Quantitative contrast-enhanced mammography, based on a dual-energy approach, aims to extract quantitative and temporal information of the tumour enhancement after administration of iodinated vascular contrast media. Simulations using analytical expressions and optimization of critical parameters essential for the development of quantitative contrast-enhanced mammography are presented. The proce...

background: l-carnitine may prevent the incidence of aki by its antioxidant effects and improving circulation in ischemic conditions. the goal of this trial was to evaluate the impact of l-carnitine on contrast-induced nephropathy in patients undergoing elective pci. methods: totally, the patients were randomly allocated to 2 groups. the treatment group received 1 g of l-carnitine orally 3 time...

the advent of dual-modality pet/ct imaging has revolutionized the practice of clinical oncology, cardiology and neurology by improving lesions localization and the possibility of accurate quantitative analysis. in addition, the use of ct images for ct-based attenuation correction (ctac) allows to decrease the overall scanning time and to create a noise-free attenuation map (μmap). the near simu...
