VolumeRAD for lung nodule detection
The detection of lung nodules and subsequent patient management can be difficult with traditional chest radiography.
A recent international multicenter clinical trial has demonstrated that GE Healthcare’s VolumeRAD* Tomosynthesis imaging of the chest offers improved detection and management of patients with lung nodules compared to conventional radiography.
- Superior lung nodule detection sensitivity compared to conventional CXR (7.5 increase in lung nodule sensitivity for nodules between 4 mm and 6 mm diameter vs. standard X-Ray)
- Improved identification of cases that require follow-up  (1.5 times more sensitive than two-view CXR without decreased specificity)
- Improved conformity with guidelines for patient follow-up and care
- Improved sensitivity of detection of small lung nodules in the range of 3–20 mm in diameter; 3.6 times more sensitive than conventional two-view CXR, without decreased specificity
- A minimal-dose, volumetric imaging technique with the simplicity and efficient workflow of conventional chest X-ray; superior to CXR for lung nodule detection  (patients receive only 1.6 times more radiation than they do with a two-view (PA and LAT) chest X-ray exam)

In this webinar learn how one of the top academic radiology departments in North America is using VolumeRAD
Digital Tomosynthesis to improve the detection of small lung nodules.
Dr. Kicska, Associate Professor of Cardiothoracic Imaging at University of Washington
discusses the advantages and limitations of Digital Tomosynthesis and how this cost-effective technology could
be used to resolve inconclusive x-rays
"here and now", with minimal added radiation. Dr Kicska discusses:
- Basic principles of digital tomosynthesis, its advantages and limitations compared to standard radiography and CT
- Clinical cases where VolumeRAD is used to detect pathologic conditions of the chest
- Emerging applications of digital tomosynthesis in thoracic imaging
Some interesting clinical cases
 No clinical evidence has been established supporting the following claims in patients with active lung or pleural disease that could obscure pulmonary nodules, including fibrosis, emphysema, compressed lung, scarring, severe lung disease, and in patients with objects in or around the lungs that could obscure pulmonary nodules. The effectiveness of the device may vary depending on nodule prevalence and type.
