MRI

On February 8, 2011, a new cardiac pacemaker received approval from the FDA, which for the first time allows MRI procedures to be performed in patients by following specific labeling requirements. http://www.medtronic.com/mrisurescan. The “MR Conditional” Revo MRI SureScan Pacing System from Minneapolis-based Medtronic Inc. was designed to minimize the potential interactions with the electromagnetic fields used during MRI examinations.

MRI could help detect Alzheimer’s disease at an early stage - before irreversible damage has been done, according to the second recent study to examine MRI use for Alzheimer’s.

Using MRI may help researchers predict which adults are likely to develop Alzheimer’s disease, according to a new study published online and in the June issue of Radiology.

Five years after the first reports linking gadolinium-based MRI contrast agents to nephrogenic system fibrosis (NSF), separate presentations of post-marketing data from manufacturers and an independent prospective study supported by agencies in France have validated the low-risk status of the contrast agent Dotarem (Gd-DOTA).

Stroke in young adults is one of the leading causes of disability, and the third leading cause of death, according to the American Stroke Association. Yet with an early MRI scan and the right treatment, the effects from strokes can be can be completely reversed.

HealthDay News - Signs of spinal cord injury on MRI give indication of neurological prognosis after surgery

Nineteen percent of imaging studies ordered by Pennsylvania orthopedic surgeons were done solely for defensive medicine, and they accounted for 35 percent of the imaging costs, according to a study presented this week at the 2011 annual meeting of the American Academy of Orthopaedic Surgeons (AAOS).

Magnetic resonance imaging (MRI) and histological biopsy analysis are both efficient methods for subtyping hepatocellular adenomas (HCAs), according to a study published online Jan. 12 in Hepatology.

With Siemens close on its heels, Philips became the first company to get the green light to market its hybrid whole body PET/MR imaging system. Royal Philips Electronics announced this week that it received a CE marking, allowing the company to begin selling in Europe.

In assessing an osteoporotic patient for vertebral fractures, don’t overlook the vertebral endplates and the state of the intervertebral disks.

Top news from a featured radiology search on SearchMedica - patient monitoring in MRI: "Diffusion-weighted MRI May Predict Progression in Prostate Cancer"

Magnetic resonance imaging (MRI) can be used to monitor response during neoadjuvant chemotherapy (NAC), and it is effective in triple-negative or human epidermal growth factor receptor 2 (HER2)-positive breast cancer, according to a study published online Jan. 10 in the Journal of Clinical Oncology.

PET/MR is the logical next step in hybridization, the step that follows PET/CT, one that vendors finally took at this year's RSNA meeting. It has come a decade after PET/CT was first commercialized and nearly as long since pundits concluded that its arrival was inevitable.

People at risk of developing Alzheimer’s disease exhibit a specific structural change in the brain that can be visualized by MRI, a study by neuroscientists at Chicago’s Rush University Medical Center finds. The results may help identify those who would most benefit from early intervention.

Nearly a decade after PET/CT was first commercialized, vendors at RSNA 2010 took the next logical step and combined MR and PET. The result is unlike anything seen before.

Swiss researchers used susceptibility-weighted MRI and an artificial intelligence technique to help identify which individuals with mild cognitive impairment will continue to decline.

A 51-year-old woman presented to the clinic complaining of left heel pain.Tenderness and soft tissue swelling were observed. MRI reveals Haglund's deformity.

Contrast-enhanced FLAIR is more sensitive than other MRI techniques due to T2 prolongation and T1 shortening.

Current labeling already warns about the risks of gadolinium for patients with impaired kidney function.

From 1998 to 2007, the use of CT or MRI scans in emergency departments for injury-related conditions increased about three-fold without a similar increase in the prevalence of the diagnosis of certain life-threatening trauma-related conditions, according to a study in the October 6 issue of The Journal of the American Medical Association.

An insulin pump allows the replacement of slow-acting insulin for basal needs with a continuous infusion of rapid-acting insulin. By using an insulin pump, a patient can typically match the dosage of insulin to lifestyle and activities, rather than adjusting those to the body’s response to insulin injections. The advantages of using an insulin pump include the fact that an insulin pump replaces the need for periodic injections by delivering rapid-acting insulin continuously throughout the day via a catheter. It greatly simplifies the management of diabetes.

Magnetic resonance imaging is an established and important modality for the evaluation, assessment, and management of liver disease.

What set MRI on the path to where it is today was this modality’s ability to reveal, in strikingly realistic fashion, the mushy insides of our bodies. Whereas x-rays and CT scans showed our bony interior in stark relief, MRI excelled at showing our softer selves. That may be why it seemed so natural and fitting when fruits were used to see whether MRI scanners were working correctly. But I had never seen such scans as art, not until Andy Ellison got hold of them.

The very small may one day inherit the imaging world. Pioneers in nanoparticles are working toward that end, crafting imaging agents to hasten the future of MRI. But lately imaging alone just hasn’t been enough to excite me. Nor has it been enough that these nano agents are about 1/10,000th the diameter of the diminishing hairs on my head.

Good news radiologists! There’s a new place to set up that MRI machine: the guidance counselor’s office. Researchers are starting to use MRI to document an individual’s ability to perform on vocational guidance tests.

Every so often you come across an idea that has so much merit you can’t imagine why somebody hadn’t come up with it before. Such is the case with hospital gowns matched to a patient’s skin color. Although sky blue and forest green might be stunning on the right patient, it is hard to imagine either one helping docs spot signs of diseases that can be found in skin color changes.

Thirty years ago, I counted 12 MRI machines worldwide. Once the total had passed 25,000, I gave up counting.

A growing body of data is linking sportsrelated concussions to brain damage associated with cognitive impairment.

Cardiovascular MR (CMR) has evolved rapidly over the past decade, with the results feeding into a broad spectrum of clinical and research applications.
