Optimizing MRI protocols for children

In this video, Dr. Bhargava begins with an overview of key considerations for optimizing MRI protocols and factors to consider when choosing hardware for imaging children. As MRI is dependent on the size of the child, careful consideration is required when choosing coils and the field of view. Selection of the right coil for the application and child allows for optimization of the signal to noise ratio (SNR), leading to better image quality. The higher SNR obtained on 3T magnets is also useful, especially for imaging of small children. The use of 1.5T magnets has its own advantages, including less susceptibility artifact and the availability of certain sequences. As it is difficult for children to stay still for a lengthy exam, attention should be paid to the purpose of different sequences in the protocol and to get to the key sequences as quickly as possible. The second half of the video covers contrast choices and the risks and benefits that must be considered when choosing a contrast agent.

In the upcoming third part of this video series, Dr. Bhargava continues with a discussion of the tolerance of gadolinium based contrast agents in children.
