A spin echo imaging sequence with moderate T2 contrast was used to generate the first high resolution MRI of an adult D. bifurca with false color segmentation. No contrast agent was administered to the specimen in this case. We observed that specimens prepared with contrast agent administration yielded comparable signal strength with the relaxation time (TR) reduced to as little as one-tenth of that used without contrast agent, dramatically reducing the total acquisition time.
3D rendering from 2D slices. Sequence: Spin Echo Multi-Slice, 12.5 micron in-plane resolution, 100 micron slice thickness, TR=1500 ms, TE=20 ms, matrix: 128x128, FOV: 1.6x1.6 mm.
Experiments performed at Stanford University, Magnetic Resonance Laboratory (SMRL)
