Professor Jin Mo Goo's research lab specializes in thoracic radiology and medical imaging, focusing on the accurate diagnosis and characterization of pulmonary lesions using advanced imaging techniques such as FDG-PET and CT. The lab investigates the radiological features of benign and malignant lung nodules, including ground-glass nodules and tuberculomas, with an emphasis on improving diagnostic accuracy and reducing overdiagnosis. Key research directions include nodule volume measurement optimization, the role of imaging biomarkers in lung adenocarcinoma, and the identification of radiological signs associated with underlying lung diseases such as emphysema and tracheal diverticula. The lab's work bridges clinical radiology and pathological outcomes, aiming to enhance patient management through precise imaging interpretation.

Pulmonary tuberculoma commonly causes an increase in FDG uptake. These results suggest that in geographic regions with a high prevalence of granulomatous lesions, positive FDG PET results should be interpreted with caution in differentiating benign from malignant pulmonary abnormalities.
The most probable nature of a right paratracheal cyst in the thoracic inlet is tracheal diverticulum with a narrow stalk. The presence of a right paratracheal air cyst on CT could be a sign of obstructive lung disease clinically and of the presence of emphysema radiologically.
For accurate measurement of lung nodule volume, it is critical to select a section thickness and/or segmentation threshold appropriate for the size of a nodule.
GGNs can serve as imaging biomarkers that represent the bronchioloalveolar carcinoma component in adenocarcinoma on histology and indicate a better prognosis in patients with lung adenocarcinoma. The evolution of GGNs reflects the multistep progression of adenocarcinoma. Despite the high probability of malignancy of GGNs, the possibility of overdiagnosis should be considered in the management of GGNs.
