Study Notes
Radiography is a medical imaging technique used to visualize internal structures of the body. Interpreting radiographs requires knowledge of various pathological conditions, common findings, and the anatomy they depict.
Pathological Conditions
Pathological conditions refer to any deviation from normal health. In radiography interpretation, identifying these conditions is crucial. Some examples of pathological conditions include:
- Pneumonia: This condition results from infection by bacteria, fungi, or viruses within the lung tissue and air spaces. A typical radiographic finding for pneumonia is focal opacities with or without air bronchograms.
- Tuberculosis: Tuberculosis is a mycobacterial disease often affecting the lungs, leading to parenchymal consolidation, cavitary lesions containing caseous necrosis, and pleural thickening. These features can manifest on chest X-ray images.
- Lung Cancer: Lung cancer appears as irregularly shaped nodules and masses.
- Fractures: Fractures appear as discontinuities along bone structures, commonly seen in the spine, ribcage, upper extremity bones, pelvis, and lower extremity bones.
- Osteoporosis: Osteoporosis manifests as decreased bone mineral density resulting in reduced bone mass and increased risk of fracture. On radiographs, this might present as vertebral compression fractures.
Common Findings
Common findings on radiography examinations include:
- Air Bronchograms: Air bronchograms occur when air fills the lumen of bronchioles which normally contain mucus due to altered pulmonary blood flow, such as in atelectasis or acute respiratory distress syndrome (ARDS).
- Calcification: Calcifications can be found in the liver, pancreas, kidneys, and third portion of the duodenum. They may indicate inflammation, cancer, or chronic reflux.
- Osteosclerosis: Osteosclerosis refers to abnormal increase in bone density, which could indicate osteomalacia or Paget's disease of the bone.
- Gas Bubbles: Gas bubbles in the interstitium of the lung or other organs, called pneumatocele, are visible as rounded lucencies surrounded by hyperdense rim.
Anatomical Structures
Understanding the anatomy of the areas being examined is essential for accurate interpretation of radiographs. Some key anatomical structures include:
- Spine: The spine consists of 7 cervical, 12 thoracic, 5 lumber, 5 sacral, and 4 coccygeal vertebrae.
- Ribcage: The rib cage includes the sternum, cartilages, and 12 pairs of ribs.
- Heart: The heart is located between the lungs and slightly left of midline. Its size on supine AP view is estimated based on the distance between the nipple line and the rightward margin of the cardiac silhouette.
- Lower Extremities: The femur, tibia, fibula, and foot bones are important structures in orthopedic radiology.
