Spiral computed tomography for biliary dilatation

Journal of Pediatric Surgery, 1995
Spiral computed tomography (SCT), which consists of rapid volumetric data acquisition and planar image display, was performed on 12 patients with biliary dilatation after excisional procedure. The technique was evaluated for image quality and impact on clinical practice. All patients safely underwent SCT scanning after intravenous cholangiography (IVC)

Optimal pitch in spiral computed tomography

Medical Physics, 1997
The focus of this paper is to analytically optimize spiral/helical computed tomography (CT) protocols based on a simplified imaging model. Spiral CT was approximately modeled as follows: Using the half‐scan raw data interpolation method, the variance of the spiral CT slice sensitivity profile is equal to the sum of squared detector collimation divided ...

Spiral Computed Tomography

2017
X-ray computed tomography (CT) is a medical imaging method, where the patient is placed on the CT table and an x-ray tube rotates around the body and sends x-rays through the body. Those x-rays experience a varying attenuation along their way depending on the body part they are transversing.

Predicting Postoperative FEV1 Using Spiral Computed Tomography

Academic Radiology, 2010
Lung resection for primary bronchogenic carcinoma in the setting of chronic obstructive pulmonary disease often requires a detailed assessment of lung function to avoid perioperative complications and long-term disability. The aim of this study was to test the hypothesis that a novel technique of spiral computed tomographic (CT) subtraction imaging ...

Spiral computed tomography for bilioenteric anastomotic stricture

Pediatric Surgery International, 1998
Spiral computed tomography scanning after intravenous cholangiography (IVC-SCT) was used to assess the anatomy of the biliary tree and anastomosis in a 7-year-old girl with recurrent cholangitis 5 years after surgical excision of a choledochal cyst.
