This video demonstrates the radiofrequency echographic multi-spectrometry (REMS) technique for assessing bone mineral density (BMD). The patient is positioned supine, and ultrasound gel is applied to the femoral neck, a fracture-prone site in the femur. The probe then emits ultrasound waves, which reflect off the bone tissue at a speed influenced by BMD. The probe captures these reflected waves, enabling the quantification of BMD.

Protocol

1. System preparation

NOTE: The system (EchoStation in the Table of Materials) is composed of a touch screen monitor, a main unit, and a 3.5 MHz ultrasound convex probe.

1. Switch on the monitor by pressing the power button on the top left edge of the unit. The operation will take a few seconds.
2. Tap the icon of the software at the top right of the screen
3. Insert the user identifier and password, then tap the Start button  
4. Switch on the main unit by pressing the power button on the device

2. Subject preparation
