Ultrasonography01:17

Ultrasonography

4.5K
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...

Computed Tomography

4.5K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Area of Science:

  • Radiology
  • Medical Imaging
  • Oncology

Background:

  • Skeletal metastases from breast and prostate cancer are common.
  • Computed Tomography (CT) is used to monitor bone lesion size.
  • Lesion detection is challenging due to variations in size, shape, and appearance.

Conclusions:

  • The developed automated pipeline shows promise for direct bone lesion detection in CT via proxy segmentation.
  • This is the first known attempt at direct bone lesion detection in CT using this segmentation-based approach.
  • The method facilitates reliable tracking of interval changes in bone metastases.
