In addition, MRI machines may be problematic for people with claustrophobia. To minimize this risk, imaging centers increasingly use open MRI equipment. If you areundergoing an MRItell your healthcare provider and the MRI technologist if you have any metal implants, claustrophobia, allergies, or ki...
MRI is now commonly used for a variety of applications such as diagnosis of ligament damage,42 detection and diagnosis of brain tumors,43 detection of kidney stones,44 and more recently functional brain mapping.45 Despite having superior spatial resolution (sub-millimeter) over X-ray, MRI ...
Iron oxide nanoparticles (IONPs) have emerged as a promising alternative to conventional contrast agents (CAs) for magnetic resonance imaging (MRI). They have been extensively investigated as CAs due to their high biocompatibility and excellent magnetic properties. Furthermore, the ease of functionaliza...
Newer dyes that permit visualization of the bile channels without concentration by the gallbladder are administered intravenously to determine or rule out the presence of intermittent obstruction of the bile ducts or recurrent biliary disease after biliary surgery. ...
A contrast scan is an extremely valuable tool for diagnosing diseases, and assessing internal damage and other abnormalities. While there is a possibility of reactions to the contrast agent, these are rare, and undergoing the test is generally preferable to leaving a disease or condition untreated....
As a soluble contrast agent, iodine is generally harmless and, as a result, most intravenous contrast dyes are iodine-based. Contrast-enhanced ultrasound uses micro-bubbles filled with trace amounts of nitrogen or fluorocarbons as contrast agents which are administered intravenously. The bubbles ...
A patent has been filed and the technology licensed to CRI Inc., of Woburn, Mass., which offers multispectral imaging and analysis tools based on various emission wavelengths of dyes. Plans call for a product launch within the next few months, and Hillman is working with the company on this...
Dual modal imaging combining MRI/fluorescent probes can over- come the limitations of each modality29. Researchers usually prefer to conjunct fluorescent organic dyes with already prepared MRI CAs to develop such dual probes. For example, such probes have been syn- thesized by combining mesoporous ...
However, a fundamental limitation of light-based microscope imaging techniques employing dyes or fluorochromes is that they produce toxic photobleaching byproducts and are limited by light scattering to those cells within 100 m of the surface. Magnetic resonance imaging (MRI) of biological structures ...
