Photostress recovery time measurement procedure is known as photostress test. Normal recovery time is about 15–30 seconds. [1] The photostress test is a simple, easy and quick clinical technique that can differentiate between retinal and postretinal (e.g.optic nerve) disease. [2]
Davis's law is used in anatomy and physiology to describe how soft tissue models along imposed demands. It is similar to Wolff's law, which applies to osseous tissue. It is a physiological principle stating that soft tissue heal according to the manner in which they are mechanically stressed. [1]
Soft tissue connects and surrounds or supports internal organs and bones, and includes muscle, tendons, ligaments, fat, fibrous tissue, lymph and blood vessels, fasciae, and synovial membranes. [ 1 ] [ 2 ] Soft tissue is tissue in the body that is not hardened by the processes of ossification or calcification such as bones and teeth .
Stress hives look similar to other types of skin rashes, but have a different cause. Here, find stress hive pictures and how to get rid of stress hives.
A crush artifact is an artificial elongation and distortion seen in histopathology and cytopathology studies, presumably because of iatrogenic compression of tissues. Distortion can be caused by the slightest compression of tissue and can provide difficulties in diagnosis. [2] [3] It may cause chromatin to be squeezed out of nuclei. [4]
It does so by creating a 'push' inside the tissue using the acoustic radiation force from a focused ultrasound beam. The amount the tissue along the axis of the beam is pushed down is reflective of tissue stiffness; softer tissue is more easily pushed than stiffer tissue. ARFI shows a qualitative stiffness value along the axis of the pushing beam.
Fig. 10. Surface coil artifact: high signal at anterior thoracic wall adjacent to surface coil. [1] Absence of signal from tissues of a particular T1 value is a consequence of magnitude sensitive reconstruction in inversion recovery imaging. When the chosen T1 equals 69% of the T1 value of a particular tissue, a bounce point artifact occurs. [1]
A soft tissue injury is the damage of muscles, ligaments and tendons throughout the body. Common soft tissue injuries usually occur from a sprain, strain, a one-off blow resulting in a contusion or overuse of a particular part of the body. Soft tissue injuries can result in pain, swelling, bruising and loss of function. [1]
