Which imaging technique is commonly abbreviated as CT?

• A. Computerised Tomography (CT)
• B. Magnetic Resonance Imaging (MRI)
• C. Positron Emission Tomography (PET)
• D. Electrical Stimulation of the Brain (ESB)

Answer: (A)

The imaging technique commonly abbreviated as CT is computerized tomography. It uses X-ray beams that rotate around the body, and a computer reconstructs the data into cross-sectional images. This makes it fast and widely available, which is especially useful for quickly assessing brain injuries or strokes in emergencies. CT is good for seeing bone and acute bleeding, but it provides less soft-tissue detail than MRI and involves exposure to ionizing radiation. The other options refer to different approaches: MRI uses magnetic fields and radio waves to create detailed soft-tissue images without radiation; PET maps metabolic activity with a radioactive tracer; and electrical stimulation of the brain is a neuromodulation method, not an imaging technique.
