Investigation of optimal sample preparation conditions with potassium triiodide and optimal imaging settings for microfocus computed tomography of excised cat hearts.

Objective: To determine optimal sample preparation conditions with potassium triiodide (IKI) and optimal imaging settings for microfocus CT (micro-CT) of excised cat hearts.

Sample: 7 excised hearts (weight range, 10 to 17.6 g) obtained from healthy adult cats after euthanasia by IV injection of pentobarbital sodium.
