ACR Accredited Facility
The Highest Level of Staff & Equipment Accreditation
The ACR awards accreditation to facilities for the achievement of high practice standards after a peer-review evaluation of its practice. Image quality and procedure evaluations are conducted by board-certified radiologists and medical physicists who are experts in the field. The program also evaluates personnel qualifications, adequacy of facility equipment, quality control procedures and quality assurance programs. 
Board Certified Radiologists
Certified by The American Board of Radiology
The mission of the American Board of Radiology is to serve patients, the public, and the medical profession by certifying that its diplomates have acquired, demonstrated, and maintained a requisite standard of knowledge, skill, understanding, and performance essential to the safe and competent practice of diagnostic radiology, radiation oncology, and medical physics.
Service With Care
Patient Focused Diagnostic Imaging
Valley MRI & Radiology is a patient focused imaging center. Our commitment to you as a patient is to provide the very best in diagnostic imaging services in a comfortable, safe and clean imaging center. We know that diagnostic imaging is an important part of your healthcare and have made this our professional priority as a center and staff .
Competitive Pricing
Emphasizing on Cost Containment
Diagnostic radiology is now the fastest rising area of medical expense, increasing at twice the rate of prescription drugs and faster than overall healthcare spending. Often times the same tests can be performed with identical equipment and equally experienced clinical staff, but at a more cost-efficient rate than other providers. At Valley MRI & Radiology we are aware of this rising issue and focus on offering the highest quality in diagnostic imaging at an affordable rate, focusing on cost-containment for our patients.
