Erythrocytes at various concentrations were examined with a sensitive A-mode ultrasonic scanner; simultaneous measurements were made under light microscopic control. Individual erythrocytes caused weak (about 1 dB) echoes while erythrocyte aggregates (ten to 100 cells) produced stronger echoes (up to 15 dB), grossly proportional to the size of the aggregates. The latter type echoes were characteristic of higher erythrocyte concentrations (hematocrit 0.1 - 0.8). It is concluded that these echoes originate from red cell aggregates within the stagnant blood.
