Dear Musculoskeletal Imaging Insider,
This issue of the Insider features a German study that examined whether 3-tesla MRI of the spine can be improved using a parallel radiofrequency (RF) technique.
Researchers from the University of Bonn found that the parallel RF protocol, also known as multitransmit MRI, produced diagnostic-quality images equivalent to those from conventional MRI among its patient sample.
The technique also reduced scan time for a whole-spine examination by 31% -- particularly benefiting patients who suffer from claustrophobia. Read more about this Insider Exclusive by clicking here.
This issue also features another study of parallel transmission: Researchers at the University of Vermont in Burlington obtained promising results on parallel transmission MRI's ability at 3-tesla magnet strength to improve image quality in the lumbar spine by reducing shading and other dielectric effects.
The study showed that the technique could be helpful when imaging large patients and patients who are in good physical condition with a low percentage of body fat.
In other news, read about how musculoskeletal ultrasound usage nearly quadrupled between 2000 and 2008, driven primarily by increased utilization by nonradiologists, according to a study from Thomas Jefferson University in Philadelphia.
And, radiologists can help surgeons in their tasks by changing the way they describe shoulder tears. A new study recommends that radiologists describe superior and posterior labral lesions as fraying and/or tearing in their reports to surgeons, unless radiologists can clearly see a displaced tear.
Finally, learn how research using different imaging techniques -- namely, CT and MRI -- showed that light exercise, such as walking and bowling, may protect people against developing osteoarthritis, while the location of fat in the body may contribute to the bone weakening seen in osteoarthritis.
