Post-Radiotherapy Brain MRI Data for 38 Nasopharyngeal Carcinoma Patients

38 post-radiotherapy nasopharyngeal carcinoma patients and 23 healthy controls underwent T1-weighted MRI scans to assess radiation-induced brain structural changes. Chunhong Qin authored this study, which applies causal structural covariance network analysis to morphometric data ordered by time post-treatment. The dataset, last updated in April 2026, is a 21.1 KB document detailing the analysis of source-like and sink-like brain regions.

Use Cases

• Modeling causal relationships in brain structural alterations based on Granger causality analysis mentioned in the description.
• Identifying source-like brain regions (e.g., parahippocampal gyrus) that regulate gray matter volume changes in post-radiotherapy patients.
• Analyzing the temporal progression of gray matter damage ordered by time elapsed post-radiotherapy.
• Comparing structural covariance networks between patient and healthy control groups using MRI-derived morphometric data.

Strengths

• Includes a specific cohort of 38 post-radiotherapy patients with detailed demographics (median age 50.0 years, 33 males, 5 females).
• Provides a control group of 23 healthy individuals for comparison.
• Analysis is based on a concrete methodological approach: causal structural covariance network (CaSCN) and Granger causality analysis.
• Data is ordered by a clear temporal variable: time post-radiotherapy (median 17.2 months, range 0.5–108 months).

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• The dataset is very small (21.1 KB), suggesting it contains summary analysis or metadata rather than raw image data.
• Description metadata is limited; actual data quality and structure require manual inspection of the DOCX file.
