Low kV is robust tool for reducing radiation dose from CT scans. There are significant clinical implications when lowering kV in abdominal imaging. Knowledge of these issues is essential for successful implementation of low kV CT imaging of the abdomen. The aim of this abstract is to provide a thorough review of the potential benefits that can be derived from low kV imaging of the abdomen including improved lesions conspicuity, improved contrast to noise ratio in CT angiography and lower dose of contrast material. We will also review the pitfalls associated with low kV imaging.  

• Basic principles of low kV CT imaging • Effect of low kV on noise, image quality, CNR, radiation dose • Implementing reduced tube voltage in abdominal imaging • Clinical applications of low kV imaging in abdomen • Reducing intravenous contrast using low kV imaging. How? When? • Potential drawbacks of low kV imaging including photon starvation and image noise, potential missed vascular pathology and effect on lesion characterization based on density measurements
