The purpose of this exhibit are;
To demonstrate essential clinical information for the diagnosis of lung nodule
To describe the distribution of imaging findings observed in primary lung cancer, metastasis and benign nodule on thin-slice CT
The knowledge of these nodule characteristics will enhance diagnostic performance of radiologists.
We will present the distribution of well-known imaging findings and clinical information for interpreting lung nodules with figures of representative nodule. The distribution was derived from a large data base constructed by the following method;
One thousand nodules with pathologically or clinically confirmed diagnoses (primary lung cancer or metastasis or benign) were collected.
For each nodule, 37 types of clinical information (e.g. age, sex, smoking history, laboratory data, medical history, etc.) were retrospectively collected.
For each nodule, 51 imaging findings (e.g. shape, spiculation, ratio of GGO, air bronchogram, etc.) were scored based on 2 to 7 point scales by the consensus of two board-certified radiologists.
As an extra analysis, distributions of both imaging findings and clinical information for solid adenocarcinoma and squamous cell carcinoma were also compared for the better interpretation of solid lung nodules.
