TOMOSYNTHESIS Meaning and
Definition
-
Tomosynthesis is a medical imaging technique that combines elements of conventional X-ray technology with computed tomography (CT) scanning to create a three-dimensional (3D) representation of anatomical structures within the body. This technique is primarily used in the field of mammography for breast examinations, but it can also be applied to other parts of the body.
Tomosynthesis works by capturing a series of X-ray images from different angles around the target area. These images are then digitally reconstructed using specialized software to create a 3D image, allowing the radiologist to view the breast tissue layer by layer. This approach helps to minimize the overlapping of breast tissue, providing a clearer view of any abnormal lesions or tumors that may be present.
Compared to traditional two-dimensional (2D) mammography, tomosynthesis offers several advantages. Firstly, it reduces the chance of false positives and false negatives, as it enables a more accurate visualization of breast tissue. Additionally, tomosynthesis enhances the detection of small, early-stage breast cancers that may not be clearly visible in 2D images. This can lead to earlier diagnosis and potentially improved outcomes for patients.
Tomosynthesis is considered a less invasive and lower radiation dose technique than CT scans or traditional mammograms. It is typically performed in conjunction with regular mammography as part of routine breast cancer screening for women, particularly those with dense breast tissue.
Overall, tomosynthesis is a valuable imaging tool that provides clinicians with a more detailed examination of breast tissue, helping to improve early detection and diagnosis of breast cancer.

Etymology of TOMOSYNTHESIS
The word "tomosynthesis" is derived from two Greek roots: "tomo" (τόμος) and "synthesis" (σύνθεση).
- "Tomo" (τόμος) means "to cut" or "a section" in Greek. It comes from the verb "temnein" (τέμνειν), which means "to cut". This root is often used in medical terms to indicate a cutting or sectioning process.
- "Synthesis" (σύνθεση) means "putting together" or "combination". It comes from the verb "synthénein" (συνθέναι), which means "to bring together" or "to combine".
