Imaging protocols MRI and CT
Conclusions
Imaging modalities for EBRT :
-
CT = gold standard for EBRT
Key issuses for image acquisition and patient preparation:
IV and oral contrast
Delayed acquisition for bladder
Filled bladder
Patient positioning: e.g. belly board
Dietary advices
Most authors recommend repetitive-imaging, especially for IMRT
-MRI may assist delineation for EBRT due to fusion with CT, but it is required for IGABT
specific protocol is required (see GYN GEC ESTRO recommendations)
Imaging modalities for BT:
-
MRI = gold standard for BT
Key issues for image acquisition:
see GYN GEC ESTRO recommendations
(ADVANCED MRI !!!)
-
CT = alternate option
(if MRI not available)
Key issues for image acquisition
retrograde contrast to bladder
IV contrast
multiplanar imaging
