    An intense F-FDG pulmonary microfocus on PET without detectable abnormality on CT: A manifestation of an iatrogenic FDG pulmonary embolus.
    Biomed Imaging Interv J 2010 Oct-Dec;6(4):e37. Epub 2010 Oct 1.
    Nuclear Imaging Centre, Faculty of Medicine, University Putra Malaysia.
    An incidental finding of an intense focus of (18)F-Fluorodeoxyglucose (FDG) pulmonary uptake on positron emission tomography (PET) without detectable lesions on computed tomography (CT) is highly suggestive of FDG microembolus. Its microscopic nature means it is undetectable on CT. It is an artefact attributable to (18)F-FDG-tracer contamination at the injection site. Read More

    Significance of subcentimetre F-FDG PET/CT pulmonary abnormality in patients with known extrapulmonary malignancy.
    Biomed Imaging Interv J 2010 Oct-Dec;6(4):e34. Epub 2010 Oct 1.
    Centre for Diagnostic Nuclear Imaging , Faculty of Medicine and Health Science, Universiti Putra Malaysia, Malaysia.
    The significance of a subcentimetre (18)F-FDG PET/CT pulmonary abnormality in a patient with known extrapulmonary primary malignancy can have a major impact on the clinical management of the patient. The clinician's reliance on the semi-quantitative and qualitative PET/CT analysis of the abnormality has, at times, led to untoward diagnostic problems, given the limited spatial resolution of PET for a small volume lesion performed as part of the standard PET/CT study. This paper highlights a case each of an FDG-positive and an FDG-negative focal pulmonary abnormality in a combined PET/CT study of patients with known extrapulmonary malignancy. Read More
