10 Questions
What does X-weighted, such as T1w or PD2, mean in MR imaging?
Parameter X will have the dominant role in defining tissue contrast
Is it always possible to correctly guess image weighting in MR imaging?
No, it is never possible
How many images are usually needed to correctly determine the weighting in MR imaging?
Two images are needed
What is the role of B0=1.5 T in MR imaging?
It is the strength of the magnetic field used
What is the order of tissue contrast values based on the table provided?
Fat, WM, GM, CSF
What does a T1w or PDw image mean in MRI?
T1w image means that T1 relaxation time has the dominant role in defining tissue contrast.
What is the role of B0 = 1.5 T in MRI?
It represents the magnetic field strength used in the MRI machine.
What does the value of 250, 60, and 0.9 represent for fat in the MRI tissue table?
T1 relaxation time, T2 relaxation time, and proton density of fat.
What does CSF stand for in the MRI tissue table?
Cerebrospinal fluid
What does the term 'X-weighted' mean in the context of MRI imaging?
It means that parameter X will have the dominant role in defining tissue contrast.
Test your knowledge of MR image weighting with this quiz by Professor Bashar Issa from the Department of Medical Diagnostic Imaging at the University of Sharjah. Learn if it's possible to accurately determine image weighting and understand if one image is sufficient to identify the weighting or if multiple images are required.
