Innovative Diagnostic Techniques
A biopsy is a minimally
invasive method of sampling tissue to determine if it is benign, malignant, or
infectious. An image-guided biopsy uses imaging technology that enables us to safely
insert needles into hard-to-reach places in the body, such as the lungs,
kidneys, liver, lymph nodes, and the bones.
UT Southwestern’s
Comprehensive Noninvasive Vascular Imaging Laboratory uses minimally invasive diagnostic
techniques, which offer fewer risks and shorter recovery times for our patients.
In addition to image-guided biopsy, we also offer noninvasive vascular imaging and venous sampling.
Our team uses computed tomography (CT), real-time X-ray
(fluoroscopy), ultrasound,
and sometimes a combination of these imaging techniques to conduct image-guided
biopsies.
Our team of interventional radiologists and physician assistants coordinates each patient’s
complete care – from imaging evaluation to post-procedure follow-up –
maintaining a high level of communication with the patient and his or her physician
throughout the process. In addition, we coordinate closely with experts from
across the UT Southwestern community.
Conditions
We typically use biopsies
to diagnose lymphoma,
kidney cancer, liver cancer, lung cancer, and other soft tissue cancer. A biopsy might also be needed to
diagnose a variety of other conditions, such as kidney, liver, interstitial
lung, or infectious diseases.
Results from these
biopsies are used by our world-class oncologists, infectious disease
specialists, rheumatologists, kidney and liver specialists, and surgeons to
make important treatment decisions.
Preparing for Image-Guided Biopsy
Biopsies are performed
with conscious sedation, a process in which the patient is given medication to
feel sleepy but is not unconscious. Conscious sedation requires that patients
not eat for eight hours before the procedure. Most medications can be taken the
morning of the procedure except those that affect blood clotting, such as aspirin,
Plavix, Lovenox, or Coumadin.
Patients who are taking
one of these medications might need to stop taking it or be switched to another
medicine for a few days before the procedure. Medication management will be
coordinated by our team, if necessary.
Most biopsies are
performed on an outpatient basis. However, depending on what organ is being
biopsied, there might be an observation period of up to four hours following
the procedure.
