Hi doctor,

Does MRA show arterioles? Does CTA show small vessels? Can SPECT tell microvasculitis from vasospasm in microvessel? Do arterioles and capillaries feel pain?

Hi,

Welcome to icliniq.com.

I have read through your query in detail. Please find my observations below.

  • A machine having high power magnet might be able to show arterioles in MRA (magnetic resonance angiography).
  • A CTA (Computed tomography angiography) might show small vessels but not exactly arterioles.
  • Pain is a sensation that is understood by the brain and it can have a source in arterioles and capillaries.
