Article Synopsis
- Bowel gas often disrupts the clarity of abdominal ultrasonography (AUS), leading to the common practice of scheduling AUS before esophagogastroduodenoscopy (EGD).
- This study tested whether using carbon dioxide (CO2) during EGD affects the quality of subsequent AUS, evaluating image quality through a non-inferiority test with 30 participants.
- Results showed no significant deterioration in AUS image quality after CO2 insufflation during EGD, suggesting that performing EGD first could optimize scheduling and efficiency for clinical exams.
Objectives: This study was conducted in order to identify imaging features on three-dimensional computed tomography (CT) of unexplained chronic cough (UCC) patients with positive sputum cultures for filamentous Basidiomycetes (f-BM).
Methods: UCC outpatients who had been given various questionnaires for cough, pulmonary function tests, and fungal cultures of sputum were evaluated. Multidetector row CT (MDCT) was performed for three-dimensional CT analysis of the lungs.
Introduction: S-methyl-(11)C-labeled l- and d-methionine ((11)C-l- and d-MET) are useful as radiotracers for tumor imaging. However, it is not known whether the transport mechanism of (11)C-d-MET is the same as that for (11)C-l-MET, which is transported by the amino acid transport system L. In this study, we investigated the transport mechanism of (11)C-l- and d-MET by analyzing the expression of transport system genes in human-derived tumor cells.
