This makes them crucial in handling time-sensitive neurological conditions such as strokes.
For example, Hyperfine’s development of the Swoop system has revolutionized portable MRI by integrating ultra-low-field magnetic resonance, radio waves, and artificial intelligence (AI). This system enables MRI scans to be performed at the POC, enhancing access to neuroimaging for critically ill patients. It is controlled via an Apple iPad Pro and can be set up within minutes, making it a practical tool for brain imaging in settings such as intensive care units (ICUs), pediatric wards, and other healthcare environments. The Swoop system is versatile and can be used for various conditions, including stroke, ventriculomegaly, and intracranial mass effects.
X-Ray: Mobile X-ray machines are designed to be lightweight, foldable, battery-operated, and compact, making them ideal for POC imaging. These devices are equipped with advanced image processing features and noise-reduction circuits that minimize signal interference and attenuation, producing clear X-ray images that offer high diagnostic value to healthcare professionals. The World Health Organization (WHO) notes that combining portable X-ray systems with AI-powered computer-aided detection (CAD) software greatly boosts diagnostic accuracy, efficiency, and effectiveness. WHO’s backing could play a crucial role in enhancing tuberculosis (TB) screening, especially in regions like the UAE, where 87.9% of the population consists of international migrants, many of whom come from TB-endemic areas.
Portable X-ray systems have a wide range of clinical uses, including diagnosing pneumonia, lung cancer, fractures, heart disease, kidney stones, infections, and pediatric conditions. These advanced mobile X-ray machines use high-frequency X-rays for precise delivery and superior image quality. For instance, Prognosys Medical Systems in India has introduced the Prorad Atlas Ultraportable X-ray system, a lightweight, portable device that features a microprocessor-controlled high-frequency X-ray generator, ensuring accurate X-ray output and top-quality images.
In particular, the Middle East is seeing rapid growth in mobile medical imaging, as international companies recognize its value and rising demand in the region. A notable example is the February 2024 partnership between the US-based United Imaging and Saudi Arabia’s Al Mana Group. This collaboration will see AI Mana Hospital positioned as a training and strategic center for digital mobile X-rays across Saudi Arabia and the wider Middle East.
Ultrasound: Mobile ultrasound technology encompasses a variety of devices, including wearable, wireless or wired handheld scanners and cart-based ultrasound machines featuring flexible, compact ultrasound arrays alongside linear and curved transducers. These scanners utilize artificial intelligence algorithms to identify various structures within the human torso, adjusting parameters such as frequency and depth of penetration automatically to enhance imaging quality. They are capable of conducting both superficial and deep anatomical imaging at the bedside, while also expediting data processing. This capability allows for detailed patient images that are critical for diagnosing conditions like decompensated heart failure, coronary artery disease, congenital fetal abnormalities, as well as pleural and pulmonary diseases. The teleultrasound functionality enables healthcare providers to share real-time images, videos, and audio with other medical professionals, facilitating remote consultations to optimize patient care. An example of this advancement is GE Healthcare’s introduction of the Vscan Air SL handheld ultrasound scanner at Arab Health 2024, designed to provide both shallow and deep imaging with remote feedback capabilities for swift and precise cardiac and vascular evaluations.
To promote the use of mobile ultrasound scanners, healthcare organizations in the Middle East are concentrating on enhancing the skills of their medical personnel through cutting-edge technology training. For instance, Sheikh Shakhbout Medical City, one of the largest hospitals in the UAE, established a point-of-care ultrasound (POCUS) academy in May 2022. This initiative aims to equip medical practitioners with AI-assisted POCUS devices to improve bedside patient examinations. Additionally, in February 2024, SEHA Virtual Hospital, one of the largest virtual healthcare facilities globally, successfully executed a landmark teleoperated ultrasound scan using Wosler’s Sonosystem. This event highlighted the telemedicine platform’s capability to enable healthcare professionals to provide timely and accurate patient care from any location.
CT: Mobile CT scanners are equipped to conduct full-body scans or target specific areas, such as the head, producing high-quality cross-sectional images (slices) of internal organs. These scans aid in identifying medical conditions including strokes, pneumonia, bronchial inflammation, brain injuries, and skull fractures. Mobile CT units minimize noise and metal artifacts, yielding improved contrast and clarity in imaging. Recent advancements include the incorporation of photon counting detectors (PCD) that provide ultra-high-resolution scans with remarkable clarity and detail, enhancing disease diagnosis. Moreover, an additional laminated lead layer in the mobile CT scanners helps reduce radiation scattering, offering operators increased protection and mitigating the long-term risks associated with radiation exposure.
For example, Neurologica has introduced the OmniTom Elite PCD scanner, which offers high-quality, non-contrast CT imaging. This device enhances differentiation between grey and white matter and effectively eliminates artifacts like streaking, beam hardening, and calcium blooming, even in difficult cases.
The Middle East faces significant challenges with cerebrovascular diseases, particularly strokes, with countries such as Saudi Arabia showing a high age-standardized stroke prevalence (1967.7 cases per 100,000 population). To address this public health issue, SEHA Virtual Hospital is providing virtual stroke care services utilizing CT scans, which aim to enhance diagnostic accuracy and expedite medical interventions to improve patient health outcomes.
