Contrast agents in dynamic contrast-enhanced magnetic resonance imaging
Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is a noninvasive method to assess angiogenesis, which is widely used in clinical applications including diagnosis, monitoring therapy response and prognosis estimation in cancer patients. Contrast agents play a crucial role in DCE-MRI and should be carefully selected in order to improve accuracy in DCE-MRI examination. Over the past...
متن کاملEffects of paramagnetic contrast agents on the gallbladder volume.
PURPOSE Iodinated contrast agents lead to contraction of the gallbladder. The purpose of this prospective study was to investigate whether the paramagnetic contrast agents used for magnetic resonance imaging (MRI) cause volume changes in gallbladder or not. MATERIALS AND METHODS The gallbladder volume changes were evaluated by ultrasound just before and 15 minutes after the imaging procedure ...
متن کاملEnhanced targeting of ultrasound contrast agents using acoustic radiation force.
Contrast-enhanced ultrasound has shown significant promise as a molecular imaging modality. However, one potential drawback is the difficulty that ultrasound contrast agents (UCA) may have in achieving adhesion to target molecules on the vascular endothelium. Microbubble UCA exhibit a lateral migration toward the vessel axis in laminar flow, preventing UCA contact with the endothelium. In the c...

متن کاملAlignment of Contrast Enhanced Medical Images
The re-alignment of series of medical images in which there are multiple contrast variations is difficult. The reason for this is that the popular measures of image similarity used to drive the alignment procedure do not separate the influence of intensity variation due to image feature motion and intensity variation due to feature enhancement. In particular, the appearance of new structure pos...
