These are some of the services offered:

Call... Information about most Radiology services can be found at, a website created by the American College of Radiology for patients and physicians. tells you how various x-ray, CT, MRI, ultrasound, radiation therapy and other procedures are performed. It also addresses what you may experience and how to prepare for the exams.

The website contains over 115 radiologic procedures and is updated frequently with new information.  All material on the website is reviewed and approved by experts in the field of radiology from the ACR and RSNA, as well as other professional radiology organizations.

All of the services listed are provided at Howard university Hospital, except for PET/CT, where we send patients to another facility.

To schedule a study, call: 202-865-3610

2. X-Ray - What is a Chest X-ray (Chest Radiography)

The chest x-ray is the most commonly performed diagnostic x-ray examination. A chest x-ray makes images of the heart, lungs, airways, blood vessels and the bones of the spine and chest.

3. CT scan - What is CT Scanning of the Body?

CT scanning—sometimes called CAT scanning—is a noninvasive medical test that helps physicians diagnose and treat medical conditions.

CT scanning combines special x-ray equipment with sophisticated computers to produce multiple images  or pictures of the inside of the body. These cross-sectional images of the area being studied can then be examined on a computer monitor, printed or transferred to a CD.

What is Positron Emission Tomography – Computed Tomography (PET/CT) Scanning?

Positron emission tomography, also called PET imaging or a PET scan, is a type of nuclear medicine imaging.

A PET scan measures important body functions, such as blood flow, oxygen use, and sugar (glucose) metabolism, to help doctors evaluate how well organs and tissues are functioning.

Today, most PET scans are performed on instruments that are combined PET and CT scanners. The combined PET/CT scans provide images that pinpoint the location of abnormal metabolic activity within the body. The combined scans have been shown to provide more accurate diagnoses than the two scans performed separately.

For a PET/CT scan study, please contact: METRO REGION PET CENTER.
To schedule a PET/CT scan call 301-652-8001 (for Chevy Chase, MD) or FAX a completed referral form.

Referring offices should include all insurance information and recent imaging reports. The patient will be contacted upon receipt of the referral.

ACCREDITATION: The Howard University Hospital radiology department is accredited by the FDA as a Certified Mammography Facility (till March 2013), and mammography equipment was inspected and approved by the American College of Radiology (ACR) (Dec 2009 to March 2013). The  ACR also accredited Howard for OB, Gynecological & General ultrasound Services (July 28, 2010 through July 28, 2013). We are planning voluntary accreditation of CT and MRI services.
