Image-guided surgery
Image-guided surgery (pronunciation: /ˈɪmɪdʒ ˈɡʌɪdɪd ˈsɜːrdʒəri/), also known as Computer-assisted surgery, is a surgical procedure that utilizes preoperative or intraoperative images to guide the surgeon's movements during the operation.
Etymology
The term "Image-guided surgery" is derived from the English words "image" (from Latin "imago" meaning likeness or picture), "guide" (from Old French "guider" meaning to lead or direct), and "surgery" (from Greek "cheirourgia" meaning hand work).
Procedure
In an image-guided surgery, images are taken using various imaging techniques such as Computed Tomography (CT), Magnetic Resonance Imaging (MRI), or Ultrasound. These images are then used to create a 3D model of the patient's anatomy, which is used to guide the surgeon during the operation. This allows for more precise surgical interventions and can reduce the risk of damage to healthy tissues.
Applications
Image-guided surgery is used in various medical fields including Neurosurgery, Orthopedic surgery, ENT surgery, and Interventional radiology. It is particularly useful in surgeries where precision is crucial, such as brain tumor removal or spinal surgery.
Benefits and Risks
The main benefit of image-guided surgery is its potential to increase the precision and safety of surgical procedures. However, like all surgical procedures, it carries risks such as infection, bleeding, and reactions to anesthesia. The accuracy of the procedure also heavily depends on the quality of the imaging used.
