Presentation
2 day history of shortness of breath and dry cough.
Patient Data
Maximum intensity projection (MIP) images demonstrate normal homogenous perfusion throughout the lungs with no perfusion defect.
SPECT axial images demonstrated normal homogenous perfusion throughout the lungs with no perfusion defect.
Fused SPECT-CT images of the thorax. The perfusion images have been superimposed onto a non-contrast CT chest, acquired immediately following the perfusion study.
Case Discussion
During the COVID pandemic, the ventilation portion of a VQ scan was often not performed as it was deemed an aerosol generating procedure and therefore a potential risk to the nuclear medicine staff.
The CT chest, as in this example, was utilized as a surrogate for the ventilation portion of the study.
