High Prevalence of Spinal Magnetic Resonance Imaging Findings in Asymptomatic Young Adults (18-22 Yrs) Candidate to Air Force Flight.

Study Design: Cross-sectional, retrospective, magnetic resonance (MR) imaging study, performed during cadets' selection procedures of the Italian Air Force Academy.

Objective: To assess the prevalence of spinal MR imaging findings in asymptomatic young adults (18-22 yrs) candidate to Air Force Flight.

Summary Of Background Data: Spinal MR imaging findings are frequently detected in asymptomatic subjects.

Simultaneous PET/MRI in assessing the response to chemo/radiotherapy in head and neck carcinoma: initial experience.

The purpose of the study was to assess by simultaneous positron emission tomography/magnetic resonance imaging (PET/MRI) the response to chemotherapy (CHT) and/or radiotherapy (RT) in patients with head and neck squamous cell carcinoma (HNSCC). Five patients with HNSCC underwent simultaneous PET/MRI examination before and after CHT and/or RT. Standard uptake volume (SUV), apparent diffusion coefficient (ADC), Ktrans, Kep, Ve, and iAUC pre- and post-treatment values were extracted and compared.

Clinical impact of coronal-STIR sequence in a routine lumbar spine MR imaging protocol to investigate low back pain.

Aim of this study is to assess the clinical impact of coronal short tau inversion recovery (STIR)-weighted magnetic resonance (MR) sequence, when acquired in a lumbar spine MR imaging protocol, in detecting significant extraspinal imaging findings in patients with low back pain (LBP).We retrospectively evaluated 931 lumbar spine MR examinations of patients with LBP. Extraspinal MR imaging findings were categorized as: probably related to LBP (Category 1), not related to LBP but with relevant implications on patient's care (Category 2), and not related to LBP without significant implications on patient's care (Category 3).

An Evaluation of the Benefits of Simultaneous Acquisition on PET/MR Coregistration in Head/Neck Imaging.

Coregistration of multimodal diagnostic images is crucial for qualitative and quantitative multiparametric analysis. While retrospective coregistration is computationally intense and could be inaccurate, hybrid PET/MR scanners allow acquiring implicitly coregistered images. Aim of this study is to assess the performance of state-of-the-art coregistration methods applied to PET and MR acquired as single modalities, comparing the results with the implicitly coregistration of a hybrid PET/MR, in complex anatomical regions such as head/neck (HN).

Multiparametric evaluation by simultaneous PET-MRI examination in patients with histologically proven laryngeal cancer.

Objectives: To evaluate the relationship between metabolic 18Fluoro-Deoxyglucose-Positron Emission Tomography (18FDG/PET) and morpho-functional parameters derived by Magnetic Resonance Imaging (MRI) in patients with histologically proven laryngeal cancer. To assess the clinical impact of PET/MRI examination on patient's staging and treatment planning.

Methods: 16 patients with histologically proven laryngeal cancer were enrolled and underwent whole body PET/CT followed by a dedicated PET/MRI of the head/neck region.
