There are a lot of documents that we don’t need to keep, but when it comes to medical records, we need to make sure that these are held on to for a specific amount of time. In this article, Rads Document Storage take a look at how long you need to keep medical records for, and the best way to do this. What are medical records? Medical records can cover a wide number of things. Not only ...
MRI is one of the safest and most descriptive diagnostic tools ever invented. Unlike CT or conventional X-rays, there is no carcinogenic (ionizing) radiation involved. There are no known biological risks associated with exposure to magnetic fields of the strength used in clinical MRI’s. And though there have been compatibility issues with medical devices, such as pacemakers, the clinical ...
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 ...
The use of computer vision in radiology may have advantages for both patients and medical facilities. However, some worry that machine learning (ML) may one day replace doctors because it can outperform them. The desire for increased efficiency and efficacy in clinical care has been the primary motivating reason behind the development of AI in medical imaging. Recent technological developments, ...
What is Lumbar Spinal Stenosis? Lumbar spinal stenosis, or LSS, is a common condition in which the lower spinal canal narrows and compresses the nerves in the lower back. Lumbar spinal stenosis is generally caused by aging and natural wear and tear on the spine. With lumbar spinal stenosis, thickened ligament, overgrowth of bone, and/or bulging discs in the lower back put pressure on the ...
Depression and the vagus nerve Depression affects millions of people worldwide and constitutes a leading cause of disability. Although pharmacological interventions are available, many of them produce suboptimal outcomes due to high non-responsive rates or intolerable side effects. It has been estimated that between 20 to 40 per cent of patients either failed to respond to conventional ...
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 ...
Despite breast cancer being the second most common cancer for women in the US, progress in the breast imaging space has been stagnant over the last few decades. This is evident in the countless women who are still misdiagnosed – either receiving a false positive or getting diagnosed in the later stages of the disease. Why Early Detection is Important According to the National Breast ...
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 is widely used in research on brain structures and functions. How MRI Works MRI scanning machines vary in size, shape, and degree of openness but the typical MRI machine resembles a tube (encompassing a very large magnet) with a table in the middle, which enables the patient to lie down and slide into the ...
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 ...
We explore the pivotal role medical UPS systems play in an increasingly digitalised healthcare sector. Clean and continuous power requirements in medical applications have an extensive impact on healthcare in so many ways. Electricity powers critical care equipment like scanners and heart monitors. It keeps the IT and comms infrastructure needed to manage patient records, arrange appointments ...
Who bears formal responsibility for the serious MRI accident at Sunderby Hospital in Luleå, Swedish Lapland? This complex question appears to lie at the heart of the investigation that's still going on, and the answer may well set a legal precedent, according to experts. The accident took place on 23 October, and it led to injuries to a specialist nurse, along with the mobile MRI scanner ...
The cornerstone of a safe MRI workplace is repeated and updated MRI safety training and awareness. The number of MRI scanners is increasing, and scanners are also moving toward higher field strengths, both in private practice and at hospitals and institutions all over the world. Consequently, there is a large and increasing crowd of radiology staff and others who need MRI safety education to keep ...
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 ...
In the summer of 2001, the radiology world was shocked to learn of an accident at Westchester Medical Center in New York state in which 6-year-old Michael Colombini was killed while being prepared for an MRI exam. Sedated and positioned in the scanner, the child's oxygen saturation levels began dropping quickly. After the piped-in oxygen serving the MRI scanner room malfunctioned, the ...
Abstract The purpose of this article is to educate medical professionals on the safety concerns that arise when a healthcare organizations converts from a 1.5 Tesla MRI scanner to a 3 Tesla MRI scanner. This article explains the differences between the two systems and the safety concerns associated. One of the obstacles that an MRI Technologist endures is that some implanted materials that have ...
