Women & Infants Hospital said ultrasound images and some personal information for 14,000 patients in Rhode Island and Massachusetts are missing. The hospital said it cannot find backup tapes containing ultrasound images for patients who visited walk-in facilities in Providence and New Bedford. The records contained personal information, in some cases including Social Security numbers. The hospital said Monday on its website that it discovered the tapes missing in September. A hospital spokeswoman said the tapes contain data for nearly 1,200 patients who visited a facility at 79 Plain St. in Providence and more than 12,800 patients who visited a facility at 67 Brigham St. in New Bedford.
