CT Scan.

Our medical image annotation team has extensive experience working in multislice CT scans to identify and classify muscle disorders, bone fractures, internal bleeding or other injuries, multi-organ segmentation, and benign or malignant tumors. We specialize in image annotations of the head and neck, abdomen, joints, and cartilage.


CapeStart’s MRI annotations include precise contouring and segmentation of cerebral infarctions/ lesions/ hemorrhages/ tumors; vertebrae; the chest, abdominal and pelvic regions; and the joints.

Ophthalmic Imaging.

CapeStart’s ophthalmology team has vast experience preparing and annotating OCT and Fundus Images, including detection of diabetic retinopathy, age-related macular degeneration, glaucoma, retinopathy of prematurity (ROP), congenital cataracts, and retinal vein occlusion.

X-Ray & Mammogram.

X-rays are commonly used to identify congenital deformities of the bone, fractures, tumors, collections of fluid or free air, and tracheal disorders. Our team of radiologists and radiologic technologists have extensive experience annotating and contouring X-Ray abnormalities. 

We’ve also completed a number of mammography annotation projects detecting lesions, masses, and calcifications.
