OBJECTIVES We sought to determine whether taking oral erythromycin prior to SPECT myocardial perfusion imaging with Tc99m-sestamibi would reduce the amount of interfering extra-cardiac activity and improve the image quality. METHODS A total of 96 patients who were routinely referred for myocardial perfusion imaging were randomly assigned to one of two(More)
Prostate-specific membrane antigen (PSMA), a type II glycoprotein, is highly expressed in almost all prostate cancers. By playing such a universal role in the disease, PSMA provides a target for diagnostic imaging of prostate cancer using positron emission tomography/computed tomography (PET/CT). The PSMA-targeting ligand Glu-NH-CO-NH-Lys-(Ahx)-HBED-CC(More)
Introduction: A 37-year-old man was referred for PET/CT with the following diagnostic challenge: a longstanding smoking history, histologically confirmed TB and sarcoidosis with worsening chest-related symptoms and a non-responsive right upper lobe lung lesion (as detected on CT). Materials and Methods: PET/CT imaging was performed with 18 F-FDG and(More)
BACKGROUND To report on imaging findings using 68Ga-PSMA-HBED-CC PET in a series of 19 breast carcinoma patients. METHODS 68Ga-PSMA-HBED-CC PET imaging results obtained were compared to routinely performed staging examinations and analyzed as to lesion location and progesterone receptor status. RESULTS Out of 81 tumor lesions identified, 84% were(More)
Single-photon emission computed tomography-computed tomography (SPECT-CT) allows for physiological and anatomical co-registration in sentinel lymph node (SLN) mapping and offers additional benefits over conventional planar imaging. However, the clinical relevance when considering added costs and radiation burden of these reported benefits remains somewhat(More)
Introduction: Spinal tuberculosis is a serious health care problem and diagnosis is often difficult because many diseases may have similar imaging findings. Hence the need to describe findings of spinal tuberculosis with 2-[fluorine 18]fluoro-2-deoxy-D-glucose (FDG) positron emission tomography (PET) when compared to CT. Materials and Methods: Sixteen(More)
Bladder artifact during bone single-photon emission computed tomography (SPECT) is a common source of error. The extent and severity of bladder artifacts have been described for filtered back projection (FBP) reconstruction. Ordered subset expectation maximization (OSEM) may help to address this problem of bladder artifacts, which render up to 20% of the(More)
