Procedure Overview
Plain radiography of the upper arteries captures a static image using external x-ray exposure onto film or a digital detector, producing a flat picture of bone, soft tissue density, and, when contrast is present, the vessel outline. On its own, without contrast, a plain film shows little about the arteries directly, since blood vessels are not naturally distinct from surrounding tissue on x-ray, so this family is most often applied where calcification within an artery wall, a foreign body, or an implanted device such as a stent is visible.
Because it is a single static exposure rather than a moving or contrast-enhanced study, plain radiography of the arteries is used less for primary vascular diagnosis and more to confirm findings incidental to arterial disease, such as vascular calcification patterns or the position of hardware near the upper extremity vessels.
Anatomy & Axis Detail
Upper Extremity Arteries, Right
The right upper extremity arterial tree, extending from the subclavian artery through the axillary, brachial, and forearm vessels into the hand, is imaged with contrast to evaluate the vascular supply of the entire limb in a single study. Indications include suspected embolic or thrombotic occlusion, trauma with vascular injury, vasculitis such as Buerger disease or thoracic outlet–related compression, and preoperative planning for dialysis access or bypass grafting. Because the right subclavian artery originates from the brachiocephalic trunk rather than directly from the aorta, its proximal anatomy differs from the left, which can be relevant when comparing findings between sides. Imaging the full extremity allows the radiologist to trace a single lesion's downstream effects on collateral circulation and distal perfusion, rather than assessing an isolated segment in isolation.
Coding & Documentation
Coders assign from this family only when the radiology report describes a conventional radiographic exposure of the upper arterial vessels rather than a fluoroscopic or angiographic technique, since the terms are sometimes used loosely by clinicians in dictation. The body part selected must match the specific artery or arterial region named, such as the subclavian, axillary, or brachial artery, rather than defaulting to a general upper extremity code. A common mistake is coding a fluoroscopically guided arteriogram under plain radiography because the order was mislabeled, when the presence of contrast injection and real-time imaging in the note points instead to the fluoroscopy family.
Commonly Confused With
This family is easily confused with fluoroscopy of the upper arteries, which is the modality actually used for most diagnostic arteriograms because it captures contrast moving through the vessel in real time; a plain film cannot show flow. It is also distinct from CT of the upper arteries, which reconstructs cross-sectional and three-dimensional vascular anatomy from many exposures rather than producing a single flat image, and the report's description of a single static exposure versus a series or reconstruction is what separates the two.
