In which quadrant do you inspect for the spleen during a FAST examination?

During a Focused Assessment with Sonography for Trauma (FAST) examination, the spleen is inspected in the left upper quadrant of the abdomen. This is because the spleen is located in that specific quadrant, situated posterior to the stomach and adjacent to the left kidney and diaphragm. The left upper quadrant is the area where sonographers look for abnormalities, injuries, or free fluid that may indicate splenic trauma or other pathologies involving the spleen. The importance of identifying issues with the spleen during trauma evaluation is critical, as splenic injuries can lead to significant bleeding and may require surgical intervention.
