16. Cell response to imaging contrast agents suggested for atherosclerotic plaque imaging
Abstract : Oxysterols are the major cytotoxic components of oxidized low-density lipoprotein (OxLDL) that accumulate in atherosclerotic plaques. Their uptake by macrophages ensue foam cell formation, atherogenesis and plaque progression. READ MORE

17. Are gadolinium contrast media really less nephrotoxic than iodine agents in radiographic examinations? A comparison in relation to their ability to attenuate x-rays in a pig model
Abstract : Purpose: To confront the statement that gadolinium contrast media (Gd-CM) are less nephrotoxic than iodine contrast media (I-CM) when used in x-ray angiographic and computed tomographic (CT) examinations. Methods: I) For CT measurements (mean density in Hounsfield numbers) 20-mL syringes filled with I- and Gd-CM at 0.01, 0.02, 0. READ MORE

19. On Nonlinear Acoustics in Contrast Echocardiography
Abstract : Ultrasound is one of the most commonly used noninvasive medical imaging techniques. Ultrasound contrast agents (UCA), consisting of encapsulated gas-filled microbubbles, have shown to increase the diagnostic precision in selected low echogenic patients. READ MORE

20. One-click away from higher contrast : Improvements to peripheral clearance for same-day immunoPET in Alzheimer’s disease
Abstract : The brain is a challenging target for antibody-based positron emission tomography (immunoPET) to image amyloid-beta (Aβ). Antibodies detect pathology with high sensitivity, but due to their size and biological half-life, they cause a high background radiation, if radiolabelled. READ MORE
