Study Notes
Radiographic Anatomy
Radiographic anatomy is the study of the internal structure of the body using medical imaging techniques, such as X-rays, CT scans, and MRI scans.
Importance of Radiographic Anatomy
- Essential for accurate diagnosis and treatment of diseases
- Helps in identifying normal and abnormal anatomical structures
- Guides interventional procedures and surgeries
Radiographic Views
- Anteroposterior (AP) view: X-ray beam passes from front to back
- Posteroanterior (PA) view: X-ray beam passes from back to front
- Lateral view: X-ray beam passes from side to side
- Oblique view: X-ray beam passes at an angle
Body Regions
- Cranium: skull and brain
- Thorax: chest and lungs
- Abdomen: stomach and intestines
- Pelvis: hips and reproductive organs
- Upper limb: shoulder, arm, and hand
- Lower limb: hip, leg, and foot
Radiographic Appearance of Bones
- Cortical bone: dense, compact bone appears white on radiographs
- Cancellous bone: spongy, porous bone appears grey on radiographs
- Joint spaces: appear as dark areas between bones
Radiographic Appearance of Soft Tissues
- Lungs: appear dark due to air content
- Heart: appears as a dense, white structure
- Liver: appears as a dense, right-sided structure
- Spleen: appears as a dense, left-sided structure
Radiographic Pathologies
- Fractures: appear as breaks or abnormalities in bone structure
- Tumors: appear as abnormal masses or densities
- Infections: appear as abnormal opacities or densities
Contrast Media
- Iodine-based contrast: used for CT scans to enhance visibility of soft tissues
- Barium-based contrast: used for fluoroscopy and CT scans to visualize gastrointestinal tract
- Gadolinium-based contrast: used for MRI scans to enhance visibility of soft tissues
