Researchers are developing a modified MRI protocol to help treat brain hemorrhages

Researchers with the University of Texas Health Science Center at Houston are investigating how different MRI sequences can assist physicians in treating patients with brain hemorrhages.  With this MRI sequence, the team hopes to see within the hematoma what percentage of the blood is already clotted and what percentage is in the liquid form. It […]

Groundbreaking AI Technology Accurately Diagnoses COVID-19 Using Chest X-Rays in Minutes

A pioneering artificial intelligence (AI) technology is capable of accurately diagnosing COVID-19 in just a few minutes. The groundbreaking program developed by researchers at University of the West of Scotland (UWS; Scotland, UK) is able to detect the virus far more quickly than a PCR test, which typically takes around two hours. It is hoped […]

Eliminating Lenses: Ghost Imaging Speeds Up X-Ray Fluorescence Chemical Mapping

Researchers have developed a new, focus-free technique for creating chemical maps using x-ray fluorescence. The approach offers fast, high-resolution measurements, which could be useful for analyzing chemical composition for a range of applications in biomedicine. The new x-ray computational ghost fluorescence approach produces two sets of data for each photon energy — one with the […]

Novel Nuclear Imaging Probe Rapidly Assesses Treatment Response in Gastric Cancer

A novel nuclear imaging probe can measure a gastric cancer patient’s response to treatment within days, marking a potential breakthrough that could enable patients who aren’t responding to treatment to get moved quickly to potentially more effective therapies Current imaging modalities show tumor size, but it may take weeks before any perceptible change is demonstrated […]

Whole-spine MRI uncovers abusive head trauma injuries in children

Indiana University researchers analyzed imaging data on injuries in children seen at Riley Children’s Hospital in Indianapolis with suspected abusive head trauma. They found whole-spine MRI procedures showed additional abnormalities not identified on cervical spine MRI exams. Performing MRI of the whole spine in young children thought to be victims of abusive head trauma can […]

Radiologists warn of worsening imaging backlogs as omicron takes hold

Canadian radiologists are warning of worsening imaging backlogs as the omicron variant continues to spread.   Wait times for crucial diagnostic services have swelled well beyond the country’s recommended maximum of one month when the pandemic first started. Patients are reportedly now seeing delays upward of 82 days for CT scans and 89 for MRIs. A […]

7T Proton MR Spectroscopic Imaging Can Identify Brain Changes In Multiple Sclerosis

A recent study in the journal Radiology suggests that MR spectroscopic imaging at 7.0 T can identify changes in the brains of patients with multiple sclerosis (MS) that were not visible at T1- or T2-weighted MRI. Previous studies have shown that MR spectroscopic imaging (MRSI) allows in vivo assessment of brain metabolism. Also, it is […]

Convolutional neural network pipeline has 100% accuracy distinguishing between COVID and pneumonia

A fully automatic pipeline of convolutional neural networks and capsule networks was able to accurately differentiate between COVID-19 and community-acquired pneumonia (CAP) on chest CT images, according to new research. Chest CTs have been crucial in achieving a timely diagnosis for patients who present with symptoms consistent with COVID. However, COVID-19 and CAP have similar […]

Interventional radiology: Aiding advancements in cancer detection

Dr MC Uthappa, Head-Interventional Radiology, Manipal Group of Hospitals, Bangalore gave his insights on how Interventional Radiology is making Cancer Detection more accurate and safer for patients. Interventional Radiology involves no sutures and no scars with minimal pain. They are image-guided and have excellent clinical outcomes. Also, there are minimal complications. In many cases the […]

COVID-19: Radiology should be looked from point of comorbidity, says AIIMS’s top health experts

A discussion on radiology and COVID-19 was held in an interactive webinar session by the Union Health Ministry in collaboration with the All India institute of medical sciences (AIIMS). The discussion points out that although radiology is important when it comes to pneumonia, now it is important to look at radiology also from the point […]
