In 2005, the CT Colonography Reporting and Data System (C-RADS) was established to provide a means of classifying findings of CT colonography (CTC) and of applying the advantages of structured reporting to the setting of colorectal cancer screening.

Positron emission tomography (PET) and computed tomography (CT) complement each other’s strengths in integrated PET/CT. Most PET/CT studies in oncology are performed with 18F-fluorodeoxyglucose (FDG). FDG is a glucose analogue that is taken up and trapped within viable cells. An increased glycolytic activity is a characteristic in many types of cancers resulting in avid accumulation of FDG. These tumours excel as “hot spots” in FDG-PET/CT imaging. FDG-PET/CT proved to be of high diagnostic value in staging and restaging of different malignant diseases, such as colorectal cancer, lung cancer, breast cancer, head and neck cancer, malignant lymphomas, and many more.

Computed tomography (CT) is widely used for early evaluation of acute strokes. Most importantly, CT excludes acute hemorrhage or other diseases mimicking ischemia. Continue reading “Diagnostic Criteria of Infarction in CT Imaging of the Brain in Acute Stroke”
