3D Dorsal Spine

CT stands for Computed Tomography. It is a computerised X-ray system used to produce images of various parts of the body.     In a conventional x-ray, structures are superimposed on top of one another, making it difficult to get a clear picture. CT scan takes a picture of the body in a single cross-section, giving an unobstructed view of every organ, bone and soft-tissue. CT uses pencil-point x-ray beams from a rotating doughnut surrounding the patient's body. Detectors pick up the signals which vary in strength after they pass through human tissue. The detectors then send this information to a computer, which creates a picture of a single slice of the human body. 
Preparation : As with all nerve conduction studies, the body part tested should be clean, free of lotions and conductive substances, with jewelry removed. It is best to advise patients to refrain from taking acetylcholinesterase inhibitors (e.g., Pyridostigmine Mestinon) for 6–8 hours before the study, unless medically contraindicated
