Is there a section for radiology?

You can use the "Lab/Diagnostic Test" category to categorize an entry as a CT scan, X-ray, MRI, or ultrasound. Then, use #rad to file it under radiology. Here's how:

First, tap the "New Entry" button.

Add any images using the camera button. 

After adding the images, write down a description including the type of test. Use the tag button to categorize as Lab/Diagnostic test. 

Then, tap the # button and select "#rad" to file as a radiology report. 

You can find all your radiology reports by tapping "#rad" under the search bar in the Timeline view.
