Prospectively gated CT scans are as effective as standard tests when it comes to ruling out heart problems, a study published in the Annals of Internal Medicine has reported.
Researchers analysed prospectively gated CT scans as well as catheter coronary angiography — the current gold standard — in 16 earlier studies involving a total of 960 patients.
Researchers found out that prospectively gated CT scans ruled out heart problems as effectively as the gold standard test.
Although the CT scans led to 11% more false positives, researchers noted that those patients would go ahead and have a catheter-based test.
Prospectively gated CT scans cut down the radiation dose to less than 3mSv, compared to 7-9mSv from the catheter test and 12mSv from a standard CT heart scan.
