A plain CT scan
of the chest will miss lung clots unless very obvious.
A /Q scan is a better test to pick up lung clots and suggest you immediately get a consult if you continue to feel unwell.
If you had recently been on a long haul flight or travel, recent surgery or immobilisation, your risks are higher. An ECG is also helpful at times.
Please check in at your nearest ER or A&E (Emergency) today.
