What is one advantage of ultrasound over other imaging modalities like CT or MRI for ocular evaluation?

One significant advantage of ultrasound in ocular evaluation is that it does not expose patients to ionizing radiation. Unlike imaging modalities such as computed tomography (CT) and magnetic resonance imaging (MRI), which involve radiation and may have associated risks, ultrasound uses sound waves to generate images. This safety profile is particularly important in ocular assessments, as practitioners often examine sensitive populations, including children and pregnant individuals, where minimizing radiation exposure is crucial. Additionally, the non-invasive nature of ultrasound makes it a preferred choice for follow-up evaluations and for patients requiring frequent assessments, allowing for repeated imaging without the concerns related to radiation dosage.
