Description and Overview

GE Healthcare’s Signa EXCITE 1.5T HD system is the world’s first 1.5T high definition magnetic resonance (HDMR) system. HDMR provides physicians with improved image clarity.  Exclusive to GE EXCITE systems, HDMR  technology lets you easily diagnose those challenging patients who are the most difficult to examine with conventional MR approaches.

The hardware and software advances in the Signa EXCITE 1.5T HD system provide enhanced clinical and productivity advantages while creating a platform for new techniques and applications. The Signa EXCITE 1.5T HD system delivers a comprehensive applications suite, providing optimal diagnostic capabilities for the assessment of anatomy and function.

GE Healthcare has been the leader in innovative MR technology, introducing the first clinically viable high-field MRI system more than 20 years ago. With over 20 years of 1.5T MR experience, the most 1.5T technology innovations and the largest global 1.5T installed base, GE Healthcare is the only company that can offer a 1.5T system so powerful and proven.

Typical Signa EXCITE 1.5T HD Procedures

• Neurological/brain imaging
• Spine studies
• Orthopedic – including elbow, wrist, hip, knee, foot and ankle
• Prostate
• Pelvis – male and female
• Abdominal
• Specialized vascular and cardiac applications
• Functional and imaging

Patient Benefits

• Patient comfort and easier exam positions
  - features generous 60 cm patient opening and full 48 cm field-of-view

• Reduced rescanning/redundant exams due to patient or organ motion

• Docking table and dual-sided controls for efficiency and patient safety

Physician/Technologist Benefits

• Enhanced imaging techniques enable easier visualization of anomalies, resulting in more diagnostic confidence than ever before;

• High productivity in every aspect of department workflow with true parallel processing and ultra-fast reconstruction;

• User interface common to Signa MR and LightSpeed® CT scanners to facilitate cross-training;

• Ability to offer new and advanced MR procedures – exclusive GE Advanced Applications are offered to simplify the toughest patient cases: LAVA, PROPELLER, VIBRANT
  and MR Echo;

• Benefits of High Definition (HD) Capability in MR Imaging;

• HD gradients deliver high fidelity and high image quality;

• GE Healthcare’s exclusive HD (high definition) coils are optimized for image quality for specific imaging areas and improved patient comfort during the exam.

Benefits of Specialized HDMR Imaging Techniques

• PROPELLER allows for excellent image quality in head studies, consistently even with moving, pediatric, elderly and confused patients. With PROPELLER, physicians can:

  • reduce sensitivity to patient motion and susceptibility artifacts

  • obtain a diagnostic-quality image on almost every scan

  • produce high-definition images despite the often continuous movement of an unsedated child, or on mildly or significantly uncooperative patients.

• VIBRANT (Volume Imaging for Breast AssessmeNT), provides high-definition bilateral breast imaging in one exam. With VIBRANT, physicians can:

  • image both breasts in high resolution in one patient visit

  • perform a bilateral breast exam in both the sagittal and axial planes with the same resolution and scan time as a single-breast MR study

  • obtain high temporal resolution without sacrificing spatial resolution

  • eliminate fat with absolute reliability and confidence for better visualization

  • utilize the bilateral breast imaging technique that is the most sensitive to patients’ diagnostic needs.

Technological Advantages

The Signa EXCITE 1.5T HD system is built with gold-standard components that provide:

• the highest levels of magnetic field homogeneity and stability in the industry;

• open RF architecture with the industry’s largest selection of multi-channel coils optimized for parallel imaging;

• new advanced workstation with true simultaneity for unsurpassed clinical productivity;

• GE EXCITE™ technology, the industry’s first end-to-end redesign of the MRI data pipeline that boosts speed, resolution and SNR far beyond the limits of conventional MRI scanners.
