Hello,
Does anyone know what the recommended weight limit is for the 3T scanner? Also, can anyone provide any weight limit guidelines for the mock scanner?
Thank you!

| i don't think there is a weight limit for the scanner ... its all about if the subject can fit into the scanner bore. |

| I've run someone in the 3T who was around 230, but she was a tight fit. Also though, height sort of matters. If someone is 5'3'' and 250, they will almost certainly not fit comfortably, but maybe if they were like 6'1'' and 250 it could work. |

We have used 300 Lbs to exclude subjects at screen time. But we have had people who weighed 250, and could not fit (wide and short you know). So we have developped a hoola-hoop that matches the width of the scanner, and we simply measure them through that. I have to say that it is quite uncomfortable to measure people, so having a weight limit from the outset helps avoid embarassing situations.
Alternatively, you can also measure the diameter of the bore, and measure the subjects shoulder, chest and abdominal regions, if you want to be sure. It is certainly worth $800 to do that, rather than have to cancel a scan. |

Our subject recruitment procedures are to scrutinize anyone over 250. For a clinical subject, we have run someone as large as 290 (reported weight). I would not recommend this, unless absolutely necessary. It's uncomfortable for the subject, and contributes to motion.
It most depends on the subject's weight distribution (a tall, highly dense, 250 pounder person may not be as much of a problem as a short, less dense person, or someone who has all of their weight at their belly (a problem)).
I would suggest testing the person out in the mock scanner room. |
