There are numerous procedures where the imaging component is considered a supplemental or secondary technique to help accomplish the primary goal. The pattern is:

Procedure using guidance

• FSN: Y using <diagnostic imaging modality> guidance (procedure)
• PT:  <Diagnostic imaging modality> guided Y
• SYN: Y using <diagnostic imaging modality> guidance

Computed tomography guided procedure

• FSN: Y using computed tomography guidance (procedure) 
• PT:  CT guided Y
• SYN: Y using computed tomography guidance

For example,

• • 
    • FSN:  Injection using computed tomography guidance (procedure)
    • PT:  CT guided injection
    • SYN:  Injection using computed tomography guidance

Fluoroscopy guided procedure

• FSN: Y using fluoroscopic guidance (procedure) 
• PT:  Fluoroscopy guided Y
• SYN: Y using fluoroscopic guidance

For example, 

• • 
    • FSN:  Biopsy of abdomen using fluoroscopic guidance (procedure)
    • PT:  Fluoroscopy guided biopsy of abdomen
    • SYN:  Biopsy of abdomen using fluoroscopic guidance

The term fluoroscopic Y is interpreted as Y using fluoroscopic guidance (procedure).  Procedures such as are subtypes of Fluoroscopy (procedure).

Magnetic resonance imaging guided procedure

• FSN:  Y using magnetic resonance imaging guidance (procedure) 
• PT:  MRI guided Y
• SYN:  Y using magnetic resonance imaging guidance

For example, 

• • 
    • FSN:  Core needle biopsy of breast using magnetic resonance imaging guidance (procedure)
    • PT:  MRI guided core needle biopsy of breast
    • SYN:  Core needle biopsy of breast using magnetic resonance imaging guidance

Ultrasonography guided procedure

• FSN:  Y using ultrasonographic guidance (procedure) 
• PT:  Ultrasonography guided Y
• SYN:  Y using ultrasonographic guidance
• SYN:  Y using ultrasound guidance

For example, 

• • 
    • FSN:  Biopsy of wrist using ultrasonographic guidance (procedure)
    • PT:  Ultrasonography guided biopsy of wrist
    • SYN:  Biopsy of wrist using ultrasonographic guidance
    • SYN:  Biopsy of wrist using ultrasound guidance

Plain X-ray guided procedure

• FSN:  Y using plain X-ray guidance (procedure) 
• PT:  Plain X-ray guided Y
• SYN:  Y using plain X-ray guidance

For example, 

• • 
    • FSN:  Injection of steroid using plain X-ray guidance (procedure)
    • PT:  Plain X-ray guided steroid injection
    • SYN:  Injection of steroid using plain X-ray guidance
