Research workflows
Research-stage imaging workflows for volume reports and longitudinal follow-up.
Cardiothoracic Ratio (CTR)
Measure CTR from chest CT or MRI by comparing the widest horizontal diameter of the heart with the width across both lungs.
Liver Fat Fraction Workflow
Measures liver fat fraction from qualified PDFF, Dixon water/fat, or in-phase/opposed-phase MRI series using a dedicated liver analysis service.
PKD Workflow
Measure kidney and cyst volumes, classify Mayo class 1A-1E, and track growth over time for PKD.

Reassessing the Cardiothoracic Ratio (CTR): From a Chest X-ray Index to Opportunistic Cardiac Screening on Abdominal MRI in ADPKD
The cardiothoracic ratio is a century-old chest X-ray index of heart size. Recent work (Shen et al., JMRI 2026) shows it can be measured directly on the abdominal MRI that ADPKD patients already undergo for kidney-volume monitoring, to identify left ventricular hypertrophy. This article reviews the measurement and diagnostic performance of the CTR, focuses on its value for opportunistic cardiac screening in ADPKD, and discusses the shift toward automated, quantitative imaging.
