CTP Imaging of Lung Cancer (CTPLC)
CTP (Computed Tomography Perfusion) Imaging of Lung Cancer
Investigators hope to learn more about how to use computed tomography (CT) scans to measure blood flow in lung tumors and how it may change in response to treatment. This measurement technique is called computed tomography perfusion (CTP). CT scanners use X-rays to produce 3-dimensional images of the body.
Currently, doctors determine the response to treatment by measuring the size of the tumor. Investigators are trying to find out if measuring the blood flow in the tumor is equal to or better than measuring the size of the tumor.

设计细节
队列和干预
团体/队列 |
---|
Variability of measurements
variability of CTP measurements will be determined by repeating the CTP examination, and comparing the resultant blood flow estimates
|
Treatment induced effects
The magnitude of treatment induced effects will be assessed by comparing tumor blood flow estimates before and after treatment
