Abstract

Rhizophora spp. type of mangroves have been tested to make it as a possible human breast tissue equivalent magnetic resonance image (MRI) phantom that is realistic, inexpensive and stable over time. This study involves variations of relaxation times with water distribution inside Rhizophora spp. wood phantom. The sample was fabricated to comparable breast phantom dimension and evaluated by using breast coils at different MRI imaging sequences available for diagnosis using 1.5T clinical MRI equipment. The T1 relaxation time were measured using spin echo sequence with six repetitions and fast spin echo sequence were used to measure T2 relaxation time with six echoes. The fabricated phantom was found to have mean T1 values of ROI 1, ROI 2, ROI 3 and ROI 4, 434.78 ms ± 23.05 , 714.28ms ± 16, 666.67ms ± 19.70ms and 454.55ms ± 26.63, respectively. T2 values of 76.92 ± 20.85ms, 84.03ms ± 29.29, 89.28ms ± 29.07 and 79.36ms ±19.2, respectively. The change on the results due to water distribution and organic substances inside the sample. The relaxation times measured are similar to human breast tissue, especially fat and normal fibroglandular tissue.
