PURPOSE The purpose of this study was to compare the diagnostic performance of SPECT/CT and MRI in patients with ankle and foot pain, with regard to the lesion types. MATERIALS AND METHODS Fifty consecutive patients with ankle and foot pain, who underwent 99mTc-MDP SPECT/CT and MRI, were retrospectively enrolled in this study. Symptomatic lesions were determined based on clinical examination ...

  Introduction: Although PET scanning using F-18[FDG] is considered the superior radiotracer for tumnor imaging, Gallium-67 is still in use for some malignancies such as lymphoma and hepatoma. One of the strategies to improve the diagnostic accuracy of Gallium is to perform SPECT which is reported to be more sensitive compared to planar imaging. In this study we compa...

Introduction: Many patients have only diastolic dysfunction without any abnormality in systolic function. We compared cardiac diastolic parameters obtained by gated myocardial perfusion SPECT (Gated SPECT) with those evaluated by echocardiography. Methods: Forty-nine patients (aged 37-85 years, 19 males and 30 women) underwent Gated SPECT and echocardiogr...

Introduction: The main purpose of this study was to compare transient ischemic dilation (TID) ratios in SPECT-low dose CT and SPECT Myocardial Perfusion Imaging (MPI) by application of different quantitative programs and quantify the possible shift in the upper normal limits of TID ratio in the SPECT-CT MPI. Methods: 149 Patients with low pre-test probability for coronary artery disease (CAD),...

Whether a patient with head and neck cancer has mandibular invasion or not is important in determining the method of resection surgery. But, no modality is adequately reliable when used alone in the evaluation of mandibular invasion. Therefore, to more accurately diagnose mandibular invasion in head and neck cancer, we used a new modality, namely, 99mTc methylene diphosphonate (MDP) or 99mTc hy...

introduction: hemangiomas are the most frequent benign tumors of the liver and detecting them from metastasis or other malignant hepatic tumors is of outmost importance. 99mtc- rbc scan is highly specific and is the method of choice for this differentiation. this scintigraphy is performed in planar and spect modes. these two procedures are in agreement most of the times, however since spect is ...

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...

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 ...

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...
