Deep Learning for Synthetic Postcontrast T1-Weighted MRI: A Systematic Review With Targeted Meta-Analysis of Brain Tumor Studies

BACKGROUND . Gadolinium-based contrast agents remain essential for MRI but carry risks. Deep learning (DL) methods have emerged as a potential approach for synthesizing postcontrast T1-weighted images from precontrast sequences alone. OBJECTIVE . The objective of the present study was to systematically review DL-based synthesis of postcontrast T1-weighted MRI, characterize model architectures and evaluation practices across subspecialties, and perform targeted meta-analysis where sufficient literature existed. E…

Current reading — gain

Systematic review and meta-analysis of 15 brain tumor studies found deep learning synthesis of postcontrast T1-weighted MRI from precontrast sequences alone is technically feasible with high whole-image similarity.

Current reading — problem

Clinical translation is limited by inconsistent evaluation, substantially lower performance on pathology-specific regions, and reliance on single-institution data with few reader studies or external validation.

What this doesn’t fix

Pooled performance estimates are descriptive only due to extreme heterogeneity and inconsistent metric computation, and most studies lacked external validation and reader studies.

How to verify without trusting this page

Fetch the canonical text of any version from /api/record/TRV-2026-0904 and hash it yourself — for example shasum -a 256 on the saved canonical field. The result must equal content_hash, and each version’s text ends with prev:followed by the prior version’s hash (version 1 chains to 64 zeros). If a single character of any version had been altered since certification, the chain would not reproduce.
