Several imaging modalities are employed to monitor target lesions:
CT Scans (Computed Tomography): Often used due to their high resolution and ability to capture detailed cross-sectional images of the body. MRI (Magnetic Resonance Imaging): Provides excellent soft tissue contrast and is particularly useful for brain and spinal lesions. PET Scans (Positron Emission Tomography): Often combined with CT (PET-CT) to provide both metabolic and anatomical information. Ultrasound: Used in specific cases, particularly for superficial lesions or those in the liver.
