Computed Tomography01:10

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Summary
This summary is machine-generated.

Fluoroscopic procedural computed tomography (FPCT) navigation offers CT-like imaging quality for guiding percutaneous procedures. This technology enabled successful, complication-free ventricular drain placement in a hydrocephalus patient at the bedside.

Area of Science:

  • Medical imaging
  • Neurosurgery
  • Medical device technology

Background:

  • Conventional CT imaging requires patient transfer, posing risks for critically ill patients.
  • Fluoroscopic navigation systems offer real-time imaging but may lack detailed anatomical visualization.
  • Percutaneous procedures demand precise instrument guidance for optimal outcomes.

Observation:

  • Contemporary fluoroscopic units equipped with FPCT and navigation software provide imaging quality comparable to conventional CT.
  • The system allows for live instrument visualization during percutaneous procedures.
  • Re-imaging is possible without the need for patient transfer.

Findings:

  • FPCT navigation was successfully employed in a bedside technique for ventricular drain placement in a 62-year-old female patient with subarachnoid-related hydrocephalus.
  • Ventriculostomy catheter placement was technically successful.
  • The procedure was completed without any complications, with the catheter accurately positioned at the foramen of Monro.

Implications:

  • FPCT navigation represents a significant advancement in image-guided percutaneous interventions, particularly at the bedside.
  • This technology enhances safety and efficiency by eliminating patient transfer and providing real-time visualization.
  • FPCT navigation holds potential for broader application in neurosurgical and other percutaneous procedures, improving patient care.
