A comparison of human brain scans using the NexGen 7T MRI at higher resolution (left) vs a conventional 7T scanner (middle) and the standard 3T hospital scanner (right). With higher resolution, ...

High-field magnetic resonance imaging (MRI) machines can work better by changing the structure of radio probes from coils to antenna-like structures. How can you make an MRI scanner work properly at ...

A scientific team supported in part by the National Institutes of Health (NIH) has developed a new, ultra-high-resolution brain imaging system that can reconstruct microscopic brain structures that ...

Heart attack and stroke are the first and second leading causes of death in developed countries, respectively. As the disease often results in sudden death with few special prognostic symptoms, early ...

According to an article in ARRS' American Journal of Roentgenology (AJR), brain volume measurements in memory-impaired patients show significant differences and systematic biases between conventional ...

A review of cases using MRI with and without contrast agent found perfect or near-perfect agreement in most cases when evaluating patients with short stature for growth hormone deficiency. Gadolinium ...

The report suggests that high-resolution micro-ultrasound could help identify clinically significant lesions that would be missed with conventional MRI. High-resolution micro-ultrasound (micro-US) ...

A new study in Engineering introduces a novel MRI technique enabling real-time, artifact-free navigation of magnetic robots.

Hospital MRI scanners, using 3 Tesla magnets, provide poor spatial resolution in brain imaging. More recent 7T MRIs are better but used mainly in the rare research lab. Scientists have now ...
