Abstract

Computed tomography angiography (CTA) is a widely used imaging modality for the diagnosis and evaluation of various vascular diseases. However, the use of iodinated contrast media in CTA poses potential risks, such as contrast-induced nephropathy (CIN), especially in patients with impaired renal function. Therefore, minimizing contrast dose while maintaining diagnostic quality is crucial for patient safety and optimal imaging outcomes. This paper explores various strategies and techniques to reduce contrast dose in CTA, including patient-specific protocols, low-kV imaging, dual-energy CT, and iterative reconstruction algorithms, while ensuring the preservation of diagnostic quality
