Normal Organ Sizes in Abdominal Ultrasound: A Summary Table for Physicians
Important Methodological Note
The provided source fragments do not contain specific numerical norms for the sizes of abdominal organs (liver, gallbladder, pancreas, spleen, kidneys). Due to the requirements for the reliability of medical information, a summary numerical table based on fragments cannot be constructed without introducing unverified data. The values below are marked as requiring clarification. [clarify]
What is Available in the Source Fragments
The fragments only provide fundamental provisions of relevant guidelines, without specific threshold values:
| Organ | Data from Fragments | Source |
|---|---|---|
| Liver | Assessed for hepatomegaly, steatosis, cysts; in 2D-SWE ROI ≥10 mm, measurement 15–20 mm below the liver capsule, optimal ARFI push-pulse distance 4–4.5 cm from the probe | WFUMB 2024; EFSUMB Core Curriculum |
| Gallbladder | Assessed for stones, cholecystitis, stagnant gallbladder, wall polyp, intrahepatic duct dilation | EFSUMB Core Curriculum (Andersen et al.) |
| Pancreas | Listed as an optional organ for description during liver ultrasound surveillance | LI-RADS US Surveillance v2024; ACR-AIUM-SPR-SRU 2023 |
| Spleen | Size significantly depends on height and gender; normal values established in a cohort of healthy individuals; assessed for splenomegaly | ACR-AIUM-SPR-SRU 2023 (Chow et al., Radiology 2016) |
| Kidneys | Described normal anatomy, variants, and congenital anomalies, Doppler ultrasound | EFSUMB Course Book 2024 (Ultrasound of the renal vessels) |
Factors Affecting Sizes (from Fragments)
According to data provided in ACR-AIUM-SPR-SRU (2023), spleen size significantly depends on body height and gender, which must be considered during interpretation; normal values were established in a cohort of 1200 healthy individuals (Chow et al., Radiology 2016). For pediatric practice, spleen length is noted to depend on age, gender, and somatometric parameters (Megremis et al., Radiology 2004). [clarify specific values]
Recommendation for Physicians
To form a correct summary table of norms, it is necessary to refer to the primary normative tables of the relevant guidelines (ACR/AIUM/SPR/SRU for abdominal ultrasound, WFUMB for the liver, EFSUMB for renal vessels) with specific threshold values, which are not presented in the provided fragments.
Frequently asked questions
Are there specific liver size norms in the sources?
No. The fragments only contain methodology (ROI ≥10 mm in 2D-SWE, measurement 15–20 mm below the capsule) without numerical liver size norms. [clarify]
What does the normal spleen size depend on according to the sources?
According to ACR-AIUM-SPR-SRU (2023, Chow et al.), spleen size significantly depends on body height and gender; norms were established in a cohort of 1200 healthy individuals. Specific values are not provided in the fragments.
What gallbladder parameters are assessed according to EFSUMB?
According to the EFSUMB Core Curriculum, stones, cholecystitis, stagnant gallbladder, wall polyp, and intrahepatic duct dilation are assessed. Numerical norms for wall thickness or sizes are not specified. [clarify]
Are kidney size norms provided?
No. The EFSUMB source (Ultrasound of the renal vessels, 2024) describes normal anatomy, variants, congenital anomalies, and Doppler ultrasound, but without numerical size norms. [clarify]
