The veins are much larger than the artery at the same level, and also the arteries are deeper.

If you remember ur anatomy and orient urself to the particular level of the image; know what lies lateral, medial, deep, superficial etc based on landmarks, then it should be easy.

What veins and arteries are u talking about?

Whenever there is a question about ivc filter or "where this abnominal aneurism is originated from?" there is only one CT image at the same level, over and over again.

The only problem u face here is to distinguish between Inferior Vena Cava and Portal vein. U just need to memorize what is what after looking once on netters picture.

All the rest is not really about distinguishing between color, size or something on a CT - its about knowing VAN and NAVEL mnemonics I think
