T2-w FSE images before and after the intervention (pigs 5 and 4). (a, b) T2-w FSE images before and after the intervention (pig 5). Postinterventional T2-w images show a signal increase within the paravertebral muscle adjacent to the transverse process (blue arrows). No signal increase is seen in the region of the perivascular tissue (white arrow). (c, d) T2-w FSE images before and after the intervention (pig 4). Postinterventional T2-w images show a signal intensity increase adjacent to the transverse process (blue arrows) and in the periarterial tissue (white arrows).
