Computed Tomography, Computed Tomography Angiography, and Perfusion Computed Tomography Evaluation of Acute Ischemic Stroke

Neuroimaging Clinics of North America, 2018
This review outlines the current role of the individual components of multimodal computed tomography (computed tomography, computed tomography angiography, and perfusion computed tomography) in the evaluation of patients with acute ischemic stroke.

Quantitative Computed Tomography and Computed Tomography in Children

Current Osteoporosis Reports, 2011
Quantitative computed tomography (QCT) methodologies have been instrumental in deepening our understanding of bone acquisition and strength during childhood. Important publications in the last year have drawn attention to the functional muscle-bone unit, showing that factors such as population ancestry, bone size, and muscle composition are additional ...

Interventional computed tomography

Current Problems in Diagnostic Radiology, 1988
Due to the development and refinement of computed tomography (CT), sonography, and interventional techniques, the field of interventional radiology has seen tremendous growth in recent years. In particular, the precise anatomic detail provided by CT and sonography has allowed percutaneous biopsies and abscess drainages to be performed safely and ...

Computed tomography of thorotrastosis

Journal of Computed Tomography, 1987
Two cases of thorotrastosis examined by computed tomography are reported. The appearance of the liver, spleen, and lymph nodes is diagnostic. This technique is probably the procedure of choice for detection of Thorotrast-induced liver neoplasm.

Computed Tomography of Choledochocele

Journal of Computer Assisted Tomography, 1985
One case of choledochocele is reported, and the findings on CT, endoscopic retrograde cholangiopancreatography, and surgery are described. At surgery, in addition to choledochocele, a large choledochal cyst in the proximal common bile duct was discovered.

Quantitative computed tomography

Radiologic Clinics of North America, 2003
Unlike dual x-ray absorptiometry and high-resolution CT scan and MR imaging techniques, which are largely restricted to the peripheral skeleton owing to radiation dose and signal-to-noise considerations, volumetric quantitative measures provide measures of cortical and trabecular volumetric bone mineral density, cross-sectional geometry, and estimates ...

Emission Computed Tomography

Neurosurgery, 1978
Emission computed tomography (CT) is a nuclear medicine visualization technique that yields an image of the distribution of a previously administered radionuclide in any desired transverse section of the body. Emission CT allows the safe, quantitative, three-dimensional measurement of regional radionuclide distribution in tissue.

Computed tomography dacryocystography

European Journal of Radiology, 1995
Twenty-one patients with epiphora were examined by conventional dacryocystography, using Lipiodol as a contrast medium, and CT dacryocystography, using a water soluble contrast medium. In the latter, the material was not introduced under pressure but three or four drops were administered, providing a physiological method of investigation. Subsequently,

Computed Tomography and High-Resolution Computed Tomography of Pneumoconioses

Journal of Occupational and Environmental Medicine, 1991
The traditional imaging technique used in the assessment of patients suspected of having silicosis or asbestos-related disease has been the chest radiograph. However, computed tomography and high-resolution computed tomography have become widely available for these assessments.

Computed tomography of oleothorax

Journal of Computed Tomography, 1986
Oleothorax as therapy for pulmonary tuberculosis was discontinued some 35 years ago. An oleothorax may expand and cause respiratory distress. Additional complications include bronchopleural fistula and cutaneous fistula. Computed tomography has not previously been used to evaluate oleothorax. This case report describes the use of computed tomography in
