OBJECTIVE Single photon emission computed tomography (SPECT) images provide many details of the anatomical structure. Also about bone scintigraphy, there are many reports of the improvement of diagnosis by SPECT images. Although SPECT is useful, it requires much time. So to perform SPECT for all cases is difficult in the clinical situation. Recently, due to technical improvements in gamma camer...

this study was performed to evaluate the tc-pyp spect role in determination of ami severity and extension. pyp spect imaging was done for 54 patients with ami, who met the who criteria. spect findings were correlated with lvef measurements. the abnormal scan was graded according to the intensity and was compared with the activity of the sternum in the same image. in addition, a segmental myocar...

Introduction: Nuclear medicine (NM) can provide unique information about sentinel lymph nodes, although it shows poor anatomical information; therefore, the superimposition of NM images on MR images would enhance the excellent features of MRI in spatial resolution and tissue contrast. A high magnetic field, however, makes it difficult to develop a combined scanner, especially in combination wit...

post stroke dementia is one of the most common complications of stroke that is preventable and relatively treatable too. the purpose of the study is comparison between the positive findings in brain ct scan and brain perfusion spect. 15 patients who were complicated by dementia after cerebrovascular accident and also 5 patients as a control group enrolled in this study. brain ct scan and brain ...

Introduction: Nuclear medicine (NM) can provide unique information about the distribution of receptors or sentinel lymph nodes (SLNs), although it shows poor anatomical information; therefore, the superimposition of NM images on MR images would enhance the excellent features of MRI in spatial resolution and tissue contrast. A high magnetic field, however, makes it difficult to develop a combine...

OBJECTIVES This study assessed the incremental value of technetium-99m myocardial single-photon emission computed tomography (SPECT) and simultaneous first-pass radionuclide angiography, when added to treadmill exercise, for prediction of the extent of coronary artery disease. BACKGROUND Technetium-99m count statistics permit the simultaneous assessment of myocardial perfusion and function. H...

BACKGROUND AND PURPOSE Diagnostic performance by MR imaging or by SPECT alone in discriminating DLB patients from AD patients has been estimated previously. However, the performance of a combination of MR imaging and SPECT has not yet been evaluated. Our aim was to evaluate the usefulness of combining MR imaging and SPECT to discriminate mild DLB from AD. MATERIALS AND METHODS Nineteen patien...

BACKGROUND Controversy exists regarding the superiority of single photon emission CT (SPECT)/CT over SPECT for preoperative localization of parathyroid adenomas in primary hyperparathyroidism (PHPT), as well as the cost-effectiveness. METHODS A retrospective review was undertaken of patients undergoing surgery for PHPT from January 2009 to August 2014. Ultrasound and SPECT (ultrasound-SPECT) ...

UNLABELLED The present study evaluated the role of SPECT/CT as an adjunct to (67)Ga (GS) or (111)In-labeled white blood cell (WBC) scintigraphy for diagnosis or localization of infection. METHODS Eighty-two patients (56 male and 26 female; mean age, 62 y) assessed for known or suspected infectious processes underwent 88 SPECT/CT studies. Forty-seven patients underwent GS SPECT/CT (13 with fev...

OBJECTIVE The objective was to quantify the potential economic value of single-photon emission computed tomography (SPECT) with computed tomography (CT; SPECT/CT) versus CT pulmonary angiography (CTPA), ventilation-perfusion (V/Q) planar scintigraphy, and V/Q SPECT imaging modalities for diagnosing suspected pulmonary embolism (PE) patients in an emergency setting. METHODS An Excel-based simu...
