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: 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),...

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...

Aim: Assess the role of hybrid modality SPECT/CT versus planar scintigraphy in sentinel lymph node (SLN) identification patients with breast cancer. Methods: Planar and were performed 23 women cancer (mean age 59.5 years range 25 - 82 years) invasive (T0, T1 T2), without clinical evidence axillary metastases (N0) no remote (M0), radiocolloid was injected four subareolar sites. images separately...

Background: Hairline rib fracture commonly happens after blunt trauma, and it is hard to be detected by X-ray. Many methods can used, among them, the hybrid image of single-photon emission computed tomography (SPECT) (CT) seems produce higher sensitivity for diagnosis. Case presentation: A 63-year-old man came our rehabilitation clinic a vehicle accident 25 days earlier. He had multiple plain f...

The increasing evidence of oncocytic renal tumors positive in 99mTc Sestamibi Single Photon Emission Tomography/Computed Tomography (SPECT/CT) examination calls for the development diagnostic tools to differentiate these from more aggressive forms. This study combined radiomics analysis with uptake on SPECT/CT benign neoplasms cell carcinoma. A total 57 were prospectively collected. Histopathol...

we report a three-phase bone scintigraphy for the diagnosis of a peripheral bone lesion caused by systemic sarcoidosis. a 32-year-old man with suspected osteomyelitis of the right forefinger underwent three-phase bone scintigraphy with tc-99m hydroxymethylene diphosphonate (hmdp) and single-photon emission computed tomography/computed tomography (spect/ct). the lesion was rich in blood flow acc...

Objective(s): 99mTc-PSMA SPECT/CT is a cost effective alternative for 68Ga-PSMA PET/CT. The aim of this study was to directly compare these two techniques in patients with prostate cancer. Methods: 28 man with prostate cancer were studied using 99mTc-PSMA SPECT/CT and 68Ga-PSMA PET/CT in a shor...

Objective: The aim of this study was to evaluate the influences of reconstruction and attenuation correction on the differences in the radioactivity distributions in 123I brain SPECT obtained by the hybrid SPECT/CT device. Methods: We used the 3-dimensional (3D) brain phantom, which imitates the precise structure of gray mater, white matter and bone regions. It was filled with 123I solution (20...
