For those who prefer an app-style tool that works equally well on mobile devices. Try the new Signal, contrast & CNR for spin echo calculator.
| Page: MAIN | 1. Select tissue types from the drop down menus. 2. Vary the TR and TE. Use sliders or enter numerical values. 3. Read the normalised signal intensities, contrast and relative SNR. T1, T2 and M0 (proton density) for each tissue are indicated. |
| Page: GRAPHIC | View the normalised signal intensities, contrast and relative SNR in a graph whilst you vary the TR and TE. Note: the value scale adjusts to fit the screen, so always read the numerical values. |
| Page: FREE | Use this page to enter your own values of T1, T2 and M0 as Free 1 and Free 2. The values in MAIN will update accordingly. |
