Abstract:
This article provides an overview of the primary considerations of positron emission tomography-computed tomographic (PET-CT) workflows specifically related to patient and image data management in radiation therapy (RT) planning and therapy response assessment. PET-CT has become increasingly integral to the RT planning and therapy response assessment. There are numerous workflow challenges related to integrating PET-CT in the framework of RT planning and therapy assessment. For PET-CT scan used for RT planning, accurate patient positioning and scan registration with the simulation is critical. For therapy assessment PET-CT scans, consistency in patient preparation, scanning and image reconstruction parameters, and image analysis are critical.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
