Professor Shin-ichi Izumi's research lab specializes in diagnostic imaging and interventional radiology, with a primary focus on advancing ultrasound-guided procedures for accurate and safe tissue diagnosis in thoracic diseases. The lab emphasizes the development and clinical application of innovative imaging techniques, such as ultrasonically guided aspiration needle biopsy, to improve early detection of lung and chest wall pathologies. Their work centers on enhancing diagnostic accuracy while minimizing patient risk through precise, real-time imaging guidance. The lab also contributes to the refinement of minimally invasive diagnostic methods in pulmonology and chest radiology.

Ultrasonically guided aspiration needle biopsy has been used in our department as a diagnostic procedure in chest disease. Twenty patients with chest disease judged to have lesions abutted to the thoracic wall were selected as candidates for this technique, which was a linear electronic array scanner provided with a specially designed guide channel. In all sixteen patients with malignant disease, this method provided biopsies that yielded malignant cells on cytologic examination. The diagnostic
