Image Based Brachytherapy in cervical Cancer CT and MRI correlation: Ongoing Research

TMH Study

Image Based Brachytherapy in cervical Cancer TAUS and MRI correlation (TMH data)

In collaboration with Peter Mac Melbourne

• Trans –abdominal Ultrasonography : Cost effective imaging modality • 32 Applications with MRI Compatible Applicator • Anterior Reference Points : 96 % • Posterior Reference Points : 72 % • Magnitude of Variation (>15%) : < 8%

Significant Correlation between the USG and MRI

Reference Points

Suggest : Use of USG for ICA Planning (21/2 D Planning)
