Bony Anatomy in Radiology

00:01 So let's take a look at the bony structures that can be evaluated on a radiograph.

00:06 You can see here both clavicles.

00:08 We often see clavicular fractures occur and sometimes their incidental findings.

00:13 So it's important to take a look at all of the bones carefully.

00:16 You can see the outline of the scapula which comes around to this way and projects posterior to a portion of the lung.

00:25 You can see liver in the upper abdomen and you really shouldn't see any pocket of air in this area.

00:34 Every once in a while you may see a little pocket of colon that can come up this way.

00:39 For the most part though, it really should just be in a soft tissue density, and if you do see air that's concerning for free air in the abdomen.

00:46 You can see the spinous processes as we saw earlier and they really should be midline within the trachea.

00:53 And then you should see air in the left upper abdomen and that usually represents stomach and possibly colon.

01:00 On the lateral view, you can have a good image of the thoracic spine, and this is a good view to take a look at for any kind of thoracic compression abnormalities or bony abnormalities.

01:13 So in this lecture, we've gone over multiple different radiographic projections of the chest, they include the PA, the lateral, as well as the AP, and decubitus.

01:25 We've also gone over different positions and how they change the appearance of the chest radiograph.

01:29 And we've gone over different types of techniques which you can also change the appearance of a radiograph.

01:34 We've also come up with a good algorithm and you should use this algorithm as you look at all the different chest x-rays that we'll be evaluating in these future talks.
