TRoom = time that the room is occupied by patient. TProcedure = time required for injection (skin to skin), TRadiologist = overall time radiologist in the US or fluoroscopy room
USa: US-guided anterior injection, USp: US-guided posterior injection, FLa: fluoroscopic-guided anterior injection, FLp: fluoroscopic-guided posterior injection. FL(a + p): fluoroscopic-guided anterior and posterior injection, US(a + p): US-guided anterior and posterior injection, TUS:TFL: percentage of needed room, procedure and radiologist time with US guidance in relation to the time span for fluoroscopic guidance
