The major vendors also highlighted various software enhancements and applications solutions at this year’s RSNA.
Fusion imaging for needle-guided biopsies has been a feature available for many years, but earlier versions could be difficult and time-consuming to utilize, and prone to errors during the alignment process. The newer technology exhibited allows for the real-time fusion of images and instrument navigation capabilities to provide guidance during tissue biopsies and ablation procedures.

Another software enhancement that was highlighted was shear wave elastography. Shear wave elastography is a noninvasive and inexpensive procedure used to assess liver and breast lesions without an invasive biopsy. Ultrasound elastography technology has also been used for a number of years to obtain information concerning the elasticity of soft tissue; however shear wave elastography (transient elastography) provides more accurate, quantitative information concerning the stiffness of the tissue.
CT/MRI
The new Signa Architect 3T, Signa Voyager 1.5T, and Signa Artist 1.5t were a part of the new offerings from GE. Also on the MRI side of the booth was the Signa Premier, a work-in-progress collaboration with the National Football League.
In the CT portion of the booth GE highlighted its Revolution line of CT scanners with a new GSI detector that allows the user to perform spectral imaging. Toshiba showcased its new Galan 3T MRI and the new Aquilion Genesis 320 detector Premium CT system. Siemens launched the Magnetom Sempra 1.5T MRI system, and had three new offerings in the CT market as well. The new models include the Somatom Drive premium dual source system and the Somatom Go.Now 16- and 32-slice systems.
SwissRay has entered the MRI field with the SR Pulse 710. Hitachi and Philips debuted their current systems offerings. One of the big trends seen this year is the adaptation of all vendors offering five-minute MRI brain scans and faster scanning in other body parts. Many vendors are also offering software that can reformat a single MRI acquisition reconstructed into five sequences.
Interventional X-ray (IXR)
Several new systems were introduced, including Siemens’ Artis zeego Pheno, an updated version of its already unique Artis zeego robotic c-arm, as well as Toshiba’s Infinix-i Sky with a new concept of a double-slide c-arm design. Philips continued to tout its AlluraClarity line of imaging solutions as did GE with its unique laser-guided in-room mobile Discovery IGS 700 series. Shimadzu Trinias’ series of floor- and ceiling-mounted solutions rounded out the hardware that was being shown and highlighted.
