Final answer:
The primary advantage of angiography in cardiovascular imaging is its ability to offer therapy during the diagnostic procedure and its high contrast resolution. It is superior to other imaging methods in providing real-time treatment options and detailed vascular visuals.
Step-by-step explanation:
A primary advantage of angiography for imaging of cardiovascular pathology is that it offers the opportunity to provide therapy at the same time (d). This technique not only allows for detailed images of the vascular system but also enables the interventionist to perform procedures such as angioplasty or stenting during the diagnostic phase, which can be life-saving. Additionally, angiography generally demonstrates high contrast resolution (c), which is particularly useful for visualizing blood vessels and detecting any blockages or other abnormalities as seen in Figure 19.16 with the atherosclerotic coronary arteries.
Refinements in medical imaging technologies have increased the capabilities of angiography over traditional methods such as X-rays, which provide only two-dimensional images from a single angle. In comparison to other imaging technologies like CT, MRI, and PET scans, which give detailed static or functional images, angiography stands out for its high-resolution imaging combined with interventional capabilities.
