Required and Preferred Scanner Features for Different Ultrasound Applications
September 2, 2015 | Evaluations & Guidance
Ultrasound is used for a wide variety of clinical applications, each requiring a somewhat different set of sonographic capabilities. A scanner's array of available features is a key factor in determining its appropriateness for a given application. Listed below are common ultrasound applications. For each one, we provide ECRI Institute's recommendations about the necessary transducer types, along with the following:
Imaging abdominal organs is one of the oldest and most common ultrasound procedures. Diagnoses of diseases, cysts, and tumors can be made from the anatomical information—such as size, texture, and location—provided by ultrasound scans. Biopsies of abdominal organs can be performed under ultrasound guidance. Color Doppler imaging (CDI) permits further diagnosis by providing information on blood flow. Comprehensive abdominal studies require a full-featured scanner typically used by experienced (credentialed) sonographers.
Transducer. Sector transducer (convex or vector; adult, 3 to 5 MHz; pediatric, >7 MHz)
Minimum requirements. Real-time 2-D (B-mode) capability, CDI,...
