1. Contrast-enhanced ultrasound in children
Abstract : Background: Contrast-enhanced ultrasound (CEUS) is a diagnostic tool that is used for many applications in adults. Many of these applications are considered “off-label” use but still play an important role in diagnostic imaging. READ MORE

2. Contributions to quantitative dynamic contrast-enhanced MRI
Abstract : Background: Dynamic contrast-enhanced MRI (DCE-MRI) has the potential to produce images of physiological quantities such as blood flow, blood vessel volume fraction, and blood vessel permeability. Such information is highly valuable, e.g., in oncology. READ MORE

3. Contrast-Enhanced Magnetic Resonance Angiography - Development and optimization of techniques for paramagnetic and hyperpolarized contrast media
Abstract : Contrast-enhanced magnetic resonance angiography (CE-MRA) is a diagnostic method for imaging of vascular structures based on nuclear magnetic resonance. Vascular enhancement is achieved by injection of a contrast medium (CM). READ MORE

4. Contrast enhanced ultrasound (CEUS) in breast tumors
Abstract : Contrast-enhanced ultrasound or CEUS is a combination of the pharmacokinetics of contrast agents (or microbubbles-based ultrasound contrast agents), the signal processing of these agents and the contrast-specific imaging modality. One of the main objectives of this method is to gather vascular information (from large vessels to capillaries) in different organs or tumors by increasing the signal intensity from blood. READ MORE

5. Contrast enhanced transrectal ultrasound of the prostate : An experimental and clinical study
Abstract : The purpose of this thesis was to evaluate the diagnostic potential of a new ultrasound contrast agent,SonazoidTM, intended for use in patients with suspicion of prostate cancer.The sonographic appearance of normal prostatic vascularity in dogs was evaluated before and after injection of Sonazoid,using different Doppler flow detection modes.
