A catheter for mapping vulnerable plaque deposits within a blood vessel, comprising;

• an elongate shaft having a proximal end and a distal end;
• a plurality of cowls radially disposed about the elongate shaft proximate the distal end thereof;
• each cowl defining an inlet port, an outlet port, and a flow channel extending therebetween;
• and
• a temperature sensor disposed within each flow channel.
