Focal cystic changes refer to localized areas within a tissue or organ that exhibit cyst-like formations, which are fluid-filled sacs. These changes can occur in various organs, such as the liver, kidneys, or breast, and may be benign or indicative of underlying pathology. They are often identified through imaging studies, such as ultrasound or CT scans, and may require further evaluation to determine their significance. The clinical implications depend on the specific context and associated symptoms.

The eye has variable focal length, its lense varies with thickness in order to focus to distant or nearby objects. Focal distance is constant, from lense to retina.
The focal length of a lens is the distance from the center of the lens to the point at which it focuses light rays. The bigger the focal length, the more powerful the lens. ChaCha!
Cystic changes in lung aspirates refer to the presence of cyst-like structures or spaces within lung tissue, often observed in imaging or pathological examinations. These changes can result from various conditions such as infections, inflammation, or neoplastic processes, leading to the formation of air-filled or fluid-filled cavities. In lung aspirates, identifying cystic changes can help differentiate between benign and malignant processes and guide further diagnostic evaluation and management.
No, the focal length of a mirror does not change when the object distance changes. The focal length of a mirror is a fixed property of the mirror itself. Changing the object distance will affect the position and size of the image formed by the mirror, but not the focal length.
I don't think so. The focal length would remain the same. It mainly depends on the radius of curvature of the mirror.
no. It sometimes changes but not all the time
A cystic foci, or cystic focus, is when an ultrasound identifies a finding that is cystic-like. It mean there's a tiny collection of fluid wherever the cystic focus was found.
As a convex lens becomes flatter, its focal length increases. This is because a flatter lens bends light rays less, causing them to converge further away before focusing, resulting in a longer focal length.
I'm pretty sure they just provide a glass median to change your eye's focal point. Since our eyes can get strained over time, which changes our focal point to become nearsighted or farsighted, glasses vary in thickness to compensate for the problematic focal point.
Subchondral cystic changes are fluid-filled cavities that form in the bone just underneath the cartilage in a joint. They can be seen on imaging studies like MRI and may be related to conditions such as osteoarthritis or bone trauma. These cysts can cause pain, stiffness, and joint instability.
