Summary
Bone SPECT imaging of the feet using a new fan-beam collimator accurately localizes abnormalities. This technique aids in diagnosing skeletal pathology in the foot and ankle, outperforming planar radiology.
Area of Science:
- Nuclear Medicine
- Radiology
- Skeletal Imaging
Background:
- Assessing the diagnostic utility of bone SPECT in foot imaging.
- Utilizing a novel uniplanar fan-beam collimator, originally designed for cardiac imaging.
Purpose of the Study:
- To evaluate the effectiveness of bone SPECT with a new collimator for foot imaging.
- To determine if this technique can accurately localize skeletal pathology in the foot and ankle.
Main Methods:
- 18 patients with suspected foot/ankle pathology underwent SPECT imaging with a dual-headed gamma camera and uniplanar fan-beam collimators.
- 99mTc MDP was administered, and SPECT data was acquired in a 128x128 matrix.
- Images were reconstructed into transaxial, coronal, sagittal, and 3D volume-rendered formats for blinded review.
Main Results:
- SPECT images were of good quality, with sagittal and 3D views aiding localization.
- Abnormalities explaining symptoms were found in 10 patients.
- Planar radiology was unhelpful in 13 out of 17 patients.
Conclusions:
- SPECT imaging of the feet is feasible and effective using uniplanar fan-beam collimators.
- This method provides accurate localization of abnormal uptake.
- Standard acquisition time is 15 minutes with a dual-headed gamma camera.
