Providing Highly Advanced Diagnostic Imaging Services

At United Medical Imaging Healthcare (UMIH), we put our patients at the center of everything we do. Over the past two decades we have built a comprehensive outpatient radiology network across Los Angeles and Orange counties, serving more than 300,000 patients each year through 32 full-service facilities.

Every UMIH center is accredited by the American College of Radiology (ACR) and staffed by fellowship-trained radiologists covering musculoskeletal (MSK), breast, and neuroradiology subspecialties.

What we offer

  • 3T and 1.5T high-field MRI, wide-bore MRI, and open MRI for claustrophobic or larger patients
  • 128-slice CT and CT angiography (CTA)
  • PET/CT for oncology staging, restaging, and treatment response
  • 3D digital mammography, breast ultrasound, and image-guided breast biopsy
  • Diagnostic ultrasound, DEXA bone density, fluoroscopy, and digital X-ray
  • Nuclear medicine including bone scan, HIDA, MAG3 renal, and cardiac perfusion

Fast, patient-first scheduling

Same-day and walk-in appointments are available at most locations (unless the study requires prior authorization or extensive prep). Referring physicians typically receive our specialty diagnostic reports within 24–48 hours of the exam.

Extended hours are available at select locations (Monday–Friday 7:30 am to 7:00 pm, and Saturdays on request). For scheduling assistance call (310) 943-8400 or request an appointment through our patient portal.

About MRI

MRI is the imaging test of choice for evaluating soft tissue, cartilage, ligaments, the brain, the spinal cord, and internal organs. Because it uses magnets instead of X-rays, MRI involves no ionizing radiation, which makes it appropriate for repeat exams and for many pediatric and pregnancy-safe scenarios. UMIH’s high-field MRI systems produce diagnostic-quality images across musculoskeletal, neurological, abdominal, and breast studies, and are read by fellowship-trained subspecialty radiologists.

When MRI is used

  • Brain and spine evaluation (stroke, MS, disc disease, tumors)
  • Knee, shoulder, hip, and other joint injuries
  • Soft-tissue tumors, lymph-node evaluation
  • Abdominal and pelvic organ imaging
  • Breast MRI for high-risk screening and implant evaluation

Preparation: Wear metal-free clothing or expect to change into a gown. Tell the technologist about any implants (pacemaker, cochlear, aneurysm clips, spinal stimulator). Some abdominal or pelvic MRIs require 4 hours of fasting; contrast studies need current kidney function labs.

Typical duration: Most MRI exams take 20 to 45 minutes.

Radiation: No ionizing radiation.

Frequently asked questions about MRI

Does an MRI use radiation?

No. MRI uses a strong magnetic field and radio waves, so patients receive zero ionizing radiation.

How long does an MRI take?

Most MRI exams take between 20 and 45 minutes. Longer protocols (breast MRI, multi-region studies) can take up to an hour.

Can I have an MRI if I have metal implants?

Many modern implants are MRI-safe, but you must disclose every implant to the technologist first. Pacemakers, cochlear implants, some aneurysm clips, and certain neurostimulators may be contraindicated.
