Introducing Discovery* IQ
Image Quality. Intelligent Quantitation.

Healthcare providers require great image quality and consistent quantitation. You cannot be expected to prioritize one of these before the other. Complete information is required. Critical information your patients depend upon every day.

GE Healthcare’s latest PET/CT innovation delivers both excellent image quality and consistent quantitation, without compromise. Discovery IQ is equipped to provide what you need to help with your primary mission – delivering the best possible patient outcomes.

NEW PET Detector

The NEW GE LightBurst PET detector technology delivers the highest sensitivity1 of any PET/CT anywhere enabling excellent image quality with fast scans at low doses for greater patient comfort and care.

GE Healthcare Discovery IQ PET Detector

Highest NEMA Sensitivity in the Industry1

  • Provides up to 22 cps/kBq
  • Enables very fast acquisition times
  • Allows for low dose scans 
  • Can image with both 1/2 the PET dose and 1/2 the scan time2
  • Delivers outstanding image quality for small lesion detectability

Largest Axial Field-of-View Coverage in the Industry1

  • Provides up to 26 cm of coverage
  • Enables scanning in the fewest possible bed positions
  • Scans full organ, such as thorax respiratory MotionFree study as fast as 4 minutes 
  • Allows for greater throughput/workflow efficiencies for your clinic

Highest Clinical Noise-Equivalent-Count-Rate (NECR) for clinical 18F acquisition in the Industry1

  • Optimized for oncology practices administering 18F as done in 94% of procedures3 
  • Up to 75 kcps @ 2.4 kBq/mL4 
  • Delivers high NECR for both low- and high-count rate radioisotopes such as 68Ga, 11C, 82Rb and more

Fast Electronics with Dual Acquisition Channels 

  • Delivers high quantitative accuracy, post NECR peak, even with high-count rate radioisotopes (e.g., 82Rb) where noise typically has a negative impact
  • +/- 3.5% up to 22 kBq/mL

NEW PET Reconstruction

For the first time in PET reconstruction, no trade-off between excellent image quality and consistent, quantitative SUV measurements to assist in earlier determination of how well your treatment plan is working.

Q.Clear, pioneering full-convergence reconstruction technology, enables fast and efficient reading for greater confidence in evaluating a patient’s response to treatment. It provides up to 2x improvement in both PET quantitation accuracy (SUVmean) and image quality (SNR).

NEW System Design

Discovery* IQ, built as a mobile-ready PET/CT platform, features a NEW system design featuring a scalable PET detector ring and GE’s Optima* CT540.

This system is designed to be the most adaptable and accessible PET/CT scanner anywhere enabling improved healthcare for more people in more places.

GE Healthcare Discovery IQ

Scalable PET Detector Ring

Built to optimize clinical performance 

  • Delivering technologies to help you with your everyday mission – providing the best possible patient outcomes

Investment protection 

  • Built for today, ready for tomorrow with the Discovery IQ upgradable platform that grows with your department needs

Versatile platform

  • Provides solutions for all clinical environments from the first-time PET/CT user to high-volume and clinical research departments

Mobile-ready platform

Providing greater access to more patients in more places

  • Opportunity for imaging departments to gradually expand clinical services

Optima CT540

Excellent signal management

  • Outstanding image quality in signal starved areas (shoulder, hip, large patients, metal)

Coverage and speed

  • 20 mm coverage for fast exams and short breath-holds

Low dose and fast scanning 

  • ASiR* reconstruction1
  • 50-slice equivalent CT speed with IQE2 1.75 pitch booster 
  • 0.5-second rotation speed

1. ASiR is an optional feature in the Discovery IQ. In clinical practice, the use of ASiR may reduce CT patient dose depending on the clinical task, patient size, anatomical location and clinical practice. A consultation with a radiologist and a physicist should be made to determine the appropriate dose to obtain diagnostic image quality for the particular clinical task.
2. Image quality as defined by an Artifact Index in Phantom testing.

Clinical Impact


The first global installation of Discovery IQ took place at the Institut Universitaire du Cancer de Toulouse in Toulouse, France. This video features comments from Prof. Frédéric Courbon, Ph.D., M.D. about his initial positive reactions to the capabilities of Discovery IQ and how he sees it impacting the care this facility can provide to patients.
