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.…

Impact of tube voltage on image quality and radiation dose in CT coronary angiography: a comparative study of 100 vs 120 kVp protocols
Introduction In CT coronary angiography (CTCA), balancing image quality with patient safety is essential. This observational study from Kasturba Hospital, Manipal, investigates how tube voltage—specifically 100 kVp versus 120 kVp—affects image quality and radiation exposure. By tailoring voltage to body mass index (BMI), researchers aim to achieve diagnostic-quality images while minimizing radiation dose. Study design…
