The Identification of Mandible Fractures by Helical Computed Tomography and Panorex Tomography

Journal of Craniofacial Surgery, 2005
The introduction of computed tomography (CT) in 1972 revolutionized the radiographic evaluation of patients who have experienced trauma. However, panoramic tomography (PT) continued to be superior in sensitivity to CT in the identification of mandible fractures and has been considered the gold standard for the past 3 decades.

A 2π interpolative algorithm for helical computed tomography

Proceedings., International Conference on Image Processing, 2002
The projection set in a helical computed tomography scan is inherently incomplete and inconsistent. This is caused by the constant patient translation during the data acquisition process. We present an interpolative algorithm using the projections acquired within 2/spl pi/ view angle.

Multidetector helical computed tomography of the liver

Academic Radiology, 2004
Abstract Rationale and objectives The purpose of this study was to compare hepatic enhancement characteristics using two different contrast media injection protocols with multidetector helical computed tomography. Materials and methods Twenty-three patients with known or suspected liver lesions scheduled to undergo biphasic hepatic multidetector

Computed tomography-gastro-colonography for percutaneous endoscopic gastrostomy using a helical computed tomography

The American Journal of Surgery, 2015
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.

Improved pelvicalyceal visualization with multidetector computed tomography urography; comparison with helical computed tomography

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 ...

Bronchial arterial imaging using helical computed tomography

Pulmonary Pharmacology & Therapeutics, 2007
The 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.

Imaging of aortic dissection by helical computed tomography (CT)

European Radiology, 2004
Aortic dissection is the most frequent cause of aortic emergency, and its outcome is still frequently fatal. The management of this pathology has changed with the development of endovascular means. Nowadays, imaging modalities are helpful in management decision-making by providing information such as identification of entry tears along the aorta and ...

Impact of helical computed tomography on the rate of negative appendicitis

The American Journal of Emergency Medicine, 2006
To assess the impact of helical computed tomography (HCT) on the rate of negative appendicitis (NA).A before-and-after comparison study comparing data from a prospective consecutive case series to data from a retrospective chart review. The prospective series included all patients presenting to the ED during a 19-month period, during which patients ...

Helical computed tomography in the assessment of abdominal aortic pathology

Australasian Radiology, 1997
SUMMARYA pilot study was undertaken to evaluate the role of helical computed tomography in the assessment of abdominal aortic pathology. A total of 17 patients underwent intra‐arterial digital subtraction angiography (IADSA) and helical computed tomography, with eight patients undergoing subsequent operative intervention.
