MRI is a method of obtaining detailed pictures
of internal body structures with the use of magnetic
field and radio frequency pulses.
MRI detects abnormalities with accuracy, especially
those involving the soft tissue. In fact, MRI
may reduce the need for biopsies, exploratory
surgeries, and other high-risk procedures. MRI
is commonly used as a primary diagnostic tool
with no associated risk to the patient, while
providing high-quality clinical evaluations of:
Open
MRI is designed to alleviate anxiety and claustrophobia
that is sometimes associated with the High Field
MRI.
The Open MRI has an open gantry on three sides
and delivers premium image quality, while providing
the highest level of patient comfort. It is often
the optimum choice for children, seniors, large
persons, and claustrophobic patients.
High
Field MRI
The High Field MRI may provide a more accurate
diagnosis for some specific indications, such as
small joint imaging, due to its high level of resolution.
An additional benefit of the High Field MRI is the
shorter exam time, due to the high field strength.
Therefore, it is often the optimal choice for patients
with no history of claustrophobia.
Breast
MRI
The Breast MRI has been approved by the U.S. Food
and Drug Administration (FDA) since 1991 for use
as a supplemental tool, in addition to mammography,
to help diagnose breast cancer. Breast MRI uses
Magnetic Resonance Imaging (MRI) to look exclusively
at the breast. It is a non-invasive procedure that
physicians can use to determine what the inside
of the breast looks like without having to do surgery
or compress the breast, as in a mammogram. Each
exam produces hundreds of images of the breast that
are then read by a radiologist. No radioactivity
is involved, and in most cases, the technique is
believed to have no health hazards.
The procedure for an MRI of the breast involves
the patient lying on her stomach with both breasts
hanging freely into a cushioned recess containing
the breast coil. The entire bed on which she is
lying is advanced into a tube-like machine open
at both ends that resembles a huge donut. Anyone
can have a breast MRI, but mostly patients are women
who already have a cancer diagnosis and plan to
have surgery or chemotherapy followed by surgery,
or those with a suspicious lump or mammogram, who
are also going on to have a biopsy or surgery. Women
may also be candidates if they have dense breasts,
implants, or scar tissue from previous breast surgery,
which may prevent mammography from providing a sufficient
picture of the breast.
For more information or a referral for a Breast
MRI, please contact your primary physician.
PET
Scan
Az-Tech
Radiology is please to offer advanced diagnostic
imaging services with the installation of our new
Philips ALLEGRO PET (Positron Emission Tomography)
scanner at the Casa Grande and Apache Junction locations.
PET is an emerging trend in diagnostic imaging that
allows physicians to make more accurate evaluations
of various cancers and determine the most beneficial
course of action. PET imaging has also been shown
to be an effective tool in the evalutation of certain
cardiac diseases as well as various skin and brain
disorders.
Unlike other diagnostic imaging modalities, PET
shows metabolic activity and can reveal disease
states before structural damage is evident. Currently,
the most common applications of PET in cancer patients
are detectiong recurrent disease early, diagnosing
disease when other tests are inconclusive, staging
the extent of the disease, and monitoring the reponse
to therapy.
Dexa
Scan
What
Is Osteoporosis?
Osteoporosis is a condition which gradually weakens
bones, causing them to become brittle and prone
to fractures. It is estimated that more than 10
million Americans suffer from osteoporosis and another
18 million have low bone density. By age 50, a woman
has more than a 38% chance of developing an osteoporotic
fracture during her lifetime.
Osteoporosis is a serious disease, but is treatable
if detected in the early stages. Most physicians
recommend a DEXA scan at the age of 40 when risk
factors are present. However, if no risk factors
are present, a baseline DEXA at age 50 (or at
menopause) is still suggested.
A DEXA scan, or bone density measurement, will
determine your bone mineral density (BMD) and
compare the result with the BMD of an average
young adult. If osteoporosis is detected, your
physician may suggest specific diet instructions,
exercise, or medication, depending upon the amount
of bone mineral loss.
What Are the Risk Factors?
Women who are postmenopausal are at the highest
risk for osteoporosis. The presence of any one of
the following factors can add to your risk:
- Caucasian or Asian ethnicity
- Thin or small body structure
- Family history of osteoporosis or stress fracture
- Early menopause (before age 45)
- Cigarette smoking
- Inactive lifestyle
- Long-term use of some medications, such as steroids
- Excessive alcohol use
- Low calcium intake
- Thyroid diseases
- Eating disorders
It is possible to have osteoporosis even if you
have no risk factors; therefore, it is important
to discuss having a DEXA scan with your physician.
Is a DEXA Scan Safe?
The radiation exposure is minimal, but you should
not have this exam if you are pregnant. Please alert
your physician and our staff if you might be pregnant.
DEXA is a simple procedure that measures the
bone mineral density in your hip and spine, while
you lie on the table. DEXA scans are quick, safe,
and painless, and the entire exam takes less than
30 minutes.
CT
Scan
What
Is CT?
Computed Tomography (CT or CAT
scan) can look inside your body by creating multiple
cross-sectional images. Imagine a loaf of bread
and examining each slice separately.
The images are created using special Xray equipment
that applies computer processing to synthesize the
images into a cross-sectional view of body tissues
and organs.
Common Uses of CT
CT can be used for cancer detection and can even
determine the size and shape of a tumor, where its
located in the body, and whether the tumor is solid
or hollow. Additionally, CT exams can be used to
guide biopsy needle insertion and for radiation
treatment and planning. In addition to cancer detection,
CT is commonly used for evaluation of post-traumatic
injuries as well as for assessment of patients with
suspected aneurysm or stroke.
How Does CT Work?
You will be asked to lie down on the CT scanners
movable table. The table is passed through a large
donut-shaped ring, as the scanner begins to take
pictures of your body. These are the images that
will be reconstructed by the computer into a cross-sectional
view. In some cases, the use of a contrast material
may be needed to enhance the image. The contrast
material may be orally or intravenously administered,
depending on the particular type of CT study being
performed.
Mammograms
What Is Mammography?
Mammography is a low-dose X ray study of the breast.
It can detect breast cancer in the early stages
of development, while it is small and often before
it can be detected with physical examination. Your
health care provider may order a screening or diagnostic
mammogram depending upon your specific need.
Screening Mammography is for women with no current
breast concerns. The exam consists of two or three
views of each breast while the breast tissue is
compressed. Breast compression is important because
it spreads out the breast tissue and can make the
difference between finding or missing an early breast
cancer. The results of your exam will be mailed
to you and your health care provider.
Diagnostic Mammography is recommended for women
with an abnormal mammogram or a breast- related
problem (such as lump, thickening, a focal point
of pain, nipple retraction, skin dimpling, or
spontaneous nipple discharge). A diagnostic mammogram
is a problem-solving mammogram, and additional
views are frequently required. The exam is tailored
to your specific problem. A radiologist will interpret
your exam and provide you with the results during
your appointment. A copy will also be delivered
to your health care provider.
Ultrasound is a breast imaging study using sound
waves to acquire images of the breast tissue.
Ultrasound is primarily used as an exam to further
evaluate an abnormality detected on a mammogram
or to evaluate an area of palpable concern. Ultrasound
can distinguish between fluid filled cysts and
solid masses.
About Breast Cancer
Eighty percent of women diagnosed with breast cancer
have no family history of breast cancer. Currently
the cause of breast cancer is unknown. With early
detection, most women with breast cancer can be
cured. Early detection is maximized through a combined
approach of regular breast exams and mammography.
Breast self-examination (BSE) is an important
component in the early detection of breast cancer.
BSE should be performed every month. Regular examination
can help you to become familiar with your breast
tissue, making it easier to notice if a change
occurs in your breast. If you have questions about
BSE, please ask our staff for educational material.
In addition to BSE, you should schedule a physical
breast exam with your health care provider every
year.
The American Cancer Society recommends that women
begin annual screening mammography at age 40.
Although no diagnostic tool is 100% effective,
mammography is critical in early detection. Many
breast cancers can be detected by mammography
at least 2 years before a cancer can be detected
by a physician during breast examination.

Ultrasound
Ultrasound
imaging (also called sonography) uses
high-frequency sound waves to create visual images
of the internal body structures. As the sound waves
pass through the body, some of the waves are absorbed
by the bodys tissues, while others are reflected
back. The reflected sound waves are measured and
displayed by a computer, which then creates a real-time
image on a monitor. The sonographer will electronically
store the images, which will be studied and evaluated
by the radiologist.
Common
Uses: Many patients are familiar with the use
of ultrasound during pregnancy. However, it also
offers several other diagnostic applications. Ultrasound
can detect the source of pain or inflammation inside
the body and can reveal infection or tumors. It
is often used for patients with suspected gallstones.
Ultrasound can also evaluate the arteries and veins
for narrowing, blockages, or clots.
Your Ultrasound exam: You will be asked to lie down
on an examination table. The sonographer will apply
a clear gel to the skin over the area that is being
studied. The sonographer passes a small device,
referred to as a transducer, over the skin. The
sound waves that create the ultrasound images are
sent through the transducer. You will be able to
get dressed and leave immediately following the
procedure. Most exams take less than 30 minutes.
