Diagnostic Imaging of the Lower Extremity - Key Terms

Vocabulary flashcards covering imaging modalities, radiographic views, pelvic/hip anatomy, radiographic lines, and common imaging findings from the lecture notes.

What is the appearance and usefulness of an X-ray (Radiograph)?

Appearance: Provides 2D planar projections from multiple views. Usefulness: First-line imaging modality for many acute musculoskeletal injuries.

What is the appearance and usefulness of Computed Tomography (CT)?

Appearance: Offers cross-sectional imaging with high bone detail. Usefulness: Good for fractures, vascular injury, and soft-tissue pathology, with rapid acquisition.

What is the appearance and usefulness of Magnetic Resonance Imaging (MRI)?

Appearance: Provides cross-sectional imaging with superior soft-tissue contrast. Usefulness: Best for joint and soft-tissue pathology, though timing/tolerance can limit immediate use.

What is the appearance and usefulness of Nuclear Medicine (Radionucleotide Imaging)?

Appearance: Conducts functional imaging using radiotracers, providing limited anatomical detail. Usefulness: Useful for malignancy, infection, and metabolic activity.
