Diagnostic Radiological
examinations that are offered at our centre includes:
General X-rays
A form of invisible electromagnetic energy of
short wavelength that is produced when High-speed electrons strike a
heavy metal.
X-rays are used to produce images of the bones,
organs and internal tissues of the body.
Computerised Tomography (CT)
This diagnostic procedure combines the use of
computers and X-rays as it passes through the body at different
angles to produce clear images of sections of tissues being
examined. CT scanning or whole body scanning provides clearer and
more detailed images than X-rays used by themselves.
CT has marked major advantages in the diagnosis
and treatment of tumours, abscesses and hemorrhages of the brain, as
well as strokes and head injuries.
Besides being essential for studies of the brain,
CT scanning is invaluable in investigating diseases of the trunk,
particularly in locating a tumour to assist in the process of a
needle biopsy.
With the advent of spiral or helical CT, even
faster throughput is achievable with enhanced picture quality
thereby improving patient care.
Mammography
This is a special diagnostic X-ray procedure of
the breasts and is a gold standard in the early detection of breast
cancer.
With our film screen technique, high quality
mammograms are obtained with the least possible radiation to the
breasts.
Mammography is also used to aid in the diagnosis
of established benign breast diseases and help plan management of
patients.
Ultrasound
Ultrasound is a diagnostic procedure in which very
high frequency sound waves (inaudible to the human ear) are passed
through the body. The reflected echoes are detected and analyzed to
build a picture of the internal organs or of a foetus in the uterus.
This procedure is considered painless and safe, not to mention real
time.
Ultrasound is used to examine soft organs like the
liver, gallbladder and the pelvic region to detect any abnormality.
As a soft tissue imaging technique, its advantages
are as follows:
- It is non-invasive and does not usually
require special patient preparation. It is simple and convenient
and easily accepted by most patients including children.
- It is safe for the patient and the
operator as it does not require ionising radiation. Examinations
can be safely repeated as often as the clinical situation
demands.
- It provides information on structural
boundaries as it demonstrates anatomy rather than function. Most
organs can be investigated and their shape, size, position and
spatial relationship can be determined. It enables tissues to be
differentiated on the basis of their interaction with
ultrasound.
- Cystic structures may be readily
distinguishable from solid ones. It can be used to detect and
examine moving structures and the pattern of movement can be
determined. The pulsation of the fetal heart may be identified
as early as 7th week of gestation. This is an extremely useful
test of fetal viability in cases of threatened abortion.
- The use of ultrasonic doppler technique
to study flow patterns in arteries and veins is now well known.
It is possible to detect changes in flow speed and direction and
thus to evaluate many of the diseases of the arterial and venous
system.
Bone Densitometry
The procedure measures bone density, as determined
by the concentration of calcified material in the bone.
The test is used to confirm the presence of
osteoporosis (bone loss). Backache, sports injuries, anyone
undergoing hormonal treatments and all general nondescript bone pain
could warrant bone densitometry. It is also useful in assessing the
response to treatment of these conditions.
Bone densitometry or BMD can be performed with a
CT scan using a single or dual photon absorption technique.
Intravenous Urography
This procedure involves an injection of a dye into
the veins to study the urinary tract. Some clinical indications
include haematuria (blood in the urine), renal stone etc.
