SPECT/CT arthrography

Area of Science:

• Radiology
• Nuclear Medicine
• Orthopedics

Background:

• Single photon emission CT (SPECT)/CT arthrography, developed in 2011, integrates CT arthrography with late-phase bone SPECT/CT.
• This hybrid imaging modality provides both functional (bone turnover) and morphological information.

Purpose of the Study:

• To review and report a 5-year experience with SPECT/CT arthrography.
• To highlight its utility in evaluating internal derangements of the knee, ankle, and wrist joints.
• To present SPECT/CT arthrography as an alternative for patients with MR contraindications or metallic implants.

Main Methods:

• Combination of CT arthrography and late-phase bone SPECT/CT.
• Intra-articular contrast administration for enhanced visualization of intra-articular structures.
• Review of patient cases over a 5-year period.

Main Results:

• SPECT/CT arthrography enables assessment of cartilage, menisci, ligaments, and loose bodies.
• The technique provides functional insights into bone turnover alongside detailed anatomical imaging.
• Demonstrated utility in evaluating complex joint pathologies.

Conclusions:

• SPECT/CT arthrography is a valuable tool for assessing internal joint derangements.
• It offers a promising alternative to MRI in specific patient populations.
• Future applications of this technique are anticipated.
