The MRI scanner can pick out a very small point inside the patient's body and ask it, essentially, "What type of tissue are you?" The system goes through the patient's body point by point, building up a map of tissue types. It then integrates all of this information to create 2-D...
and physics professor Peter Mansfield from the University of Nottingham in England, individually used magnetic resonance as the basis for developing a new diagnostic technique, called magnetic resonance imaging. The first commercial MRI scanner was produced in 1980. ...
super strong magnets. Hydrogen is present in water, fat, protein, and most of the "soft tissue" structures of the body. The doughnut of an MRI does not house a rotating x-ray machine as it does in a CT scanner. Rather, it houses a ...
For some procedures, especially intestinal and circulatory scans, the patient will need to take a contrast agent for the most accurate scans. Bone and other dense structures within the body are easily imaged with the CT scanner’s x-rays; however, soft tissue does not appear as readily without...
This can cause interference with the imaging techniques done by an MRI scanner, or harm to the patient receiving the scan. CT scans are quick, low-risk procedures that provide detailed images of bone, tissue, and organs, and are more commonly recommended by doctors. Why is a CT scan ...

How does a VLF metal detector distinguish between different metals? It relies on a phenomenon known as phase shifting. Phase shift is the difference in timing between the transmitter coil's frequency and the frequency of the target object. This discrepancy can result from a couple of things: In...
How does the vestibular sense work? How does an aquatic ecosystem work? Describe and explain how an MRI scanner produces images. How do semilunar valves work? How do waves change as they approach the shore? Explain how a seismograph records earthquake data. ...
A job interview in the MRI scanner: How does indirectness affect addressees and overhearers? Neuropsychologia. 2015;76:79-91Basnakova, J., van Berkum, J., Weber, K., Hagoort, P. (2015). A job interview in the MRI scanner: how does indirectness affect ad- dressees and overhearers?
The PET scanner machine detects these gamma rays, and with the help of advanced computing technology, the machine can create a 3D image of the brain’s activity. At times, PET scans are used in conjunction with other brain imaging techniques like a CT scan or fMRI to get enhanced informatio...
