What is a 3D mammography?
Mammography is the gold standard in breast cancer detection. 3D mammography is a cutting-edge
technique that creates “slices” of images of the breast tissue
to allow medical providers to view three-dimensional images.
Why is 3D mammography needed? For women of a certain age, doctors recommend
an annual screening mammogram. Women also undergo mammograms if their
doctors detect abnormal changes of the breasts that may indicate cancer.
Men may sometimes be referred for 3D mammography, as it is possible for
them to develop breast cancer. With digital 3D mammography, providers
can detect abnormalities that may have escaped detection with 2D mammograms.
Which equipment is used? Our imaging facility was the first to offer digital
mammography in San Antonio. We use the Hologic Selenia Dimensions 3D mammography
system, which is a sophisticated system that incorporates the latest tomographic
imaging capabilities. With this equipment, our patients can also undergo
What is an MRI?
Magnetic resonance imaging is a noninvasive and usually painless medical imaging test that guides
physicians in making a diagnosis and planning a patient’s treatment.
At Concord Imaging, our digital technology makes it possible for physicians
to clearly view precise images on a computer.
Why is an MRI needed? Physicians refer patients to Concord Imaging for
MRIs for a variety of reasons. These medical images can reveal conditions
and diseases of the brain, pelvic region, chest, abdomen, blood vessels,
lymph nodes, and heart. An MRI can help physicians diagnose inflammatory
bowel diseases (IBDs), tumors, vascular disease, and bone abnormalities.
Patients may also undergo an MRI after the diagnosis to assess how well
their treatment is working.
Which equipment is used? Patients lie on a moveable table, which slides
into the center of a large, circular magnet. The technologist goes into
an adjacent room that looks out into the exam room. A sound system allows
the patient and technologist to communicate during the exam. The MRI equipment
captures images through the use of radio waves and a powerful magnetic field.
What does an MRI reveal? MRI scans can depict the bones, organs, and soft
tissues throughout the body. It may reveal evidence of diseases or structural
abnormalities. In some cases, patients receive an injection of contrast
material prior to the exam, which allows for clearer, more precise images.
What is a CT scan? A
computed tomography scan is a noninvasive medical test that uses special X-ray technology
to produce cross-sectional images of the internal structures of the body.
Sometimes, contrast dye is used for this exam. Although CT scans use X-ray
technology, they produce images that are far more detailed and precise
than standard X-rays.
Why is a CT scan needed? CT scans are often the test of choice for quickly
diagnosing the cause of a patient’s pain, particularly when symptoms
are localized to the chest, abdomen, or pelvic region. CT scans may be
used to look for internal trauma, digestive disorders, skeletal problems,
and vascular diseases and conditions, such as pulmonary embolism. CT scans
are frequently used to detect multiple forms of cancer. The detailed images
allow doctors to clearly detect, measure, and evaluate tumors.
Which equipment is used? Patients are positioned on a moveable table that
slides into a short tunnel. The gantry is a circular frame that rotates
around the patient. The X-ray tube and X-ray detectors are mounted to
the gantry so that they revolve around the body. Each time the equipment
makes a full revolution around the patient, it produces another “slice”
or image of the internal structures.
What does a CT scan reveal? By allowing doctors to examine the internal
structures slice by slice, CT scans reveal highly detailed cross-sectional
images of the organs, bones, blood vessels, and soft tissues.
What is a PET scan?
Positron emission tomography scans use radiotracers to evaluate cellular changes in the body. Radiotracers
are small amounts of radioactive materials. By revealing information about
minute metabolic changes, PET scans allow physicians to detect diseases
quite early in their onset.
Why is a PET scan needed? Most often, PET scans are used to detect cancer
and Alzheimer’s disease. Active tumors absorb radiotracers more
quickly than other tissues. This lets physicians detect small lesions
and tumors. A PET scan can determine whether cancer has spread, how well
cancer treatments are working, and whether cancer has recurred. PET scans
also show changes in the brain’s chemistry, which allows for the
early diagnosis of Alzheimer’s disease. At Concord Imaging, we’re
pleased to offer Amyvid, a recently approved agent that allows for the
detection of beta amyloid plaque. After this injection, patients can undergo
a PET scan to look for plaque deposits, which can indicate early Alzheimer’s disease.
Which equipment is used? The PET scanner is a large machine with a round
hole in the center, through which a moveable exam table is inserted. Detectors
are arranged around this hole. These detectors record the energy emitted
by the radiotracer. Although a PET scan may be performed alone, it’s
more effective when combined with a CT scan. A PET/CT scan can be performed
simultaneously. Regarding cancer patients, the PET scan can detect the
presence of tumors and the CT scan can precisely pinpoint their location.
What does a PET scan reveal? Unlike most medical scans, which reveal fixed
or static images, a PET scan is a measurement of bodily functions. With
PET scans, doctors can evaluate oxygen use, blood flow, and glucose metabolism
to assess how well the body is functioning.
What is an ultrasound? An
ultrasound uses high-frequency sound waves to generate images of the body. The ultrasound
images are viewable in real time, which means that they reveal internal
movements, including blood flow.
Why is an ultrasound needed? Ultrasound imaging is commonly associated
with prenatal testing. Since it does not use X-rays, it’s safe for
pregnant women. Ultrasound is also used for guiding needle biopsies, diagnosing
the causes of pain, and checking for blood clots.
Which equipment is used? Concord Imaging is pleased to feature the GE Ultramark
9 system. This ultrasound machine produces clear, easily interpreted images
for maximum accuracy. The ultrasound machine generates images from information
obtained via the transducer. The transducer is a hand-held device that
makes contact with the skin.
What is nuclear medicine?
Nuclear medicine involves introducing small amounts of radioactive substances to the body,
usually via injection or by mouth. The radiotracer circulates in the body
and emits gamma rays. Medical imaging equipment detects these gamma rays
and uses this information to create images.
Why is nuclear medicine needed? Nuclear medicine reveals the structure
and function of tissues and systems in the body. These tests can be used
to diagnose cardiovascular conditions, evaluate the lungs for respiratory
problems, and check the bones for fractures or tumors. Nuclear medicine
scans are also used to assess the brain, bowel, and spine.
What is a bone densitometry scan?
Bone densitometry or dual-energy X-ray absorptiometry (DEXA) uses X-ray technology to generate
images of the bones. Specifically, it measures a patient’s bone
mineral density (BMD). This allows physicians to evaluate the strength
of the bones and the patient’s risk of fractures.
What is bone densitometry used for? Bone density scans are most often recommended
for patients at risk of osteoporosis, which is a condition in which reduced
bone mass causes the bones to become more fragile and susceptible to fractures.
A radiologist may scan the whole body or just the lower spine and hips.
