Complete abdominal ultrasound is a dynamic, operator-dependent examination influenced by patient preparation, body habitus, and the clinical question. A “normal abdominal ultrasound” template should therefore never assume that every organ was adequately visualized.
A reliable report requires systematic assessment of the liver, gallbladder and bile ducts, pancreas, spleen, kidneys, urinary bladder, and—depending on local scope—the pelvis and retroperitoneal structures. When bowel gas, obesity, inadequate fasting, or poor bladder filling limits the study, the limitation should be stated explicitly.
Clinical safety note: An organ that was not visualized or was only partly visualized should not be reported as normal. Template text does not replace real-time scanning or measurements.
Assess size, contour, echogenicity, homogeneity, and focal lesions. Review the portal vein, hepatic veins, and intrahepatic bile ducts according to the examination scope. Echogenicity is influenced by machine settings and comparison with the renal cortex.
Evaluate gallbladder distention, wall thickness, lumen, stones, sludge, and the pericholecystic region. A nonfasting patient may have a contracted gallbladder. Common bile duct size should be interpreted in the context of age, cholecystectomy history, and clinical findings.
Assess the head, body, and tail whenever possible. If bowel gas obscures part of the gland, use wording such as “the visualized portions are unremarkable” rather than “the pancreas is normal.”
Assess size, contour, and parenchymal homogeneity. Measurement technique should be standardized locally.
Evaluate size, contour, cortical thickness and echogenicity, collecting systems, stones, and focal lesions. The statement “no stone” should be used with awareness that ultrasound is limited for very small or ureteral calculi.
Assess distention, wall thickness, and the lumen. Inadequate distention can make the wall appear falsely thickened. Postvoid residual measurement requires a dedicated protocol when clinically requested.
In women, the uterus and ovaries may be assessed when included in the examination and adequately visualized. In men, the prostate may be assessed according to local practice. Transabdominal ultrasound does not replace a dedicated pelvic or transvaginal examination when one is needed.
The visible abdominal aorta and the peritoneal spaces may be reviewed for aneurysmal dilatation and free fluid. Dedicated aortic screening follows its own standards.
The liver is normal in size and contour with homogeneous echogenicity. No focal solid or cystic lesion is identified. The intrahepatic bile ducts and common bile duct are not dilated. The gallbladder is adequately distended with normal wall thickness. No stone or sludge is identified. The visualized portions of the pancreas are unremarkable. The spleen is normal in size and echotexture. Both kidneys are normal in size and contour with preserved cortical thickness and echogenicity. No hydronephrosis or definite calculus is identified. The urinary bladder is adequately distended and shows no focal wall or intraluminal abnormality. No free fluid is identified in the abdomen.
Impression: No significant sonographic abnormality in the abdomen.“The visualized portions of the pancreas” is safer when the entire gland was not confidently seen.
Use only when adequately assessed transabdominally:
The uterus is normal in size and contour with homogeneous myometrium. Endometrial thickness is interpreted in relation to the patient’s age and menstrual status. Both ovaries are normal in size and appearance. No adnexal mass is identified. No free fluid is present in the cul-de-sac.A single fixed statement about normal endometrial thickness should not be applied to all patients.
The prostate is within expected limits in size and sonographic appearance for age. No focal abnormality is identified in the urinary bladder. No free pelvic fluid is present.When prostate volume is measured, reporting the numeric value is more transparent than relying only on “age appropriate.”
The examination is limited by bowel gas and reduced patient cooperation. The pancreatic tail and portions of the retroperitoneum are not adequately visualized. No significant abnormality is identified in the visualized abdominal organs.A limited examination should not be concluded as completely normal.
The liver, gallbladder, bile ducts, spleen, visualized pancreas, and both kidneys are unremarkable. No hydronephrosis or definite calculus is identified. The urinary bladder is unremarkable. No free fluid is present.
Impression: No significant sonographic abnormality.Even with a short report, the organs should have been systematically reviewed and measurements recorded when required.
Bowel gas is a common limitation. “Visualized portions” accurately defines the scope of assessment.
Inadequate fasting may explain contraction. Preparation and clinical context should be reflected in the report.
Expected diameter varies with age, surgical history, and measurement site. Provide measurements and interpret them in context.
Ultrasound may miss small or ureteral calculi. A negative ultrasound does not always resolve persistent clinical suspicion.
Endometrial and ovarian appearance varies with age and hormonal state.
It depends on the clinical question and local protocol. Numeric measurements improve reproducibility when a structure is borderline, abnormal, or being followed.
The entire study should not be labeled normal without qualification. State which portion was not visualized and why.
No. Ultrasound sensitivity varies with stone size and location.
