Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is the gold standard imaging modality for soft tissues. It produces detail cross-sectional images of soft tissue and bone anatomy, including muscles, tendons, ligaments, brain and organs, without the use of ionizing radiation. In addition to orthopedic imaging, MRI is also used for heart, brain and breast. MRI uses gadolinium contrast in many exams to highlight tissues and blood vessels, which enhances images and offers better diagnostic quality. It can also be used in conjunction with PET scans. How does MRI work? MR creates images by using powerful magnets to polarize hydrogen atoms in water (the body is made of of more than 80% water) so they face in one direction. A radiofrequency pulse is then used to ping these atoms, causing them to wobble, or resonate. The MRI coils detect this and computers can assemble images from the signals. Basic MRI scans will focus on the resonance of fat and water in two different sequences, which highlight and contrast different features in the anatomy.

Combined, alcohol dependence and depression cause 'severe and extensive' brain connectivity impairment
Alcohol dependence and depression are known to affect the functional connectivity of the brain, but when the two co-occur, connectivity between certain regions is significantly worse, new MRI study shows.
PET is an energy hog, but relatively rare utilization lessens its carbon footprint. MRI and CT have no such ‘out’
Medical imaging machinery uses a lot of power, and the extent to which it quickens the pace of global warming is becoming clearer.
One adverse reaction to a GBCA significantly increases risk of another in the future
The type of gadolinium-based agent administered could also increase the risk of reaction, a new study suggests.
Princeton Radiology partners with AI startup to add full-body MRI service
The private practice is teaming with Ezra to offer the examination at its freestanding network of imaging centers in central and northern New Jersey.
Even two years after recovery, damage to multiple regions of the brain persists in COVID patients
On imaging some former COVID patients show significant alterations in several parts of the brain related to emotional regulation.

Why do some women with dense breasts skip supplemental MRI after a negative mammogram?

Most women with extremely dense breasts who decline the invitation to receive supplemental MRI after a negative mammogram do so because of “MRI-related inconveniences” or anxiety, according to a new study published by Clinical Radiology.

Research finds talking with radiographer calms patients before MRI

Nerves before an MRI are normal—up to 37 percent of patients report either moderate or high levels of anxiety leading up to an exam—and this apprehension can have physical consequences that render an entire scanning experience useless, first author J.R. Tugwell and colleagues wrote in Radiography this month.

Cheryl Petersilge, MD, MBA, with the department of regional radiology at the Cleveland Clinic, examined enterprise imaging—and how radiologists must integrate and collaborate with other departments. Her clinical perspective clinical perspective was published online in the October issue of the American Journal of Roentgenology.

Extracting radiomic features from MR images helps with breast lesion classification

Extracting radiomic features from MR images can help radiologists distinguish between benign breast lesions and luminal A breast cancers, according to a new study published by Academic Radiology.

Expensive imaging: New data reveal MRI prices highest in the US

The average price of an MRI in the United States is $1,119, higher than in any comparable countries, according to a new report from the Kaiser Family Foundation. The report examined the availability, utilization and prices of a variety of health services in countries all over the world.

Multicenter trial finds MRI-targeted biopsies superior to standard biopsies for diagnosing prostate cancer

When treating men with a clinical suspicion of prostate cancer, providers often turn to an ultrasound-guided biopsy of the prostate, though that method has been associated with missing clinically significant cancers and detecting clinically insignificant cancers.

Patients in yoga pants suffering burns during MRIs

If patients aren’t dressed appropriately when they undergo MRIs, they can suffer significant burns during the procedure. Due to small metal threads in the material, yoga pants and other similar clothing are a becoming a prime culprit.

ABVS means improved comfort, satisfaction for patients who would otherwise undergo MRI

Automated Breast Volume Scanner (ABVS) evaluation is close to matching traditional breast MRI in assessing tumor diameter and volume—and it’s leaving patients more satisfied and comfortable than its conventional counterpart, a study published in the European Journal of Radiology suggests.
