Hepatomegaly is most commonly identified through which tool?

Hepatomegaly, which is the enlargement of the liver, is most commonly identified using ultrasound. This imaging technique is non-invasive, widely accessible, and particularly effective in evaluating soft tissues, making it ideal for assessing organs such as the liver. Ultrasound can provide real-time images and is particularly useful for determining the liver's size and structure, allowing clinicians to visualize any abnormalities that may contribute to hepatomegaly.

While other imaging modalities, such as MRI and CT scans, can also be used to evaluate the liver, they are generally more costly and may not be the first choice in initial assessments for liver enlargement, especially in routine clinical settings. X-rays are less effective in assessing soft tissue details compared to ultrasound and are not typically used to diagnose conditions like hepatomegaly. Therefore, the use of ultrasound stands out as the preferred method for identifying hepatomegaly.
