BACKGROUND Micro-CT imaging of liver disease in mice relies on high soft tissue contrast to detect small lesions like liver metastases. Purpose of this study was to characterize the localization and time course of contrast enhancement of a nanoparticular alkaline earth metal-based contrast agent (VISCOVER ExiTron nano) developed for small animal liver CT imaging. METHODOLOGY ExiTron nano 6000...
background: use of contrast agents (cas) during ct simulation for treatment planing system leads to changes in electron density. in this study we aimed to investigate the effect on calculated dose of various concentrations of cas on treatment planing systems in different dose calculation algorithms. materials and methods: contrast agent (0.769 mg/ml iopromid) - water mixtures at concentration...
Optoacoustic imaging is a rapidly expanding field for the diagnosis, characterization, and treatment evaluation of cancer. However, the availability of tumor specific exogenous contrast agents is still limited. Here, we report on a small targeted contrast agent for optoacoustic imaging using a black hole quencher® (BHQ) dye. The sonophore BHQ-1 exhibited strong, concentration-dependent, optoaco...
slice images of Gd-DTPA, Gd-DOTACAT and 10% BSA at 37oC at 9.4T. Figure 2. Relaxation rate (R1 = 1/T1) as a function of concentration. Gd-DOTACAT has a greater relaxivity 6.9 (mM s) than clinically used Gd-DTPA (Magnevist®) of 3.2 (mM s). Figure 3. Signal intensity plots from 3 regions of interest: brain tissue, cerebral and non-cerebral blood vessels. There was an increase in signal intensity ...
