The primary indication for performing a CT angiogram is to assess vascular diseases or blockages. This imaging technique utilizes computed tomography to produce detailed images of blood vessels, making it particularly effective for identifying conditions such as aneurysms, stenosis (narrowing of the vessels), or occlusions (blockages) in arterial or venous systems. A CT angiogram can visualize the blood flow and highlight abnormalities that might not be visible with standard X-rays or even conventional angiography.

The detailed cross-sectional images obtained during this procedure allow healthcare professionals to evaluate the condition of the arteries and veins, guide treatment decisions, and plan for surgical interventions if necessary. This capability is essential given the critical role vascular health plays in numerous diseases and conditions. The other options suggest diagnostic needs in areas that do not align with the intended use of a CT angiogram, such as evaluating bone fractures, diagnosing tumors in soft tissues, or assessing lung conditions. Each of those areas typically requires different imaging modalities better suited to those specific diagnostic needs.
