Background And Objectives: We assessed the agreement between prostate-specific antigen (PSA) and imaging responses using whole-body magnetic resonance imaging (wbMRI). Our aim was to explore the potential prognostic value of PSA and wbMRI responses in metastatic hormone-naïve prostate cancer (mHNPC) and castration-resistant PC (mCRPC).
Methods: wbMRI was prospectively performed in 37 patients with mHNPC and 51 with mCRPC before and after 6-12 mo of androgen deprivation therapy and an androgen receptor pathway inhibitor (ARPI).
Article Synopsis
- MRI is effective at identifying bone marrow involvement in multiple myeloma but struggles with detecting bone lesions, prompting a study to test new MRI techniques (ZTE and BB) against whole-body CT as a reference.
- The study included 47 patients diagnosed with multiple myeloma or at high risk, assessing the performance of ZTE and BB MRI sequences alongside PET/CT scans for detecting osteolytic lesions.
- Results showed that experienced radiologists achieved high accuracy (98%) with both MRI techniques, but there were noticeable discrepancies in detection rates across different regions, particularly with an increased false-negative rate in the spine when using ZTE.
Background: In head and neck squamous cell carcinoma (HNSCC), [F]FDG PET/CT is recommended for detecting recurrent disease and in the initial staging for evaluating distant metastases, but its use in detecting cervical lymph metastases remains unclear. The aim of this study is to evaluate and compare the diagnostic accuracy of [F]FDG-PET/CT using visual and semi-quantitative analyses for detecting the nodal involvement in HNSCC.
Methods: We analyzed consecutive patients who underwent a preoperative [F]FDG-PET/CT and neck dissection for HNSCC at our tertiary hospital.
Purpose: The purpose of this study was to compare two-dimensional (2D) T2-weighted, contrast-enhanced 2D T1-weighted and contrast-enhanced three-dimensional (3D) T1-weighted Dixon MRI sequences to assess disease activity using the RAMRIS scoring system in hands of patients with early rheumatoid arthritis.
Materials And Methods: Twenty-five patients (19 women, 6 men; mean age 51.4 years ± 12.
To test and compare different intensity standardization approaches for whole-body multi-parametric MR images, aiming to compensate voxel intensity differences between scans. These differences, common for magnetic resonance imaging, pose problems in image quantification, assessment of changes between a baseline and follow-up scan, and hinder performance of image processing and machine learning algorithms.In this work, we present a comparison on the accuracy of intensity standardization approaches with increasing complexity, for intra- and inter-patient multi-parametric whole-body MRI.
