Trauma......was there a fall or sports injury?.....If so possible meniscus tear......Trauma to a knee can cause both...
fluid inside the knee joint
Im pretty sure it just means a very small amount of effusion.
intermediate joint
There are many e.g. over 30 small joint surfaces in the wrist and hand. It is hard to say. Answer The smallest bony joint in the skeleton is found within the head. It is that between the two ossicles incus and stapes.
A "Bursa" is plural for "Bursae " which is a fluid-filled sac lined by synovial membrane with an inner capillary layer of slimy fluid (similar in consistency to that of a raw egg white). It provides a cushion between bones and tendons and/or muscles around a joint. This helps to reduce friction between the bones and allows free movement. Bursae are filled with synovial fluid and are found around most major joints of the body. There are 160 bursae in a human body. Without the bursa, movement would be painful. Bursitis is the inflammation of the bursa. They can become inflamed from injury, infection (rare in the shoulder), or due to an underlying rheumatic condition. Examples of bursitis include injury as subtle as lifting a bag of groceries into the car to inflame the shoulder bursa, infection of the bursa in front of the knee from a knee scraping on asphalt, and inflammation of the elbow bursa from gout crystals.
fluid inside the knee joint
A small amount of fluid build up at the joint, possilby a sign of slight arthritis, mild gout or a moderate physical trauma ( for example a fall onto the knee).
Im pretty sure it just means a very small amount of effusion.
The movement of gas through a small hole into an area of lower pressure is diffusion.
effusion
EFFUSION
effusion is the process where individual molecules flow through a hole without collisions between molecules. effusion is the process where the gas molecules are passed through a small opening to an evacuated chamber
The contrast needs to be lowered. This allows for more "gray" to develop in the radiograph, which is what the effusion will show up as. With high contrast radiographs, abdominal fat, effusion fluid and the abdominal viscera tend to blend together.
intermediate joint
A process related to diffusion is effusion, the process by which a gas escapes from a container into a vacuum through a small hole. The rate of effusion is also related to root mean square velocity-heavier molecules effuse more slowly than lighter ones. The rate of effusion-the amount of gas that effused in a given time- is inversely proportional to the square root of the molar mass of the gas.
kVp should be increased by 15%
It is a medium sized joint.
