Is Sucralose Ingestion Acceptable Before 18F-FDG PET/CT Imaging?

FDG PETCT in colorectal cancer

Colorectal cancer represents the second most common malignancy worldwide, with approximately one million newly diagnosed cases each year, and is the fourth leading cause of cancer mortality. This article provides an overview of the role of FDG (fluorodeoxyglucose) PET (positron emission tomography) CT (computed tomography) for assessment in patients with colorectal cancer. A summary of key lear...

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...

Inflammation and infection: imaging properties of 18F-FDG-labeled white blood cells versus 18F-FDG.

UNLABELLED (18)F-FDG and (18)F-FDG-labeled white blood cells ((18)F-FDG-WBCs) are valuable radiopharmaceuticals for imaging focal sites of inflammation and infection. In the present study, the imaging properties of both radiotracers were compared in sterile and septic inflammation models. METHODS Groups of adult male Sprague-Dawley rats (100-120 g) were injected in the left posterior thigh mu...

Influence of bowel preparation before 18F-FDG PET/CT on physiologic 18F-FDG activity in the intestine.

UNLABELLED Our objective was to investigate the use of bowel preparation before (18)F-FDG PET/CT to reduce intestinal (18)F-FDG uptake. METHODS Sixty-five patients with abdominal neoplasias were assigned either to a bowel-preparation group (n = 26) or to a native group (n = 39). (18)F-FDG activity was measured in the small intestine and the colon. RESULTS In the 26 patients with bowel prepa...
