Table 1 Target volumes definition.

From: MRS-guided HDR brachytherapy boost to the dominant intraprostatic lesion in high risk localised prostate cancer

CTVCT = prostate gland + base of seminal vesicles, delineated on CT

CTVMR = prostate gland only, delineated on MRI

CTVDIL = dominant intraprostatic nodule, delineated on MRI/MRSI

PTVEBRT = CTVCT + 10 mm margin in all directions but posteriorly where 5 mm where used

PTVHDR = CTVMR

PTVDIL = CTVDIL

  1. "CTV" is the clinical target volume, "PTV" - the planning target volume, subscript "EBRT" refers to the external beam radiotherapy, "HDR" - to the high dose rate brachytherapy, "DIL" - the dominant intraprostatic lesion.
