Radial EBUS bronchoscopy
For this biopsy, a flexible bronchoscope is fitted with an ultrasound device and
guided to the cancer site. An ultrasound uses high-frequency sound waves to
make pictures of the insides of the body. Your doctor will move the device back
and forth to see a 360-degree view of the area on a computer. The ultrasound
device will then be removed so that the sampling tool can be inserted.
Navigational bronchoscopy
The airways of the lungs get smaller as they extend toward the sides of the
body. Flexible bronchoscopes are often too large to travel through these small
airways. A navigational bronchoscopy uses a flexible bronchoscope that is fitted
with a second open channel that is thinner and longer. For this biopsy, your
doctor will first plan how to reach the cancer site using a CT image. Your doctor
will then guide the bronchoscope to the site with a sensor that will be inserted
through an open channel. When the site is in reach, the sensor will be removed
and the sampling tool will be inserted.
TTNA
This biopsy is also called a percutaneous needle biopsy. It uses a very thin
needle that is inserted through the chest wall to get a tissue sample. It is
recommended that an imaging test be used to insert the needle to the right
spot. Before inserting the needle, your skin will be cleaned and numbed with
local anesthesia. Next, a small cut will be made into your skin. The needle will
be inserted through the cut and into the nodule. During the biopsy, you may be
asked to stay still and hold your breath at times. After the biopsy, the cut will be
bandaged and you will be given a chest x-ray to check the results. After TTNA,
you may feel sore and have some redness at the needle site.
