SIGNA Artist is a premium 1.5T wide-bore MRI system from GE HealthCare designed to provide a balance of high image quality, patient comfort, workflow efficiency and long-term upgradeability. The platform combines Total Digital Imaging, up to 128 RF channels, AIR Coils, AIR Recon DL and advanced workflow technologies for consistent imaging across a broad range of clinical applications.

Key Features

• 1.5T Wide-Bore Design: Provides a spacious patient environment and supports feet-first imaging, helping accommodate a wide range of patient sizes and improve comfort.
• Up to 128 RF Channels: SIGNA Artist’s Total Digital Imaging (TDI) architecture digitizes individual RF-channel inputs and is designed to improve SNR and image uniformity. GE reports up to 25% higher SNR.
• AIR Coils: Flexible, lightweight coils provide 360° adaptive coverage, helping simplify positioning while maintaining high-quality images.
• AIR Recon DL: GE’s deep-learning reconstruction technology improves image sharpness and SNR while reducing noise. GE states that it can enable images to be produced up to 50% faster in the relevant comparison.
• AIR Touch: Automatically selects the appropriate coil elements and configuration, helping simplify setup and improve consistency.
• Advanced Cardiac Imaging: Supports advanced cardiac applications including imaging with AIR MP Coil, wireless gating and Sonic DL.
• Free-Breathing Imaging: Advanced technologies support examinations for patients who may have difficulty performing breath-holds.
• Feet-First Imaging: Provides an alternative positioning approach that can improve patient acceptance and reduce claustrophobia.
• Low-Helium Magnet Technology: GE’s magnet technology is designed to reduce helium consumption by up to 70% over its lifecycle compared with conventional designs.
• Scalable Platform: SIGNA Artist can be upgraded through GE HealthCare’s SIGNA Evo and SIGNA Continuum programs, extending the useful life of the system.

Patient Experience

SIGNA Artist was designed with patient comfort as a major consideration. Its wide-bore configuration, feet-first imaging capability and flexible AIR Coils provide greater accessibility and positioning flexibility.

GE reports that AIR Coils can help reduce patient setup time by 59% and patient table time by 37% in its stated comparisons.

Workflow & Productivity

The system integrates multiple technologies intended to simplify the examination from positioning through image reconstruction:

AIR Coils → AIR Touch → automated workflow → AIR Recon DL

This combination can reduce manual coil selection and positioning, improve examination consistency and shorten scan times. GE positions SIGNA Artist as a system designed to reduce both technologist workload and radiologist reading fatigue while maintaining consistent image quality.

Clinical Applications

SIGNA Artist is a versatile whole-body MRI platform suitable for:

• Neurology
• Cardiology
• Oncology
• Musculoskeletal / Orthopedics
• Spine
• Abdominal and body MRI
• Breast imaging
• Women’s health
• Fetal imaging

GE’s official clinical examples include cardiac MRI, 4D ViosWorks, fetal imaging, 3D Cube T2 and MRCP with AIR Recon DL.

Upgradeability

A significant advantage of SIGNA Artist is its scalable architecture. GE HealthCare offers the SIGNA Artist Evopathway, which can transform existing 1.5T systems by expanding the bore to 70 cm, adding advanced AI capabilities and improving patient accessibility without replacing the entire MRI platform.
