Radiology Overview

Branches of Radiology

• Diagnostic Radiology: uses imaging technologies to diagnose and manage diseases
• Interventional Radiology: uses imaging-guided procedures to treat diseases
• Therapeutic Radiology: uses radiation to treat cancer and other diseases

Imaging Modalities

• X-ray: uses X-rays to produce images of internal structures
• Computed Tomography (CT): uses X-rays and computer algorithms to produce detailed cross-sectional images
• Magnetic Resonance Imaging (MRI): uses strong magnetic fields and radio waves to produce detailed images of internal structures
• Ultrasound: uses high-frequency sound waves to produce images of internal structures
• Positron Emission Tomography (PET): uses small amounts of radioactive materials to produce detailed images of metabolic activity
• Mammography: uses low-energy X-rays to produce detailed images of the breast tissue

Radiology Applications

• Cancer diagnosis and treatment: radiology plays a crucial role in diagnosing and treating cancer
• Trauma and emergency care: radiology helps diagnose and manage injuries and acute conditions
• Neuroimaging: radiology helps diagnose and manage neurological conditions such as stroke and brain tumors
• Cardiovascular imaging: radiology helps diagnose and manage cardiovascular conditions such as heart disease and vascular disorders

Radiology Professionals

• Radiologists: medical doctors who interpret imaging studies and perform interventional procedures
• Radiologic Technologists: healthcare professionals who operate imaging equipment and assist radiologists
• Radiation Therapists: healthcare professionals who administer radiation therapy to patients

Radiology Safety Considerations

• Radiation exposure: minimizing radiation exposure to patients and healthcare professionals
• Contrast agent safety: ensuring safe use of contrast agents used to enhance imaging studies
• Imaging equipment safety: ensuring proper maintenance and operation of imaging equipment
