Which imaging technique is useful for detecting calcifications in retinoblastoma?

In the context of retinoblastoma, an eye cancer primarily seen in children, calcifications are a key feature that can help in diagnosis and evaluation. Ultrasound is particularly useful in pediatric ophthalmology because it allows non-invasive assessment of the eye and surrounding structures, enabling visualization of intraocular masses, including those that may have calcifications due to tumor growth.

Ultrasound employs sound waves to create images and can effectively reveal the presence of calcifications in the tumor, which is a common characteristic of retinoblastoma. It is especially advantageous for children since it avoids the exposure to ionizing radiation associated with other imaging techniques.

While MRI and CT scans can also detect calcifications, ultrasound stands out due to its accessibility, lack of radiation, and ability to provide immediate information in a setting where young patients are involved. Therefore, in the specific context of detecting calcifications associated with retinoblastoma, ultrasound is a preferred choice.
