ClearRead CT
Overview
ClearRead™ CT by Riverain Technologies is a cardiothoracic AI suite designed to enhance the accuracy and efficiency of disease detection in chest CT scans. It leverages advanced AI algorithms and patented vessel suppression technology to provide an unimpaired view of the lung, aiding radiologists in identifying and characterizing pulmonary nodules and assessing coronary artery calcification (CAC).
The suite comprises several powerful tools: ClearRead CT Vessel Suppress, which removes vessels and other normal structures to improve nodule conspicuity; ClearRead CT Detect, which automatically detects, segments, and measures critical properties of solid, sub-solid, and ground glass nodules; and ClearRead CT Compare, which tracks nodules over time and provides precise volumetric change measurements for comparative analysis.
ClearRead CT is proven to reduce total reading time by up to 36% and decrease missed actionable nodules by 29%, easing cognitive burden and improving diagnostic confidence. It seamlessly integrates into existing PACS workflows, supporting concurrent reading without the need for additional hardware or separate viewers. The solution is enterprise-ready, processing scans from all CT manufacturers and acquisition protocols.

What Physicians Need to Know
Leverage ClearRead CT's Coronary Artery Calcification (CAC) scoring on routine, ungated chest CTs to opportunistically identify patients at risk for cardiovascular disease who might otherwise go undetected. This can facilitate earlier intervention and improve patient outcomes by integrating cardiac risk assessment into existing lung cancer screening or other chest CT workflows. The Agatston score and 'arterial age' provide valuable quantitative data for risk stratification.
ClearRead CT outputs findings in DICOM format, making it readable in Picture Archiving and Communication Systems (PACS). It supports seamless workflow with concurrent reading, often integrating as an additional series in the patient study without requiring a separate viewer or logins. ROI contours and measurements can be exported as overlay objects or DICOM SC objects, and pre-populated reports are available.

1 AI-estimated ClearRead CT received FDA 510(k) clearance (K161201) on September 9, 2016, as a computer-aided detection (CAD) system intended to aid radiologists in the detection of pulmonary nodules during review of CT examinations of the chest on an asymptomatic population. It was the first FDA-cleared device to support concurrent reading. More recent clearances (as of February 2025) extend its functionality to include coronary artery calcium (CAC) scoring for ungated, non-contrast CTs. |

What the Web Says
ClearRead CT by Riverain Technologies is an AI-powered software designed to assist radiologists in detecting and characterizing pulmonary nodules in chest CT scans, particularly for lung cancer screening and surveillance. It aims to improve reading efficiency and accuracy by providing an unimpaired view of the lungs through vessel suppression and acquisition normalization technologies. The software integrates with existing PACS systems, allowing radiologists to view processed images alongside original CT series without needing a separate application.
Overall: PositiveStrengths
- Increased nodule detection rates, especially for small nodules (u22642 mm).
- Reduced reading times for radiologists.
- Improved interreader agreement.
- Seamless integration with existing PACS and workflow.
- Easy installation and adaptability to changing CT protocols.
- Ability to quantify incidental coronary artery calcification (CAC) on ungated CT exams.
Limitations
- Limited scientific data on the use of the software at one point, prompting a study to confirm accuracy and efficiency.
- Not intended for monitoring patients undergoing therapy for lung cancer or limited field of view CT scans.
- Provides adjunctive information and is not intended to be used without the original CT series.
- Some general AI services for CT reads have been noted to frequently miss clinically relevant findings outside of specific diagnoses.
- No specific negative reviews found on G2 or Capterra for ClearRead CT, but general concerns about AI in radiology include potential for missed findings and the need for radiologist oversight.
