SCOUT® Radar Localization

The Preferred Localisation Solution From Biopsy to Surgery

The SCOUT system has been clinically demonstrated to drive value and improve patient outcomes. SCOUT is proven to improve radiology workflow and significantly reduce OR delays. Using SCOUT, surgeons can precisely target the affected tissue to pinpoint its location within 1mm, which can mean more successful surgeries, optimised breast conservation strategies, and enhanced outcomes for women.

Features & Benefits

Features and Benefits of Scout Localisation.

  • 85% of Radiologists report a better workflow
  • 97% of Patients who would recommend SCOUT
  • $2,300 cost saving per procedure
  • Shorter day of surgery with decreased patient wait time
  • Less anxiety on day of surgery1
  • Less patient discomfort vs. wires1
  • Potential to eliminate an entire procedure when placed at the time of biopsy
  • May reduce re-excision rates
  • Significantly reduces O.R. start time delays
  • Better oncoplastic procedure for better cosmetic outcomes
  • Feasible and safe to use multiple reflectors for bracketing10
  • Decouples surgery and radiology schedules, making patient scheduling easy
  • Reflector can be placed any time prior to surgery.

Merit Scout Radar Localisation, MRI Detection

Detect

  • After detection, physician and patient can opt to place the Reflector when the biopsy occurs
  • Long-term implant of the Reflector can be placed any time prior to surgery
  • Ultrasound, radiographic and stereotactic guidance options can all be used to place the Reflector

Merit Scout Radar Localisation Reflector size comparison

Localise

  • Reflector remains in place and passive until activated by the SCOUT Guide
  • Can be used to mark soft tissue, including lymph nodes
  • 4mm body size is smaller than a grain of rice
  • Antennas are made of super elastic nitinol alloy, commonly used in medical devices

Merit Scout Radar Localisation Guides Distal Surface Area Comparison

Identify

  • Real-time distance measurement with 60mm detection range
  • 360 ̊ detection with ± 1mm accuracy
  • Documentedreliability of 99.2%
  • Instant response guides dissection path, eliminating guesswork
  • SCOUT Access Guide allows localisation through small incisions

Accuracy

In-depth measurement matters

The SCOUT system’s true distance measurement overcomes challenges with mammography images when estimating tumour depth and location during supine surgical procedures. It allows surgeons to identify the location and depth of the reflector quickly.

Consistency and Predictability

From Clinical Performance

Step 1: Informed Pre-surgical Planning

Merit Scout Radar Localisation informed Pre-surgical Planning precisely identifies tumour location depth
Precisely Identifies Tumor Location & Depth
  • 60mm detection range
  • Permits cosmetically-preferred incision
  • Actual distance measurement allows real-time planning of anterior margin

Step 2: Real-Time Margin Definition During Surgery

Merit Scout Radar Localisation Real-time Margin Definition During Surgery
Helps Optimise Surgical Goals
  • 360˚ detection with ± 1mm accuracy
  • Instant response guides dissection path, eliminating guesswork
  • Predictable specimen with real-time margin definition

Step 3: Accurate Specimen Verification

Merit Scout Radar Localisation Accurate Specimen Verification, optimises breast conservation stragey
Optimises Breast Conservation Strategy
  • Confirms planned surgical margins relative to reflector location
  • Accurate depth measurement when patients are in supine position

Visibility

Excellent under imaging

Clear visibility under imaging

The SCOUT System provides maximum flexibility with visualisation regardless of the imaging modality. Shape provides unique radiographic and ultrasound images, and The Reflector is a clinically insignificant MRI artefact.

Insignificant MRI artefact

SCOUT Radar technology promotes a streamlined Targeted Axillary Dissection, allowing surgeons to identify previously biopsied nodes, even after neoadjuvant chemotherapy, easily.

Wire-free technologies comparison

A study published by Dr. Mary K. Hayes showcases the clarity of the SCOUT Reflector under MRI versus those of two other wire-free technologies on the market.

Clinical Evidence

Feature Study

Use of SCOUT Reflectors to Identify the Previously Biopsied Node Significantly Improves the Probability of Surgical Removal and Subsequently Reduces the False Negative Cancer Rate.

Key results

  • Only 47.4% (9 of 19) biopsied nodes were removed with conventional SLNB
  • False negative rate = 33.3%
  • All (19/19) biopsied nodes were identified and removed with SCOUT
  • False negative rate = 0% (optimal goal).

Additional data and advanced therapy information

  • Foundational Knowledge
  • OR Efficiency
  • Bracketing
  • Long-Term Placement
  • Neoadjuvant Chemotherapy
  • Oncoplastic Techniques
  • Targeted Axillary Dissection
  • Time of Biopsy Placement
  • Outside Breast
