypass surgery using finite element analysis method

Dragan Sekulić, Aleksandar Tomić, Danko Milašinović, Dalibor Nikolić et autres

Objective. Femoropopliteal bypass is indicated in the advanced stage of peripheral arterial occlusive disease. The indications for surgical treatment are determined on the basis of a clinical exam, "ankle-brachial index" and angiographic findings. Using the finite element analysis method, three-dimensional models can …

Microstructural computational modelling of soft tissues

Aleksandar Tomić, Alfio Grillo, Salvatore Federico

In this work we numerically implement a previously developed large deformation model for porous fibre-reinforced materials with statistically oriented fibres, including the effect of the presence of the fibres on both the elastic properties and the permeability. The model is microstructural, based …

Remodelling in statistically oriented fibre-reinforced materials and biological tissues

Alfio Grillo, Gabriel Wittum, Aleksandar Tomić, Salvatore Federico

We present a mathematical model of structural reorganisation in a fibre-reinforced composite material in which the fibres are oriented statistically, i.e. obey a probability distribution of orientation. Such a composite material exemplifies a biological tissue (e.g. articular cartilage or a blood vessel) …
