Sierra NMUS1

Sierra NMUS1 Ultrasound

Complement your electrodiagnostic testing with Sierra NMUS1 Ultrasound

Sierra NMUS1™ is an advanced ultrasound imaging tool designed specifically for neuromuscular diagnostics, musculoskeletal examinations, and augmented needle guidance. Sierra NMUS1 and the NMUS+ protocol in Sierra® software provide innovative and sophisticated algorithms and dedicated imaging and diagnostic features.

Sierra NMUS1 is completely integrated into the Sierra software NMUS+ protocol for fast and accurate diagnoses, enabling high image quality, an intuitive protocol-specific user-interface, a simple integrated workflow and results, and muscle quantification mode.

With Sierra NMUS1, you can:

  • Instantly transition from NCS or EMG testing to imaging.
  • Utilize combined protocols with improved image quality, integrated measurements, and tissue quantification to increase diagnostic accuracy and reduce examination time.
  • Combine all results into a single report to clearly communicate findings.

Sierra NMUS1 is a powerful option for point-of-care imaging during neurodiagnostic examinations.

Ultrasound Probes for Sierra NMUS1

Three interchangeable handheld probes (transducers) are available for use with Sierra NMUS1.

  • Linear Ultrasound Probes are used to create high resolution images of superficial structures near the body surface, like vascular imaging, and are also called vascular probes. Linear probes are often used to measure movement in a linear fashion, i.e. scanning along a nerve. Different linear transducers are able to measure different movements.
  • Linear Ultrasound (Vascular) Probes are used to create high-resolution images of superficial structures near the body surface.
  • Curvilinear Ultrasound Probes: Curvilinear – or convex – ultrasound probes use lower frequencies for deeper penetration and wider depth of field for viewing larger muscles and deeper structures.

Whitepaper: The Case for Neuromuscular Ultrasound

Cadwell Whitepaper: The Case for Neuromuscular Ultrasound

Recent developments in high-frequency ultrasound imaging technology have resulted in neuromuscular ultrasound (NMUS) becoming another important component of neurodiagnostic evaluations. Ultrasound can help diagnose common entrapment neuropathies and localize other nerve problems. Combined with EMG or NCS, you can increase your diagnostic certainty quickly, safely, and without patient discomfort.
