WHAT IS MRI?
MRI, Magnetic Resonance Imaging, is a method used by physicians to look inside the human body to obtain diagnostic information. Incorporating an advanced technology, MRI produces images of the anatomy without the use of radiation as in x-ray and CT scanning.
MRI utilizes the physical properties of magnetic fields, radio waves and computers to generate images of the soft tissues within the body in any plane. This technique is now commonly used as a primary diagnostic tool. It can help provide a quick and more accurate diagnosis for your physician which might have associated risks.

Open Magnetic Resonance Imaging (Open MRI) is an advanced diagnostic imaging procedure that creates detailed images of internal bodily structures without the use of ionized radiation (x-rays). Open MRI is able to produce these detailed images through the use of a powerful magnet, radiowaves and a computer. MRI can assist physicians in detecting and diagnosing diseases or other abnormalities in very early stages.Claustrophobic, obese and pediatric patients, along with those suffering from post-traumatic stress syndrome, are often able to comfortably undergo MRI examinations in the “open architecture” systems while failing to tolerate traditional “closed” MRI systems. Open systems are quieter and more comfortable for patients. Open MRI systems are rapidly becoming a preferred choice for many healthcare consumers.

ULTRASOUND
An ultrasound is a diagnostic procedure that uses high frequency sound waves to image the body. Unlike an x-ray, an ultrasound procedure does not use radiation. Instead, a small microphone-like transducer is placed on the area of interest. High frequency sound waves are emitted and produce echoes from the internal tissues and organs. The transducer converts the echoes to electric signals to create an image.
While this procedure is generally used in pregnancies and is considered one of the best methods for viewing an unborn child, it is also used to image the gallbladder, liver, kidneys, pancreas, uterus, ovaries, prostate, testicles, thyroid, and breasts. Ultrasound can also look at and listen to the blood flow within arteries and veins in the neck, abdomen, and legs and the valves and chambers of your heart.

BONE DENSITOMETRY
 Bone Densitometry is a simple and non-invasive procedure that is used to measure bone mass and assist in the diagnosis of osteoporosis. Osteoporosis is a disorder of the bones characterized by a progressive loss of bone tissue, which can result in an increase in the risk of fractures, often from minor falls or spills that would not normally result in a fracture.
By utilizing a very low dose of x-rays, the Bone Densitometry machine produces an image of your bones and calculates the strength of the bones. The test is painless and simple to conduct and has minimal radiation exposure. Bone Densitometry is also useful in tracking the progression of osteoporosis.

RADIOGRAPHY (X-RAYS)
Radiography, known to most people as
x-rays, is the oldest and most frequently
used form of medical imaging.
For nearly a century, diagnostic images
have been created by passing small,
highly controlled amounts of radiation
through the human body, capturing the
resulting shadows and reflections on
a photographic, or digital, plate.
X-Rays allow physicians to perform
a quick evaluation, often detecting
diseases in the early stages, where
the chance for recovery is improved.
X-rays can also rule out the presence
of disease, reduce the need for invasive
surgery, and provide a guide for surgeons
when surgery is unavoidable. |

 CT
SCANS
Computed Tomography (CT or CAT Scan) is a
state-of-the-art diagnostic procedure using
x-rays that rotate around the patient and
produce a series of cross-sectional images
of selected parts of the body. Once the scanner
has made several of these images, its powerful
computer combines part of the different pictures
to create cross sectional views of the body.
These images provide physicians with an unobstructed
look at organs and structures not seen clearly
on conventional x-rays.
