2025/09 - Operational Costs of 4D Flow MRI: A Break-Even Analysis [Journal Club]-September JCMR Webinar

Video Transcription

Video Summary

The JCMR Journal Club session featured a presentation from Northwestern investigators on the paper <strong>“Operational Costs of 4D Flow MRI, a Breakeven Analysis.”</strong> The talk explained what 4D flow MRI is, its clinical applications across aortic, valvular, congenital, pulmonary, and atrial disease, and why it offers workflow advantages over standard 2D phase-contrast imaging.  

The presenters built a financial model dividing costs into fixed, variable, and opportunity costs, including scanner time, software, and physician post-processing. They also reviewed current reimbursement rules, noting that 4D flow is billed as an add-on CPT code and recently gained the ability to be billed up to four units. Their analysis suggested that, under typical assumptions, a center would need roughly <strong>300–700 scans per year</strong> to break even, with fewer scans needed if highly accelerated acquisitions are used.  

Discussion focused on reimbursement realism, workflow consistency, software costs, accelerated scan feasibility, and the need for better quantitative outcomes data. The session concluded that broader adoption of 4D flow will depend on faster acquisitions, improved reimbursement, and stronger evidence showing clinical and economic benefit.
