Instructions

Explore each of the MR weighted scan types on Panel 1 on the right. Hit "RUN" and note how contrast changes with each of them. Refer to the Messages Panel for further directions.

Task

Answer the question below to test your knowledge and move on to the next task!
Which scan makes CSF look dark?

{% for subfield in G3Form.P1_q %} {% if subfield.id == "P1_q" %} {{ subfield(class="btn-check ", autocomplete="off",checked=session['game3']['P1_q']=='T1') }} {% elif subfield.id == "P1_q-1" %} {{ subfield(class="btn-check ", autocomplete="off",checked=session['game3']['P1_q']=='T2') }} {% else %} {{ subfield(class="btn-check ", autocomplete="off", checked=session['game3']['P1_q']=='PD') }} {% endif %} {{ subfield.label(class="btn btn-outline-primary d-flex align-items-center justify-content-center") }} {% endfor %}

Instructions

Experiment with different TR, TE, and FA values to observe how each changes the contrast. Test out the following TR, TE, and FA values on the second panel.

  • 1. A high TR (4000 - 5000 ms) with a low TE (0 - 150 ms)
  • 2. A low TR (500 - 1500 ms) with a low TE (0 - 150 ms)
  • 3. A high TR (4000 - 5000 ms) with a high TE (350 - 450 ms)

Task

Answer the question below to continue to next task!
At TR = 500 ms, TE = 0 ms, what happens as the flip angle approaches 90 degrees?

{% for subfield in G3Form.P2_q %} {% if subfield.id == "P2_q-0" %} {{ subfield(class="btn-check ", autocomplete="off",checked=session['game3']['P2_q']=='Contrast Decreases') }} {% elif subfield.id == "P2_q-1" %} {{ subfield(class="btn-check ", autocomplete="off",checked=session['game3']['P2_q']=='Contrast Increases') }} {% endif %} {{ subfield.label(class="btn btn-outline-primary d-flex align-items-center justify-content-center") }} {% endfor %}

Instructions

1. Click through preset T1w, T2w, and PDw scans on the first panel and hit "RUN" to observe how signal intensities of CSF, GM, and WM change in Panel 3.
2. Change each value on Panel 2, hit "RUN", and observe how it changes the signal intensities of CSF, GM, and WM in Panel 3.
3. Answer the queries in the Question panel to earn up to five stars!

Task

Answer the question below:
In a T2 weighted scan, which tissue type results in the most signal intensity?

{% for subfield in G3Form.P3_q %} {% if subfield.id == "P3_q" %} {{ subfield(class="btn-check ", autocomplete="off",checked=session['game3']['P3_q']=='CSF') }} {% elif subfield.id == "P3_q-1" %} {{ subfield(class="btn-check ", autocomplete="off",checked=session['game3']['P3_q']=='GM') }} {% else %} {{ subfield(class="btn-check ", autocomplete="off",checked=session['game3']['P3_q']=='WM') }} {% endif %} {{ subfield.label(class="btn btn-outline-primary d-flex align-items-center justify-content-center") }} {% endfor %}
