background subdiaphragmatic activity can produce subdiaphragmatic-related artifacts, which can degrade the quality of myocardial perfusion imaging (mpi). objectives we examined the impact of drinking milk, water, and lemon juice on different subdiaphragmatic-related artifacts by using 99mtc-sestamibi myocardial single-photon emission computed tomography (spect) in order to determine a feasible ...

objective(s): in this study, we aimed to evaluate the efficacy of thyroid volume measurement using 99mtc pertechnetate single-photon emission computed tomography (spect) images, acquired by the standardized uptake value (suv)-shape scheme designed by our expert team.methods: a total of 18 consecutive patients with graves’ disease (gd) were subjected to both ultrasonographic and 99mtc pertechnet...

background: the implications of cardiac risk stratification before orthotopic liver transplantation (olt) are not well established. we studied the usefulness of myocardial perfusion imaging (mpi) in this scenario. methods: mpi data of 24 patients (9 females), candidates of olt, were collected. they underwent mpi as part of their preoperative risk assessment. mpis were interpreted by 2 nuclear p...

a 22-year-old woman presented with acute left-sided pleuritic chest pain and dyspnea 6 days after surgery for revision of the stenotic central aortopulmonary shunt. she had a history of tetralogy of fallot (tof), pulmonary valve stenosis, ventricular septal defect and major aortopulmonary collateral artery. her waterston shunt was placed when she was 5 years old and stented and re-dilated after...

This mage based series comprises of a quiz pertaining to the identification of salient anatomical structures expected to be seen at a given level on the computed tomography (CT) followed by examples of multiple representative pathologies that can be seen at the same level in a routine clinical setting. It is expected that this will improve confidence of nuclear physicians in interpretation of t...

anosmia following head trauma is relatively common and in many cases is persistent and irreversible. the ability to objectively measure such a decline in smelling, for both clinical and medicolegal goals, is very important. the aim of this study was to find results of brain single photon emission computed tomography (spect) in anosmic subjects after closed head trauma. this case-control cross s...

solitary pulmonary nodule (spn) is a frequent finding on the chest x-ray and computed tomography. nuclear medicine techniques play an important role in the diagnosis and management of spn. in the current review, we briefly will explain the different nuclear medicine modalities in this regard including positron emission tomography (pet) using 18-f-fdg, and 11-c-methionine, and single photon emis...

In this series a pictorial quiz pertaining to identification of normal anatomical structures and landmarks at a given level on the computed tomography (CT) is presented. An image depicting normal anatomy is followed by a series of images showing different pathologies. Readers are expected to identify and appreciate variation and changes in the normal anatomy in presence of a given pathology. Th...
