Esaote S-Scan

The Esaote S-Scan is a total musculoskeletal (MSK) 0.25T permanent magnet MRI system designed to cover both upper/lower extremity joints and full spine imaging (L-spine and C-spine). Built specifically for orthopedic practices, sports medicine clinics, and outpatient imaging centers, the S-Scan combines an open C-arm geometry with an ergonomic, rotating patient table to deliver claustrophobia-free exams with low operating costs. Operating on standard single-phase wall power ($110\text{V}/220\text{V}$) with zero liquid helium requirements, it provides a complete in-office imaging suite with minimal facility modification.

Description

Overview

The Esaote S-Scan represents a major leap in dedicated musculoskeletal MRI. It bridges the gap between limited limb-only scanners and costly whole-body MRI systems. Engineered with an asymmetric rotating table and a wide open C-shaped magnet, the S-Scan provides easy patient positioning and immediate target centering for all MSK examinations—from subtle scaphoid fractures in the wrist to disc herniation in the lumbar spine.

Designed for extreme operational efficiency, the S-Scan runs on standard commercial power, requires no liquid nitrogen or helium refilling, and fits inside a single room without requiring structural floor reinforcement or massive chilling equipment.

Key Features & Advanced Technologies

  • Expanded Clinical Scope (MSK + Spine): Specifically tuned hardware and specialized sequence protocols allow comprehensive evaluation of the cervical and lumbar spine, shoulders, hips, and all distal extremities.

  • Asymmetric Rotating Patient Table: Simplifies positioning for both pediatric and bariatric patients. The table rotates to align the target anatomical region precisely with the magnet’s sweet spot.

  • eXP Speed & Quality Enhancements: Features Esaote’s proprietary signal processing and acceleration algorithms (SpeedUp and TR reduction), enabling up to $35\%$ faster scan times with sharp image contrast.

  • Real-Time Positioning Console: Gantry display allows fast scout positioning directly at magnet side, streamlining technologist workflow and accelerating throughput.

  • Helium-Free Permanent Magnet: Maintains consistent magnetic stability without cryogen boil-off risks, quench pipes, or expensive routine maintenance.

  • Independent RF Pavilion Shielding: Compatible with modular lightweight RF shielding enclosures that eliminate the need for heavy, permanent wall construction during installation.
