Tennessee Interventional and Imaging Associates

What Tennessee Interventional and Imaging Associates does

Tennessee Interventional and Imaging Associates (TIIA) is a private, subspecialty radiology practice headquartered in Chattanooga, Tennessee that provides diagnostic imaging interpretation and image-guided interventional procedures to hospitals, referring physicians, and patients across the southeast United States. The group's clinical scope spans the full diagnostic imaging stack (CT, MRI, ultrasound, PET/CT, nuclear medicine, mammography with 3D tomosynthesis, bone densitometry, X-ray/fluoroscopy, and pediatric imaging) plus a full interventional radiology suite that includes neurointerventional stroke care, interventional oncology (chemoembolization, Y-90 radioembolization, RFA, microwave ablation), uterine fibroid embolization, and vascular, GI/biliary, and renal interventions. All 18 radiologists on the roster are fellowship-trained across 8+ subspecialties, and the group supports 24/7 stroke interventionalist coverage that underpins Erlanger Health System's Comprehensive Stroke Center Certification from DNV GL Healthcare USA, Inc.

TIIA's technology footprint is built on advanced imaging hardware and protocol-level specialization rather than proprietary software: low-dose pediatric CT using ASIR reconstruction (45%+ dose reduction), 3D breast tomosynthesis, mechanical thrombectomy with stent retrievers and suction devices, and standard subspecialty PACS workflow. The group has accumulated 250,000+ diagnostic image interpretations as an institutional experience asset, and its physicians hold memberships in RSNA, ACR, SIR, ASNR, SPR, and TMA, supporting referral credibility. There is no public-facing API, no AI/ML product layer, and no proprietary technology platform disclosed; differentiation is delivered through clinical expertise and protocol depth, not software IP.

The business model is professional services fee-for-service billing through standard medical billing channels, with patient payment facilitated by the ImaginePay portal (3- and 6-month installment plans). TIIA has no consumer-facing sales motion; instead, distribution is anchored by exclusive or semi-exclusive hospital staffing agreements with Erlanger Health System and its affiliates (Erlanger Main, Erlanger East, Erlanger Western Carolina Hospital, Children's Hospital at Erlanger), Mountain Lakes Medical Center (Clayton, GA), and Siskin Hospital (Chattanooga, TN). Customer acquisition is referral- and partnership-driven, with a SharePoint-based physician portal supporting referring-physician workflow. The group is privately held, has no disclosed investors, no parent company, and no funding history in the source data.

Scale indicators4 records

Recent moves6 records

Expansion highlights4 records

Emerging players

• Rayus Radiology: National outpatient radiology platform owned by KKR focused on diagnostic imaging centers with growing subspecialty capability. Comparable in diagnostic imaging focus but skews more outpatient and consumer-facing than TIIA.
• Virtual Radiologic (vRad): Teleradiology platform providing remote diagnostic reads to hospitals and imaging centers nationwide. Emerging technology-enabled peer addressing the same hospital imaging demand that TIIA serves on-site.

Broad incumbents

• Envision Physician Services (Radiology): National multispecialty physician services platform with a significant radiology arm serving hospitals across the U.S. Comparable in hospital-based radiology delivery but embedded in a much larger multispecialty portfolio.
• US Radiology Specialists: PE-backed national radiology group providing diagnostic and interventional services to hospitals and outpatient centers. Broad incumbent comparable in service mix but operating at national scale versus TIIA's regional model.
• Radiology Partners: Largest physician-led radiology practice in the U.S., backed by private equity, operating across 30+ states. Comparable as a national operator of hospital-based radiology services but with vastly broader scale and capital access than TIIA.

Direct peers

• Charlotte Radiology: Subspecialty fellowship-trained private radiology group serving the Carolinas through hospital and outpatient imaging partnerships. Directly comparable regional subspecialty model with similar mix of diagnostic and interventional services.
• Atlanta Radiology Consultants: Subspecialty private radiology practice serving the greater Atlanta metro area with hospital and outpatient imaging. Closest geographic and structural peer to TIIA in the southeast region.

Regional players

• Birmingham Radiologists: Independent radiology group serving hospitals and imaging centers across Alabama with subspecialty reads. Comparable regional subspecialty practice operating in an adjacent southeast market.
