Hello, I'm an expert in medical imaging with a focus on ultrasound technology. I'm here to provide you with a detailed explanation of what is checked during an abdominal ultrasound.
An abdominal ultrasound, also known as a sonography, is a non-invasive diagnostic test that uses high-frequency sound waves to create images of the internal organs within the abdomen. This test is commonly used to evaluate a variety of conditions and to provide a visual representation of the organs' structure and function. Here's a comprehensive overview of what is typically checked during an abdominal ultrasound:


1. Liver: The liver is one of the most scrutinized organs during an abdominal ultrasound. It is examined for size, shape, and the presence of any lesions, such as cysts, abscesses, or tumors. The ultrasound can also detect signs of cirrhosis, fatty infiltration, and other abnormalities.


2. Gallbladder: The gallbladder is assessed for gallstones, polyps, inflammation (cholecystitis), and tumors. The ultrasound can also determine if the gallbladder is functioning properly by checking for the presence of bile and evaluating its contractility.


3. Spleen: The size and shape of the spleen are evaluated, along with the detection of any enlargement (splenomegaly), cysts, or masses. The ultrasound can also reveal signs of trauma or infarction.


4. Pancreas: The pancreas is examined for its size, shape, and the presence of any lesions or inflammation (pancreatitis). The ultrasound can also be used to guide biopsies or drainage procedures if necessary.


5. Kidneys: The kidneys are checked for size, shape, and the presence of stones, cysts, tumors, or signs of infection. The ultrasound can also assess the renal blood flow and detect any obstructions in the urinary tract.


6. Blood Vessels: The ultrasound can visualize the blood vessels, such as the aorta and the inferior vena cava, to check for aneurysms, thrombosis, or other vascular abnormalities.

7.
Abdomen Aorta: The abdominal aorta is specifically examined for aneurysms, which are bulging or dilation of the aortic wall, which can be life-threatening if they rupture.

8.
Retroperitoneal Space: The retroperitoneal space, which lies behind the peritoneum, is assessed for any masses or abnormal fluid collections.

9.
Urinary Bladder: Although not always included in a standard abdominal ultrasound, the urinary bladder can be examined for residual urine, stones, tumors, or other abnormalities.

10.
Adrenal Glands: Sometimes, the adrenal glands are also visualized to check for tumors or enlargement, especially in cases where an endocrine disorder is suspected.

1. Intestines: The intestines are not typically well visualized with ultrasound due to the presence of gas, but in certain cases, the ultrasound can provide information about the intestinal wall or detect conditions like intestinal obstruction.

2. Pelvic Organs: In some cases, the pelvic organs such as the uterus and ovaries in females or the prostate in males may be included in the ultrasound if indicated by the clinical presentation.

It's important to note that the specific organs and areas examined during an abdominal ultrasound can vary based on the patient's symptoms, medical history, and the referring physician's request. The ultrasound is a dynamic process, and the radiologist or sonographer may focus on different areas based on the findings as the examination progresses.

Now, let's proceed with the translation into Chinese.

Abdominal ultrasound is a type of imaging test. It is used to look at organs in the abdomen, including the liver, gallbladder, spleen, pancreas, and kidneys. The blood vessels that lead to some of these organs, such as the inferior vena cava and aorta, can also be examined with ultrasound.Jul 3, 2016read more >>
