To assess the clinical benefit of 18F-Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography (18F-FDG-PET/CT) in evaluating pelvic lymph nodes in patients with early stage cervical cancer (FIGO stage 1a–1b1), who have magnetic resonance imaging (MRI)-defined lymph node negative disease, with histopathologic results as the reference standard. ⋯ Pathologic validation of 18F-FDG-PET/CT imaging demonstrates little value for 18F-FDG-PET/CT in patients with early stage (FIGO stage 1a–1b1) MRI-defined lymph node negative cervical carcinoma. Since the likelihood of metastatic nodal disease is very low in women with stage 1a–1b1 cervical cancer, we believe that 18F-FDG-PET/CT should not have a role in the routine pre-treatment evaluation of these women.

To determine if transit time for excretion of gadoxetate into major bile ducts and duodenum correlates with clinical models of hepatocellular function. ⋯ The transit time for gadoxetate to appear in extrahepatic duct is a reasonable indicator of liver function, and may be included in radiology reports. The appearance in the duodenum, however, may depend on factors other than liver function, such as the physiology of the gallbladder and sphincter of Oddi.
