Imaging Artifacts
Artifacts can be defined as any structure in an ultrasound image that does not have a corresponding anatomic tissue structure. Artifacts are a common occurrence in an ultrasound display since they are often the result of the physical properties of ultrasound itself. Recognizing artifacts is essential to proper ultrasound interpretation, as not identifying an artifact as such may lead to unwarra...
متن کاملPET/CT imaging artifacts.
The purpose of this paper is to introduce the principles of PET/CT imaging and describe the artifacts associated with it. PET/CT is a new imaging modality that integrates functional (PET) and structural (CT) information into a single scanning session, allowing excellent fusion of the PET and CT images and thus improving lesion localization and interpretation accuracy. Moreover, the CT data can ...
متن کاملArtifacts in Magnetic Resonance Imaging
Artifacts in magnetic resonance imaging and foreign bodies within the patient's body may be confused with a pathology or may reduce the quality of examinations. Radiologists are frequently not informed about the medical history of patients and face postoperative/other images they are not familiar with. A gallery of such images was presented in this manuscript. A truncation artifact in the spina...
متن کاملArtifacts and pitfalls in myocardial perfusion imaging.
Myocardial perfusion imaging (MPI) is an important imaging modality in the management of patients with cardiovascular disease. MPI plays a key role in diagnosing cardiovascular disease, establishing prognosis, assessing the effectiveness of therapy, and evaluating viability. However, MPI is a complex process, subject to a variety of artifacts and pitfalls, which may limit its clinical utility. ...
متن کامل18F-FDG imaging: pitfalls and artifacts.
18F-FDG PET is emerging as a useful tool in the staging and restaging of many malignant neoplasms, such as lymphoma, lung cancer, colorectal cancer, head and neck cancer, breast cancer, and melanoma. To accurately interpret 18F-FDG findings one must be familiar with the normal physiologic distribution of the tracer, frequently encountered physiologic variants, and benign pathologic causes of 18...
