Radiology, 2000
The most commonly used imaging modality in patients with cancer is computed tomography (CT). Whether to evaluate primary tumor or metastases to the neck, chest, abdomen, or pelvis, oncologic body CT has become invaluable to medical, gynecologic, and radiation oncologists.

Hybrid SPECT/CT and PET/CT Imaging
2012Hybrid imaging is becoming popular in cardiac imaging and currently refers to combining CT imaging with nuclear imaging techniques such as positron emission tomography (PET) or single-photon emission CT (SPECT). Hybrid imaging offers the ability to assess the anatomy of the heart and coronary arteries, as well as the functional evaluation, at rest and ...

CT and MR imaging of craniopharyngioma
European Radiology, 1997We reviewed imaging findings of CT and MR imaging in 20 cases of surgically confirmed craniopharyngioma in an attempt to determine their relation to patterns of tumor extent. The relationship between these patterns and the frequency of preoperative CT diagnosis and MR imaging diagnosis according to the surgical diagnosis were determined.

CT Imaging of Coronary Arteries
2015Coronary artery disease (CAD) is one of the leading causes of mortality and morbidity in Europe and in the USA, representing high sanitary costs for insurance and national health systems. Coronary angiography is still the gold standard for the real-time visualisation and assessment of coronary circle and a fundamental interventional tool for ...

CT Imaging of the Vulnerable Plaque
Current Treatment Options in Cardiovascular Medicine, 2017Acute coronary syndromes are most often the result of vulnerable atherosclerotic plaque events. Plaques events occur when intimal fibroatheroma in the coronary artery wall becomes vulnerable to erosion or rupture. Such vulnerable plaques can be distinguished from quiescent atheroma by features that have been defined through histopathology and invasive ...

The stylohyoid chain: CT imaging
European Journal of Radiology, 2010We aimed in this report to discuss the embryology, anatomy, theories of ossification and symptoms, clinical presentation, and diagnosis of the stylohyoid chain (SHC) variations, together with the role of radiographs, computed tomography (CT) and three-dimensional (3D)-CT in showing these variations.

Investigative Radiology, 1999
To investigate image mottle in conventional CT images of the abdomen as a function of radiographic technique factors and patient size.Water-filled phantoms simulating the abdomens of adult (32 cm in diameter) and pediatric (16 cm in diameter) patients were used to investigate image mottle in CT as a function of x-ray tube potential and mAs.

Functional CT imaging in oncology
European Radiology, 2003The two-compartment pharmacokinetics exhibited by iodinated contrast media makes these agents well suited to the study of tumour angiogenesis in which new vessels are not only produced in greater number but also are abnormally permeable to circulating molecules.
