Effect of Span and MRD Configurations on Small Animal PET Image Quality and Quantitative Accuracy.

Background: Employing 2D rebinned sinograms in PET scanners has the potential to accelerate the overall reconstruction speed. Among the available rebinning techniques, Single-Slice Rebinning (SSRB) offers a computationally efficient approach.

Objective: This study aimed to evaluate the influence of varying span and Maximum Ring Difference (MRD) parameters in SSRB on the image quality of the Xtrim PET scanner.

Unexpected transient femoral nerve palsy following epidural catheterization in total hip arthroplasty: A rare case report.

Introduction And Importance: Total hip arthroplasty is frequently performed under spinal anesthesia, which is generally safe. However, rare neurological complications, such as femoral nerve palsy, may occur. This report describes an unprecedented case of transient femoral nerve palsy following epidural catheterization in total hip arthroplasty.

Hybrid Fixation Technique for Femoral Stem Revision in B3 Periprosthetic Fractures: A Report of Two Cases.

Periprosthetic femoral fractures (PPFs) are challenging complications following total hip arthroplasty, especially in cases with compromised bone stock. We present 2 cases of Vancouver Type B3 PPF treated with a monoblock cementless long-stem prosthesis, using cement only for distal fixation. This technique provided initial stability, allowing early mobilization and eventual fracture healing with bony ingrowth.

Association of Anti-Müllerian Hormone on Oocyte Maturation, Fertilization, and Pregnancy Rates in Patients under Assisted Reproductive Technology Cycles: A Cross-Sectional Study.

Background: Ovarian reserve is one of the most important factors that influences the success of assisted reproductive technology (ART). Recently, the role of anti-müllerian hormone (AMH) in ART has been investigated as a marker for the prediction of ovarian response. We aim to examine this relationship within a large Iranian population.

Conversion Total Hip Arthroplasty in Patients With Osteopetrosis: Insights From Two Unique Cases.

Case: Two patients with osteopetrosis underwent conversion total hip arthroplasty (THA) after failure of internal fixation due to hip fractures. We experienced challenges, including difficulty of hardware removal, remaining of previous broken screws in the canal, difficulty in finding the femoral canal, and an intraoperative acetabulum fracture. Despite complications, both patients achieved satisfactory functional outcome after surgery at the latest follow-up.
