Apr 7, 2016 · Motion artifacts are caused by patient breathing and pulling. Positioning artifacts such as belly fold (Fig. 38.2 ), pectoral muscle fold (Fig. 38.3 ), hand artifact (Fig. 38.4 ), chin artifact (Fig. 38.5 ), and skinfold artifact (Fig. 38.6a–c) are more common phenomenon in the geriatric age group.
Jul 31, 2018 · Artifacts in digital breast tomosynthesis and synthesized 2D imaging can obscure important findings on mammograms. The radiologist, mammography technologist, and medical physicist must be able to recognize these artifacts and use the vendor's new processing algorithms to mitigate the effects of such artifacts.
Feb 15, 2019 · Artifacts related to DBT include blurring-ripple, truncation, and loss of skin and superficial tissue resolution. Motion artifacts are difficult to recognize because of inherent out-of-plane blurring.
Artifacts in mammography: ways to identify and overcome them. Chaloeykitti L, Muttarak M, Ng K H. ABSTRACT. High-quality mammography images enhance a radiologist’s ability to interpret mammograms because they have greater sensitivity and specificity. Artifacts may create pseudo-lesions or mask abnormalities leading to misinterpretation.
Oct 4, 2023 · Contrast-enhanced mammography (CEM) involves addition of intravenous iodinated contrast material at digital mammography, thus increasing the ability to detect breast cancer owing to tumor contrast enhancement.
Nov 1, 2008 · Commonly encountered artifacts include patient-related artifacts (motion artifact, antiperspirant artifact, thin breast artifact), hardware-related artifacts (field inhomogeneity, detector-associated artifacts, collimator misalignment, underexposure, grid lines, grid misplacement, vibration artifact), and software processing artifacts ...
Nov 20, 2012 · Artifacts reduce the quality of mammograms and may mimic or obscure abnormalities and cause interpretation errors. Recognizing artifacts improves the quality of mammographic interpretation and prevents the characterization of artifacts as breast disease.
