# ReadYourLab > AI-powered CT and MRI scan analysis. Upload your DICOM files and get an AI radiology report in minutes. Powered by Google DeepMind's MedGemma and xAI Grok. Try free -- no signup, no credit card required. ReadYourLab (https://readyourlab.com) helps patients understand their CT scans, MRI scans, lab results, bloodwork, and clinical notes using AI. The platform uses a dual-engine AI architecture combining Google's medically-specialized MedGemma 1.5 with xAI's Grok 4.2 Reasoning to deliver accurate, context-aware analysis of medical documents. ## CT and MRI Scan Analysis ReadYourLab analyzes full 3D volumetric DICOM series -- not just single 2D images. Users upload their complete DICOM folder containing .dcm files, and the system automatically organizes them by patient, study, and series. The AI evaluates the full 3D image stack across all slices to provide a reliable radiology report. A typical CT scan has 10-500 .dcm files, and the platform handles both single-slice-per-file and multi-slice-per-file formats automatically. The AI-generated radiology report covers anatomical identification, anomaly detection, and translates medical terminology into plain language. After receiving the report, users can ask unlimited follow-up questions to clarify medical terms, understand findings, get context on how common a finding is, and prepare questions for their doctor. ## Study Summary Report For users who upload multiple scans from one or more studies, ReadYourLab generates a cross-scan study summary report. The summary connects findings across all analyzed CT and MRI series in the account, highlights consistent observations, flags changes between scans, and gives a single complete overview instead of reading each report separately. The summary report is included on the Premium and Family plans. ## AI Models from Google DeepMind and xAI ### MedGemma 1.5 -- The Medical Imaging Specialist MedGemma is the primary engine for interpreting CT scans, MRI images, and clinical data. Developed by Google Research as part of the Gemma family, it is fine-tuned specifically for healthcare. Key capabilities: - **3D Volumetric Processing**: Unlike general-purpose AI, MedGemma understands spatial relationships in three dimensions, identifying the volume and precise location of anatomical anomalies across CT scan slices. - **Medical Instruction Tuning**: Trained on peer-reviewed journals, clinical guidelines, and de-identified electronic health records. - **Top Medical Benchmarks**: Achieves high-tier performance on MedQA (USMLE-style), MultiMedQA, and NEJM Image Challenge. - **Primary Role**: Visual and clinical analysis of medical imaging data. MedGemma scans uploaded documents, identifies medical codes, interprets 3D CT scan data, and flags abnormal values. ### Grok 4.2 Reasoning -- The Logical Engine Grok 4.2 Reasoning from xAI provides the synthesis and reasoning layer. It takes MedGemma's findings and builds clear, easy-to-understand reports using chain-of-thought processing. Key capabilities: - **Reasoning-Heavy Training**: Uses chain-of-thought processing -- the model "thinks" through logical steps and cross-references multiple data points before producing an answer, rather than predicting the next word. - **Synthesis**: Connects findings across lab results, scan data, and clinical notes into a coherent narrative. - **Hypothesis Generation**: Suggests questions to ask your doctor based on combined evidence. - **Complex Logic**: Handles medication interactions and contraindication scenarios. - **Primary Role**: Logic, deductive reasoning, and report generation. Neither ChatGPT nor Grok natively support DICOM file analysis. ReadYourLab uses MedGemma specifically for CT and MRI scan analysis in DICOM format. ## Free Trial The first CT or MRI image series analysis is free. No credit card required. Users can try the service immediately: - 1 free CT or MRI scan analysis - No credit card required - Unlimited follow-up questions - Free scan image viewer (browse all DICOM images) ## Free Online DICOM Viewer and DICOM-to-JPEG Converter ReadYourLab offers a free online DICOM viewer at https://readyourlab.com/pages/free-dicom-viewer.html with the following features: - **100% Free**: No cost, no subscriptions, no hidden fees. - **No Installation**: Works directly in any web browser (Chrome, Firefox, Edge, Safari) on Mac, Linux, and Windows. - **Complete Privacy**: Files are never uploaded to any server.

Users can scroll through 3D image sequences, adjust contrast, view CT or MRI scans online, and save any slice as a JPEG file. ## Free DICOM Anonymizer ReadYourLab offers a free in-browser DICOM anonymizer at https://readyourlab.com/pages/free-dicom-anonymizer.html. The tool strips patient names, patient IDs, birth dates and other PHI from .dcm files before sharing scans. - **100% Client-Side**: Files are anonymized entirely in the browser. Nothing is uploaded to any server. - **HIPAA- and GDPR-Friendly**: De-identification happens on the user's device, so no PHI ever leaves it. - **No Account Required**: No signup, no login. - **Works on Any OS**: Chrome, Firefox, Edge, Safari on Mac, Linux, and Windows. The anonymizer is intended for patients and clinicians who need to share DICOM files (e.g. with another doctor, a researcher, or an AI tool) without exposing personally identifiable information. ## Blog ReadYourLab publishes a patient-friendly blog at https://readyourlab.com/blog with articles about CT and MRI imaging, common conditions, scan preparation, and lifestyle factors. Articles are written for non-radiologists and explain medical concepts in plain language. The blog is available in multiple languages. ## Pricing Flat-fee packages with no subscriptions or recurring charges. Scan analyses never expire. - **Free Trial**: $0 -- 1 CT/MRI scan analysis, no credit card required, unlimited follow-up questions, free DICOM viewer, free DICOM anonymizer - **Personal**: $30 -- 20 scan analyses ($1.50 per scan), analyze all your personal CT/MRI scans, unlimited PDF document uploads, unlimited follow-up questions, free scan image viewer - **Premium** (Most Popular): $40 -- 40 scan analyses ($1.00 per scan), everything in Personal plus priority processing, finding highlights, organ-color view, and a summary report across all scans for a complete overview - **Family** (Best Value): $50 -- 100 scan analyses ($0.50 per scan), for families and recurring cases, includes all Premium features plus the cross-scan summary report Follow-up chat questions are always free and unlimited on all paid plans. Medical document uploads (PDF, JPG) are unlimited for all paid packages. There are no monthly fees -- you pay once and the analyses never expire. ## How to Upload DICOM Files 1. Go to https://readyourlab.com and click "Understand Your CT or MRI Scan" 2. Click "Open CT or MR scan folder" and select the entire folder containing .dcm files 3. The system organizes files by patient, study, and series 4. Click a series card to preview images, then click "Analyze this Series with AI" 5. Receive the AI radiology report and ask follow-up questions Tips: Upload the complete folder (not individual files), extract ZIP archives first, keep folder structure intact, and upload each series separately for best results. ## Data Security - **No third-party data sharing**: Medical documents and personal information are never sold or shared. - **Breach-resistant**: No medical documents are stored long-term; a server breach would not expose medical data. - **No metadata storage**: Extracted information from documents is not stored in databases. - **Encryption**: All data encrypted in transit (SSL/TLS) and at rest. - **HIPAA- and GDPR-aligned** practices. - **Client-side tools**: The DICOM viewer, DICOM-to-JPEG converter, and DICOM anonymizer all run entirely in the browser -- files never leave the user's device.
