To analyze MRI features of neurogenic bladder and evaluate the value of MRI in its diagnosis, MRI manifestations of 16 patients with neurogenic bladder were retrospectively analyzed， and discussed with reference. During research we found 16 patients bladder all have expanded and retention， hereinto 12 patients bladder bottom widening， and its top became narrower， showed“A” shape. We can see this change clearly in T2WI photo and MRU； 15 cases bladder wall abnormal thickening and mucous membrane surface were uneven； 14 cases bladder wall protruded； 12 cases showed obvious bladder diverticulum under fat restriction observation. MRI & MRU are very useful in diagnosing neurogenic bladder. Check method for priority selection of lower urinary tract urinary storage and urinary dysfunction.
