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.

Hospital apologizes after leaving patient on MRI scanner for 6 hours
The institution has reportedly suspended multiple members of its staff and is implementing shift-change procedures in the wake of the incident.
Experts develop first-of-its-kind fully robotic MRI-compatible system for neurosurgery
BrainBot's development represents a significant step forward for image-guided interventional procedures, as fully robotic neurosurgical devices are not designed to be MRI-compatible.
MRI findings detail distinct ADHD subtypes
Findings from the study provide new insight into the heterogeneity of the disorder, which could help explain why some children seem to respond better to common treatments than others.
Bayer's MR contrast injection system cleared by FDA for expanded use
The updated clearance expands the system's labeled field strength compatibility; the change will allow MRI suites with scanners up to the 7T range to utilize the system.
Ultrasound isn't cutting it for diagnosing pediatric appendicitis, new data show
Instead, rapid MRI protocols may be the key to addressing diagnostic questions in cases of suspected appendicitis in kids, researchers contend.

The new MRI contrast agent gadopiclenol, sold under the trade names Elucirem and Vueway by Bracco and Guerbet, used 50% less gadolinium that current MRI agents. #RSNA22 #RSNA

FDA approves expanded use of gadolinium-based imaging agent

Gadopiclenol is a macrocyclic high-relaxivity GBCA that contains less than half the amount of gadolinium that standard agents are formulated with.

Combining PET and MRI data helps distinguish between LATE and Alzheimer's

Combining PET and MRI data may be key to differentiating new type of dementia

Limbic-predominant age-related TDP-43 encephalopathy, also known as LATE, was recently recognized as a type of dementia that occurs in older adults. It typically presents as memory-related cognitive decline.
