spinenet 2.0.2

Automated software for analysing clinical spinal MRI scans.

DISCLAIMER: SpineNet is not a diagnostics tool nor a medical device. It should only be used for research.

Introduction

SpineNet is automated software for analysing clinical spinal MRI scans. Current functionality includes:

1. Detecting and labelling vertebral bodies in sagittally-sliced MRI scan across a range of common sequences (e.g. T1, T2, STIR etc.) and fields of view (lumbar, cervical, whole spine).
2. Performing radiological grading at each intervertebral disc level in T2 lumbar scans from T12/L1 to L5/S1 for a range of common degenerative changes.

As well as using SpineNet for detecting and labelling vertebral bodies and the existing radiological gradings, you can also use the codebase for finetuning the model to perform additional gradings. For example, we have previously adapted it to detect vertebral fractures, cauda equina, ankylosing spondylitis and other diseases.

Please note that by using SpineNet you agree to our terms of access. Amongst other things, this prohibits the use of SpineNet for commercial purposes. If you wish to acquire a more permissive licence of SpineNet, please contact us.

Getting Started

SpineNet's documentation is available here

Install enviroments

A minimal python environment for running SpineNet can be found in requirements.txt and can be installed used

$ python -m venv spinenet-venv
$ source spinenet-venv/bin/activate
$ pip install -r requirements.txt

Running The Code

Clone the repository and add the root directory to your PYTHONPATH, e.g. via

$ export PYTHONPATH=$PYTHONPATH:/path/to/SpineNet

When using SpineNet for the first time, you first must download weights from the VGG public server, by calling the function

spinenet.download_weights(verbose=True)

or to re-download them:

spinenet.download_weights(verbose=True,force=True)

For a guide on using SpineNet, see the 01-quickstart.ipynb tutorial notebook.
