Dear Advanced Visualization Insider,
Body composition analysis has increasingly shown utility in a variety of clinical applications, including predicting health risks and mortality from total-body dual-energy x-ray absorptiometry exams, CT lung cancer screening exams, and even on routine abdominal CT exams in COVID-19 patients. It can also help to identify ovarian cancer patients who have a higher risk of chemotherapy complications.
In a study presented at last week's ECR 2022 Overture online meeting, researchers from Italy and Switzerland reported that three body composition measures on CT exams were significantly associated with chemotherapy complications such as delayed treatment cycles and early discontinuation of treatment in ovarian cancer patients. You can read all about it in this edition's Insider Exclusive.
Speaking of body composition analysis, researchers recently found that measurements of visceral adipose tissue on MRI exams were associated with a patient's cognitive function.
CT radiomics can be useful for predicting treatment response in patients with locally advanced rectal cancer, according to another presentation at ECR 2022 Overture. After developing a predictive model that includes analysis of radiomics, clinical, and pathological variables, researchers from China found that their method was highly accurate for forecasting response to neoadjuvant chemoradiation therapy.
Sometimes a little training can go a long way. After attending a one-day training course on CT colonography, radiologists demonstrated significant improvements in performance for interpreting these exams. Importantly, these gains were sustained over six and 12 months after the training.
Cinematic rendering can generate jaw-dropping, photorealistic images. But traditional volume-rendering technology still offers discernible benefits in CT scans of the facial skeleton.
Launching a radiology 3D printing laboratory can be complicated. It's worth the effort, though, to improve patient care, according to a recent article.
What do physicians outside of radiology think of advanced visualization techniques for viewing images? They tend to appreciate the value of 3D printing, virtual reality, or 3D displays, according to a study from Switzerland.
