1. Correct Answer: B. A: liver, B: gastric antrum, C: pancreas, D: aorta
Rationale: In Figure 68.1, a low-frequency curvilinear probe was utilized to obtain this sagittal plane image. Utilizing familiar surrounding structures such as the aorta (D) and liver (A) can be helpful in identification of the gastric antrum (B) when learning gastric ultrasound. The pancreas (C) frequently appears as an echogenic structure deeper to the gastric antrum. The superior mesenteric artery is frequently captured when obtaining gastric ultrasound images; however, it does not appear in this particular image.
