OKZ0188008 – The Objective, Operation, and Exposure of CTs in Detecting Cancers (1 Credit)
In the past, the detection of tumors relied on the clinical presentation of the tumor, as well as some subtle radiographic findings. This, in turn, meant that tumors had to reach a size at which they caused clinical symptoms before being suspected, and radiographic detection of tumors was extremely radiographer- and radiologist-dependent. With the advent of Computed Tomography (CT), tumors were detected before they caused significant clinical symptoms, particularly during CT examinations done for other causes.
After reviewing this article, the student should be able to:
- Explain the findings determined by the modality of CT.
- Define the relationship of CTs and radiation exposure.
- Identify the different benign and malignant tumors.
