Overview

VolumeRAD digital tomosynthesis

Today clinicians rely on standard radiography as the first diagnostic test for most chest, orthopedic and trauma cases. Advanced medical imaging is often ordered for complex cases that radiography cannot solve. These additional imaging modalities may result in higher radiation exposure, higher imaging costs, and a delay in diagnosis & treatment that could also mean more anxiety and discomfort for the patient.

VolumeRAD Digital Tomosynthesis brings 3-dimensional imaging into your radiography room, helping you resolve inconclusive x-rays quickly, inexpensively, and with the same equipment.

With VolumeRAD:

  • Reduce unnecessary exams following an inconclusive x-ray and free-up your other imaging systems for demanding cases

  • Detect wrist fractures with over 20 times less dose than a CT exam

  • Make a confident diagnosis with 95% sensitivity for wrist fracture detection and 42% sensitivity for occult wrist fractures

Enhance your care pathway with VolumeRAD 

Advanced medical imaging is often ordered for complex cases that radiography cannot solve. These additional imaging modalities may result in higher radiation exposure, higher imaging costs, and a delay in diagnosis. Resolve inconclusive X-ray the same day, with the same equipment, in less than 6 minutes. And potentially reduce the need for additional CT or MR exams. 

Make a confident diagnosis at a low dose

  • Up to 95% sensitivity for wrist fracture detection
  • 42% sensitivity for x-ray occult wrist fractures
  • 80% sensitivity for scaphoid fractures, on average
  • Detect wrist fractures with +20 times less dose than a CT exam 

Reduce time-to-diagnosis

  • The exam takes less than 6 minutes and can be performed in the same location, with the same equipment, immediately after an inconclusive X-ray
  • Help decrease the need for additional MRI or CT exams by approximately 50% for suspected hip fractures, when VolumeRAD is coupled with a second clinical examination 

Reduce diagnostic costs

  • An affordable complementary exam that reduces unnecessary exams & frees-up time on your other imaging systems for more demanding cases.

fracture cases that involve hardware.
"What we can get with advanced imaging is an ability to understand our fracture pattern when it's out
of plane. VolumeRAD really does this very well”
“We actually have little signs up reminding us, Don't forget about getting a tomo”

David E. Quinn, M.D.,
Board Certified Orthopedic Surgeon at the
Capital Region Orthopaedics, Albany, NY, discusses
three upper extremity cases.
“As orthopedic surgeons, we’re trying answer some very simple questions especially with respect to
fracture care ... Is there a problem? Does the patient need an operation or is it indicated? Has it been
done properly? Is the problem resolved? I've found that digital tomosynthesis helps answer these questions
in a substantial percentage of cases with minimal risk and minimal expense.”

Lung

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.

It delivers:

  • 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 [2] (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 [1] (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



How it works

How VolumeRAD digital tomosynthesis works

VolumeRAD provides multiple images of the anatomy in a single sweep at a low dose, including chest, abdomen, extremities and spine.

During the sweep, up to 60 ultra-low dose exposures are obtained. Similar to CT exams, the acquired data is then reconstructed into a set of tomographic images (parallel to the detector plane). These images, in DICOM format, can be reviewed sequentially on the acquisition console or on any standard PACS review workstation.

Acquisition sweeps can be performed either at the wall stand or at the table. There are four sweeps available


Wallstand Horizontal Sweep: Horizontal sweep of the tube for supine imaging at the wall stand (requires extended arm and mobile table)



Wallstand Vertical Sweep: Vertical sweep of the tube for upright imaging




 

Table Horizontal Sweep: Horizontal sweep of the tube for
supine imaging



 

Wallstand Cross-table Sweep: Cross-table sweep of the
tube for cross-table imaging at the wall stand
