X-ray computed tomography (CT) has replaced X-ray projection techniques. CT provides images of brain cross sections in “digital” quality. In CT, an X-ray tube and detectors mounted on the opposite side in relation to the object move in a circle, with the object under study being in the center.

Computed Tomography (CT) Analysis of the Effects of Chemonucleolysis
Clinical Orthopaedics and Related Research, 1986Computed tomography (CT) was performed on 30 patients with herniated lumbar discs before chemonucleolysis and at three and 12 months postinjection. At three months the compression produced by the herniated disc was reduced in 20 of the 30 patients; at 12 months there was complete relief of compression in all but four patients.

Computed tomography (CT) is based on attenuation of X-ray beam passing through an examined object. Linear X-ray attenuation coefficient is calculated separately for each voxel, i.e. cuboid volumetric element which constitutes each scanned layer, and the coefficients are transformed into the Hounsfield units (HU), which make it possible to estimate ...

Computed Tomography (CT) and CT Arthrography
2003Over the last two decades, sectional imaging has developed rapidly. Computed tomography (CT) and magnetic resonance (MR) imaging are now established methods of investigation of the knee and both methods continue to develop such that descriptions of the current state of the art remain valid for only months.

Journal of Surgical Oncology, 2011
AbstractHybrid systems associating the sharpness of anatomic images coming from computed tomography (CT) and radionuclide functional imaging (SPET or PET) are opening a new era in oncology. This multimodal imaging method is now routinely used for the diagnosis, extent, follow up, treatment response and detection of occult disease in different types of ...

An investigation of Etruscan cremations by Computed Tomography (CT)
Antiquity, 2010The cremation urn is a tiny archaeological site of its own, with finds, features, stratification and structure. The old prescription was to take the pot apart, or slice it, and micro-excavate with inevitable damage and loss. Here is a new methodology – the application of a CT scan as used in medicine.

Computed tomography (CT) in the diagnosis of sinus aspergillosis
Journal of Cranio-Maxillofacial Surgery, 199419 patients with radiodense sinus concretions found on standard radiography underwent a preoperative computed tomographic examination of the sinus maxillaris and the sinus concretions. 13 patients (68.4%) with the occurrence of radiodense concretions presented postoperative histologically and microbiologically diagnosed sinus aspergillosis infection ...

Principles of Computed Tomography (CT)
2012The increasing availability, speed, and reliability of computed tomography has resulted in its widespread use in urological imaging. Understanding the basic physics and technology behind this imaging modality, along with familiarity of scan techniques and use of contrast, allows performance of the optimal scan for diagnostic purposes.

Porencephaly: Computed tomography (CT) scan findings
Computerized Radiology, 1987Twenty-six cases of porencephalic cysts were analyzed. The cysts were multiple in 26.9% and were associated with subarachnoid cysts in 11.5%. The main presentations were seizures, cerebral palsy and mental retardation. The unifocal cysts were mainly in the frontoparietal region, suggesting a congenital aetiology.
