Ultrasonography

4.4K
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.
During an ultrasonography procedure, a handheld device called...

Area of Science:

  • Medical Imaging
  • Ultrasound Technology
  • Radiology

Background:

  • Interoperator variability in handheld ultrasound (HHUS) affects breast lesion reproducibility.
  • Accurate localization of breast masses is crucial for effective clinical management.

Purpose of the Study:

  • To analyze features influencing breast mass position differences during HHUS.
  • To evaluate the impact of a computer-assisted scanning device (DEVICE) on localization precision and annotation time.

Main Methods:

  • Prospective study of 34 small breast masses in 28 patients.
  • Two operators performed manual and automated annotations.
  • Logistic regression models analyzed mass displacement features during DEVICE-guided scanning.

Main Results:

  • Computer-assisted scanning improved interoperator localization precision to 6.6 ± 2.8 mm from 19.9 ± 16.1 mm (manual).
  • Annotation and reidentification times were reduced by 33 s and 46 s, respectively.
  • Logistic regression models accurately discriminated small from large mass displacements (AUC 0.78–0.82).

Conclusions:

  • Computer-assisted HHUS enhances breast mass location reproducibility.
  • The DEVICE improves exam efficiency by controlling operator-actionable features.
  • This technology offers a significant advancement in breast lesion assessment.
