III. T1 relaxation time
IV. The direction of water diffusion
V. T2 relaxation time ✔Correct Answer-Contrast in Diffusion Weighted Imaging (DWI) depends on

sequence to Brownian motion, and the direction of water diffusion
The final result in a perfusion study is ✔Correct Answer-A set of calculated images which indicate
various flow characteristics
The final result in a spectroscopy study is ✔Correct Answer-A spectrum of specific detected
metabolite
-Spectroscopy (MRS) allows doctors to obtain biochemical information about the chemical
components in tissues (metabolites) of the human body in a non-invasive way.

performing a task is: ✔Correct Answer-functional MRI
the corpus callosum primarily consists of ✔Correct Answer-white matter
If the TR in a gradient echo sequence is less than the T2 (or T2*), the resulting condition is known as:
✔Correct Answer-steady state
, A gradient echo sequence in which all the remaining residual transverse magnetization is removed
prior to the next excitation pulse is known as: ✔Correct Answer-incoherent or spoiled
In a Fast Spin Echo (FSE) sequence, acquired with a long TE, yielding T2 weighted images, scan time
can be reduced by: ✔Correct Answer-using longer ETL
In a Fast Spin Echo (FSE) sequence, acquired with a short echo time (TE), yielding T1 or PD weighted
images, blurring can be reduced by ✔Correct Answer-using shorter ETL

muscle and tendonIII. Infraspinatus muscle and tendonIV. Teres minor muscle and tendonV.
Supraspinatus muscle and tendonVI. Trapezius muscle and tendon ✔Correct Answer-II, III, IV and V
-The rotator cuff is comprised of the subscapularis muscle and tendon, infraspinatus muscle and
tendon,teres minor muscle and tendon and the supraspinatus muscle and tendon
T2 weighted FLAIR (fluid attenuated inversion recovery) sequences are typically used for evaluation
of: ✔Correct Answer-white matter disease
Short TAU inversion recovery (STIR) sequences are typically used for the evaluation of all the
following EXCEPT: ✔Correct Answer-fluid CSF
- Short TAU inversion recovery (STIR) sequences are typically used for the evaluation of compression
fracture, lesions within retro-orbital fat, musculoskeletal contusions and fat suppression
If the pulse sequence shown in Image 77 were a fast spin echo sequence, the number of lines of k-
space filled for each TR period would be: ✔Correct Answer-2
When a gradient echo sequence is selected for fast, breath hold dynamic contrast-enhanced imaging
of the abdomen, _____________ is utilized. ✔Correct Answer-spoiling
Gradient echo sequences requiring high signal from fluid are known as all of the following EXCEPT:
✔Correct Answer-incoherent GRE
- Gradient echo sequences requiring high signal from fluid are known as T2* gradient echo, Steady-
state gradient echo or coherent gradient echo. Incoherent gradient echo (or spoiled gradient echo)
sequences yield T1 contrast due to the removal of residual transverse magnetization before the next
excitation.

the following EXCEPT ✔Correct Answer-inversion time
