Magnetic
Resonance Imaging / Open MRI |
|
Magnetic Resonance Imaging is a diagnostic
technique that provides high quality
cross-sectional images of organs and
structures within the body without X-Rays
or Radiation.
There are no known side effects and
no discomfort caused by the procedure.
Most examinations are completed in approximately
30 minutes.
Today’s
open MRI equipments are better than
ever. The open equipment provides more
comfortable, non-confining experience.
You relax while the equipment at work.
With the state of the art equipments,
image quality is as clear and sharp
as conventional closed MRIs.

Computerized
Axial Tomography / CT |
|
Computed tomography (CT), originally
known as computed axial tomography (CAT
or CT scan) is a medical imaging method
employing tomography where digital geometry
processing is used to generate a three-dimensional
image of the internals of an object
from a large series of two-dimensional
X-ray images taken around a single axis
of rotation. Computers are then used
to process the information gathered
to create cross-sectional images that
appear as “slices” of the
body and organs and body tissues.
CT
imaging is particularly useful because
it can demonstrate several types of
tissue – lung, bone, soft tissues
and blood vessels – with great
clarity.
It is the global standard in the diagnosis
of a large number of different disease
entities. Some of the major uses being
Cranial CT, Chest CT, Cardiac CT, Abdominal
and pelvic CT to name a few.

Mammography
(FDA & MQSA Certified) |
|
It is a specific type of imaging that
uses low-dose x-ray system and high-contrast,
high-resolution film for examination
of human breasts. It is used to look
for different types of tumors and cysts.
Mammography has been proven to reduce
mortality from breast cancer. Successful
treatment of breast cancer depends on
early diagnosis. Mammography plays a
central part in early detection of breast
cancers. Mammography can show changes
in the breast up to two years before
a patient or physician can feel them.

Ultrasound
/ Color Doppler |
|
Ultrasound imaging, also known as ultrasound
scanning or sonography, is a method
of obtaining images from inside the
human body through the use of high frequency
sound waves. The sound waves' echoes
are recorded and displayed as a real-time,
visual image. No ionizing radiation
is involved in ultrasound imaging.

X-Ray
& Fluoroscopy |
|
Radiography, commonly known as X-ray,
refers to the use of standard X-rays
to identify healthy or abnormal conditions
within the body. Common X-rays, tomography
and fluoroscopy are all very safe diagnostic
exams because they use a low dose of
radiation.
Conventional radiography (x-ray) is
a simple and painless procedure that
allows the radiologist to analyze the
bony and soft tissue anatomy for diagnosis.
The average x-ray takes 10 - 20 minutes.
Fluoroscopy is an enhanced x-ray that
produces its moving image on a television-like
monitor. It is especially useful in
diagnosing problems of the digestive
tract, kidneys and gallbladder. C-arm
Fluoroscopy is also used in pain management
procedures and radiological intervention.
Sometimes a contrast agent is used to
guide the procedure. The exam typically
takes between 30 and 40 minutes.

Bone
Densitometry |
|
Bone
densitometry is a noninvasive technology
that is used to measure bone mass. Bone
mass, simply put, is the weight of the
skeleton, overall or in specific regions.
Bone mineral density, or BMD, reveals
a risk factor for fractures. BMD is
usually expressed as the amount of mineralized
tissue in the area scanned (g/cm2);
with some technologies it is expressed
as the amount per volume of bone (g/cm3).
A bone density more than 2.5 standard
deviations below the young adult reference
population indicates osteoporosis, a
disease occurring most often (but not
exclusively) among women after the menopause
in which the bones become very porous,
break easily, and heal slowly.

Dual-energy
x-ray absorptiometry (DEXA) |
|
DEXA,
the gold standard in densitometry, uses
one of two methods to create a dual-energy
spectrum from an x-ray source. One method
involves alternating pulses of low and
high kV that are applied to the x-ray
tube. The low- and high-energy spectra
are then measured separately. The other
method applies a constant potential
to the x-ray source while using a K-edge
filter to separate the energy spectrum
into two narrow energy bands. An energy-discriminating
detector with a dual-channel analyzer
counts the resultant photons. The use
of two energies allows bone mineral
to be assessed independently of soft-tissue
inhomogeneities. Bone mineral content
(BMC) and bone mineral density (BMD)
are calculated in g/cm and g/cm2, respectively.
??DEXA scanners use either a pencil
beam coupled to a single detector (first
generation) or a fan beam coupled to
a linear array of detectors (second
generation). The pencil-beam scanner
performs a two-dimensional raster scan,
while the fan-beam scanner performs
a single sweep across the patient.

Nuclear
Medicine |
|
Nuclear medicine is a healthcare specialty
involving the use of radioactive compounds
to perform diagnostic imaging examinations
that can lead to the effective treatment
of many diseases. Although nuclear medicine
is often considered an independent discipline,
it is closely related to radiology in
that radiation is used to develop images
of human anatomy.
Nuclear medicine imaging tests differ
from most other imaging modalities in
that the tests primarily show the physiological
function of the system being investigated
as opposed to the anatomy. In some centers,
the nuclear medicine images can be superimposed
on images from modalities such as CT
or MRI to highlight which part of the
body the radiopharmaceutical is concentrated
in. This practice is often referred
to as image fusion.
