From: Post-treatment MRI aspects of photodynamic therapy for prostate cancer
Haemorrhage within treated lobes is variable. a Day-7 post-treatment axial T1 MR image in a 64-year-old patient with right lobe photodynamic therapy shows an asymmetric prostate (star) with increased volume of the treated lobe but without any spontaneous high signal intensity evoking haemorrhage in the treated area. b A 72-year-old patient with left lobe treatment. Day-7 post-treatment axial T1 shows a hyperintense area (arrowhead) corresponding to post-treatment haemorrhagic suffusions. c Right lobe phototherapy in a 59-year-old patient. Day-7 post-treatment axial T1-weighted MR image shows a spontaneous high-signal-intensity area in the right lobe (arrowhead), but also an extended spontaneous high signal intensity in the left (untreated) lobe (star)
