Routine helical CT of the abdomen: image quality considerations.

Abstract

Helical CT scanning should be the preferred means of acquiring routine abdominal CT images.

Intraductal Papillary Mucinous Tumors of the Pancreas

“…Cystic lesions were seen in 25 patients (92.6%). Helical CT offers some advantages compared with conventional CT. For example, images of the entire pancreas can be obtained during a single breath-hold with a slice thicknesses of 3-5 mm with excellent resolution of fine details such as the pancreatic duct [20]. The cystic lesion was unilocular in five patients (18.5%) and multilocular with a lobulated margin in 20 patients (74%).…”

Diagnostic Performance of Imaging in Detection and Characterization of Liver Lesions

“…In our study we used the spiral computed tomography (CT) because it has gained approval as the favorite CT technique for routine liver evaluation because it provides image acquisition at peak enhancement of the liver parenchyma [29][30][31][32]. In addition, the fast data acquisition allows successive scanning of the entire liver at different moments after injection of contrast material, thus creating the possibility of multiphasic liver CT.…”

Three‐Dimensional Imaging of the Speaking Shunt in Patients With Near‐Total Laryngectomy

“…To date, spiral CT has been used to obtain 3‐D imaging of different structures 11–15 and to evaluate neoplastic masses in the upper airway, lungs, liver, and other organs, since rapid scanning with 1‐second scan time and no interscan delay provides high levels of contrast. To the best of our knowledge, the 3–D imaging model of the dynamic speaking shunt in near‐total laryngectomy patients has not been previously reported in English literature.…”
