Ans In medical imaging balance between imaging speed and signal to noise ratio depends on many factors I will describe this aspect taking cardia MRI scan as an example which is more difficult and highly error prone compared to CT and Ultrasound scanning In cardiac MRI the tradeoff between imaging speed and Signal to Noise Ratio is very important because it is performed on beating heart and breathing lungs Usually this technique is always performed corresponding to the techniques like ECG To acquire less SNR Morphological single time frame images are commonly acquired by acquiring multiple data samples during middiastole when the heart has minimal motion This will have relatively long temporal window with minimal motion artifacts resulting in a shorter acquisition time For functional time resolved data the tradeoff between
