Philosophy of Care

I believe that it is both a privilege and an opportunity that God has given to us in taking care of people who are sick and suffering and thus I believe in bringing excellence to this mission.

Clinical Interests

Dr. Lamba is an abdominal radiologist who practices the entire spectrum of abdominal imaging. His areas of interest and expertise are Computed Tomography and Non-Vascular Interventional procedures in the abdomen and pelvis (such as biopsy of tumors and drainages of abscesses). He is an expert in diseases of the pancreas, small bowel, liver, aorta, and in CT (Virtual) Colonography.

Research/Academic Interests

Dr. Lamba's research intersts are in the optimization of radiation doses for CT exams. His educational intersts are in pancreatic, small bowel, aortic, and vascular diseases. He also has an interest in the application of Business and Finance models to the radiology practice and in Strategy development.
