Ultrasonography01:17

Ultrasonography

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

Area of Science:

  • Medical Imaging
  • Radiology
  • Ultrasound Technology

Background:

  • Breast biopsy markers are crucial for localizing tissue for subsequent surgical excision.
  • Assessing the visibility of these markers using ultrasound's color Doppler twinkling is essential for clinical practice.

Purpose of the Study:

  • To evaluate the color Doppler twinkling strength of 37 breast biopsy markers.
  • To compare the performance of two ultrasound systems (GE LOGIQ E9 and E10) and various transducers.
  • To determine if newer ultrasound technology offers sufficient twinkling for clinical utility.

Main Methods:

  • Thirty-seven breast biopsy markers were embedded in gelatin phantoms.
  • Imaging was performed using two ultrasound platforms and multiple transducers.
  • Two radiologists independently scored twinkling strength on a 0-4 scale, with scores >=3 considered actionable.

Main Results:

  • Fourteen markers showed measurable twinkling; newer systems (E10) yielded higher, actionable scores compared to older systems (E9).
  • System generation and transducer type significantly impacted twinkling strength, with the L8-18i transducer showing marked improvement on the E10.
  • A polymethyl methacrylate (PMMA) research marker exhibited consistently high and reproducible twinkling across both systems.

Conclusions:

  • Ultrasound system generation, transducer selection, and acquisition parameters critically influence the color Doppler twinkling of breast biopsy markers.
  • Newer ultrasound technology demonstrates potential for improved marker visualization, aiding in clinical decision-making.
