Healthcare Annotation FAQs

Common questions about our medical annotation services

Yes, we are fully HIPAA compliant with BAA agreements, end-to-end encryption, secure data storage, and strict access controls. All annotators undergo HIPAA training and sign confidentiality agreements. We maintain comprehensive audit trails and never store PHI beyond project completion.

Our annotation team includes board-certified radiologists, licensed medical imaging technologists, and clinical specialists with 5+ years of experience. All annotators have specific training in the imaging modalities they label (CT, MRI, X-ray, ultrasound, pathology) and undergo continuous quality calibration.

We support all standard medical imaging formats including DICOM (CT, MRI, X-ray, ultrasound), NIfTI, NRRD, whole slide imaging formats (SVS, NDPI, TIFF), and proprietary formats. We can handle both 2D images and 3D volumetric data with multi-planar reconstruction.

Every annotation undergoes multi-tier validation: initial labeling by certified specialists, peer review by a second radiologist, and final validation against clinical ground truth when available. We achieve 99.9% accuracy through consensus annotation protocols and regular inter-rater reliability testing.

Yes, our network includes subspecialty radiologists across all major medical domains (neuroradiology, musculoskeletal, oncology, cardiology, etc.). We have experience with rare pathologies, atypical presentations, and challenging cases that require specialized clinical knowledge.

We provide comprehensive medical annotation including semantic segmentation (organ/tumor boundaries), instance segmentation (individual lesions), bounding boxes (nodule detection), polygon annotation (irregular structures), landmark annotation (anatomical points), classification labels (disease presence), and 3D volumetric annotation for CT/MRI series.
