Hunt Regional Open Imaging of Rockwall

Daniel M. Dow, MD

The successful diagnosis and treatment of patients is largely determined by innovative technologies.

If and when your physician orders specialized images for you or your family, you want to have the best facility with the most advanced technology and equipment perform those services. No need to drive across the lake to find quality, professional imaging services. Hunt Regional Open Imaging in Rockwall provides convenient, comprehensive imaging services in a comfortable, pleasant environment. At (HROIR), you’ll have access to the latest equipment, training, and technology, allowing you to be certain you’re receiving the best quality imaging and services delivered in the safest, most comfortable, patient-centric manner available.


The facility’s quality imaging technology includes 3T MRI, 64-slice Low Dose CT, and digital X-rays. 3T technology offers a high resolution and unique motion correction feature, which improves image quality and reduces examination scan time. “Our Siemens Magnetom Verio provides clinical and operational advantages to not only patients, but their referring physicians, as well,” Dr. Dow said. “The new MRI and CT scanners both offer superior image quality and improved diagnostic capabilities for every patient,” Dr. Dow stated. “The Verio’s 70-cm open bore design can improve positioning, enhance patient comfort, and decrease imaging time.” Less padding and lightweight coils allows more space for larger patients up to 550 lbs.

64-slice CT Scans

The Siemens Perspective 64-slice CT scanner provides you with low-dose CT exams, which is beneficial for pediatric patients, as well as patients having multiple exams. The Perspective 64 is also excellent for radiological assessment in oncology to reliably find and measure tumors and metastases. Scans are painless with a remarkably fast image acquisition. “Our policies and protocols are designed to provide excellent diagnostic images while focusing on reducing radiation exposure,” said Dr. Dow.

Digital X-ray

The utilization of digital X-rays means shorter exam times with less radiation exposure for patients. With advanced digital X-ray, dense tissues in the body, such as bones, appear white on X-ray films, while less dense tissues, like muscles and organs, appear in shades of gray. A detector processes and records images digitally, which can then be viewed on screen and saved immediately on a computer system. Dr. Dow is then able to interpret your exam and forward the results of your digital X-ray directly to the healthcare provider who ordered them. Because the technologist doesn’t have to process film and can see the results immediately, digital X-rays require fewer retakes and delays.

MRI and CT Arthrograms

Hunt Regional Open Imaging also provides MRI and CT arthrograms, which improve the diagnostic capabilities of MRI and CT in evaluating musculoskeletal joints and determining the etiologies of joint pain. Utilizing image guidance, Dr. Dow injects contrast dye into the joint. Then, an MRI or CT is performed to examine the joint. “Arthrograms increase the ability of MRI and CT to detect rotator cuff and labral tears of the shoulder and labral tears of the hip, as well as other internal derangements of the joints,” Dr. Dow said. MRI arthrograms may be performed on numerous joints including the shoulder, hip, elbow, and knee.

Instant Image Accessibility and Viewing

Hunt Regional Open Imaging also offers efficient online viewing capabilities so your referring physicians can easily access and view your images and reports anytime, anywhere. Physicians can view images and reports with their smart phones or other web-enabled devices instantly. Providing this technology is another way Hunt Regional Open Imaging seeks to bring value and convenience to its patients.

Meet Dr. Dow

Dr. Dow received his Bachelor of Science degree from the University of Texas at Austin, where he graduated with honors. He attended the University of Texas Health Science Center in San Antonio and was elected to the Alpha Omega Alpha Honor Medical Society. He earned his medical degree in 1999 and completed his internship in 2000, followed by his diagnostic radiology residency in 2004 at the University of Texas Southwestern Medical Center, Parkland Memorial Hospital in Dallas. He joined Open Imaging of Rockwall in November 2005. Dr. Dow is board certified by the American Board of Radiology.

Dr. Dow has been with HROIR since their doors opened in December of 2005, while the technologists have been on board for a combined 33 years—a testament to their dedication and loyalty. “It’s comforting for patients to see a familiar face when they come in for routine scans, and we feel that this consistency has helped establish our reputation and maintain our message of patient-centric care,” Dr. Dow said. Physicians can make recommendations for medical imaging based on insurance or location, but ultimately patients always have a choice. “Our mission is to offer exceptional care, which we are able to accomplish with advanced technology, on-site and board certified radiologists, and registered technologists. We meet the needs of our patients and referring physicians by providing fast, accurate, and highly detailed results.”
