A study found that false-positive findings were common in cardiovascular imaging using dual-energy computed tomography (DECT) in patients with gout. Researchers compared non-electrocardiogram (ECG)-gated DECT pulmonary angiograms in patients with and without gout, finding artifacts that could be mistaken for vascular monosodium urate (MSU) deposits. Factors such as motion, foreign bodies, and contrast medium mixing contributed to misinterpretations. To minimize false-positive results, researchers recommended avoiding certain imaging techniques and screening out patients with certain characteristics. Understanding common artifacts in DECT imaging is important for future studies on vascular MSU deposits in patients with gout.
