A medical or diagnostic technique that does not require the penetration of the skin or body cavities, minimizing the need for surgical incisions.
Techniques such as X-rays, ultrasound, CT scans, and MRI that allow healthcare professionals to visualize internal structures without invasive measures.
A non-invasive imaging technique using high-frequency sound waves to create real-time images of internal organs, tissues, and blood flow.
A non-invasive imaging method that uses electromagnetic radiation to produce images of bones and some soft tissues, valuable for diagnosing fractures and certain conditions.
An advanced imaging technique using magnetic fields and radio waves to generate detailed images of soft tissues, organs, and the brain without exposure to ionizing radiation.
A non-invasive imaging method that combines X-rays and computer processing to create detailed cross-sectional images of the body, helpful for detecting abnormalities and guiding interventions.
A non-invasive test measuring the electrical activity of the heart, aiding in the diagnosis of heart conditions such as arrhythmias and ischemic heart disease.
A portable device for continuous, non-invasive monitoring of heart activity over an extended period, often 24 to 48 hours.
A non-invasive method for monitoring oxygen saturation in the blood, commonly measured using a small device attached to a finger or earlobe.
A specialized ultrasound technique that assesses blood flow in vessels, commonly used to evaluate the circulatory system.
Monitoring blood pressure without the need for invasive procedures, typically using an inflatable cuff and a pressure gauge.
A non-invasive method to identify allergic reactions by applying small amounts of potential allergens to the skin and observing for a reaction.
While often considered invasive, some endoscopic procedures, such as upper gastrointestinal endoscopy, may be considered non-invasive as they involve minimal insertion.
