In-room imaging and MR planning

MRI-guided adaptive brachytherapy

Left panel shows transverse MRI at time of diagnosis with PMI (left and right). At the time of BT, there was still residual PMI. A combined intracavitary- interstitial applicator (5 needles) was used. Middle and right panel show paratransverse and coronal MRI at the time of BT. The volumes are as follows: residual GTV magenta), CTV HR (red), CTV IR (pink), bladder (yellow), and sigmoid (orange). Isodoses 15 Gy (cyan) and 7.5 Gy (green) correspond to 84 Gy and 60 Gy in terms of total EQD2.
