CT and CT Angiography — Basics
2012The development of spiral computed tomography (CT) has seen the transformation from single slice to multislice scanners with 2, 4, 8, 16, 32, 40 and 64 detector rows with single or dual-source [1, 2, 3, 4, 5, 6, 7, 8, 9]. The most significant improvements include the increase in gantry rotation speed and consequent increase in temporal resolution, the ...

A case of clinically unsuspected pneumoparotitis diagnosed by CT is presented. The CT demonstration of air collections in the parotid gland and in the parotid ducts until their buccal orifices, as well as in the adjacent high-pressure buccal air pockets, determines the diagnosis.

Computed tomography (CT) provides important information in the evaluation of the musculoskeletal system. It represents the completion of a diagnostic path started with conventional radiography (XR). When the XR images do not allow a clear diagnosis, CT plays a fundamental role, especially with the supplement use of multi-planar and three-dimensional ...

CT Portography by Multidetector CT
2004Variceal hemorrhage is the most feared and life-threatening complication of portal hypertension. Because the portal venous system is located between the arterial and venous systems, it is difficult to image this system non-invasively. Although conventional portography has been considered as a standard for imaging of the portal venous system, arterial ...

Integrated modality imaging with PET-CT and SPECT-CT: CT issues [PDF]
European Radiology Supplements, 2005 The advantages of combining PET with CT are multiple and due to the anatomic referencing and the attenuation correction capabilities, which CT introduces, as well as a resulting increase in imaging speed and more efficient use of radiopharmaceuticals. These synergistic advantages are gained with combining PET-CT, but less so when combining SPECT-CT and

Neurosurgical Review, 1989
There were 276 patients with severe head injuries admitted to the Neurosurgical Clinic of the A.H.E.P.A University Hospital during the last two years. Comatose state, dilated pupils without reaction to light and respiration disturbances (Glasgow Score 7) were the main characteristic state in 60% of the patients. Computed Tomography (CT) cases.

Radiation dose management in CT, SPECT/CT and PET/CT techniques
Radiation Protection Dosimetry, 2011New imaging technologies utilising X rays and radiopharmaceuticals are continuously under development. The benefit of computed tomography (CT) has been so dramatic that there is a tendency to overuse it and not to place enough efforts into optimisation of the technique. It is also now more and more common to combine two imaging techniques into a single

Ugeskrift for laeger, 2020
Cardiac CT has become a frequently used diagnostic modality in Denmark, especially for the evaluation of coronary artery disease indicated by angina pectoris/dyspnoea. Indications have recently expanded to include evaluation of valvular heart disease, pre- and post-procedural evaluation related to several invasive procedures as well as some congenital ...

ADVANCED CT IMAGING (FUNCTIONAL CT)
Neuroimaging Clinics of North America, 1999Computed tomography can provide anatomic and functional information about the brain. The conventional CT of the brain can be coupled with a cerebral blood flow examination using the stable xenon CT technique and with a CT angiography. Distinct subgroups of patients based on variations in cerebral blood flow and vascular pathology have been demonstrated.
