This control takes 24h. They are low-contrast black-and-white images full of visual "noise. Her team trained its algorithm to the point that it could trace detailed outlines of abnormalities it found, demonstrating their location in a 3-D model of the brain being scanned. They then tested the algorithm against four board-certified radiologists, using a series of randomly selected head CT scans. The AI slightly outperformed two radiologists, and slightly underperformed against the other two, Yuh said.

September Bleeding, also called haemorrhage , is the term used to describe blood escaping from the blood vessels. Bleeding from the skin occurs if there is an injury to the skin surface, and it may sometimes occur spontaneously. Subungual haemorrhage, or bleeding under a nail plate, results in painful or unnoticed purplish-black discolouration. The discolouration may persist for months as the nail carries the blood with it as it grows out. A bruise, also known as ecchymosis or a contusion, occurs when small blood vessels capillaries under the skin bleed, while the overlying skin remains intact.
The injury causes blood to leak and collect near the skin surface, causing bluish-black skin discolouration. Deeper bruising results in a haematoma — a collection of blood that lies within body tissues or cavities.
Anyone can bleed from a cut or develop a bruise after an injury. The severity of bleeding depends on the impact of an injury.
Repeated bleeding from a skin lesion with minimal provocation can be a sign of skin cancer , most often basal cell carcinoma. Occasional bruises are normal and do not warrant medical attention. Bleeding and bruises are more common in certain individuals, such as:. People with an inherited or acquired coagulation disorder.
