Magnetic Resonance Imaging is a technique which uses radio frequency signals to acquire its images and is best suited for soft (non-calcified) tissue exams. The technique uses powerful magnets to excite hydrogen nuclei in water molecules in human tissue, producing a signal which is then converted into a highly-detailed 2D thin "slice" image of the body.
X-Ray imaging in its simplest form uses electromagnetic radiation to capture a "shadow" on photographic film and is known as “projection radiography” or "plain film radiography". Bone and some organs (such as lungs) especially lend themselves to projection radiography. In Computed Radiography (CR) the photographic film is replaced by an imaging plate which produces a digital image which can be displayed and stored and transmitted with ease.
Medical Ultrasound uses high frequency sound waves of between 2.0 to 10.0 megahertz that are reflected by tissue to varying degrees to produce a 2D image. While it may provide less anatomical information than techniques such as CT or MRI, it has several advantages which make it ideal as a first line test in numerous situations, in particular that it studies the function of moving structures in real-time. Ultrasound scanners are portable making this technique convenient for Primary Care applications.
Computed Tomography is a technique which uses, X-rays, to acquire its images, making it a good tool for dense tissue (bone) exams to acquire its image. Unlike normal projection X-ray, CT scanning uses an X-ray source that rotates around the object to produce a thin “slice” image. CT completely eliminates the superimposition of images of structures outside the area of interest. Additionally it is very high resolution, being able to distinguish between tissues that differ in physical density by less than 1%.
OrthoPanTomoGram 'Ortho' as in orthodontics refers to the teeth. 'Pan' refers to the panoramic display of the teeth produced by the technique. A 'Tomogram' is an X-ray image that is focussed in a single plane of the patient. The OPG machine is specifically designed to produce panoramic tomographic X-rays of the teeth, jaws and temperomandibular joints. The images provide an overview of the state of the teeth as well as information regarding the bones of the jaw, the sinuses and the joints between the jaw and the skull.
Bone Densitometry (DXA or DEXA) Scanning A Bone Densitometry Scan is a painless test that measures the density of bones. DEXA stands for dual energy X-ray absorptiometry. Generally, the denser your bones are the stronger they are, and the less likely they are to break. DEXA scans help find out whether you have osteoporosis or are at risk of developing it. They can also be used to detect other bone disorders and conditions, and to monitor the relative amounts of body fat and muscle in your body.

Why choose Global Diagnostics?

It's simple – it’s fast and efficient.

Many medical conditions require rapid diagnosis and treatment. When the health of you or your patients is at stake you don’t want to increase risk with unnecessary waiting times.

How do we do it?

In a word - the Internet! We use the phenomenal power of the Internet to bring together patient and expert diagnostician. Internet technology is now so advanced that it can be used to transmit large images across the globe reliably and securely. We use a combination of 128 bit encryption (as used by banks and financial institutions) and a system known as RIS-PACS (Radiology Information System and Picture Archiving and Communication System). This technology allows us to transmit patient data and digital images of their scans to anywhere in the world for diagnosis. All the diagnostician then needs to produce a diagnostic report is a standard desktop computer and broadband connection. A completely paperless desktop-to-desktop diagnostic service!!
