Medical imaging plays a crucial role in cancer care, enabling radiation therapy planning, treatment delivery, and evaluation of its effectiveness. The use of advanced imaging techniques in radiation therapy has revolutionized cancer treatment and improved patient outcomes. In this context, medical imaging serves the following functions.
Assessment of localization and spread of the disease
Medical imaging can determine whether cancer is in its early stages or has spread to other parts of the body. Imaging-guided procedures, such as biopsies, are minimally invasive and essential for accurate tissue diagnosis.
Medical imaging techniques such as computed tomography (CT), ultrasound, magnetic resonance imaging (MRI), and positron emission tomography (PET) are essential for accurate diagnosis and cancer staging. These techniques help determine the location, size, and extent of tumor spread, as well as its relationship to adjacent tissues and the presence of metastases.
Creating a treatment plan
Imaging is used in treatment planning, ranging from medication and radiation therapy to surgery or, in some cases, palliative care. When planning radiation therapy, imaging creates 3D images of the tumor, allowing for more precise targeting of radiation while minimizing damage to healthy tissue.
Image-guided radiation therapy (IGRT) utilizes real-time medical imaging during radiation therapy. This method ensures precise and uniform delivery of radiation doses.
