text: Yo, check it out, recent tech's been kickin' it real fly,
  Them image processing systems, they takin' us high,
  Now we can compute angiocardiographic image series,
  Acquiring and displayin' cardiac parameters with ease.
  
  The basic mode we use is repetitive image subtraction,
  Capturin' left ventricular wall motion, no distraction,
  We document abnormalities in the smoothest way,
  Qualitative organ perfusion, color-codin' DSA-images play.
  
  But when it comes to vascular perfusion, we go deep,
  Quantitative studies, complex techniques, no time to sleep,
  Indicator dilution theory, extractin' parameters so right,
  Advancements in arterial flow measurements, pure insight.
  
  Peripheral vascular disease, we study its flow distribution,
  Makin' progress, no room for confusion,
  In cardiology, the focus is on coronary flow reserve,
  Perfusion time or contrast mass, that's what we observe.
  
  But hey, let's not forget the limitations we face,
  Physico-chemical effects of contrast media in this chase,
  Quantitative flow studies, we gotta keep it real,
  Considerin' these factors, that's the deal.
