Paper Summary:

The paper explains that multislice CT angiography is a potentially useful and cost-effective, non-invasive diagnostic modality. The paper discusses multislice angiography's diagnostic accuracy in different diseases, including cerebral vascular disease, aneurysms, pulmonary embolism, coronary artery disease and peripheral vascular disease. The paper also points out that multislice CT angiography's technology is quickly outpacing the conventional angiography. The paper notes, however, that some surgeons still prefer the time-tested angiography in spite of its invasive nature, discomfort to the patient and potential risk for hemorrhage.

From the Paper:

"Conventional angiography is considered as the golden standard technique in vascular imaging. Its main attributes include real-time visualization of target vessels, which makes it ideal not only for direct visualization of the vasculature of any accessible organ, but also for conducting therapeutic procedures. This provides angiography procedures with the distinct advantage of being able to diagnose and treat vascular diseases with one procedure. This comes at a cost. Another main attribute of angiography is its invasive nature. Most procedures involve gaining vascular access through the femoral artery, which presents as a potential problem post-procedure. While local pressure and close post-procedure monitoring can prevent life-threatening hemorrhaging, subjecting patients to seemingly unnecessary invasive procedures has prompted the development of other imaging modalities to match the real-time precision of angiographic imaging as well as remain non-invasive."
