Which of the following produces high-resolution images of the structure of the brain without using x-rays?
A) a SQUID, or a superconducting quantum interference device
B) a PET scan, or positron-emission tomography scan
C) a CT scan, or computerized axial tomography scan
D) MRI, or magnetic resonance imaging

Question

Quizplus · Accepted Answer

MRI uses a magnetic field and radio waves to produce high-resolution images of the structure of the brain without using x-rays. A SQUID is used to measure very small magnetic fields and is not used for brain imaging. PET scans and CT scans use ionizing radiation, which is similar to X-rays.
