Ground-glass nodule features on CT reveal malignancy risk
By Eric Barnes
Researchers are peering through a proverbial glass, darkly, to study the features of ground-glass opacities (GGOs). GGOs are being detected with increasing frequency as more thin-section CT lung scans are performed to check for cancer in smokers and former smokers. Distinguishing benign from malignant GGOs is a hit-or-miss task for CT, one that could potentially improve if researchers are able to find reliable signs of malignancy or benignity, thereby reducing the need for invasive biopsy.
