PET/CT in Abdominal and Pelvic Malignancies: Principles and Practices

摘要: Current multi-detector computed tomography (MDCT) allows for rapid acquisition of data sets with accurate anatomic detail and high spatial resolution. This provides valuable multi-planar information regarding the morphologic features attenuation values both normal structures pathologic lesions. Since its introduction more than 25 years ago, CT has become widely used can be considered modality choice much cross-sectional imaging, particularly oncologic entities. A limitation CT, however, is reliance on changes in size, shape, or a structure to detect processes. Therefore, less sensitive imaging early disease processes detection recurrence tissues that are already morphologically abnormal as result treatment.
