Left Lateral Flank

Left high flank section in right lateral decubitus position

LA, suprapubic

Right intercostal flank section in left lateral decubitus position

Try to think which organs appear in which sonographic sections

The solutions can be found overleaf.

Standard Sonographie Sections with Corresponding Transducer Positions

The most important organs and vessels that are seen in the various standard sonographic sections are listed here. In addition to remembering the corresponding body landmarks, the names of the sonographic sections should be memorized

(UA = upper abdomen; MA = mid-abdomen; MCL = midclavicular line; LA = lower abdomen). Each imaging plane should be closely scrutinized using sweeping motions of the transducer.
