Despite the prevalence of MRI in clinical practice, it still has one weakness: low sensitivity. This issue is usually combatted with agents injected into patients to achieve high spatial and temporal resolution. A team of École Polytechnique Fédérale de Lausanne researchers has discovered a natural compound that produces the same high resolution in contrast enhanced MRI, according to Science Daily’s “A Natural Boost for MRI Scans,” published Oct. 21 online.

Getting an MRI can be an uncomfortable experience for some, especially for children that may be frightened by the loud noises and tight confines. Sedation is an option, but that involves its own risks, albeit rare, for young patients. KING 5 news in Seattle highlighted one hospital’s program to boost kids’ confidence when facing an MRI machine and help train them to undergo a drug-free MRI.

Stanford University researchers have leveraged MRI exams to uncover a link between a student’s hippocampus and his or her ability to respond to intensive math tutoring. Struggling math students with a larger hippocampus demonstrated greater improvements in math performance after intensive tutoring. Read more at the link below.
