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.

Fluoroscopy in Southern California

Fluoroscopy is a real-time moving X-ray used to watch how organs and joints move — commonly used for GI, urologic, and joint-injection studies.

About Fluoroscopy

Fluoroscopy uses continuous low-dose X-rays displayed on a live monitor so the radiologist can watch how the GI tract, bladder, or a joint moves as contrast is introduced. It is the imaging test of choice for barium swallow, upper GI, small-bowel follow-through, voiding cystourethrogram (VCUG), and arthrograms.

Frequently asked questions

What does fluoroscopy show that an X-ray doesn’t?

Fluoroscopy shows movement in real time — how the esophagus swallows, how contrast fills the bladder, or how a joint moves — while a plain X-ray is a still image.

Will I need to drink barium?

Only for certain GI studies. For non-GI studies (such as arthrograms) the contrast is injected instead.

How much radiation is in a fluoroscopy exam?

Dose depends on the length of the exam. UMIH uses pulsed low-dose fluoroscopy and last-image-hold to keep total exposure as low as possible.
