| Scan equation I don't get, HELP |
Here's the question:
The approximate scan time of a rapid spin echo sequence with a TR of 3500ms, a TE of 90ms, a 256x256 matrix, 1 exicitation, a 220mm FOV and an echo train length of 5 is______ minutes.
Formal they give is 3500msx1x256/5=?
a.3
b. 8
c. 11
d. 15
I get 179200. What am I missing in my studies and the math?

| Math equation |
Time in msec = TR * #phase_steps * NEX
Time in sec = (TR * #phase_steps * NEX) / 1000
Time in minutes = (-as above-) / 60,000
note: for FAST or TURBO spin echo divide the
#phase_steps by the ETL

James, I echo your feelings. I pretty much decided, after completing MIC, that maybe I really didn't want to take the registry! It is very intimidating.

| Which MRI machine to buy? |
Sandra,
Yes, this is our first MRI machine, we are currently a broker. Through more research I agree with you and have decided on finding a GE Echospeed Plus, they can be found for around 250k and seem to offer great "bang for the buck"
Your thoughts?
