CT Portography by Multidetector CT

2004
Variceal 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]

open access: possibleEuropean 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

The timing of CT

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, 2011
New 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

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, 1999
Computed 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.

An 'illuminating' CT

Gut, 2011
A 56-year-old man with moderate fibrosis (F4, Ishak Fibrosis Score) secondary to non-alcohol-related fatty liver disease was transferred to our centre for the management of bleeding gastric varices. At the time of his index variceal bleed in June 2008, oesophago-gastro-duodenoscopy (OGD) demonstrated a large bleeding type 2 gastro-oesophageal fundal ...

The Appendix on CT

Clinical Radiology, 2009
Appendicitis can be a difficult clinical diagnosis to make. A negative appendicectomy rate of 20% has traditionally been accepted as the consequences of appendiceal perforation can be grave. Cross-sectional imaging is increasingly being employed in the investigation of adults with suspected appendicitis.

CT of emphysema

Radiologic Clinics of North America, 2002
This article focuses on three main topics: (1) the importance of emphysema as a serious respiratory disease, (2) qualitative assessment of emphysema using CT, and (3) the emerging importance of quantitative CT in the evaluation of patients with emphysema for surgery and drug therapy. CT also can identify the major anatomic subtypes of emphysema.
