Impact of 100 kVp vs 120 kVp in CT Coronary Angiography: Image Quality and Radiation Dose
Overview This study compares two common tube voltage protocols—100 kVp and 120 kVp—in computed tomography coronary angiography (CTCA). Conducted at the Department of Radio Diagnosis and Imaging, Kasturba Hospital, Manipal (June–December 2023), the prospective observational analysis investigates how adjusting voltage by body mass index (BMI) influences image quality and radiation dose. The investigation enrolled 88…

Impact of Tube Voltage on Image Quality and Radiation Dose in CT Coronary Angiography: A Comparative Study of 100 kVp vs 120 kVp Protocols
Introduction and Purpose Computed tomography coronary angiography (CTCA) is a pivotal, noninvasive tool for evaluating coronary artery disease. A key clinical challenge is balancing diagnostic image quality with patient radiation dose. This study analyzes how tube voltage (kVp) affects image quality and radiation dose, comparing 100 kVp and 120 kVp protocols in a BMI-based approach.…
