Please call 443-997-7237 to request an exam with Johns Hopkins Medical Imaging. Our call center is open Monday–Friday from 7:30 a.m.–6 p.m. and Saturday from 8 a.m.–noon.

Patients now have the convenience to self-schedule certain exams – these include screening mammograms, ultrasounds, CT without contrast exams, and DEXA appointment online through our patient portal (MyChart). Log on to MyChart or learn more about MyChart. If you aren’t signed up for MyChart, ask when you arrive for your appointment for an access code to register.
We welcome walk-ins for x-ray, DEXA, screening mammogram and selective CT exams. Please call our office in advance to ensure we can accommodate your requested exam. Walk-ins must arrive at least 30 minutes before closing time as listed below. Exam preps and insurance pre-authorization may exclude some patients from walk-in services.
To reduce wait time, we recommend whenever possible to schedule in advance.

For Annual Screening Exams

If a follow-up breast imaging exam is necessary, you will need your physician to complete a referral form.
Recent Lab Results for MRI or CT Exams Using Contrast
A blood test measuring creatinine levels is performed in advance of a MRI or CT exam using contrast to evaluate kidney function. This is to screen for potential pre-existing renal insufficiency in patients at high risk for contrast-induced nephropathy. Risk factors will be determined by the radiologist but include:
- Aged 60 or older
- History of renal disease, renal transplant, total nephrectomy or sickle cell crisis
- Diabetes mellitus
- Liver disease
- Recent surgery
- Acute deep vein thrombosis
- Previous allergic reaction to MRI or CT exam using gadolinium contrast
If you have any of these risk factors, you must have a blood test examining your kidney function within the last 30 days. You may either fax this to the office in advance or bring a copy with you to your radiology appointment.
If you do not have recent lab work, you might be eligible to receive the blood test on site when you arrive for your appointment.
Exams Using Contrast
In order to improve visibility of structures and organs inside the body, your physician may order an MRI, CT or X-ray exam that uses a contrast material.
Different types of contrast materials, such as gadolinium, iodine or barium sulfate, are used for different exams. Depending on the exam, the contrast may be inserted through an IV or given by mouth.
Please let the office know when you schedule the exam if you have an allergy to iodine. Your doctor may prescribe medications to take in advance of the exam.
