Background & Objective: This study aimed to investigate the effect of decellularized allogeneic bone graft enriched by periosteal stem cells (PSCs) and growth factors on the bone repair process in a rabbit model, which could be used in many orthopedic procedures. Methods: In this experimental study, a critical size defect (CSD) (10 mm) was created in the ...
background diagnosis and accuracy in determining the exact location, extent and configuration of bony defects of the jaw are of utmost importance to determine prognosis, treatment planning and long-term preservation of teeth. if relatively accurate diagnosis can be established by radiography, proper treatment planning prior to treatment procedures will be possible. objectives the aim of the pre...
Objective(s): This study was designed to assess defect detectability in positron emission tomography (PET) imaging of abdominal lesions. Methods: A National Electrical Manufactures Association International Electrotechnical Commission phantom was used. The simulated abdominal lesion was scanned for 10 min using dynamic list-mode acquisition method. Images, acquired with scan duration of 1-10 mi...
Background: Butterworth, Gaussian, Hamming, Hanning, and Parzen are commonly used SPECT filters during filtered back-projection (FBP) reconstruction, which greatly affect the quality and size accuracy of image. Materials and Methods: This study involved a cardiac phantom in which 1.10 cm thick cold defect was inserted into its myocardium wall and filled with 4.0 μCi/ml (0.148 MBq/ml) 99mTc conc...
one of the complications of twinning of mono chorionic mono amniotic gestations is conjointed twins. structural congenital malformations occur in 5 % to 7 % of twin gestations versus only 3 % of singleton births. most defects occurring in only one of the twin fetuses. occasional anomalies such as omphalocele sincenomalia heart defect one reported in both concordance. the structural defect commo...
