Introduction
What can B-mode ultrasound detect?
Abdominal B-mode ultrasound can be used to examine the liver, gallbladder, spleen, and kidneys. It enables assessment of the structural integrity of these organs and detection of abnormalities such as masses or tumors. For patients with liver or gallbladder disease, B-mode ultrasound aids in confirming the diagnosis and monitoring disease progression or resolution. Cranial B-mode ultrasound can evaluate the normal anatomy of various brain tissues and detect the presence of intracranial tumors.
B-mode ultrasound (B-ultrasound) is a commonly used diagnostic imaging modality. Whether for routine health check-ups or evaluation of specific diseases, patients frequently undergo B-ultrasound examinations at hospitals. As a type of ultrasound imaging, B-ultrasound can detect a wide range of conditions. By analyzing the echo patterns generated by sound waves reflecting off internal tissues, clinicians can identify pathological lesions, assess disease severity, and evaluate overall health status. Common applications include abdominal, cranial, and hepatic examinations, among others. Below is a brief overview of the conditions B-ultrasound can detect.
What Can B-Ultrasound Detect?
In routine health examinations, B-ultrasound is frequently employed to evaluate the abdomen, brain, and heart.
Abdominal B-ultrasound is used to examine the liver, gallbladder, spleen, and kidneys. It enables assessment of organ structure, detection of abnormalities such as masses or structural anomalies, and monitoring of disease progression or treatment response—particularly in patients with hepatobiliary disorders.
Cranial B-ultrasound helps evaluate the integrity and morphology of various brain structures and can detect intracranial tumors or other abnormalities.
Cardiac B-ultrasound (echocardiography) provides detailed visualization of cardiac valve morphology and mobility, dimensions and geometry of the atria and ventricles, and anatomy of major vessels entering and exiting the heart.
However, B-ultrasound is most frequently utilized in routine gynecological examinations, enabling detection of abnormalities in the uterus, fallopian tubes, ovaries, and pelvic cavity—including congenital uterine malformations, uterine fibroids, ovarian cysts, and pelvic inflammatory disease.
Preparation Guidelines for B-Ultrasound Examinations
B-mode ultrasound has broad clinical applications, and preparation requirements vary depending on the anatomical region being examined: ① Abdominal examination (e.g., liver, gallbladder, pancreas, spleen, and peritoneal cavity): Fasting is generally required. Food intake induces gas accumulation in the stomach and intestines, which impedes ultrasound wave transmission; therefore, fasting yields optimal image quality. ② Gynecological examination: Patients should drink water and retain urine to achieve bladder distension. A full bladder displaces overlying bowel loops, facilitating clearer ultrasound penetration into the pelvis and improved visualization of the uterus and ovaries—both normal anatomy and pathology. ③ Urinary tract examination: Adequate hydration is recommended to ensure bladder filling, thereby enhancing detection of urinary tract calculi, tumors, polyps, and other abnormalities. ④ Superficial mass or lesion examination: Typically requires no special preparation and can be performed immediately. ⑤ Cardiac and peripheral vascular examinations: Usually require no specific preparation.
The above outlines key applications of B-ultrasound. We hope this information is helpful to you.
