Tube and line placement confirmation is often treated as a simple visibility check — if you can see the device, you can confirm it’s in the right place. But in reality, it’s far more complex than that.
What happens if a feeding tube is in the wrong place?
If a feeding tube is placed incorrectly, it can pierce the esophagus, airway, or lungs. This can lead to serious complications such as:
- Aspiration (food or liquid entering the lungs)
- Esophageal perforation (food or liquid entering the chest cavity)
- Pneumonia or pneumothorax
- Airway obstruction
- Peritonitis caused by infection
- Ineffective nutrition delivery
What complication is most associated with incorrect endotracheal tube placement?
DES may improve diagnostic confidence by enhancing visualization of anatomical structures that overlap in conventional radiography.
Studies have demonstrated improved visualization of conditions such as pneumonia, lung cancer, pulmonary nodules, pneumothorax, coronary artery calcification (CAC), and tuberculosis. This makes subtle abnormalities easier to detect. Earlier visualization of subtle findings may support clinical decision-making when used alongside standard diagnostic pathways.
Many clinicians are working with portable X-ray images that compress anatomy into a single image, meaning ribs, soft tissue, and devices all overlap. Subtle misplacements, even just a few centimeters, can have meaningful medical consequences.
Just being able to see lines and tubes isn’t the same as knowing they’re in the right place.
The Clinical Reality: Why Misplacement Still Happens
Even when a tube or line appears to be correctly placed, it may not be.
It’s not just because the device is hard to see. More often, it’s because it’s hard to tell exactly where it sits compared to nearby anatomy.
In fast-paced environments like the ICU and ED, it’s not always possible to get the best imaging results for confirming line and tube placement. Many portable X-rays have limited clarity, especially compared to fixed X-rays machines with dedicated rooms. Additionally, overlapping structures can always obscure lines and tubes and make it difficult to confirm placement.
Often, the main driver of misplacement is limited contrast between structures. When different anatomical structures blend into each other, accurate assessment is difficult, even for experienced clinicians.
Is Incorrect Tube Placement A Common Issue?
Yes, line and tube misplacement continues to be a common issue for clinicians. NG tube insertion complications, for example, still occur in modern practice, even in controlled hospital environments. In 2024, 9 patients sustained injuries during NG tube placement attempts over ~16 months in a large academic medical centre.
While reported numbers may seem small, reducing line and tube placement complications is a top priority for many healthcare facilities. Misplacement can dramatically impact patient outcomes and leave healthcare facilities liable in cases of pneumothorax or even fatality.
Common Line and Tube Placement Complications
Incorrect placement can lead to serious problems, such as:
- A tube going into the esophagus instead of the trachea
- Pneumothorax after placing a central line
- A line being in the wrong position, leading to ineffective treatment
These issues are not always caused by an inability to see lines and tubes. Rather, difficulty distinguishing the device from surrounding anatomical structures is often what leads to misplacement.
Why Traditional Line and Tube Placement Confirmation Methods Fall Short
Conventional approaches address these challenges through image enhancement:
- Windowing and leveling adjustments
- Post-processing techniques
- AI-based tools that highlight lines and tubes
While these methods can improve visibility, they have a fundamental limitation:
- They do not separate anatomy.
- They do not resolve overlap.
- They do not improve the underlying signal captured during image acquisition.
Software can enhance what is already visible but can’t separate overlapping anatomical structures captured in a single image.
Why Imaging Context Matters
To confirm placement, clinicians need more than just a visible tube; they need context about the anatomical structures that surround it. Without clear differentiation between these structures, even a visible device can be difficult to interpret confidently.
This means understanding:
- Where the tube sits relative to the lungs, heart, or vessels
- The presence of surrounding pathology (e.g. consolidation, effusion, pneumothorax)
- How bones (like ribs or the clavicle) may be blocking the view
However, traditional single-energy X-ray systems often fail to provide this crucial context, since material separation isn’t possible. This ends up limiting clinicians’ ability to make confident, accurate assessments.
Spectral (Dual-Energy) Imaging for Context, Not Just Visibility
Spectral (dual-energy) X-ray imaging approaches this challenge differently, enabling separation of anatomical structures at the point of acquisition.
Rather than relying on post-processing alone, spectral imaging:
- Separates bone and soft tissue on acquisition, reducing structural overlap
- Improves material differentiation between devices and surrounding anatomy
- Provides additional image information that can support clinical decision-making
However, it’s important what spectral imaging technology you choose.
Many dual-energy technologies are not portable, disrupt workflows, necessitate multiple exposures, and require an X-ray grid, which can limit use in certain clinical environments like the ICU. This makes it hard to see dual-energy as a viable solution for line and tube placement confirmation.But the Reveal 35C detector, powered by SpectralDR® technology, challenges these limitations.
Reveal 35C: Supporting More Confident Tube Placement Confirmation
The Reveal 35C supports this more informed approach to placement confirmation by delivering multiple diagnostic images from a single X-ray exposure: a standard DR image, a soft tissue image, and a bone image.
Clinical studies using the Reveal 35C detector have suggested improved visualization of lines and tube tips without additional reading time
Key advantages include:
- Portable dual-energy capabilities without compromising image quality
- Additional image information without changing workflow
- No need for repeat exposures
- No need for an X-ray grid
- No increase in radiation dose
By providing separated views of anatomical structures, the system supports improved differentiation between devices and surrounding tissue. The Reveal 35C can be very effective in scenarios where tubes and lines intersect with dense anatomy such as the clavicle or spine, or when assessing placement against lung fields.
It may also support the identification of related complications, such as pneumothorax or fluid accumulation, by enhancing the ability to distinguish between tissue types.
Conclusion
Confirming tube and line placement is not just about spotting the device on an X-ray, it’s about understanding where it sits within complex anatomy. Overlapping structures and challenging imaging conditions can make confirmation difficult. That’s why adding more context is key. Enhancing visibility is one thing, understanding where exactly lines and tubes are is another.
By separating anatomical structures and providing additional image information, the Reveal 35C detector, powered by SpectralDR® technology, helps support more confident decisions when it matters most.
