Diagnostic Imaging


Diagnostic imaging is an integral part of the assessment of a patient’s health and includes utilising a combination of several medical imaging modalities.  These include ultrasound, magnetic resonance imaging and computed tomography amongst others. Advancement in medical imaging provides a more accurate diagnosis and personalised approach towards the patient’s treatment plan through the use of big data. This diagnostic imaging revolution has created greater clarity in 3-D medical imaging: significant advancements include open and portable magnetic resonance imaging (MRI) scanners to remove patient anxiety caused by a claustrophobic and noisy magnetic tunnel. Today, the usage of open MRI machines make them less restrictive and more accessible on the sides and therefore able to accommodate heavier patients.  In addition, researchers have developed a superconducting magnet system that fits into the palm of a hand: this compares is to the sizeable superconducting magnet used in standard MRI scanners.  Consequently, these compact superconducting magnets can be used in portable and mobile MRI scanners.  Big data analytics are transforming healthcare and will provide healthcare professionals with real-time data during the imaging process. The benefits of this approach will lead to a reduction in errors and a more personalised approach towards the patient’s care plan. Advanced analytics can be used to detect certain patterns regarding pathology. The imaging algorithms can convert these patterns into a digital image which is reviewed by the radiologist to provide a more accurate diagnosis. Such so called big data in diagnostic imaging will contribute to providing advancements in radiology information and PACS systems; especially by using the cloud. Other emerging technologies include the use of 3D and 4D in diagnostic radiology to create more high-resolution images.  This is shown by ultrasound imaging which is limited by its inability to obtain high-resolution, detailed images. However, by using 3-D metamaterial to achieve deep-subwavelength imaging, initial studies suggest that ultrasound resolution can be enhanced by a factor of 50.  This approach to the improvement of ultrasound resolution will effectively improve patient care.  Furthermore, 3-D capability in computed tomography scans using software that substantially enhances the contrast of soft tissue and thereby reducing the visibility of metal artefacts is an improvement compared to traditional CT images.
