Which primary organs are typically assessed during an abdominal ultrasound?

The primary organs typically assessed during an abdominal ultrasound include the liver, kidneys, gallbladder, pancreas, spleen, aorta, and inferior vena cava. This selection encompasses major components of the abdominal cavity crucial for evaluation of various gastrointestinal, vascular, and organ-specific conditions.

The liver and kidneys are commonly examined to detect pathologies such as tumors, cysts, fatty changes, or kidney stones. The gallbladder is assessed for gallstones and inflammation, while the pancreas is evaluated for pancreatitis or tumors. The spleen can provide information regarding hematological conditions or organomegaly. Additionally, the aorta and inferior vena cava are assessed during abdominal ultrasounds to evaluate the presence of aneurysms or obstructive conditions.

Other options listed include organs that are either not primarily assessed in abdominal ultrasounds or focus on too few organs. For instance, assessing the heart and lungs is more pertinent to a cardiac or thoracic ultrasound. Focusing solely on the gallbladder, pancreas, and small intestine or stomach and esophagus reduces the scope of assessment, neglecting other critical abdominal structures. Thus, option A correctly identifies the comprehensive list of primary organs evaluated during standard abdominal ultrasound examinations.
