A **Scoliosis series** is a set of spine X-rays taken in standardized positions. It is commonly used to **evaluate and measure spinal curvature** and overall alignment. Spine specialists use it in clinics and hospitals to guide monitoring, bracing, and surgical planning. It is most often performed for children, teens, and adults with suspected or known scoliosis.

INR stands for *International Normalized Ratio*. It is a standardized number calculated from a blood clotting test called the prothrombin time (PT). INR is most commonly used to monitor the effect of warfarin (a vitamin K–antagonist blood thinner). It also helps clinicians understand clotting changes in certain illnesses, including liver disease and major bleeding.

EOS imaging is a type of low-dose X-ray system that captures full-body or full-spine images while a person is standing. It is commonly used in spine and orthopedic clinics to evaluate alignment in a weight-bearing position. It can produce both 2D images and, in some cases, 3D reconstructions of bones and joints. It is often discussed in the context of scoliosis, spinal balance, and lower-limb alignment.

eGFR stands for *estimated glomerular filtration rate*. It is a lab-reported estimate of how well the kidneys filter blood. It is usually calculated from a blood test (often creatinine) plus basic patient factors. It is widely used in primary care, nephrology, cardiology, and hospital medicine.

Flexion-extension radiographs are X-ray images taken while a person bends forward (flexion) and backward (extension). They are used to see how the spine moves under controlled, real-life positions. They are commonly ordered for the neck (cervical spine) and lower back (lumbar spine). They help clinicians evaluate possible abnormal motion, also called spinal instability.

Creatinine is a natural waste product made by muscles during normal energy use. It is cleared from the blood by the kidneys and removed in urine. Clinicians measure Creatinine to understand kidney filtration and overall kidney function. It is commonly used in cardiovascular care because many heart tests and treatments depend on kidney performance.

Oblique view is an imaging angle that looks at the body from the side and front at the same time. It is most commonly used in X-rays, CT scans, MRI scans, and fluoroscopy to better show certain spine structures. In spine care, Oblique view can make openings for nerves and small bony joints easier to see. It is a descriptive term for the image orientation, not a treatment.

Sodium is a mineral and an electrolyte that carries an electrical charge in body fluids. It helps regulate fluid balance, blood pressure, and nerve and muscle function, including the heart. Sodium is commonly found in table salt and many packaged foods. It is also measured in blood tests and can be given as part of intravenous (IV) fluids or medications.

Lateral view is a way of looking at the body from the side. In spine care, Lateral view most often refers to a side-angle image on X-ray, fluoroscopy, CT, or MRI. It helps clinicians assess alignment, bone relationships, and certain patterns of injury or wear. It is commonly used in clinics, emergency settings, and preoperative or postoperative evaluations.

Magnesium is a mineral and electrolyte that the body needs to function normally. It helps regulate electrical activity in nerves and muscles, including the heart. It is found in foods and is also available in supplements and prescription formulations. In cardiovascular care, it is commonly discussed in lab results and used to treat specific rhythm and electrolyte problems.
