Can B-ultrasound examination determine liver cysts and liver tumors?
Ultrasound examination may not always reliably differentiate between hepatic cysts and liver tumors; the determination depends on the specific types of liver cysts and tumors. Details are as follows:
1. Yes
Ultrasound is a commonly used imaging technique that works by using the reflection and refraction of ultrasound waves at interfaces between different media to generate images. For typical hepatic cysts and liver tumors, ultrasound can be used for differential diagnosis. On ultrasound, hepatic cysts typically appear as round or oval lesions with low density or low echogenicity, and have well-defined, clear boundaries. Liver tumors, which may be benign or malignant, are often solid lesions and usually appear on ultrasound as high-echogenicity or mixed-echogenicity masses with poorly defined borders.
2. No
Certain cystic liver tumors, particularly cystadenomas, may not present with typical features on ultrasound. Similarly, some complicated liver cysts may also lack typical characteristics, making accurate differentiation difficult. In such cases, contrast-enhanced CT or MRI is generally required to achieve an accurate diagnosis.
Patients are advised to undergo appropriate examinations under the guidance of a physician to confirm the diagnosis, identify the underlying cause, and receive targeted treatment.
