Dendrimers are highly branched polymers with a three-dimensional structure. They are characterized by expansive functional groups on their surface, which can be tailored to interact with specific molecules or to be used in a variety of applications. Dendrimers have attracted much attention in drug delivery, imaging, and materials science due to their unique structure, high monodispersity, and ...
To understand the significance of the SpinTech MRI STAGE software platform, it helps to begin by asking a question: Given that MRI is an incredibly powerful diagnostic tool for neurological diseases like Alzheimer’s, dementia, Parkinson’s and multiple sclerosis (MS), why have radiologists and neurologists had to choose between conducting faster MRI exams and obtaining higher-quality ...
According to our Advanced Practice Provider (APP) Advisory Board, imaging review, a key aspect of mild® patient candidate identification, is often not included in initial schooling. To help APPs learn the basics of image review, become more familiar with identifying anatomical landmarks, and understand how to confirm if a patient is a candidate for the mild® Procedure, we asked James ...

This study aims at developing new and improved MRI imaging protocols in order to obtain better quality images and improved/reduced scan time. We will also assess whether multi-parametric MRI imaging of multiple organs gives the same results when it is repeated on the same person after a period of time, and when it is performed on the same person in different MRI scanners. We hope that, by running ...
“Freehand transperineal biopsy” seems to be the latest buzzword in the urology world, and for good reason. Compared to transrectal, transperineal is proven to be the cleaner and ultimately safer approach for prostate biopsies. The support for transperineal is growing, as mounting evidence continues to debunk previous misconceptions of tolerability, feasibility and accuracy. We ...
Guidance for Industry and Food and Drug Administration Staff Introduction This guidance document provides Food and Drug Administration’s (FDA’s or the Agency’s) recommendations on testing to assess the safety and compatibility of medical devices in the Magnetic Resonance (MR) Environment and the recommended format for Magnetic Resonance Imaging (MRI) Safety Information in ...
BACKGROUND AND IMPORTANCE:The Zap-X system (Zap Surgical Systems Inc, SanCarlos, California) is a radically new surgical robot designed for brain and head and neckradiosurgery. It represents the first new dedicated brain stereotactic radiosurgery platformin almost half a century optimizing the goals of safety, speed, and accuracy. The Zap-Xsystem was used in a required Chinese National Medical ...
The patient was scanned in the FONAR Upright MRI in early 2002, one year after her spinal fusion. Both Upright and recumbent scans were performed on her in the multi-position FONAR Upright MRI. The recumbent MRI (left image) exhibited only a normal lumbar lordotic curve and a modest bulge of the L3-4 intervertebral disc, consistent with her prior recumbent MRI scan on a conventional MRI. The ...
MRI Magnetic resonance imaging (MRI) is a diagnostic procedure that uses a combination of a very large magnet, radio waves, and a computer to produce detailed, cross-sectional, and three-dimensional images of organs and structures within the body. An MRI scan is a valuable diagnostic tool that can show injuries or other anomalies that cannot be seen in a CT scan or X-ray. For instance, soft ...
Hospitals throughout the world, working towards improving the lives and outcomes for cancer sufferers, are using MRI (magnetic resonance imaging) scanners to diagnose and stage cancer in patients. Whilst the magnetic fields and radio waves used by MRI scanners pose no risk to humans, scanners’ cooling system potentially do, and careful installation and maintenance is essential to ensure ...
Exact Imaging is a leading developer of ultra-high-resolution micro-ultrasound diagnostic technologies Micro-ultrasound ExactVu™ is the only ultrasound-based imaging tool with published data demonstrating prostate cancer diagnostic capabilities similar to MRI Combination of Exact Imaging’s micro-ultrasound and EDAP’s Focal One® represents the most complete offering for ...
Our Medical Director of the Oncology Breast Program, Dr. Beth DuPree, was first in the U.S. to adopt VeraForm, a continuous, radiopaque 3D tissue marker. Within months, its utility led to quick integration into our program’s standard daily practice. Like all centers today, patient satisfaction is a focal point and to date, we have seen no complications or toxicities by any criteria (e.g., ...
A team of chemists at MIT has formulated a method to produce polymers that can disintegrate more readily in the body as well as in the environment. A new type of polymer designed by MIT chemists incorporates a special monomer (yellow) that helps the polymers to break down more easily under certain conditions. (Image credit: Demin Liu) A chemical reaction known as ring-opening metathesis ...
Magnetic resonance imaging (MRI) is a frequently used diagnostic imaging modality that may be an alternative to other types of radiologic imaging (e.g., computerized tomography, nuclear medicine imaging). It can detect soft tissue characteristics (e.g., inflammation), and because magnetic resonance (MR) uses a magnetic field and radio waves to produce images, it does not expose patients to ...
The effects of antidepressants on wildlife are currently raising some concern due to an increased number of publications indicating biological effects at environmentally relevant concentrations (<100ng/L). These results have been met with some scepticism due to the higher concentrations required to detect effects in some species and the perceived slowness to therapeutic effects recorded in ...
Helium is well known as Helium that makes balloons and airships float and in its liquid form, Helium is used in a variety of applications including cooling for magnets in Magnetic Resonance Imaging (MRI) scanners, cooling infrared detectors, and as a superconductor coolant in the large hadron collider at CERN. Helium is distilled from natural gas deposits that have collected in the presence of ...
2013 Trend Report: Magnetic Resonance Imaging Magnetic resonance imaging, or MRI, is a powerful diagnostic tool for today's medical practitioners. New advances in scanner technology are increasing the breadth of MRI's applications at a rapid pace, and the number of scanning suites has exploded in the past decade. Due to the immense technical complexity of MRI systems, these suites can be ...
It is now accepted that during the early stages of development of coronary and carotid atherosclerotic plaques, activation of vasa vasorum (VV) at specific sites in the adventitia initiates their proliferation or 'angiogenesis', and migration through the media into the intima of unstable developing lesions. Plaques regions containing these immature vessels tend to exhibit increased inflammation ...
Magnetic resonance imaging (MRI) was used to spatially resolve the structure, water diffusion, and copper transport of a phototrophic biofilm and its fate. MRI was able to resolve considerable structural heterogeneity, ranging from classical laminations 500 µm thick to structures with no apparent ordering. Pulsed-field gradient (PFG) analysis spatially resolved water diffusion coefficients which ...
