T2-weighted Kidney MRI Segmentation Dataset

A High-Quality Dataset for Kidney Segmentation in MRI

📌 Overview

This dataset contains 100 T2-weighted abdominal MRI scans with manually segmented kidney masks. The MRI sequence is optimized to enhance the contrast between the kidneys and surrounding tissues, improving segmentation accuracy. It includes scans from:

• ✅ Healthy control subjects
• ✅ Chronic Kidney Disease (CKD) patients

Additionally, 10 subjects were scanned five times in a single session to assess the precision of Total Kidney Volume (TKV) measurements.

📊 Dataset Details

• Total MRI Scans: 100
• Scanned Groups: Healthy & CKD Patients
• Repetitive Scans for TKV Analysis: 10 subjects (scanned 5 times each)
• Data Format: NIfTI (.nii)
• Additional Data: Subject information in CSV file
• Size: 160.3 MB
• Source: UK Renal Imaging Network (UKRIN)

🔍 Use Cases

• ✔️ Deep Learning & AI-based Kidney Segmentation
• ✔️ Chronic Kidney Disease (CKD) Analysis
• ✔️ Medical Imaging Research in MRI

🎈Description

A dataset containing 100 T2-weighted abdominal MRI scans and manually defined kidney masks. This MRI sequence is designed to optimise contrast between the kidneys and surrounding tissue to increase the accuracy of segmentation. Half of the acquisitions were acquired of healthy control subjects while the other half were acquired from chronic kidney disease (CKD) patients. Ten of the subjects were scanned five times in the same session to enable assessment of the precision of Total Kidney Volume (TKV) measurements. More information about each subject can be found in the included csv file. This dataset was used to train a Convolutional Neural Network (CNN) to automatically segment the kidneys.

🔬 Research Potential

This dataset is valuable for AI researchers, radiologists, and biomedical engineers developing CNN-based kidney segmentation models. It has been used in deep learning applications for renal segmentation and can support advancements in functional kidney imaging and CKD research.
