Philosophy of Care

I believe in treating patients as if they were family, with respect and empathy, and in the same way I would like to be treated as a patient myself. I believe in a team approach for medical care, and aim at providing the right service every time, the first time. I follow an individual, personalized approach that adheres to best practices and the best available scientific evidence.

Clinical Interests

Dr. Knollmann is a Diagnostic Radiologist who specializes in the diagnosis of cardiovascular and chest disease in adults and children. He has special experitse in Radiography, Computed Tomoraphy, and Magnetic Resonance Imaging of the heart , vessels, and chest, coronary artery disease, and tumors of the chest.

Research/Academic Interests

Dr. Knollmann's research is focused on cardiovascular and chest imaging, following a Humboldtian philosophy of combining scientific research, academic teaching, and clinical care.

Special areas of research include the effectiveness of imaging in diagnosing congenital and acquired heart and lung disease. Recent research includes the noninvasive diagnosis of coronary heart disease and lung cancer.
