Yes, that is true. A CT can be better but not necessarily. It has to be done with angiography in mind. Bear in mind that conventional angiography requires that a catheter be placed into the artery or veir in order for the "dye" (really an iodinated contrast agent) to visualize the vessels in question. The angiography is ofetn done (at least in my practice after a CTA (CT angiogram) or MRA (MR Angiogram ) in order to treat an underlying problem ie angioplasty or stent.

Correct!
Digital subtraction angiography is what I see most in the OR - they take an xray, then shoot radiopaque dye in the vessel they want to examine, and shoot another xray.
The machine then removes the first xray image from the second xray, so only the dye shows.
Angiography shows the interior of the blood vessels, and can be done pretty much anywhere in the body (as long as someone can feed a catheter into the artery). It's commonly done for brain, heart, and extremity vessels.

A ct scan whould be better to see blood vessels because x-rays are great for looking at the bones.
