Lesion Detection Performance: Comparative Analysis of Low-Dose CT Data of the Chest on Two Hybrid Imaging Systems

Abstract: Incidental findings on low-dose CT images obtained during hybrid imaging are an increasing phenomenon as CT technology advances. Understanding the diagnostic value of incidental findings along with the technical limitations is important when reporting image results and recommending follow-up, which may result in an additional radiation dose from further diagnostic imaging and an increase in patient anxiety. This study assessed lesions incidentally detected on CT images acquired for attenuation correction on tw… Show more

“…These results were reproduced in a study using the same chest phantom on two different SPECT/CT systems. Here, lesion detection was more reliable on one system than on the other and was found to be related to the reconstruction algorithms used on one of the CT units rather than the acquisition parameters (25). The phantom was stationary in all studies and so did not truly represent the clinical situation in which motion artifacts from breathing would degrade the attenuation-correction CT images.…”
