Would anything show on MRI that wouldn't show on xray or ct scan with no dye.Swollen painful luq for 4 months. On and below ribs. Clear ct and xray.

Since the median nerve is very close to the usual veins utilized for IV injections, it is quite likely that chemical nerve injury has occurred. Other consequences may also be present. See your physician. ...Read more
