MRI shows traumatic brain lesions not shown on CT

 - Brain injury

 

MRI indicated brain contusions and axonal injury independently associated with poorer three-month outcome after mild traumatic brain injury (MTBI), according to a study published online Dec. 7, 2012, in Annals of Neurology .

 

Yuh and colleagues reported that MRI identified many more acute traumatic intracranial lesions than CT. A total of 27 percent of participants had abnormal CT results. However, among the 98 patients without CT evidence of skull fracture or acute intracranial injury, 28 percent had abnormal MRI results. These findings included 23 patients with hemorrhagic axonal injury, three patients with brain contusions and four patients with extra-axial hematomas.

Economy causing more MRI accidents?

Insurers, the organizations that pay for the vast majority of MRI exams in the US, have been incrementally cutting the prices that they’ll pay hospitals and imaging centers for MRI studies. To a degree, this has been in response to ever-growing MRI scan volumes, which have lead to some economies of scale. A few years ago, Medicare / Medicaid switched from taking incremental nibbles off of the reimbursement rate, to lopping off a huge chunk with the budgetary equivalent of a machete, called the Deficit Reduction Act (DRA). Many commercial insurers followed suit.

The accumulated reimbursement cuts from the whole cadre of insurers has taken years following the initial enactment of the DRA to reach its full effect, just in time for the bottom to drop out of the broader economy. Now MRI providers are not only getting paid less for each exam, with many patients having to fork-over a 20% copay for the cost of their MRI exam, the number of patients walking in the door has also dropped.

A trend that began with the enactment of the DRA a few years ago may actually be building momentum, namely cutting staff, or cutting staff qualifications, to reduce the operating expenses of an MRI operation. Source

 

These reductions may be the worst thing for any hospital or outpatient center. Your greatest asset is The MRI technologist. The technologist understands MRI Safety at a level unparalleled to any one else in the diagnostic imaging environment. As the level of training decreases of staff the level of MRI safety accidents will continue to rise inversely proportionally. This is exactly why there has been a 277% rise in reported accidents.

This may seem a little over-simplified evaluation of a very complicated matter. However, the economy does correlate to the dramatic rise in MRI safety accidents. I can only put the pieces together. If cut backs are hurting health care at the patient level, where safety is concerned it is time to step in and make some drastic changes. Please let me know how you feel about this……

 

 

Please regulate MR safety practices

 

 

The knowledge base for safety in the MRI suite suffers from a number of profound disparities. The types of risks and potential accidents for persons in the MR suite are well known to clinical and technical MR personnel, but the rates at which these accidents occur on a national basis are obscured by profound under-reporting. And though many experienced MR staffers understand the risks, it is likely that the incidental personnel—such as housekeeping, engineering, transport—who may regularly serve the area know little of the breadth of risks to which they may be exposed (or to which they may be exposing others). 2007, however, has already seen the introduction of new tools and standards, which will help improve safety in the MR suite and also may work to narrow the dangerous gaps in our knowledge and promote enhanced standards of care.

Chief among these resources is the new American College of Radiology (ACR) Guidance Document for Safe MR Practices: 2007, which supersedes the two previous ACR safety documents published in 2002 and 2004 under the title of the White Paper on MR Safety. The new document was recently published in the American Journal of Roentgenology (AJR), though, through a special arrangement, the text has been circulating in electronic format since early this spring. Because of the importance of this document and the pressing safety issues it addressed, the ACR and AJRagreed to provide the document on both organizations’ web sites for free download as soon as the final manuscript was accepted for publication.

The arrival of this new document came not a moment too soon as the FDA’s Manufacturer and User Facility Device Experience (MAUDE) Database recorded a 140% increase in reported MRI accidents for the 12-month period ending in mid 2006. Though Emanuel Kanal, MD, chair of the ACR’s MR Safety Committee, and other MR safety experts believe that accidents reported to the FDA represent less than 10% of the actual number of incidents that occur (some, including John Gosbee, MD, formerly of the VA’s National Center for Patient Safety, have speculated that reporting of MRI accidents is near 1%), this recent dramatic increase is suspected to be the result of compounding increases in risk more than a significant shift in reporting.

Factors such as increasing magnet strength, greater utilization for emergent/trauma cases, wider patient dependence on medical devices or implants that may be contraindicated for MR exams, larger numbers of sedation/general anesthesia patients, and interventional applications from image-guided biopsies to intraoperative imaging are all perceived to ratchet up the opportunities for mishaps.

These increasing risk factors, perhaps statistically insignificant individually, compound in many facilities, and, when multiplied by the estimated 20,000,000 MRI exams performed annually in the United States alone, can be the source for dramatic increases in rates of accidents. If all of these factors combined to create only 1/100th of 1% likelihood of an MR accident resulting in a serious injury, statistics would suggest that we would see an increase of 2,000 serious MR injuries, some potentially even fatalities, in any given year. For a modality with an unparalleled safety record, this sort of accident frequency would be abhorrent, particularly given the fact that the vast majority of MR accidents are completely avoidable.

At the present time, there are no specific MR safety standards at the site level that are a part of payor credentialing, national provider accreditation programs, or even state or federal regulations. The absence of professional regulations, however, is on the brink of changing.

MR safety issues are currently under scrutiny by groups as varied as the American Society of Anesthesiologists, the committee that writes the building code for hospitals and health care facilities, the VA health care system, The Joint Commission, and the ACR’s Committee on MR Accreditation. These examples highlight the disconnects that have plagued concerted efforts to standardize MR safety issues, namely, the absence of unified professional standards. The ACR’s MR accreditation program, however, has worked to bridge this gap and references ACR’s MR safety guidance as a recommendation for those seeking accreditation. But soon sites seeking MR accreditation from the ACR may face new questions and scrutiny about safety provisions as a part of that process. Source

Although MRI can provide important diagnostic information, medical practitioners and patients should be aware that there are several hazards associated with MRI.

The ACR created a multidisciplinary blue ribbon panel to address critical issues in MR safety. Initially published in in theAmerican Journal of Roentgenology in June 2002, updated in May 2004, and then markedly expanded and updated in March of 2007 (for June, 2007 publication in the AJR), the ACR Guidance Document for Safe MR Practices: 2007″ addresses numerous MR safety related topics, such as:

“There are increasing numbers of MR scans and an increasing demand to scan patients with implants or accessory medical devices and other equipment. With the increased use, we are also seeing a number of preventable incidents,” said Sunder Rajan, PhD, of the FDA’s Center for Devices and Radiological Health Division of Physics Biophysics Laboratory. “Given the new experience base, this is a good time for FDA to learn what MR practices are being used and what changes practitioners feel would improve safety to the MR environment.”

 

Is It Time For Regulation?

Industry leaders agree that you should have regular standards that provide for MRI safety. However, feelings around federal or state intervention are mixed.

“I’d love to see national guidelines, but I don’t know whether it needs to be federal regulation. Unequivocally, I’d like to see a set of objective standards applied to all MRI providers to ensure they offer a basic level of expertise and safety precautions in the MRI environment,” Gilk said. “Whether it’s federal regulation or an agreement between state licensing or accrediting agencies could help us take the needed steps toward preventing accidents.”
Kanal agreed that regulation is needed, but he said it needs to come from within the radiology community.

“We can either accept standards that we create and define, or we can wait for another terrible safety even to occur and be widely publicized throughout the world before pressure mounts on organized radiology to impose externally defined standards, guidelines, and practices upon us.”

GE reports The first X-rays to molecular medicine

 

This is a great article with some real history from GE. There are some Photographs below and more on there website. Be sure to follow up with Coolmristuff.com in a couple months when I speak with Mr. Michael Harsh about the future of GE’s medical division. Here at Coolmristuff.com we want to see what new technological advances GE is making in the medical field today. How will MRI, CT, &  PET make differences in the way routine diagnostic exams are done? What will be next? Will there ever be one scanner that does everything? hmm?………stay tuned.

Albert Einstein once noted that “imagination is more important than knowledge.” Yesterday on Capitol Hill, Michael Harsh, Vice President and Chief Technology Officer at GE Healthcare, quoted Einstein’s maxim in remarks at a U.S. Senate Special Committee on Aging forum on the future of healthcare called “Aging in America: Future Challenges, Promise and Potential.” Discussing healthcare innovation, Harsh said that knowledge was “limited to all we know while imagination embraces the entire world and all there ever will be to know.”

Yet knowledge and imagination are both the pillars of innovation. The record of Harsh’s business division, GE Healthcare, shows that the company stands firmly on both. In 1896 Willhelm Roentgen experimented with cathode-ray tubes and noticed that light was passing through solids. Referencing the mysterious light, he called the phenomenon X-rays and took a grainy picture of the bones in his wife’s hand. Just one year later, Thomas Edison and fellow GE engineer Elihu Thomson improved on Roentgen’s idea with insights from light bulb technology they had been developing and made the fluoroscope, the wFast forward to 1932, when GE’s Irving Langmuir won the Nobel Prize in Chemistry for his work that led to early coronary artery imaging. Forty years later, GE’s Ivar Giaever received the Nobel in1973 for research that made magnetic resonance imaging, or MRI, possible.

 

GE also employed Emile Gabby, who is known around the world as the father of mammography. Gabby developed a revolutionary x-ray tube design that made it possible to image soft tissue with unprecedented resolution. The positive impact on women’s healthcare is incalculable.

What innovations will change healthcare tomorrow? Most recently, GE’s scientists have been working on ways to combine the power of imaging technology with molecular biology and pathology. “We are moving from a healthcare paradigm where we ‘see and treat’ existing disease, to the ability to detect disease at the molecular level before physical symptoms emerge, and to treat that disease at a much earlier stage when it is much less costly to address and more advantageous to the patient’s quality of life,” said Harsh. Perhaps a breakthrough even Edison couldn’t have imagined.
