Key Imaging Modalities in Radiation Therapy CT (Computed Tomography): Primary tool for treatment planning. Provides high-resolution anatomical details. MRI (Magnetic Resonance Imaging): Superior soft tissue contrast for tumors near critical structures. Functional MRI (fMRI) for assessing tumor activity. PET (Positron Emission Tomography): Detects metabolic activity and tumor aggressiveness. PET-CT combines functional and anatomical imaging. Ultrasound: Used in real-time imaging during brachytherapy. Speaker Notes: Explain how each imaging modality contributes to different aspects of radiation therapy planning and delivery. Reference: McGarry, C. K., et al. (2017).

Image-Guided Radiation Therapy (IGRT) Combines real-time imaging with radiation delivery. Corrects for patient movement and tumor shifts during treatment. Examples of IGRT technologies: Cone-beam CT (CBCT) 4D imaging for respiratory motion management Surface-guided radiation therapy (SGRT). Speaker Notes: Highlight the importance of IGRT in minimizing errors caused by patient motion or tumor changes during therapy. Reference: Jaffray, D. A. (2012).

Functional Imaging in Radiation Therapy PET-CT: Identifies tumor metabolism and aggressiveness. Diffusion-Weighted MRI: Measures cellular density for early tumor response. Dynamic Contrast-Enhanced Imaging: Assesses tumor blood flow and oxygenation. Speaker Notes: Explain how functional imaging is transforming treatment personalization by providing biological insights into tumors. Reference: Wong, K. H., et al. (2014).
