Just as Sir Jagadish Chandra Bose believed that “The true laboratory is the mind, where behind illusions we uncover the laws of truth,” Dr Kushaljit Singh Sodhi in his presentation conveyed that it is imperative to explore the true potential of the MRI tool in lung imaging among children.
He spoke about how MRI can be effectively utilised in lung scans among children. He presented various case studies that examine certain areas in which MRI can be utilised instead of a CT. He shared examples in which an MRI can become the first line of diagnostic modality in certain lung examinations which can have a better diagnosis. He also spoke of the challenges associated with MRI which include low tissue density, susceptibility differences between tissue and air and tissue motion because of respiration and cardiac motion. He further urged radiologists to ensure that these challenges don’t hinder the examination.
Dr Sodhi then highlighted different MRI parameters, such as slice thickness, flip angle, TE, TR, the field of view, plane, matrix, averaging phase overlapping, slices, phase encoding direction and phase oversampling, etc. He shared his experience and pointed out some intrinsic parameters of each MRI sequence. Further on, he shared examples of applications of MRI in the paediatric thorax.
Highlighting certain areas of illnesses in which MRI can be very effective in detecting childhood pneumonia and pulmonary infections, HIVs, leukemia and more. He additionally summarised the clinical indications of MRI v/s CT.
Dr Sodhi concluded his presentation by pointing out that lung MRI is technically feasible, radiation-free imaging modality. A rapid lung MRI is possible in less than two minutes. More studies and technological advances are required to validate the role of MRI. It has the potential to be a game-changer paediatric thoracic imaging in the coming years.
