For all its merits, MRI clinical imaging has limits that can hinder the quick and effective diagnosis of health problems in patients. For example, typical low-power (or ‘low-field’) MRIs produce reduced spatial and temporal image resolutions that can make it hard for medical practitioners to spot developing diseases.
‘Ultra-high-field’ MRIs – or scanners that produce more intense magnetic fields – can create more accurate and useful images. But their everyday use remains limited, in part because using conventional materials to produce stronger fields is a complex, expensive, and potentially hazardous task. For example, using too much power could overheat scanned bodily tissues, causing cellular damage.
