Reprint requests to: Dr. Chen-Pin Chou Department of Radiology, Kaohsiung Veterans General Hospital. No. 386, Ta Chung 1st Road, Kaohsiung 813, Taiwan, R.O.C. A 47-year-old woman presented to our hospital with chief complaints of hematuria and left flank pain. The patient denied any recent history of trauma, renal surgery or urinary tract disease. Arterial-phase CT and three-dimensional CT angi...

This article describes a quantitative evaluation of visualizing small vessels using several image reconstruction methods in computed tomography. Simulated vessels with diameters of 1-6 mm made by 3D printer was scanned using 320-row detector computed tomography (CT). Hybrid iterative reconstruction (hybrid IR) and model-based iterative reconstruction (MBIR) were performed for the image reconstr...

The number of CT images increased significantly when 16-row multi-detector CT scanners (MDCT) were introduced. The purpose of this study is to quantify the total data management cost of MDCTand to identify cost drivers. An activity-based costing (ABC) method was used to analyze cost drivers in MDCT data management. Changing from 4-row to 16-row CT, mean image count per exam was increased from 6...

A total of 79 patients with biopsy proven primary adenocarcinoma of the rectum who were referred for thoracic and abdominal CT staging were enrolled in this study. The contrast-enhanced MDCT scans were performed both on a 256 row scanner (ICT, Philips) and on 16 row scanner (Brilliance 16P, Philips) with the following acquisition parameters: tube voltage 120 KV and tube current 150-300 mAs (dep...

The recent proliferation of multi–detector row computed tomography (CT) has led to an increase in the creation and interpretation of images in planes other than the traditional axial plane. Powerful three-dimensional (3D) applications improve the utility of detailed CT data but also create confusion among radiologists, technologists, and referring clinicians when trying to describe a particular...
