چکیده اصلی

We report the 18 F-FDG PET/CT findings of IgG4-related autoimmune hepatitis mimicking hepatic malignancy in a 52-year-old man. The patient presented with intermittent fever, abdominal pain, and significantly elevated tumor markers. Initial evaluation with contrast-enhanced CT suggested hepatic malignancy. 18 F-FDG PET/CT demonstrated heterogeneous hepatic FDG uptake and multiregional hypermetabolic lymphadenopathy. Diagnosis was confirmed by cervical lymph node biopsy and a favorable clinical response to glucocorticoid therapy.

Comprehensive Approach to Prostate Cancer Metastasis Mimics at Prostate-Specific Membrane Antigen PET/CT.

Prostate-specific membrane antigen (PSMA) PET has transformed prostate cancer (PCa) imaging. Nevertheless, major diagnostic pitfalls remain as PSMA expression is not exclusive to PCa and may also occur in physiologic tissues and a range of benign and malignant conditions. These conditions may mimic PCa metastases, leading to potential misinterpretation. Accurate risk assessment of suspected lesions using PSMA PET/CT requires the integr…

Preoperative porta hepatis-to-hepatic surface ratio on 24-h delayed hepatobiliary scintigraphy is associated with jaundice clearance after Kasai portoenterostomy.

PURPOSE: Biliary atresia (BA) often requires liver transplantation despite Kasai portoenterostomy (KPE). The prognostic role of hepatobiliary scintigraphy remains unclear. METHODS: Twenty-three infants undergoing KPE between 2017 and 2024 were retrospectively analyzed. Patients without 6-h bowel activity on technetium-99 m PMT hepatobiliary scintigraphy underwent 24-h delayed imaging. The primary endpoint was jaundice clearance (total …

Cost-effectiveness of ferumoxtran-enhanced macrophage-specific-MRI and PSMA-PET/CT versus ePLND for nodal staging in primary prostate cancer: a decision analysis based on updated phase-3 trial data.

BACKGROUND AND OBJECTIVE: Accurate nodal staging in intermediate- to high-risk prostate cancer (PCa) is crucial for treatment decisions. While extended pelvic lymph node dissection (ePLND) is the standard, it is invasive and has a low diagnostic yield. A 2019 analysis suggested that non-invasive imaging such as PSMA-PET/CT and ferumoxtran-enhanced macrophage-MRI (m-MRI) is cost-effective, but at the possible expense of a small QALY los…

Dual Dopaminergic and Limbic-Cognitive Contributions to Gait Parameters in De Novo Parkinson Disease.

BACKGROUND AND OBJECTIVES: Parkinson disease (PD) is a progressive neurodegenerative disease in which gait impairment is a common and disabling clinical feature. We aimed to characterize the independent and mediated contributions of striatal dopamine transporter (DAT) availability and gray matter (GM) volume to quantitative gait impairment in de novo PD. METHODS: In this prospective study, we consecutively recruited patients with de no…
