Vienna's 20th ECR: Hidden gems and other reflections
ECR 2014, which begins on 6 March, is the 20th ECR to be held in Vienna. Four European radiologists, including three members of AuntMinnieEurope.com's editorial advisory board, reflect on their first ECR, why they keep returning, and what changes they have observed, and also reveal their hidden or forgotten gems from Vienna.

DL algorithm targeting prostate cancer demonstrates clinical impact
By Liz Carey
Per participant, a deep-learning (DL) algorithm demonstrated increased specificity of 64.8% compared with radiologists at 21.3%.

MRI scans show two areas of clinically significant prostate cancer in a 65-year-old man with a prostate-specific antigen level of 8.23 ng/mL. Images are (A, E) axial T2-weighted images, (B, F) axial diffusion-weighted images obtained with a b value of 1500 sec/mm2, (C, G) axial apparent diffusion coefficient images, and (D, H) lesion masks generated by the deep learning algorithm (DLA) on T2-weighted images. The DLA detected a lesion in the right posteromedial peripheral zone of the apex (D), which was assigned as Prostate Imaging Reporting and Data System (PI-RADS) 4. A radiologist also detected the lesion and assigned it PI-RADS 4 (arrow in A-C). A lesion in the right anterior transition zone (H) was detected by the DLA, which was assigned PI-RADS 4. The radiologist did not detect the lesion (arrow in E-G). Both lesions were confirmed as prostate cancer with Gleason grade group 2. Caption and image courtesy of RSNA.

An example that features an AI-generated report that identified “scattered pulmonary granulomatous calcifications.” In the first session, three of five readers specifically reported the presence of a nodule. Following the introduction of the AI-generated report, only one reader maintained the specific mention of a nodule, whereas the other four readers adapted their reports to include the AI-suggested terminology of “granulomatous calcifications.” AP = anterior-posterior.

CEM improves breast cancer detection rate over low-energy mammography
By Amerigo Allegretto
Contrast-enhanced mammography (CEM) improves breast cancer detection over low-energy mammography in screening settings.

Images depict true-positive findings in a 51-year-old woman with a left breast focal nonmass enhancement. (A) Mediolateral oblique and (B) cranio-caudal contrast-enhanced mammographic (CEM) images show the enhancement (arrows). No correlate was identified on (C) mediolateral-oblique or (D) craniocaudal low-energy images, or whole-breast ultrasound (not shown). Contrast-enhanced breast MRI shows a suspicious enhancement on (E) sagittaland (F) axial subtraction images (arrows), correlating with the finding on CEM images. MRI-guided biopsy (not shown) showed flat epithelial atypia, withsubsequent surgery confirming ductal carcinoma in situ.
