Methods and Materials
We analysed consecutive SPECT/CT wrist studies performed in cases
with a documented history of trauma between September 2007 and
January 2017.
Protocol
- 800MBq (22 mCi) of 99mTcMDP
- Early blood pool and 3hr delayed static views of wrists were acquired
- SPECT/CT of wrist were performed after review of delayed images.
Patient Positioning
- Superman position
- Hand is covered by a mesh
A 16-slice Philips Precedence® SPECT/CT camera and local protocol
Technetium 99m doses were utilised.
In addition,
dose adjusted CT
acquisition allowed us to produce diagnostic studies in line with ALARP
(as low as reasonably practicable) principles.
Blood pool,
delayed static
and SPECT/CT of the wrists with whole body planar imaging were
acquired.
SPECT/CT results were obtained using a departmental database and
correlated with electronic patient records.
Data collected included
demographics,
indications for imaging,
previous interventions and
imaging,
dose saving results and the referral pathway.
Studies were dual reported by specialist Nuclear Medicine and
Musculoskeletal consultant radiologists.
Findings were then correlated with recorded clinical outcomes; consisting of up to 10 years follow up.
The evaluation was performed for
- Anatomical localisation
- Clinical question answered
- Characterisation
- Final diagnosis
- Change in management
