Role of Fluorine 18 Fluorodeoxyglucose Positron Emission Tomography–Computed Tomography in Focal and Generalized Infectious and Inflammatory Disorders

Abstract

"Several advances in imaging have become part of the work-up for localization, diagnosis, and management of infectious diseases and inflammatory disorders. Utility of multiple imaging modalities is a time-consuming step, and significant numbers of patients remain undiagnosed despite utilization of series of tests. Inflammatory cells have avidity for fluorine 18–labeled fluorodeoxyglucose (¹⁸F-FDG), and thus positron emission tomographic–computed tomographic (PET-CT) hybrid imaging provides anatomical and metabolic information that can be used to define the extent of infectious and inflammatory diseases and assess response to treatment. PET-CT provides a “one-stop test” in which use of hybrid imaging provides anatomical and metabolic information. The extent of disease is defined quickly, and response to treatment can be assessed. This modality also helps define the metastatic and/or septic foci where there is lack of localizing symptoms. More recently, there is increasing awareness among clinicians regarding the ability of PET-CT to help in diagnosing, characterizing, and assessing inflammatory disorders. This article reviews the usefulness of this imaging modality."

abstract: Imaging of the gastrointestinal complications of systemic chemotherapy

Abstract:

Gastrointestinal complications of chemotherapy may be serious and potentially life-threatening. Familiarity with and awareness of the potential complications associated with various chemotherapeutic agents/regimens is paramount to enable accurate and timely diagnosis. In this article we review the radiological manifestations of the most notable gastrointestinal complications associated with chemotherapeutic administration.

Conclusion

Figure 1. A 70-year-old woman on day 10 of idorubicin and cytosine arabinoside chemotherapy for acute myeloid leukaemia developed vomiting, abdominal pain, loose bloody stool, and was profoundly neutropenic. Intravenous contrast-enhanced CT demonstrates diffuse colonic mural thickening (black arrow), with surrounding mesenteric stranding (white curved arrow) and ascites (black curved arrow). The distribution is pan-colonic. This constellation of clinical and radiological findings is highly suggestive of neutropenic enterocolitis.
