Dear HCP Users,
I am writing to seek expert advice on a deep learning project involving MRI image classification. Given the esteemed expertise in MRI image interpretation within this group, I believe your insights would be invaluable.
I am working with an MRI dataset comprising 16 image slices per subject, divided into 'sick' and 'healthy' categories.Importantly, the MRI modality (T2, T1, or FLAIR) varies across subjects, regardless of health status.
My goal is to develop an accurate deep learning algorithm capable of classifying MRI images as either 'sick' or 'healthy.' In light of this, I would like to pose two questions:
Considering the heterogeneity of MRI modalities, would it be advantageous to train separate models for each modality, or is a unified model capable of handling all modalities more suitable?
Should the model process all 16 slices as a tensor, or would focusing on a single slice (e.g., the deepest) be more effective?
I eagerly anticipate your valuable perspectives and suggestions. Thank you for your time and consideration.
