I wanted to download AlexNet and VGG-16 CNN models that have been pre-trained on medial images. It could be pre-trained for any particular mdeical image related task like segmentation, recognition, etc. It should preferably handle medical images of various modalities. Are there any such models which are publicly available?
Why do you need to be trained on medical images?
If you don't want to train a neural network at all, then you need an architecture for a specific task. And if you plan to train on your data, then there is no big difference, the network is pre-trained on medical images or not. The first layers of the convolutional neural network are trained to identify low-level patterns that can be found in medical images.
I think. that applying ResNet with ImageNet weights, with the last layers re-learning on their data, would be a good start.
Hi Diana T Miranda ,
There are a number of ImageNet large scale databases for visual recognition, etc.
Check this one and see if you can download the data:

Also check the following papers to see if you may contact the authors or access the data:

Article Very Deep Convolutional Networks for Large-Scale Image Recognition

Thank you Mark Panenko and Bahman Sadeghi for taking time to answer my query.
I have already worked with CNNs which are pretrained on ImageNet. I have performed fine-tuning as well as retrained the entire CNN using medical images.
I now want to compare those results with those obtained using a CNN which is trained on medical images. However, currently I do not have sufficient resources to do this. Hence, I need a CNN which is pre-trained on medical images.
Short answer, there is not, and even if you find one, on which medical imaging modality do you want it to be pre-trained (e.g., MRI, X-ray, ultrasound, SPECT, PET)?
I want it to be trained on multiple modalities. I'm working on handling images of various modalities. So I wanted the CNN to be able to handle all of them or atleast majority of them.
