A community portal about Magnetic resonance imaging with blogs, videos, and photos. According to Wikipedia.org: Magnetic Resonance Imaging , formerly referred to as Magnetic Resonance Tomography or, in chemistry, Nuclear Magnetic Resonance , is a method used to visualize the inside of living organisms as well as to detect the composition of geological structures. It is primarily used to demonstrate pathological or other physiological alterations of living tissues and is a commonly used form of medical imaging. MRI has also found many novel applications outside of the medical and biological fields such as rock permeability to hydrocarbons and certain non-destructive testing methods such as produce and timber quality characterization. The scanners used in medicine cost approximately $1 million USD per Tesla for each unit, with several hundred thousand dollars per year for maintenance. A man from Fraserburgh, Scotland, with terminal liver cancer become the first patient in the world to receive an MRI body scan in Aberdeen, U.K.

Nursing Home Patients Continue To Receive Drugs Associated With Known Dangers

Written by goose575 on
Through no fault of their own, many nursing home patients continue to receive medications known to potentially cause serious injury or death.  Many of these situations involve claims for damage against the drug manufacturers themselves.  In other cases, the prescribing physician may be partially responsible for failing to monitor the patient. MRI Danger: Gadolinium Liquid May Cause Severe Reactions Such As Nephrogenic Systemic Fibrosis In 1988 the FDA approved the use of Gadolinium for use as a contrast agent in MRI's. Contrast agents help in enhancing the clarity of MRI images. Gadolinium bonds with damaged or diseased tissues giving doctors a much clearer picture ... Read Full Story

GE Using UK Libel Laws to Shield Omniscan from Criticism, Doctor Claims

Written by Cynthia111 on
Date Published: Monday, December 21st, 2009 General Electric has been accused of trying to stifle criticism of its Omniscan gadolinium contrast dye by a Danish radiologist who warned it was associated with nephrogenic systemic fibrosis (NSF) in 2007. According to an article in The Guardian, Henrik Thomsen claims a subsidiary of General Electric has sued him under the United Kingdom’s tough – some would say draconian – libel laws to keep him quiet about Omniscan’s alleged health risks. Gadolinium contrast dyes are used to enhance images during MRI, and sometimes MRA, procedures. NSF is a rare, debilitating and often fatal disease that appears to ... Read Full Story

U.S. panel sees higher skin risk with some MRI drugs

GAITHERSBURG, Maryland (Reuters) - U.S. advisers felt MRI imaging drugs from GE Healthcare and Covidien appear to carry a higher risk of a serious skin disease in some patients than similar products, a Food and Drug Administration official said on Tuesday. The "preponderance of opinion" on the panel was GE's Omniscan and Covidien's Optimark should carry a warning saying they should not be used in patients with severe kidney disease, Dr. Dwaine Rieves, the FDA's head of medical imaging and hematology products, told reporters after a panel debated the drugs' risks. The FDA will consider the advisers' input. The agency did not ask the ... Read Full Story

Greater risks seen with certain imaging agents: FDA

WASHINGTON (Reuters) - A U.S. Food and Drug Administration review found the risk of a serious skin disorder is greater with MRI imaging contrast agents made by GE Healthcare, Bayer AG's and Covidien, according to an agency memo released on Wednesday. The review recommended that labels for the products -- GE Healthcare's Omniscan, Bayer AG's Magnevist and Covidien's Optimark -- recognize their greater risk for the disorder over other agents, the memo said. FDA officials released the memo ahead of a December 8 meeting to discuss the risks with all gadolinium-based contrast agents, which were ordered in 2007 to carry a "black-box" warning about ...

MRI...class-action! Manufacturer Bayer AG rushes into settlement talks! No cure for Nephrogenic Systemic Fibrosis!

Written by julianayrs on
If you recall, I reported a few months ago that there was a pending class-action suit against the manufacturers of Gadolinium-based contrast agents used in the MRI scan process. Post:  03/15/2009 http://ijulian.blogspot.com/2009/03/mripending-class-action-lawsuit.html According to my sources, Bayer AG (one of the product makers of the dangerous agent that is ingested to facilitate a proper reading of an MRI or MRA) has confirmed that they have reached agreements in principle with several of the plaintiffs in the U.S. to settle without admission of liability. In their causes of action for the class-action suit, the plaintiffs alleged that individuals who ingested the contrast agent under the supervision of ... Read Full Story

New MRI safety risk for patients with pacemakers identified
Researchers have found that certain cardiac pacemakers may inadequately stimulate a patient's heart while undergoing a magnetic resonance imaging (MRI) scan due to the magnetic pulses mixing with the electronic pulses from the pacemaker. This inadequate stimulation is potentially dangerous for the patient undergoing the MRI scan, according to new research.
