Final answer:
The surgical specimen is radiographed to confirm that the entire lesion was removed. Radiographic imaging like X-rays or CT scans ensure the success of surgical interventions. Distinct medical imaging techniques like X-rays, CT scans, MRI, PET scans, and Ultrasound serve various functions in medicine.
Step-by-step explanation:
The surgical specimen is radiographed to confirm that the entire lesion was removed. This is a critical step post-operatively, especially in procedures involving the removal of cancerous tissues or in biopsies. Radiographic imaging, such as X-rays or CT scans, are utilized to ensure complete excision of the target lesion. Accurate imaging is essential in medicine, not only for diagnosis but also for confirming the success of surgical interventions.
Several medical imaging techniques are used for different purposes in healthcare:
- X-rays are typically used for imaging bones and certain body structures.
- CT scans involve computer processing of X-ray measurements from different angles to create cross-sectional images of organs.
- With MRI, magnetic fields generate images of soft tissues like organs.
- PET scans detect the metabolic activity of organs using radiopharmaceuticals.
- Ultrasound, which uses sound waves, is preferred in situations like pregnancy due to its non-invasive nature and absence of ionizing radiation.
