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…

Selecting Optimal Imaging Modalities for TAPVC Visualization
Overview: Why Imaging Modality Choice Matters in TAPVC Visualization Total anomalous pulmonary venous connection (TAPVC) is a rare congenital heart defect in which pulmonary veins do not drain into the left atrium as expected. Accurate TAPVC imaging is essential to classify the drainage pattern, assess obstruction, and guide surgical planning. Because TAPVC anatomy can vary…
