What is CT guided biopsy?

CT guided biopsy is performed to give a detailed picture of your body tissue and organs which help take a small tissue through a needle as a sample for testing. This helps to give a a proper diagnosis and evaluate the treatment. CT scan is the safest and fastest  way to let guide the needle inside without doing an open surgery. 

 

How can I prepare for the scan?

  • When you schedule your integrated CT guided biopsy, you will receive detailed instructions on how to prepare. For example, you may be told to drink nothing but water beginning at midnight the night before your appointment and instructed to not eat or drink anything for at least six hours before your biopsy begins.  
  • Women should tell their doctors if there is any chance they may be pregnant because a CT scan could put the baby at risk. If in doubt, make sure to take a pregnancy test before performing the scan
  • CT scans cannot be done in lactating women. If it is absolutely necessary, you should pump and store your breast milk beforehand. Until the radiotracer is completely gone from your system, you cannot feed your baby the breast milk and need to pump your breast milk and discard it till the traces are gone .
  • Do not take aspirin, ibuprofen (Advil, Genpril, Haltran, IBU, Menadol, Midol, Motrin), or vitamin E for 3-7 days prior to the biopsy.
  • You may also want to check your insurance plan to find out what it covers and whether you will have any out-of-pocket costs associated with the scan.
  • It is recommended that you come with one relative to help you during the course of the scan.
  • Wear comfortable clothing and avoid jewellery or any other metal on the body.

How is the CT guided biopsy done?

The process you will follow when you go for a CT guided biopsy is as follows:
  • If a contrast dye is used, it will be given to you by mouth (oral contrast) or injected into a vein in your arm (intravenous). 
  • Before the test, you will need to change into a hospital gown and remove any jewellery or metal objects that you are wearing.
  • You will be taken into the scanning room. If you have been given oral contrast, you will need to wait for about 45 to 60 minutes before being taken to the scanning room. This waiting time is needed for the contrast to move through your digestive tract.
  • The CT scanning machine is shaped like a doughnut. You will be made to lie on the imaging bed. After you have been positioned properly, the helper leaves the scanning room. The technician present in the control room can see you through a glass window. If there is no visibility to the scanning room from the control room patients are fully monitored through closed circuit television screen. The technician communicates with you through an intercom.
  • The bed is moved slowly through the scanner. The X-ray machine will rotate around you and produce several images of thin slices of your body. You will need to lie very still while the images are being captured. 
  • When needed, the technician will instruct you to hold your breath for several seconds so that you remain still. The scanning takes about 15-20 minutes on the scanning table.
  • After which you will be kept under observation to monitor any allergic reaction 
  • Sometimes, a delayed scan/re-scan may be required at times. 
  • The images created during the scan will be reviewed by the radiologist.

Can I walk in for a CT guided biopsy without prior appointment?

  • A prior appointment is preferred since the radiotracer material has to be ordered beforehand as per the number of patients scheduled. 
  • Also you may be told to drink nothing but water beginning at midnight the night before your appointment and instructed to not eat or drink anything for at least six hours before your biopsy begins.
