Figure 1. A showcase of different types of intracoronary thrombi visualised with high-definition intravascular ultrasound. A) Acute thrombus (asterisk) with a bright appearance, sharp delineation and no signal attenuation. B) Acute thrombus on the tip of the intravascular ultrasound (IVUS) catheter (arrows). C) Subacute thrombus with a light to dark grey appearance, white speckles and less clear delineation (arrows). D) 360 degrees of subacute thrombus with severe signal attenuation. E-F) Organised thrombus (asterisks) with a homogeneous dark appearance starting from the lumen wall, sharp delineation and in some cases mild signal attenuation. G-H) Thrombus protrusion (arrows) visualised as a lobulated light ...
