Understanding CT flow artifacts is key to better disease diagnosis
Understanding the mechanics of flow artifacts on CT or CT angiography (CTA) and how these artifacts are created is key to better disease diagnosis, according to a review published April 25 in RadioGraphics.
In the review, a team led by Caroline Robb, MD, of Mallinckrodt Institute of Radiology, Washington University in St. Louis, MO, described flow artifacts and how they are different from several types of conditions.
"At first glance, flow artifacts may appear as a simple distractor to the discerning eye of a radiologist," Robb and colleagues noted. "However, there are many instances when identification of these artifact...

What Causes Hemoptysis?
Discussion
True hemoptysis is a very uncommon or rare problem in pediatrics but can be potentially life-threatening. Massive hemoptysis has a high mortality (up to 50%) mainly from asphyxia and inability to ventilate and oxygenate the patient because of blood in the pulmonary airways. Fortunately, most hemoptysis is small in amount that resolves within 24 hours.
Initial evaluation for hemoptysis can include complete blood count, coagulation studies, C-reactive protein, erythrocyte sedimentation rate, urinalysis (possible pulmonary-renal problems), radiographic imaging including chest x-ray and/or computed tomography, and...

Can Chat GPT accurately refer patients to IR for treatment?
Chloe Cross, MD, of Icahn School of Medicine at Mount Sinai in New York City.In interventional radiology (IR), most of us quickly become accustomed to needing to explain what we do -- to other clinicians, patients, their families, and even our own families. But how do patients get their own information about IR, if at all? When a patient receives a diagnosis, they may have multiple medical specialists offering various treatment recommendations, so they may be unsure which to follow.If patients search for information using new tools like artificial intelligence, what is it telling them? How much does AI know about IR? Does ...

Avicenna.AI secures FDA clearance for CINA-iPE and CINA-Aspects
Medical imaging AI company Avicenna.AI has received 510(k) clearance from the U.S. Food and Drug Administration (FDA) for its CINA-iPE and CINA-Aspects software.
CINA-iPE is an AI-powered tool that detects incidental pulmonary embolism during routine CT scans. The algorithm identifies lung blood clots detected during routine CT scans for a variety of health conditions. Scan types may include full-body scans, scans of the chest, abdomen, and pelvis, as well as scans of the thoracic area along with the abdomen and pelvis.
CINA-Aspects is for stroke severity assessment, automatically processing non-contrast CT scans and cal...

CTPA rates increase among pregnant women
The use rate of CT pulmonary angiography (CTPA) for the diagnosis of pulmonary embolism (PE) has increased among pregnant women -- but outcomes from these studies are often negative, researchers have reported.
A team led by Sameer Goyal, MD, of Northwell Health, Manhasset, New York, discovered that the rate of CTPA exams for PE among pregnant patients increased by more than 70% over a 10-year time period without a simultaneous increase in positive findings -- results that underscore the importance of assessing the risk of radiation exposure in this group. The study findings were published March 18 in the Journal of the A...

NLP model used with radiology reports identifies PE patients
A natural language processing (NLP)-based model using information from radiology reports can accurately identify patients presenting in the emergency department (ED) with suspected pulmonary embolism (PE), researchers have found.
The study results could help clinicians determine appropriate treatment, wrote a team led by Krunal Amin, MD, of Duke University School of Medicine in Durham, NC. The group's findings were published March 2 in the Annals of Emergency Medicine.
"[Our work suggests that] a natural language processing-based clinical decision support tool … can identify patients presenting to the emergency departm...

ECR: More anatomical changes seen on angio-CT in COVID patients
Patients with COVID-19 experience a higher incidence of anatomical changes at the cardiac level on pulmonary angio-CT, suggest findings presented February 29 at ECR 2024. In her presentation, Ana Filipa Colucas, MD, PhD, from the University of Algarve in Faro, Portugal, discussed her team’s findings, which also showed how the use of pulmonary angio-CT scans has increased since the COVID-19 pandemic. “There were more changes in the diameter of the pulmonary artery trunk and the right ventricle in patients in the 41 to 60 years age group and in males,” Colucas said. Previous studies suggest an association between CO...
