Thoracic Imaging for Medical Students

Thoracic radiology focuses on the diagnosis and assessment of cardiac and pulmonary diseases. Radiography plays a major role in lung imaging, and its chest radiographs are one of the most common radiologic exams in modern medicine. CT is also being more commonly used in imaging the lungs and heart, especially with the recent interest in low dose CT scans for lung cancer screening. While MRI is not commonly used in imaging the lungs, its use in imaging of the heart is one of the burgeoning fields of radiology. In imaging the lung, thoracic radiologists work closely with intensivists, pulmonologists, cardiothoracic surgeons and pathologists. Thoracic radiologists work closely with cardiac surgeons and cardiologists in imaging the heart, and often co-interpret cardiac studies with cardiologists.
