CT question

By

The question :

An enhanced CT scan of an adult head shows an irregular shaped low-density mass with extensive vasgoenic edema. Which type of tumor is this likely to be?

A. MENINGIOMA B. GLIOBLASTOMA C. METS D. ASTROCYTOMA

so I've narrowed it down to for sure not being A (no vasogenic edema with meningiomas), or C (bc contrast will be homogenous enhancment).

Glioblastomas, according to my manual, has vasogenic edema, is multi lobulated with areas of central necrosis. With contrast, it displays heterogenous, irregular ring enhancement of lesion.

Astrocytomas have little to no enhancement. However, high grade forms appear heterogenous, enhance with contrast and have vasogenic edema and mass effect.

Am I reading too much into it ? I'm so confused.

AI for radiology - A survey

By
Hello folks! We are a group of students from Karolinska Institutet and Stockholm University (Sweden). We are conducting a short survey (it should not take more than 10 minutes of your time) to evaluate an Artificial Intelligence framework for evaluating medical imaging and, in particular, the effect that explainability can have on clinicians' attitudes toward it. We welcome anyone who interacts with medical imaging to take our survey, so please, feel free to do it even if you are still a student or an intern! If you know someone who works in the field, please, pass them the survey. It would help us greatly. https://bit.ly/RTEX_survey Thanks in advance to all of you! submitted by /u/francozzz [link] [comments] source https://www.reddit.com/r/Radiology/comments/r2ratp/ai_for_radiology_a_survey/
