Helical Computed Tomography for Abdominal Imaging
World Journal of Surgery, 1996AbstractSignificant technologic advances have taken place in computed tomography (CT). Current‐generation conventional CT scanners are able to image a slice of tissue in as little as 2 to 3 seconds and can acquire several consecutive images. Although it is a substantial improvement from the CT of 5 years ago, there remain practical limits to the ...

Helical computed tomography of renal lesions
Current Opinion in Urology, 1999Helical computed tomography is a new technique that acquires a volumetric data set of both kidneys within a single breath-hold. It has proved to be superior to conventional computed tomography. Multiphasic helical computed tomography after the administration of contrast material shows advantages concerning the detection and characterization of renal ...

Bronchial arterial imaging using helical computed tomography
Pulmonary Pharmacology & Therapeutics, 2007The bronchial arteries, which provide the systemic arterial supply to the lungs, are involved in a variety of disease processes in humans, including congenital disorders, infection, and pulmonary thromboembolism. In these conditions, the bronchial arteries hypertrophy and bronchial blood flow increases.

Liver Imaging with Multidetector Helical Computed Tomography
Journal of Computer Assisted Tomography, 2003The speed and flexibility of multidetector computed tomography (MDCT) have led to improvements in liver imaging, particularly related to the detection and characterization of focal lesions. This report discusses the different phase of liver enhancement following the bolus administration of iodinated contrast material, and the enhancement pattern of ...

Tracheal agenesis: evaluation by helical computed tomography
Pediatric Radiology, 2000We present a newborn infant with type II tracheal agenesis. Helical CT was performed and confirmed the diagnosis. Retrospective coronal and sagittal multiplanar reconstructions clearly demonstrated the complex anatomy of the malformation. The absence of a significant portion of healthy trachea did not present any possibility for surgical correction.

Pancreatic Carcinoma: Applications for Helical Computed Tomography
Endoscopy, 1997Helical computed tomography (CT) represents a significant technical improvement over conventional (incremental) CT. This noninvasive imaging technique is now routinely used in the evaluation of patients with suspected pancreatic cancer. This paper focuses on the topics of CT technique (scanning parameters, use of intravenous contrast media, use of oral

Helical Computed Tomography of Bowel and Mesenteric Injuries
The Journal of Trauma: Injury, Infection and Critical Care, 2001The role of computed tomography in diagnosing hollow viscus injury after blunt abdominal trauma remains controversial, with previous studies reporting both high accuracy and poor results. This study was performed to determine the diagnostic accuracy of helical computed tomography in detecting bowel and mesenteric injuries after blunt abdominal trauma ...

Despite the widespread use of percutaneous endoscopic gastrostomy (PEG) tubes, their placement may be associated with a variety of complications, including gastrocolic fistula.In total, 48 individuals underwent computed tomography-gastro-colonography (CT-GC)-guided PEG placement.

European Radiology, 2005
Our aim was to compare the quality of pelvicalyceal visualization on computed tomography (CT) urography using a small intravenous contrast material dose, hydration, and high-resolution multidetector CT (MDCT) with that of conventional helical CT. The test (MDCT) group (49 consecutive patients, 98 kidneys) was scanned 5 min following an intravenous ...
