How to Schedule Your Appointment

We are updating some appointment and procedure practices to help lessen the spread of the new coronavirus and COVID-19. In some cases, appointments or procedures may need to be rescheduled.

  • No walk-in exams are offered at any Johns Hopkins Medical Imaging location. This includes no walk-ins for any patient coming from on-campus clinic.

    If a same-day appointment for X-Ray or any other imaging exam is needed, the patient or referring provider’s office should call the imaging location directly to schedule.

  • Due to COVID-19, we will be making the following changes to upcoming mammogram appointments in order to maximize social distancing and reduce risk:
