HMI

What HMI does

Houston Medical Imaging (HMI) operates a network of 14+ outpatient diagnostic imaging centers across the Houston metropolitan area, including sites in Houston proper (Campbell, Shepherd, Heights, Energy Corridor, Jacinto City, Steeplechase, Global) and surrounding communities (Richmond, Sugar Land/Fort Bend, Pearland, Tomball, Edinburg, Brooks Lake). Founded in 1998 and headquartered in Houston, the company delivers a comprehensive suite of imaging modalities — MRI/MRA, CT, PET/CT, ultrasound, nuclear medicine, fluoroscopy, 3D mammography, breast MRI, prostate MRI, DEXA bone density, low-dose CT lung cancer screening, cardiac imaging, neuroradiology, and high-field open MRI — supported by board-certified subspecialty-trained radiologists. Specialty programs include Enhanced Breast Cancer Detection (EBCD) mammography, enhanced prostate screening, and walk-in X-ray and walk-in 3D screening mammogram services accessible without physician order for patients with an active primary care provider or OBGYN.

The company's revenue model is fee-for-service professional radiology: imaging procedures are billed to insurance or self-pay patients based on referring physician orders, with walk-in X-ray and mammogram services as direct-to-consumer entry points. Go-to-market combines direct patient scheduling via phone (713-797-1919) and online portals with a distributed physician referral network coordinated through the RadNet provider portal at radnetconnecttx.com and fax ordering to 713-383-9933. Marketing reaches Houston's diverse population through a multilingual website (English, Arabic, Spanish, French, Chinese, Korean, Japanese, Vietnamese) and an X (Twitter) presence via rad.link. HMI is HIPAA-compliant and operates as a regional subsidiary within the RadNet national radiology network, which centralizes careers, patient portals, and corporate policies.
