Cancer Imaging
Cancer imaging radiology, also known as oncologic imaging, is a subspecialty of radiology focused on the detection, diagnosis, staging, monitoring, and follow-up of cancer using various imaging techniques. Radiologists specializing in cancer imaging use advanced technologies to visualize tumors, assess the extent of cancer spread (metastasis), and guide treatment plans such as surgery, radiation, or chemotherapy.
Modalities Used in Cancer Imaging
- X-rays are often the first imaging tool used to detect lung or bone metasteses
- CT scans help to locate tumors, assess their size, and check for metastasis
- MRI can help assess tumor size, location, and involvement with nearby structures
- PET detects metabolic activity in tissues, which is often higher in cancer cells
- Ultrasound can guide biopsies, check for fluid buildup, and monitor tumor progression
