Magnetic Resonance Imaging (MRI)

MRI creates images from the magnetic resonance created in hydrogen atoms when they are polarized and an electromagnetic pulse is used to knock them off axis. This section includes MR analysis software, MRI scanners, gadolinium contrast agents and related magnetic resonance imaging accessories.

Two magnetic resonance imaging (MRI) findings — joint capsule edema and thickness at the axillary recess, specifically — proved useful in predicting stiff shoulder in patients with rotator cuff tears, according to an ahead-of-print article in the May issue of the American Journal of Roentgenology (AJR)

This image is of an 80 kg woman with a newly diagnosed IDH-wildtype glioblastoma

This image is of an 80 kg woman with a newly diagnosed IDH-wildtype glioblastoma. The quarter dose image on the left was obtained after the administration of 4 ml of MultiHance. Subsequently, an additional 12 ml of MultiHance was administered and the cumulative full dose image in the center was obtained. The image on the right was rendered following artificial intelligence processing of the 4 ml image using eGad genetic algorithms. This image has the quality of triple dose gadolinium even though only one quarter dose gadolinium was given.

The researchers used high resolution cross-sectional imaging with CT or MRI to assess 225 men with abdominal aortic aneurysm. Follow-up lasted, on average, more than three years.  Slightly more than half of patients had an intraluminal thrombus. The aneurysms of those with intraluminal thrombus were larger at baseline and grew by a rate of 2 mm per year, twice as fast as the 1 mm per year growth rate in people without intraluminal thrombus.
