INTERPEDUNCULAR CISTERN
Normal brain anatomy. When there is blood in the brain it can collect in this space.
INTERSTITIAL DISEASE
Imagine that the lungs are like a honeycomb of tissue paper. Interstitial disease is a process (i.e. infection, inflammation, cancer) that affects the tissue paper, but does not involve the air spaces within the honeycomb.
INTERSTITIAL EDEMA
Intermediate stage of pulmonary edema. Fluid accumulates in the “tissue” part of the lungs. Imagine that the lungs are like a honeycomb of tissue paper. In interstitial edema, the tissue paper is soaked with fluid, but the spaces within the honeycomb are still filled with air. In advanced pulmonary edema, the air spaces within the honeycomb starts filling up with fluid. Please look at "pulmonary edema" for a slightly different description that may help you understand this better.
INTERSTITIAL THICKENING
Imagine that the lungs are like a honeycomb of tissue paper. With interstitial thickening, the tissue paper becomes thicker (i.e. when soaked with fluid). This can be detected on a chest x-ray.
INTERTROCHANTERIC
Area between greater trochanter and lesser trochanter of the femur (upper thigh bone).
INTRA-AXIAL
Located inside the brain. Is different than extra-axial that is located outside the brain but inside of the skull.
INTRA-ORBITAL
Located inside the orbit or “eye-socket”.
INTRA-VENTRICULAR
Located inside the ventricle.
INTRAARTICULAR
Within a joint.
INTRACAPSULAR RUPTURE
This is a type of breast implant rupture where the silicone leaks out of the implant bag BUT is contained within the implant capsule. This type of rupture can be very difficult to detect on a mammogram but can be diagnosed with MRI. Please see "capsule" and "extracapsular rupture" for more information.
