Mapping the cerebral vascular network in human patients, at unprecedented scales: This tour de force has been achieved by the French laboratory Physics for Medicine Paris (ESPCI Paris-PSL, Inserm, CNRS). In a study published on the front page of Nature Biomedical Engineering, the research team details its method—ultrasound localization microscopy, which combines ultrafast sonography and […]
Menorrhagia is a symptom of an underlying pathology in many women. It is defined as excessive bleeding (over 80 ml of blood per period), for over 7 days and at regular intervals. Causes of Menorrhagia Causes of Menorrhagia may be due to specific disease, hormonal, uterine or reproductive anatomical abnormalities or caused due to drugs […]
Endoscopic retrograde cholangiopancreatography (ERCP) is a medical technique that is used primarily to investigate and treat pathologies involving the biliary tree and pancreatic ducts. Indications which could warrant need for ERCP include gallstones, tumors, defective sphincters, sclerosis of ducts and pseudocysts, which are accumulations of fluid and tissue components. ERCP has been traditionally used for […]
An experimental treatment may have “jump-started” the brains of two patients who had been in a minimally conscious state for months following a coma, according to a new study. Both patients had severe brain injuries and had shown only limited signs of consciousness for more than a year. But after receiving the treatment — which […]
(HealthDay)—Optic nerve ultrasonography can help diagnose increased intracranial pressure with high specificity and sensitivity for patients with traumatic and nontraumatic brain injury, according to a review published online Nov. 19 in Annals of Internal Medicine. Alex Koziarz, from University of Toronto, and colleagues conducted a systematic review to examine the accuracy of optic nerve ultrasonography […]
A new study of ultrasound departments shows that continuous personnel changes are a major cause of the now serious shortage of ultrasound staff in the NHS. This shortage has led to delays in diagnosis and cancellations of operations. The work is presented at the UK Imaging and Oncology Congress in Liverpool. “We have actually asked […]
The World Health Organization ranks Type 2 diabetes among the most common causes of death in the world. Current treatments can help the body use insulin at various stages of the disease, but they can also be expensive and subject patients to lifelong medication regimens and side effects. Thanks to new therapeutic ultrasound technology, one […]
Ovarian cancer is usually diagnosed only after it has reached an advanced stage, with many tumors spread throughout the abdomen. Most patients undergo surgery to remove as many of these tumors as possible, but because some are so small and widespread, it is difficult to eradicate all of them. Researchers at MIT, working with surgeons […]
Many types of cancer could be more easily treated if they were detected at an earlier stage. MIT researchers have now developed an imaging system, named “DOLPHIN,” which could enable them to find tiny tumors, as small as a couple of hundred cells, deep within the body. In a new study, the researchers used their […]
Researchers have made a breakthrough in more precisely targeting drugs to cancers. Using ultrasound and lipid drug carriers (liposomes), a multi-disciplinary team of biomedical engineers, oncologists, radiologists and anaesthetists at the University of Oxford have developed a new way to improve the targeting of cancer drugs to tumours. The new technology has been used in […]
