Diagnostic Performance of PSMA-Based 18 F-DCFPyL PET/CT in Prostate Cancer Patients After Definitive Treatment With PSA Level ≤0.2 ng/mL.

Purpose: The aim of this study was to investigate the role of 18 F-DCFPyL PET/CT in the evaluation of prostate cancer (PC) patients after definitive treatment and with low-level prostate-specific antigen (PSA) level of ≤0.2 ng/mL.

Patients And Methods: This retrospective study was conducted in PC patients who received definitive treatments with PSA level of ≤0.

Comparison of PSMA-based F-DCFPyL PET/CT and Tc-99m MDP bone scan in detection of bone metastasis in prostate cancer.

While Tc-99m MDP bone scan (BS) remains the conventional standard for detection of bone metastasis in prostate cancer, newly FDA-approved imaging with PSMA-based F-DCFPyL PET/CT has shown promise for early detection of metastatic disease. However, a paucity of data remains in the diagnostic accuracy of PSMA PET/CT in detecting bone metastasis compared to BS. This retrospective study included 91 patients who received both BS and PSMA PET/CT within a 3-month interval from August 2021 to February 2022.

Acetabular Reconstruction With the Medial Protrusio Technique for Complex Primary and Revision Total Hip Arthroplasties.

Background: In the setting of acetabular deficiency during total hip arthroplasty (THA), the medial protrusio technique (MPT) allows for increased component coverage while avoiding excessive component abduction or elevation of the hip center. The technique involves controlled reaming through the medial acetabular wall while maintaining the continuity of the anterior and posterior columns. The purpose of this study is to analyze the results of the largest reported series to date of primary and revision THAs using the MPT.
