When the Doctor Requests Abdominal Imaging
Abdominal imaging allows our
specialized physicians (radiologists) to look inside the body. In combination
with a doctor’s findings, an accurate diagnosis can be made.
UT
Southwestern’s Abdominal Imaging team provides comprehensive imaging and
diagnostic services for disorders in the abdomen and pelvis area. These include
diseases of the esophagus, stomach, small and large bowel, liver, kidneys,
pancreas, prostate, uterus, ovaries, and other organs.
We see patients
with both acute pain, such as that due to appendicitis, and chronic pain, such
as that associated with cancers.
How Abdominal Imaging Works
Some imaging
techniques, such as CT and fluoroscopy, expose patients to a small amount of
radiation. This amount is always kept “as low as reasonably achievable,” a
safety principle known as ALARA. Compared with other radiology facilities, our
radiation doses are in the bottom 25 percent of the national average. Other technologies,
such as MRI and ultrasound, do not use any radiation.
Abdominal
imaging is also used to guide percutaneous biopsies (tissue samples removed using
a needle inserted through the skin) and other interventions, such as draining
fluids from abscesses within the abdomen and pelvis.
Specialized Abdominal Imaging Services
Our expert
team offers specialized tests that often cannot be performed in community
hospitals or imaging centers. In fact, we are one of a few sites in the country
that offers spectral CT. Our abdominal imaging services include:
- CT
angiography (CTA): Integrates X-rays with
computer processing to create cross-sectional images of the bones and soft
tissues
- CT
enterography: Uses X-rays in a specialized study for abdominal pain,
especially in patients with Crohn’s disease and ulcerative colitis
- CT
virtual colonoscopy: Uses CT
imaging to examine the large intestine and can replace standard colonoscopy
in some cases
- Fluoroscopy:
Can be combined with a CT scan to plan surgery for complications of
bariatric surgery and gastric bands
- Sonohysterography:
Uses ultrasound with
saline to visualize the uterus
- 3-D
and 4-D obstetric sonograms:
Uses additional processing with ultrasound technology to produce images
with depth (3-D) and moving images with depth (4-D)
- Contrast-enhanced
ultrasound (CEUS): Uses microbubble injections to identify liver lesions
and guide biopsy
- Spectral
CT: Provides greater accuracy than standard CT scans to identify tumors
Multidisciplinary Conferences
At UT Southwestern, every patient’s
care is thoroughly discussed with members of the medical team to ensure the best
possible medical plan.
Determinations are also made for
eligibility to participate in clinical trials. Virtually every clinical trial
requires CT or MR imaging. Having imaging performed at a UT Southwestern
facility allows the patient’s doctor to quickly view images in the patient’s
electronic medical record.
