  2. Developed at Hong Kong Polytechnic University (PolyU), the palm-sized Scolioscan Air device (which weighs just five kg), consists of a wireless ultrasound probe with a compact optical marker mounted on it and a depth camera that serve as a spatial sensor, which help to dramatically downsize the device. The optical 3D spatial tracking method provides a high degree of accuracy, comparable to the predictive full-size Scolioscan system, also developed at PolyU. The dramatically reduced material cost, size, and weight allow Scolioscan Air to be carried within a suitcase.In addition to the hardware technology, a software suite installed on a dedicated laptop or tablet device facilitates 3D ultrasound image reconstruction, visualization, and measurement, including automatic curvature measurement and spinal deformity analysis software. Clinical trials prove the technology as very reliable, with the accuracy of curve measurement comparable to that of X-ray assessment. In addition, Scolioscan Air can obtain image in any postures, provide vertebra rotation and muscle-related information, and form a 3D spinal model for analysis of spinal deformity.“We can now literally bring the device and mass screening service to the youngsters anywhere, anytime. It would facilitate the implementation of school-based scoliosis screening to detect and treat spinal curvatures before they become severe enough to cause chronic pain or other health issues among adolescents,” said Professor of biomedical engineering Zheng Yong-ping, PhD. “When providing non-surgical treatment for scoliosis patients, healthcare personnel can use Scolioscan Air to conduct real-time assessment, so as to optimize the treatment outcome.”Scoliosis is a medical condition in which the spine is curved from side to side. Although it is a complex 3D deformity, on an X-ray, viewed from the rear, the spine of an individual with scoliosis looks more like an "S" or "C" shape than as a straight line. Scoliosis is classified as congenital, idiopathic, or neuromuscular, when it has developed as a secondary symptom of another condition, such as spina bifida, cerebral palsy, spinal muscular atrophy, or physical trauma.

  3. Developed by Clarius Mobile Health (Clarius; Burnaby, BC, Canada), Clarius Live is a new, simple-to-use feature that allows any user of Clarius Ultrasound scanners to easily request real-time assistance from a colleague via an app while actually performing an ultrasound exam. The feature is already fully integrated into the current version of the Clarius app and is activated with a single tap on the screen, which opens a prompt to enter an email address or phone number to connect with anyone around the world.The receiver is notified with a secure link from Clarius by SMS or email. The call is then accessible from any smart device or desktop computer with an internet connection. Recipients can point to areas of interest with their cursor, and the pointer will be highlighted on the scanning screen. A two-way audio communication is also available during live evaluation of ultrasound image. The receiver does not need any additional apps, accounts, or hardware. Clarius Live is currently available on Apple (Cupertino, Ca, USA) iOS for all Clarius users, for up to 60 minutes a month.“What I think is really good about it is that it's really simple. It's like sending a text through the phone,” said OrianaTolo, director of education at ZEDU Ultrasound Training (Melbourne, Australia), upon experiencing Clarius Live on her own device for the first time.“There is so much excitement behind this feature because, it opens up many opportunities for remote education and rural medicine, facilitating collaboration between colleagues thousands of miles apart,” said Dave Willis, co-founder and chief strategic officer of Clarius Mobile Health.The Clarius C3 and L7 wireless ultrasound handheld ultrasound scanners use secure point-to-point wireless networking to connect to the Clarius app. The Clarius C3 is a multipurpose ultrasound scanner for imaging the abdomen and lungs; it also incorporates a virtual phased array for quick scans of the heart. The Clarius L7 is intended for guiding interventional procedures, such as nerve blocks and targeted injections, and for imaging superficial structures. Video

  5. For the colon trial, researchers at University College London (UCL, United Kingdom), Frimley Park Hospital, (Frimley, UK) recruited 370 patients, of whom 299 completed it. For the lung trial, they recruited 353 patients, of whom 187 completed the trial. Study participants were followed up for 12 months to better evaluate the accuracy of whole-body MRI compared with standard tests, by comparing pathway sensitivity and specificity, and to retrospectively evaluate what the optimal treatment decision should have been.The results revealed that in the colon trial, pathway sensitivity was 67% for whole-body MRI and 63% for standard pathways, a difference in sensitivity of 4%. Specificity did not differ between whole-body MRI (95%) and standard pathways (93%); no imaging-related adverse events were reported. In the lung trial, pathway sensitivity was 50% for whole-body MRI and 54% for standard pathways, a difference of 4%. Specificity, again, did not differ between whole-body MRI (93%) and standard pathways (95%). Similarly, no adverse events related to imaging were reported. The two studies were simultaneously published on May 9, 2019, in Lancet Respiratory Medicine and Lancet Gastroenterology and Hepatology.“Our results, obtained in a real-world NHS setting, suggest that whole-body MRI could be more suitable for routine clinical practice than the multiple imaging techniques recommended under current guidelines,” said lead author Professor Stuart Taylor, of UCL. “While demands on NHS MRI scanners are currently high, MRI can image the whole body in one hour or less. Adopting whole-body MRI more widely could save rather than increase costs, as well as reducing the time before a patient’s treatment can begin.”Whole-body MRI is increasingly being used as an all-in-one diagnostic tool for of a variety of malignant diseases, including multiple myeloma, systemic musculoskeletal diseases, bronchial carcinoma, hepatic malignancies, renal carcinoma, colon cancer, lymphoma, and also rare malignancies such as bone or soft tissue tumors. It can also aid in the early diagnosis of some systemic diseases, such as diabetes and atherosclerosis. Lack of major side effects is a major consideration for MRI screening, with the only potentially consequent sources related to intravenous (IV) contrast agents. THE END
