For training models for segmentation, you need to have manually segmentations as input (it is not enough to have just the CT volume). The more data the better, but a few hundred should be enough. If you only have a few ten cases, it may be feasible, too, but it makes the training more difficult (you may need to tune network structure and learning parameters more carefully, do more sophisticated data augmentation, etc.).
