  • Pick up the contrast the day before your appointment at either the Touro Imaging Center or Touro Radiology Department (3rd floor, hospital). When you make the appointment, Touro scheduling will direct you to the appropriate location. If your appointment is on Monday, pick up the contrast by the Friday prior between 7 a.m. and 5 p.m.

Barium contrast is not absorbed into the body; it passes through your colon which may cause loose stools.

Contact your physician or come to the Emergency Room if you experience any shortness of breath or chest pain after drinking the contrast material.
