The All-Around-Radiology Community

The purpose of this Radiology community is to create a possibility, where most of the needs of radiologists, residents, medicals students, technologists and industry can be melted within one central Radiology network. It is based on a "taking and giving" principle, where you share your knowledge and others do the same.

Some features:

Share cases and your knowledge
Ask professionals for their opinion - in public or in private
Find people with similar interests, create new connections and expand your professional network
Discuss Radiology topics in dedicated forums - from residency to practice
Prepare for the Radiology boards
Find tutorials and eLearning material
Share your images, videos, teaching files and lectures
Simplify your research and find partners
Create or join research and study groups
General and Radiology specific search engines
Read Radiology news from multiple subspecialties
Publishing case reports (cooperation with the JRCR)
Helpful tools for your daily work (calculators, case tracker, clinical & research tools, etc.)
...and much more...

The best: IT'S FREE!

The founders of Radiolopolis developed in the past years several educational and clinical / practical programs (see image above), which where running separately. We recognized, that the full power of these programs can be best utilized when combined. That's how the idea of "Radiolopolis" was born. We will continuosly add and incorporate more programs into Radiolopolis, so that they can be seamlessly used by our "citizens" directly from this website.

Dare To Share! Radiology case and image exchange

A new program was launched on Radiolopolis: "Dare To Share!". Dare To Share! is a project, which allows sharing cases between researchers and colleagues. Users may find interesting or needed cases/images for different kind of projects (studies, books, publications, presentations etc.) while assuring the owner's credentials/copyright of the case. Direct contact between the searcher and the owner of the case provides also a good opportunity to get to know new, potential partners for future projects. More infos about the Dare To Share! program can be found here.

Flexner Report on Medical Education
A century ago this year, a Kentucky high school teacher wrote a report that had a dynamic effect on the shape and quality of American medical schools. His name was Abraham Flexner. By the time he undertook a study of medical schools in the United States and Canada, he had given up teaching and was a research associate at the Carnegie Foundation for the Advancement of Teaching. His brother, Simon Flexner, was the scientific director of the Rockefeller Institute, a philanthropic structure funded by the oil tycoon John D. Rockefeller. (Source: Academic Radiology)
Diagnostic and Surgical Imaging Anatomy: Ultrasound
by A. T. Ahuja et al, as the title suggests, is the ultrasound component in the Amirsys collection of textbooks for viewing, understanding, and, in this case, performing anatomical imaging. As with the entire series, the Ultrasound installment continues the excellence in image quality with the expanse of images for which they are known. In addition to the outstanding pictorial drawings, another hallmark of the Amirsys collection, there are also appropriate planar selections from computed tomography or magnetic resonance images providing further correlation to the sonographic images. The authors also take into account the unique imaging prospective ultrasound allows as an operator dependent modality; therefore, each image contains an adjacent schematic display of the orientation and placem...
Brain Imaging
is an installment of the Dx-Direct: Direct Diagnosis in Radiology series published by Thieme. This book limits its scope to imaging of the brain. Spine and head/neck imaging are covered in other texts, along with the other major radiologic subspecialties. (Source: Academic Radiology)
Rich Corporate Types
For several decades, my mailbox has been cluttered each year with annual reports and proxy statements from companies in which I own shares. The annual report, with its glowing color photos, tells me just how wonderful the company did in the past year. The introductory essay from the chief executive relates how wonderful things will be next year. But the financial summary may be contradictory to management's self-praise. More of that may be confirmed if I wade deeply into the fine print in the back part of the report. The other part of the package, which many of us share, is a folder and statement soliciting proxy votes for positions taken by the corporate board. Any resemblance between the board's action and the optimistic annual report may be hard to find. (Source: Academic Radiology)
Thresholds to Lung Density Measures
This article highlights an important topic for emphysema measurement. However, in their paper, the authors state, “Based on pathology comparisons…and literature-based consensus…−910 HU [Hounsfield units] was specified a priori as the threshold for primary analyses.” A threshold of −910 HU was established by Müller et al , who used one single-slice computed tomographic scan with a slice thickness of 10 mm and intravenous contrast. Slice thickness and the use of intravenous contrast influence lung density and the measurement of emphysema . Recently, Madani et al reported a study using multidetector computed tomography without iodinated contrast. The strongest correlation of multidetector computed tomography with macroscopy was observed at a threshold of −970 HU (r = 0.543, P <...
Drs Hoffman and Barr Replies:
We would like to thank Drs. Hochhegger, Irion and Marchiori for their kind comments and their thoughtful questions. The issue regarding appropriate density-mask thresholds for the characterization of emphysema via quantitative computed tomography (CT)-based assessment of the lung is an important one. Quantitative CT has been used with increasing frequency to assess presence, extent, and location of emphysema-like lung for the purposes of pharmaceutical efficacy testing, safety testing, population selection for device placement, and for the identification of homogeneous subphenotypes within the chronic obstructive pulmonary disease (COPD) population to better target new therapeutic development efforts. Although quantitative CT has contributed greatly to these efforts, the measures are, in ...

Comparison of Conventional Abdominal CT with MR-Enterography in Patients with Active Crohn's Disease and Acute Abdominal Pain
Conclusions: In patients with known advanced CD with acute abdominal pain conventional abdominal MD-CT, which is frequently performed as an emergency imaging procedure, is sufficient for bowel wall assessment. Based on our data, additional dedicated small bowel imaging such as MRE seems not to be necessary. (Source: Academic Radiology)
Volumetric Analysis of Pulmonary CTA for the Assessment of Right Ventricular Dysfunction in Patients with Acute Pulmonary Embolism
Conclusion: Ventricle volumetry of non–ECG-gated CTA allows the assessment of right ventricular dysfunction in patients with acute PE. Compared to unidimensional measurements, a volumetric analysis seems to be slightly superior to identify high-risk patients with adverse clinical outcome. However, the method is more time consuming and requires dedicated software tools compared to unidimensional parameters, which is disadvantageous in an emergency setting. (Source: Academic Radiology)
Computer-Aided Diagnosis of Lung Nodules on CT Scans: ROC Study of Its Effect on Radiologists' Performance
Conclusion: CAD has the potential to increase radiologists' accuracy in assessing the likelihood of malignancy of lung nodules on CT imaging. (Source: Academic Radiology)
