(2016)This video demonstrates near-infrared fluorescent (NIRF) imaging to visualize thrombi in excised brain tissue labeled with a fibrin-specific probe. Near-infrared light excites the probe, causing the thrombus to fluoresce, enabling high-contrast thrombi visualization in the major cerebral artery and small cortical blood vessels.

There is a need for a non-invasive assessment of stress. This paper describes a simple protocol using thermal imaging to detect a significant response in eye-region temperature in wild blue tits to a mild acute stressor.
FAQs
The camera detects differences in long-wave infrared energy emitted from the skin and represents them as contrasting colors in a thermogram. These spatial temperature patterns can reveal regional changes rather than a single overall temperature value. Their clinical significance depends on how altered heat distribution relates to blood flow, inflammation, or heat transfer within the observed area.
Blood-flow changes can alter how heat reaches the skin, while inflammation may produce localized temperature differences. Heat transfer also affects the surface pattern, so the image reflects several physiological influences rather than one specific cause. For that reason, a thermogram can support assessment of an abnormal region but does not independently identify the underlying condition.
Because the technique does not use ionizing radiation and requires no direct contact, it can provide a noninvasive way to observe surface temperature patterns. This characteristic allows it to complement clinical examination and established diagnostic tests. The resulting image should therefore be treated as supportive physiological information, not as a replacement for methods used to establish a diagnosis.
A thermal camera observes the body's surface without touching it and detects the long-wave infrared energy emitted from that surface. The system converts differences in detected radiation into a color-coded thermogram for review. Clinicians or researchers then relate visible temperature patterns to the relevant physiological question and interpret them alongside examination findings or other tests.
Medical applications include observing vascular function, evaluating musculoskeletal conditions, monitoring wound healing, and examining responses to treatment. In each setting, the image contributes information about changing surface temperature patterns that may reflect altered physiology. Its value is greatest as a complementary observation that helps track or assess a process together with established clinical methods.
Repeated observation of surface temperature patterns can provide information about physiological changes associated with wound healing or a response to treatment. The method offers a contact-free view of these changes, which may help researchers or clinicians compare patterns over an assessment period. Interpretation still requires clinical context because temperature variation can reflect multiple processes, including blood flow and inflammation.
