Financing diagnostic imaging: lease or buy for a growing practice?

A digital radiography system or ultrasound unit is a large enough purchase — full systems commonly run into the low six figures depending on configuration — that the financing decision affects practice cash flow for years, not just the month of purchase.

Three signs it’s time to finance, not pay cash

Paying cash that drops working capital below a comfortable buffer for payroll and supply purchases is the clearest signal to finance instead. A failing existing unit that needs replacing on short notice — rather than a planned upgrade — is another, since there’s no time to save toward it. And if the new equipment unlocks revenue fast enough to cover the monthly payment (bringing imaging in-house that the practice previously had to refer out), financing the equipment is financing growth, not just a purchase.

Lease vs. loan

A loan builds equity in the equipment and is generally the lower total-cost option if the practice plans to run the system for its full useful life. A lease keeps the equipment off the balance sheet as debt and often comes with lower monthly payments — useful if the practice wants to preserve borrowing capacity for other purposes — but total cost over the equipment’s life is usually higher than an equivalent loan, and leases sometimes restrict usage volume in ways a busy diagnostic schedule can exceed.

What lenders look at

For equipment-secured financing, lenders weigh time in practice, revenue, and credit — but because the equipment itself serves as collateral, approval is generally easier than an unsecured loan, and rates are typically better. Terms commonly run 5–7 years depending on the equipment’s expected useful life.

Section 179 and bonus depreciation

New or used diagnostic imaging equipment used for business typically qualifies for Section 179 expensing up to the annual cap, plus bonus depreciation on remaining basis — meaningful enough on a six-figure purchase that it’s worth modeling with an accountant before deciding lease vs. buy, since the tax treatment differs between the two structures.

Bottom line: finance when cash would otherwise be tied up in a single asset for years; choose loan over lease if you plan to run the equipment to the end of its useful life, lease if preserving balance-sheet flexibility matters more than total cost.
