Special Examination Modalities

What are special examination modalities?

Special examination modalities are imaging modalities such as Magnetic Resonance Imaging (MRI), CT Scan, Angiography and others which are available at the Diagnostic Imaging Department.

The examination modalities are divided into two areas which are

  • General examination modality
  • Special examination modalities
General Examination Modality

Is an imaging equipment used for the X-ray examination of the chest, upper and lower limbs, abdominal area, the spine, pelvic bone and others.

This examination is taking lesser time compared to the special examinations and does not require appointment and special preparation.

Special examination modalieties

Are imaging modalities used for special examinations.

These examinations often take longer time and require an appointment with specific patient preparation.

The type of special examinations are as follows:

  • Fluoroscopy

   Is a machine used to study the following :

– for the gastrointestinal tract examinations such as barium enema, barium swallow, barium meal and related examinations would be performed ; and

– for the urinary tract, examinations such as Micturating Cystourethrography (MCU) and related examinations would be performed ; and

– for the reproductive system, examinations such as Hysterosalpingography (HSG) and related examinations would be performed.

  • Mammography

It is a special examination carried out to detect tumours and other abnormalities of the breast.

  • Computed Tomography (CT Scan)

Computed tomography (CT scan) is a series of X-rays taken from different angles with a computer processing to make cross-sectional images of bone and tissue.

  • Orthopantomography (OPG)

Special examination that is able to visualise the panoramic image of the maxillary sinuses, the lower and upper teeth, the upper and lower jaw, nostrils and the temporo-mandibularjoints.

  • Ultrasound

Is a radiological examinations of the organs and limbs using high frequency sound waves without the risk of ionising radiation.

  • Magnetic Resonance Imaging (MRI)

An examination that uses magnetic field and radio waves to produce an image. The image produced is clearer to visualise organs and tissues.

  • Interventional Radiology / Angiografi

It is speacial procedure to diagnose and treat diseases of nearly every organ / system by being able to visualise internal structures or lumen, blood vessels and related organs.
