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 recent association survey found that about 75% of radiologist members had not yet been able to reduce their imaging backlogs. Another 30% said they believe wait times may never return to pre-pandemic levels.

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 of special interest in MS, where morphologic MRI cannot depict major parts of disease activity.

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 appearances on such scans. It can be difficult for a radiologist to accurately differentiate between the two, but doing so is pertinent to a patient’s treatment plan.

The researchers proposed using a fully automatic pipeline of convolutional neural networks (CNNs) and capsule networks to assist radiologists in discerning between COVID and CAP.

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 life-saving and emergency procedures are performed by the interventional radiologist. Interventional Radiology is complementing the other stakeholders by becoming the fourth pillar of cancer care.

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 of comorbidity in COVID cases.

Chest radiograph and CT is to be used in very select situations such as clear cut at the shortness of breath and hypoxia, persistent fever, discordance between clinical, microbiology and high-risk situations it is not a routine investigation bit having done it can give out lots of information.
