Dual-energy X-ray imaging has traditionally been associated with large, fixed radiography systems and complex workflows. As a result, many healthcare leaders still assume the technology is expensive, difficult to use, or limited to niche applications.
Today, mobile dual-energy imaging is evolving. With single-exposure spectral X-ray technology, hospitals can now access dual-energy capabilities in portable and point-of-care settings—without the limitations of legacy systems.
Below are four common myths about dual-energy radiography, and what modern spectral imaging systems actually offer.
Myth 1: Mobile dual-energy X-ray systems are too expensive
Reality:
In the past, dual-energy imaging required specialized hardware and dedicated rooms. That is no longer the case.
Single-exposure mobile dual-energy X-ray systems are now priced competitively with premium mobile DR systems in the same category. This allows imaging departments to access spectral imaging without exceeding typical mobile radiography budgets.
As a result, dual-energy radiography is becoming more accessible for hospitals, outpatient centers, and critical care environments.
Myth 2: Dual-energy radiography is only useful for niche cases
Reality:
Modern spectral X-ray images are built on top of standard digital radiography (DR), so image quality and workflow remain consistent with conventional mobile X-ray.
Dual-energy images can provide additional information by separating soft tissue and bone structures. This capability is being explored in clinical and research settings across a growing range of applications, including:
-
Lung lesions and pneumonia
-
Line and tube placement
-
Pneumothorax and retained surgical objects
-
Musculoskeletal imaging
-
ICU decision support
-
Emerging research in coronary artery calcification visualization
In daily practice, mobile spectral systems function like standard DR units—with the option to access dual-energy views when clinically appropriate.
Myth 3: Dual-energy images slow down interpretation
Reality:
Some clinicians worry that dual-energy imaging increases reading time. However, multiple studies have shown that spectral images can maintain or improve reading efficiency.
Published research indicates that dual-energy imaging can:
-
Support faster interpretation in certain scenarios
-
Maintain reading times across varying experience levels
-
Improve visibility of abnormalities by reducing overlapping anatomy
As radiologists become familiar with spectral image formats, the additional views can support efficient clinical decision-making.
Myth 4: Without a billing code, dual-energy imaging has no ROI
Reality:
Clinical value is not limited to direct reimbursement. In many healthcare systems, especially those using bundled or capitated payment models, efficiency and resource utilization are critical.
Clinical experiences and published data suggest that spectral X-ray imaging can support:
-
Reduced reliance on follow-up CT in selected workflows
-
Earlier visualization of abnormalities during routine imaging
-
Minimal workflow disruption compared to conventional mobile DR
Rather than replacing CT or other modalities, mobile dual-energy X-ray can help optimize existing imaging pathways.
The Takeaway
Dual-energy X-ray imaging is no longer confined to specialized environments. With single-exposure spectral imaging, hospitals can integrate dual-energy radiography into routine workflows, without added complexity or cost barriers.
For imaging departments looking to improve diagnostic confidence while managing capacity and resources, mobile spectral X-ray systems represent a practical evolution of digital radiography.
