The 2 types of enhancement media described by Lauffer, the mechanism of T1 agents is - to decrease T1 relaxation time, thus emitting high signal An analogy for the decoding of the MR signal through Fourier Transform - Basilar membrane processing sound Logically each line of phase encoding data is combined to allow the FT to determine the position along the y-axis. The number of phase encoding steps determines - the number of pixels along the y-axis In a gradient echo pulse sequence, which ...

Practice Test 1 Armrit Exam Questions With Solutions different tissues that have signals that appear similar on a mr image are described as: isointense In a large main magnetic field such as those employed in MRI, the motion of a hydrogen proton has been described as wobbling like a spinning top. This motion is called: Prescession Magnetic resonance imaging is derived from the process known as: Nuclear magnetic resonance Once the net magnetization vector (nmv) has moved away from equi...
