F-18 FDG PET/CT Imaging in Normal Variants, Pitfalls and Artifacts in the Abdomen and Pelvis

Artifacts, Pitfalls and Normal Variants

Image artifacts are encountered daily in clinical ultrasonography and may be a source of confusion for the interpreting sonologist. The understanding of the mechanisms behind their production allows recognition of artifacts and avoids misinterpretations and incorrect diagnoses. Some artifacts may be avoidable and arise secondary to improper scanning technique. Other artifacts are generated by t...

Lumbar spine imaging. Normal variants, imaging pitfalls, and artifacts.

Accurate recognition and reporting of spine abnormalities on MRI requires knowledge of normal anatomy and its variants. This article deals with common normal variants, points out pitfalls which may be sources of errors in interpretation and describes imaging artifacts which are essential to be recognized and not mistaken for true pathologies.

18F-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...

F 18 FDG PETCT detection for liver metastases

Imaging infection and inflammation in children with (18)F-FDG PET and (18)F-FDG PET/CT.

The goal of this article is to delineate indications for (18)F-FDG PET/CT pertaining to inflammation in the pediatric population, with emphasis on those that have been described in the literature. The limitations of (18)F-FDG PET/CT in this type of evaluation are also described, and the importance of using as low a dose as feasible is discussed. After reading this article, the reader should be ...
