RADIUS - Developing new and improved MRI imaging protocols - Case Study
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 ...

Imaging Review Tips for Advance Practice Providers
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 ...

The Zap-X Radiosurgical System in the Treatmentof Intracranial Tumors
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 ...

Postoperative Spinal Instability at L3-4 Revealed by Upright Weight-Bearing MRI - Case Study
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 ...

Neuroscientific evidence: a criminal justice dream, or an adversarial nightmare?
This exploratory paper seeks to examine the use of neuroscientific evidence in the criminal trial process. Such evidence is not currently employed in the pre–trial or trial stages in England and Wales. However, the first use of polygraph lie detectors during the pre–charge process has recently been trailed by Hertfordshire Police. More advanced techniques such as the BEOS test and the use of fMRI ...

Ensuring the safe use of MRI scanners
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 ...

Do you really have to sacrifice MRI image quality for speed?
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 ...

Nanotechnology as a basis for the vascular treatment of atherosclerosis
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 ...

The effects of antidepressants appear to be rapid and at environmentally relevant concentrations
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 ...

Innovative technology of engineering magnetic DNA nanoparticles for gene therapy
The present research study is a novel innovation materials technology to engineer magnetic DNA nanoparticles for gene therapy and to enhance the localisation and gene expression of a plasmid DNA via magnetic DNA nanoparticles. Spermine (Sm) was chemically introduced to the hydroxyl groups of dextran, a polysaccharide, to obtain cationised dextran (dextran-Sm). When Fe2+ solution was added to the ...

APBI with VeraForm & SAVI Brachytherapy: Marking for the Unpredictable
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., ...

New Method to Produce Ring-Opening Metathesis Polymers with Facile Degradability
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 ...

Image is Everything: MRI and Helium Safety
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 ...

Freehand Transperineal Biopsy
“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 ...

Understanding Pediatric Cardiomyopathy: Causes, Symptoms and Treatment Options
Up to 5,000 American infants and children are diagnosed with pediatric cardiomyopathy each year. Learn more about this rare but potentially serious condition. Cardiomyopathy, which is a general term for diseases of the heart muscle, is relatively rare in children, affecting only about 12 out of every 1 million Americans under the age of 18. Among the approximately 1,000 to 5,000 new cases ...
