Deep-Learning Detection of Cancer Metastases to the Brain on MRI.

ABSTRACT:

Background

Approximately one-fourth of all cancer metastases are found in the brain. MRI is the primary technique for detection of brain metastasis, planning of radiotherapy, and the monitoring of treatment response. Progress in tumor treatment now requires detection of new or growing metastases at the small subcentimeter size, when these therapies are most effective.

Purpose

To develop a deep-learning-based approach for finding brain metastasis on MRI.

Study type

Retrospective.

Sequence

Axial postcontrast 3D T₁ -weighted imaging.

Field strength

1.5T and 3T.

Population

A total of 361 scans of 121 patients were used to train and test the Faster region-based convolutional neural network (Faster R-CNN): 1565 lesions in 270 scans of 73 pati
