A Novel Positive Contrast Magnetic Resonance Imaging Planning Marker for High Dose Rate Image Guided Brachytherapy

Compare with Computed tomography (CT), Magnetic resonance imaging (MRI) is superior in anatomical delineation. This feature of MRI facilitates the improvement of radiation dose distribution for both tumor treatment and normal tissues protection in high-dose-rate brachytherapy (HDR-BT) by using MRI compared with CT-Ultrasound guided treatment planning and dosimetric evaluation. However, the application of MRI approach was limited due to the lack of positive contrast MRI line markers that could clearly delineate the lumen of the HDR applicator and therefore precisely show the path of the HDR source.
