In certain cases, a new method can provide as much information from brain images taken with computed tomography (CT) as images captured with magnetic resonance imaging (MRI). The method, presented in ...

Some types of scans include X-rays, computed tomography (CT), magnetic resonance imaging (MRI), and ultrasound scans. Medical professionals use scans to help diagnose a range of health conditions.

Non-enhanced CT scans were deemed helpful in only 4% of haemorrhage cases, primarily in gastrointestinal bleeding, while contributing substantially to the overall radiation exposure. An analysis of 75 ...

Each year, the US performs more than 93 million computed tomography (CT) scans, many of which offer limited clinical value. For patients with mild head injuries, CT scans are often ordered reflexively ...

For MRI scans, radiologists use gadolinium, a substance that alters the magnetic properties of water molecules in the human ...

Ancient pterosaurs may have taken to the skies far earlier and more explosively than birds, evolving flight at their very origin despite having relatively small brains. Using advanced CT imaging, ...
