UNLABELLED Does subtraction scintigraphy improve the diagnostic utility of scintigraphic evaluation in acute lower gastrointestinal hemorrhage? METHODS This research was a retrospective clinical study using a repeat-measures design of randomized control and experimental groups. A single patient dataset provided both the control group (conventional scintigraphy) and the experimental group (con...

BACKGROUND Thyroid imaging with isotopic iodide (123I) or technetium Tc 99m pertechnetate has been available for decades but is not routinely used in newborn infants diagnosed with congenital hypothyroidism (CH). Among clinicians who believe that presence, absence, or abnormal location of a thyroid does not alter management of CH, imaging is not advocated for anatomic diagnosis of CH. OBJECTI...

BACKGROUND Neuroblastoma is an embryonic tumour of childhood that originates in the neural crest. It is the second most common extracranial malignant solid tumour of childhood.Neuroblastoma cells have the unique capacity to accumulate Iodine-123-metaiodobenzylguanidine (¹²³I-MIBG), which can be used for imaging the tumour. Moreover, ¹²³I-MIBG scintigraphy is not only important for the diagnosis...

PURPOSE We aimed to assess the role of single photon emission computed tomography-computed tomography (SPECT-CT) for characterizing isolated vertebral lesions observed by bone scintigraphy compared to planar scintigraphy, SPECT, and CT, and to evaluate the impact of SPECT-CT on patient management. MATERIALS AND METHODS Data from 99 patients (mean age, 52.4±18.9 years; females, 58.5%) with 108...

introduction: this study was launched to evaluate the sensitivity and specificity of 99mtc-ciprofloxacin to distinguish infection foci induced by staphylococcus aureus and inflammation lesions induced by carrageenan in the rat foot in comparison with 67ga-citrate scintigraphy. methods: the labeling and quality control of 99mtc-ciprofloxacin kits have been performed according to the manufacture...
