CTPA-based prediction model nails pulmonary hypertension
VIENNA - When do suspected pulmonary embolism patients actually have pulmonary hypertension (PH)? Although the treatment approach for the conditions is quite different, their presentation can be similar. But a new CT pulmonary angiography (CTPA) tool can accurately predict PH in patients without pulmonary embolism, according to researchers from Israel.

Italian men shun flexible sigmoidoscopy for CTC
VIENNA - Whether it's fear of endoscopes or love of high technology, Italian men appear more willing to undergo CT colonography (CTC) than flexible sigmoidoscopy, according to the results of a late-breaking trial presented at ECR 2015.

Figure: Improved image quality with a generative adversarial network architecture for low- to high-field-strength image translation, called LowGAN. (A–C) Top: High-field-strength (3-T) and low-field-strength (64-mT) images and LowGAN outputs for a single participant across (A) fluid-attenuated inversion recovery (FLAIR), (B) T1-weighted (T1w), and (C) T2-weighted (T2w) contrasts. Bottom: Graphs demonstrate the structural similarity index (SSIM), peak signal-to-noise ratio (PSNR), normalized cross-correlation (NCC), and feature similarity index (FSIM) between high field strength and low field strength (64-mT) and high field strength and LowGAN outputs. a.u. = arbitrary units.****p ≤ 0.0001.
