Figure 3From: Improve definition of titanium tandems in MR-guided high dose rate brachytherapy for cervical cancer using proton density weighted MRIComparison of histograms of signal intensity between (a) T2W and (b) PDW MRI. Histograms were obtained based on a small ROI placed around the tip of the tandem. Two peaks corresponding to the uterus and the tandem were overlapped in the T2W image but separable in the PDW image.Back to article page
