Magnetic Resonance Imaging (MRI)
Magnetic resonance imaging (MRI) is a highly developed innovative technique that provides anatomic images in multiple planes and allows for information on tissue characterization. Images characterized by different tissues are obtained by varying the number and sequence of pulsed radiofrequency fields. Physical and chemical properties are used to identify these tissues. Unlike the images produced by x-rays, which are associated with the absorption of x-ray energy, MRI images are based on proton density and proton relaxation dynamics in a very powerful magnet.
The department of imaging at Johns Hopkins Bayview also offers several other specialized procedures, such as perfusion imaging, diffusion imaging, spectroscopy, HASTE imaging and an advanced method of angiography called FISP. These techniques help physicians more accurately detect and diagnose disorders ranging from kidney, gallbladder and heart disease to neurological problems, such as brain infarcts, tumors and seizure disorders.
In addition, Johns Hopkins Bayview offers the latest in state-of-the-art MRI scanners. Capabilities include multichannel head, spine, flex, wrist, body, knee and breast coils.
This cutting edge technology allows us to perform an array of procedures including:
- MRI ABD (liver, spleen, pancreas, kidney)
- MRI brain, C, T, L spine
- MRI breast
- MRI orthopaedic (shoulder, elbow, wrist, hand, hip, knee, ankle, foot)
- MRI pelvis
- MRA fisp (with contrast)
- MRA of the brain, neck, abdomen
- HASTE of ABD-A 13 second scan, which is very sensitive to obstructed kidneys, bile ducts and bowel loops
- Excellent angiographic quality images of most blood vessels

Johns Hopkins Bayview Medical Center has been granted the American College of Radiology (ACR) gold seal. The ACR gold seal of accreditation represents the highest level of image quality and patient safety. It is awarded only to facilities meeting ACR Practice Guidelines and Technical Standards after a peer-review evaluation by board-certified physicians and medical physicists who are experts in the field. Image quality, personnel qualifications, adequacy of facility equipment, quality control procedures and quality assurance programs are assessed. The findings are reported to the ACR Committee on Accreditation, which subsequently provides the practice with a comprehensive report they can use for continuous practice improvement.
