Radiology, 2007
Computed tomographic (CT) enteroclysis is a hybrid technique that combines the methods of fluoroscopic intubation-infusion small-bowel examinations with that of abdominal CT. The use of multidetector CT technology has made this a versatile examination that has evolved into two distinct technical modifications.

Real-time CT and CT fluoroscopy
The British Journal of Radiology, 2001The development of CT scanner technology in the past 10 years has brought a range of advances, including slip ring scanning, fast (sub-second) rotation times and greater computing power. These advances have been combined to allow rapid reconstruction of CT scanner data that can be updated continuously to provide crosssectional images in near real-time.

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

Computed tomography (CT) can identify with accuracy locally advanced colon cancer and liver metastases but it cannot diagnose peritoneal carcinomatosis. CT can identify T3/T4 tumors with more than 5 mm extramural depth which are candidates for neoadjuvant therapy.

CT, CT-Angiography, and Perfusion-CT Evaluation of Stroke
2017A stroke is a sudden loss of neurological function due to brain parenchyma damage, caused either by the sudden loss of blood flow to a specific brain region (ischemic stroke) or by the rupture of blood vessels in the brain (hemorrhagic stroke). Patients with acute stroke usually present with a focal neurological deficit, but the clinical symptoms are ...

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.

Child's Nervous System, 2003
Fetal CT is helpful in the diagnosis of bony anomalies, particularly with 3D reconstructions.Because of the potential risks of irradiation, CT should not be performed before 32 weeks' gestation and should be restricted to a carefully selected group of patients.

Integrated modality imaging with PET-CT and SPECT-CT: CT issues
European Radiology Supplements, 2005The 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

[Combining CT and scintigraphy: SPECT-CT and PET-CT].
Nederlands tijdschrift voor geneeskunde, 2011In recent years tomographic hybrid scanners have been quickly introduced in nuclear medicine: single-photon emission computed tomography (SPECT)-CT and positron emission tomography (PET)-CT.- Both SPECT-CT and PET-CT techniques provide a higher diagnostic accuracy than conventional (non-tomographic, non-hybrid) bone scintigraphy (bone scan ...
