This chapter introduces the subject of cardiac catheterization. It starts with background, basic definitions, and a history of the discipline. Indications for both cardiac catheterization and coronary angiography are explored, and the choice between cardiac computed tomography or invasive angiography is discussed. Radiology equipment is explained, along with fluoroscopy and acquisition in terms of optimizing the diagnostic picture with the lowest practicable dose. Following that, radiation safety and protective measures are defined, along with ALARA (‘as low as reasonably achievable’) and dose excess. Finally, preparation of both the patient and the catheter laboratory are covered.
