Spiral CT Diagnostic Value in Pulmonary Nodule to Assess Growth and Malignancy Status

Objective To determine the accuracy of Spiral tomographic (SCT) measurements of small pulmonary nodules to assess growth and malignancy status. Methods The authors performed repeat SCT of 5 nodule phantoms of various sizes and shapes to assess the accuracy of the measurement technique including nodule diameters、areas and volumes. They then used this technique to assess 65 pulmonary nodules (34 malignant, 31 benign) in patients who underwent repeat SCT as part of their routine clinical protocol, the final d...
