Small models used to scan lab rats also exist (a friend does research on brain damage prevention and I was wondering if they let her use human-rated machines for murine models).
- mattkrause 7y agoThe small-bore machines they use for rodents have much stronger fields: 9.4 and 11T field strengths are pretty common. This is a lot easier to achieve in a small bore. For comparison, the “standard” research scanners for humans are usually 3T, with 7T scanners becoming somewhat more available. That said, many universities do let people use the human scanners for other research. It’s kind of a pain to do with animals, because you’re paying $500 an hour while you scrub the room down afterward and wait for the air to cycle, but it’s the only way to scan larger animals (primates, pigs, dogs, etc).
