Radiologic Investigation

We are able to do almost all Radiologic Investigation on the same day including MRI and CT-Scan. Speak to our staff for more info.

X-ray

X-rays are a type of electromagnetic radiation, just like visible light.

An x-ray machine sends individual x-ray particles through the body. The images are recorded on a computer or film.

Structures that are dense (such as bone) will block most of the x-ray particles, and will appear white.
Metal and contrast media (special dye used to highlight areas of the body) will also appear white.
Structures containing air will be black, and muscle, fat, and fluid will appear as shades of gray.

X-ray is mostly used to detect the bone fracture, bone structure, foreign body, or metal implant.

CT-Scan

A computed tomography (CT) scan is an imaging method that uses x-rays to create pictures of cross-sections of the body.

A CT scan creates detailed pictures of the body, including the brain, chest, spine, and abdomen. The test may be used to:
- Diagnose an infection
- Guide a surgeon to the right area during a biopsy
- Identify masses and tumors, including cancer
- Study blood vessels

Magnetic Resonance Imaging (MRI)

Magnetic Resonance Imaging or MRI is a medical diagnosis technique that creates images of the body using a magnetic field and radio waves.

It does not use X-rays. A versatile, powerful and sensitive tool, MRI can generate thin-section images of any part of the body from any angle in a relatively short period of time.

MRI is a completely non-invasive procedure, and there are no known side or after effects. The procedure is painless.

BENEFITS:
- Images of the soft-tissue structures of the body such as meniscus, anterior cruciate ligament (ACL), lumbar discs and ligaments are clearer and more detailed than with other imaging methods.
- MRI can help physicians evaluate the function as well as the structure of many organs.
- The detail makes MRI an invaluable tool in early diagnosis and evaluation of tumours.
- MRI contrast material is less likely to produce an allergic reaction that the iodine-based materials used for conventional investigation.
- MRI enables the detection of abnormalities that might be obscured by bone with other imaging methods.
- MRI provides a fast, non-invasive alternative to x-ray angiography for diagnosis problems of the knee and spine system.
- Exposure to radiation is avoided.

RISKS:
- An undetected metal implant may be affected by the strong magnetic field.
- MRI is generally avoided in the first 12 weeks of pregnancy. Doctors usually use other methods of imaging such as ultrasound, on pregnant women unless there is a strong medical reason to use MRI.

Ultrasound

Ultrasound (US) imaging, also called ultrasound scanning or sonography, is a method of “seeing” inside the human body through the use of high-frequency sound waves. The sound waves are recorded and displayed as a real-time visual image. No ionizing radiation is involved in ultrasound scanning.

BENEFITS:
- Ultrasound scanning is non-invasive (no needles or injections in most cases) and is usually painless.
- Ultrasound is widely available and easy to use.
- Ultrasound imaging uses no ionising radiation and is preferred image modality for diagnosis and monitoring of pregnant women and their unborn infants.
- Ultrasound provides real-time imaging, making it a good tool for guiding minimally invasive procedures such as needle biopsies.
- Ultrasound images can visualise structure and blood vessels.

RISKS:
- For standard diagnostic ultrasound there are no known harmful effects on human.

Bone Mineral Density (BMD)

Bone mineral densitometry (BMD), also called dual-energy x-ray absorptionmetry (DEXA) is an x-ray examination that is used to measure bone loss. DEXA is today’s established standard for measuring bone mineral density.

BMD is most often used to diagnose osteoporosis. Osteoporosis, which means “porous bone” is a disease in which there is a loss of bone tissue. This makes bones brittle and more prone to breakage. Some common causes of osteoporosis includes:
- Lack of physical activity
- Inadequate calcium in the diet
- Menopause
- Simultaneous illness, hormonal irregularities and thyroid disorders

BMD is also effective in tracking the effects of treatment for osteoporosis and other conditions that cause bone loss.
