Computed Tomography (CT)

• Multidetector Computed Tomography (MDCT): Rapidly acquires high-resolution images, enhancing tumor detection and localization.
• Helical CT: Provides spiral scan images, allowing for more accurate tumor visualization.

Positron Emission Tomography (PET)

• PET-CT: Combines PET and CT images, providing both metabolic and anatomical information.
• 18F-FDG PET: Detects glucose uptake, which is elevated in many cancer cells, enabling tumor identification and monitoring response to therapy.

Ultrasound

• Ultrasound Contrast Imaging: Enhances vessel visualization, improving tumor detection and assessment of blood flow.
• Elastography: Measures tissue stiffness, which can be an indicator of tumor presence and aggressiveness.

Mammography

• Digital Mammography: Produces high-resolution images, improving breast cancer detection and reducing false positives.
• Contrast-Enhanced Mammography: Injects contrast dye to highlight tumor tissue, enhancing tumor detection and evaluation of treatment response.

Novel Imaging Modalities
