Question

Which of the following cardiac exam techniques provides the best spatial resolution of the cardiac structures?

A) Resting echo with contrast
B) Transesophageal Echo
C) Cardiac catheterization
D) Stress Echo

Answer 1

Cardiac catheterization provides the best spatial resolution of cardiac structures among the given options.

Step-by-step explanation:

The question asks us to determine which cardiac exam technique provides the best spatial resolution of cardiac structures. When it comes to spatial resolution, which refers to the ability to distinguish small or closely spaced structures, the answer is C) Cardiac catheterization. This procedure allows for very detailed visualization of the heart's anatomy, including its chambers, valves, and blood vessels. It is more invasive compared to techniques like echocardiography but offers superior spatial resolution.
