Fluoroscopy and Fluoroscopic Imaging
Simple fluoroscopy
Simple fluoroscopy is real time imaging (usually on TV monitors/image intensifiers) of a body part or system. Only rarely is it an imaging process alone (without some interventional procedure). Fluoroscopy is most often used to guide or direct a primary procedure/purpose. The usual convention in clinical practice is to ignore the fluoroscopic element and refer to a procedure entirely by the primary component, e.g., angiography. However, this is unacceptable in SNOMED CT, where the imaging component must be explicitly described.
FSN: Fluoroscopy of X (procedure)
PT: Fluoroscopy of X
SYN: Fluoroscopy - X
For example,
169005008 | Fluoroscopy of esophagus (procedure)
FSN: Fluoroscopy of esophagus (procedure)
PT: Fluoroscopy of esophagus
SYN: Fluoroscopy - esophagus
Fluoroscopic guidance
Fluoroscopic X is not necessarily interpreted as X using fluoroscopic guidance (procedure). When modeling a procedure using fluoroscopic guidance, the use of fluoroscopic x in the FSN is not sufficient; the FSN must explicitly state using fluoroscopic guidance if that is the intent.
The following naming pattern can be used for direct observation:
FSN: X using fluoroscopic guidance (procedure)
PT: Fluoroscopy guided X
SYN: X using fluoroscopic guidance
For example,
710293001 | Colonoscopy using fluoroscopic guidance (procedure)
FSN: Colonoscopy using fluoroscopic guidance (procedure)
PT: Fluoroscopy guided colonoscopy
SYN: Colonoscopy using fluoroscopic guidance
For example,
Angioplasty using fluoroscopic guidance with contrast (procedure)
FSN: Angioplasty using fluoroscopic guidance with contrast (procedure)
PT: Fluoroscopy guided angioplasty with contrast
SYN: Angioplasty using fluoroscopic guidance with contrast
SYN: Fluoroscopic angioplasty with contrast
Such procedures are subtypes of Fluoroscopy (procedure). See also Imaging-guided procedure modeling.
Fluoroscopic angiography with contrast
Angiography and angiogram , as terms on their own, refer to visualization of a blood vessel or vascular structure not specified as an artery or a vein and could refer to either or both. So for clarity, a blood vessel site (X) and the phrase with contrast must be included in the concept description.
With contrast
Fluoroscopic angiography always uses contrast. With contrast must be explicitly stated in all descriptions.
Fluoroscopic angiography when vessel is not stated
FSN: Fluoroscopic angiography of X with contrast (procedure)
PT: Fluoroscopic angiography of X with contrast
SYN: Fluoroscopic angiogram of X with contrast
Fluoroscopic angiography of artery
FSN: Fluoroscopic angiography of X artery with contrast (procedure)
PT: Fluoroscopic angiography of X artery with contrast
SYN: Fluoroscopic arteriography of X with contrast
SYN: Fluoroscopic arteriogram of X with contrast
For example,
FSN: Fluoroscopic angiography of right cervical vertebral artery with contrast (procedure)
PT: Fluoroscopic angiography of right cervical vertebral artery with contrast
SYN: Fluoroscopic arteriography of right cervical vertebral artery with contrast
SYN: Fluoroscopic arteriogram of right cervical vertebral artery with contrast
Fluoroscopic venography
FSN: Fluoroscopic venography of X with contrast (procedure)
PT: Fluoroscopic venography of X with contrast
SYN: Fluoroscopic venogram of X with contrast
For example,
FSN: Fluoroscopic venography of right upper limb with contrast (procedure)
PT: Fluoroscopic venography of right upper limb with contrast
SYN: Fluoroscopic venogram of right upper limb with contrast
Fluoroscopic arthrography
FSN: Fluoroscopic arthrography of X (procedure)
PT: Fluoroscopic arthrography of X
SYN: Fluoroscopic arthrogram of X
For example,
723775001 | Fluoroscopic arthrography of right sacroiliac joint (procedure)|
FSN: Fluoroscopic arthrography of right sacroiliac joint (procedure)
PT: Fluoroscopic arthrography of right sacroiliac joint
SYN: Fluoroscopic arthrogram of right sacroiliac joint
