Computed tomography guidance

What are the principles of computed tomography?
CT uses ionizing radiation, or x-rays, coupled with an electronic detector array to record a pattern of densities and create an image of a “slice” or “cut” of tissue..
What is a CT guide?
During a CT-guided biopsy, the physician will use the CT scan as a guide as he or she inserts the needle into the right location to remove a sample of the tumor.
In addition to detecting cancer, CT scans have many other uses._{Sep 21, 2023}.
What is CT guidance for stereotactic localization?
In this procedure, the provider uses computed tomography guidance to locate small targets inside the body using a three–dimensional coordinate system..
What is CT guided intervention?
Computed tomography (CT)-guided interventional radiology uses minimally invasive techniques to perform diagnostic and therapeutic medical procedures.
CT commonly is used for interventional image guidance because it is readily available and can be performed with a wide range of equipment..
What is CT protocol?
A CT protocol is a set of parameters that specify a specific exam and contrast delivery requirements..
Why it is necessary to select appropriate protocol before CT scan procedure?
Physicians influence patient radiation dosethrough monitoring protocols and targeting body-part- and disease-specific protocols that can minimize dose.
The goal in selecting protocols is not necessary to create the highest technical quality image but to generate a diagnostic image using the lowest dose possible..
A radiologist (a physician who specializes in reading and interpreting CT scans and other radiologic exams) will review your scan and prepare a report that explains the findings.
In an emergency setting, like a hospital or emergency room, healthcare providers often receive results within an hour.
CT uses ionizing radiation, or x-rays, coupled with an electronic detector array to record a pattern of densities and create an image of a “slice” or “cut” of tissue.
The x-ray beam rotates around the object within the scanner such that multiple x-ray projections pass through the object (Fig 1).

May 1, 2023When used appropriately, the benefits of a CT scan far exceed the risks. CT scans can provide detailed information to diagnose, plan treatment

There are many advantages to CT guidance for certain spinal interventional pain procedures, mainly due to increased needle tip positioning accuracy. CT guidance provides greater anatomical detail that facilitates accurate needle trajectory planning, monitoring and final placement.
