The primary imaging modalities in radiology include X-ray, ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), nuclear medicine (including PET scans), and fluoroscopy. Each modality has specific uses depending on the clinical scenario. For example, X-rays are commonly used for bone fractures, chest imaging, and dental assessments; ultrasound is preferred for soft tissues and obstetric evaluations; CT and MRI provide detailed cross-sectional images useful for detecting tumors, vascular diseases, and neurological conditions. Interventional radiology, a subspecialty, uses imaging guidance to perform minimally invasive procedures like biopsies, angioplasty, and drain insertions.
