Imaging Artifacts on Synthesized Mammogram: What a Radiologist should Know!

Area of Science:

• Radiology
• Medical Imaging

Background:

• Synthesized mammography (s2D) reconstructs 2D images from tomosynthesis data, offering reduced radiation exposure compared to standard 2D mammography.
• The back-projection reconstruction technique used in s2D imaging results in a distinct image appearance compared to conventional mammograms.
• As a relatively new technology, s2D mammography presents a learning curve for interpretation.

Purpose of the Study:

• To provide a pictorial review of common artifacts encountered in synthesized mammography (s2D) images.
• To enhance awareness among radiologists and technicians regarding potential interpretation challenges posed by s2D artifacts.
• To improve the diagnostic accuracy and efficiency of interpreting synthesized mammograms.

Main Methods:

• This is a pictorial review focusing on common artifacts in synthesized mammography.
• The review highlights artifacts encountered during the interpretation of s2D images.
• The content is aimed at educating new radiologists and technicians.

Main Results:

• Synthesized mammography utilizes reconstruction techniques that differ from standard 2D mammography.
• Common artifacts can arise during the reconstruction process, potentially impacting image interpretation.
• Awareness of these artifacts is crucial for accurate diagnosis.

Conclusions:

• Synthesized mammography offers benefits like reduced radiation exposure.
• Understanding and identifying artifacts in s2D images is essential for accurate interpretation.
• This review serves as a guide to common artifacts, aiding radiologists and technicians in their practice.
