Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Brain Imaging

Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

Background:

Deep learning (DL) models, especially Transformers, show promise in analyzing complex medical imaging data for brain tumor prognosis.
However, their effectiveness in predicting post-treatment recurrence remains under-demonstrated.

Purpose of the Study:

Develop and validate a Transformer-based DL model using multi-modal data (pre-treatment MRI and radiotherapy dose).
Predict post-treatment brain tumor recurrence to support personalized radiotherapy decisions.

Main Methods:

Trained and validated a Transformer-based DL model on MRI data from brain metastases patients who underwent Gamma Knife radiosurgery.
Compared the model against nine established prognostic models and validated its generalizability across clinical subgroups.
Utilized logistic regression and statistical analysis to confirm prediction independence.

Main Results:

The Transformer model achieved an AUROC of 0.817, outperforming all other models.
Demonstrated strong generalizability across age and gender subgroups.
Logistic regression confirmed the model's predictions were independent and highly significant (p < 0.001).

Conclusions:

The developed Transformer-based DL model is a reliable prognostic tool for predicting brain tumor recurrence after radiotherapy.
It significantly outperformed existing models, indicating potential for guiding personalized treatment strategies.
This AI approach can enhance decision-making for brain tumor patients receiving radiotherapy.
