both an MRI contrast agent and an FI contrast agent, the MRI/FI contrast agent being suitable as a contrast agent due to the small average diameter thereof, and suitable as an MRI contrast agent due to the high T2 spin relaxation coefficient (r2) thereof; and a preparation method therefor...
To optimize in advance an amount of a desired parameter incorporated in a pulse sequence performed by an imaging scan, a preparation scan is adopted. A preparation scan performing element (1-8T,8R) performs the preparation scan with the inversion time TI changed every preparatory image, so tha...
99Tcm,and its biodistribution was not changed on the whole after labeled.The study indicated that DTPA as a bifunctional chelator may be linked with 99Tcm and Gd.As a type of new multimodality imaging agents with higher targeting characteristics,it could be applied both in SPECT and MRI scan....

If you have had aCT or MRI scanrecently with contrast, then you need to take the test after a period of at least 7 days. You are advised to carry your old medical reports or treatment history (if you are one any). You must discuss with your doctor if you have prosthetics like heart...
The protocol enhances the contrast when using X-ray imaging, while preventing sample motion during the scan, even with different sample orientations. Bubbles trapped during mounting and those formed during scanning (in the case of synchrotron X-ray imaging) are mitigated by multiple degassing steps...
Such a data set would be massive in terms of scan time and storage (up to 70 GB before reconstruction), in addition to the computing power and time needed to reconstruct and render each of the 3D files individually. To improve the μCT process for smaller specimens without sacrificing image...

they were originally designed for contrast-enhanced ultrasound (CEUS) imaging, as they are purely intravascular, highly echogenic and allow excellent macro and micro-vasculature visualization7,8. MBs represent a key component of US-mediated BBB opening, as they act as intravascular “cavitation nuclei...
