Invasive vs. Non-invasive of the Cerebrovascular Circulation: Which Modality Wins?
Hypothesis
Arteriography is the most reliable form of imaging in the diagnosis of cerebrovascular conditions.
Methodology
Medical reports for 41 patients who underwent arteriogram(s), CAT scan(s) and/or MRI(s) for diagnosis of various cerebrovascular conditions between July 2008 and June 2009 at Lakewood Hospital were reviewed and compared. The effectiveness of each test's ability to conclude with the correct diagnosis was based on the majority of concurring diagnoses from prior and subsequent studies. Out of 46 CAT scans, 34 resulted in a correct diagnosis, a 73.9% rate of correct diagnosis. Out of 54 MRIs, 45 resulted in a correct diagnosis (83.3%). Of 48 arteriograms, 47 resulted in a correct diagnosis(97.9%).
Outcomes
Arteriography was found to be the most effective test for diagnosing cerebrovascular conditions. When diagnosing aneurysms, arteriography was found to be the most effective, with a 100% rate of correct diagnosis. This is compared to 90% rate of correct diagnosis for CAT scan and 88.2% rate for MRI. When diagnosing cerebrovascular conditions, all three forms of imaging are important to reach the correct diagnosis, but arteriography should be considered the deciding factor when conflicting results occur.
