LATEST DEVELOPMENTS IN ANAPLASTIC THYROID CARCINOMA MANAGEMENT IN 2024: Anaplastic thyroid carcinomas (ATCs) represent a rare and undifferentiated form of thyroid cancer with a poor prognosis, typically marked by a median overall survival of four to ten months. However, recent advances have shown improvements due to the more systematic application of molecular testing, targeted therapies, and immunotherapy, alongside the establishment of rapid specialized care protocols in expert centers. Clinically, ATCs often present as a rapidly enlarging cervical mass originating from the thyroid, causing neck, pain and tenderness, dyspnea and dys-phagia, and associated lymphadenopathy, typically in elderly patients.

Multiple sclerosis (MS) is a central nervous system disease involving gray and white matters. Transcranial magnetic stimulation (TMS) and magnetic resonance imaging (MRI) could help identify potential markers of disease evolution, disability, and treatment response. This work evaluates the relationship between intracortical inhibition and facilitation, motor cortex lesions, and corticospinal tract (CST) integrity.

: We aimed to evaluate the prognostic value of imaging biomarkers on 18F-FDG PET/CT in extensive-stage small-cell lung cancer (ES-SCLC) patients undergoing first-line chemo-immunotherapy. In this multicenter and retrospective study, we considered two cohorts, depending on the type of first-line therapy: chemo-immunotherapy (CIT) versus chemotherapy alone (CT). All patients underwent baseline 18-FDG PET/CT before therapy between June 2016 and September 2021.

• Prediction of neurological outcome after cardiac arrest is a major ethical challenge. • Diffusion tensor imaging (DTI) is a promising prognostic tool in comatose patients assessing brain microstructural damages. • The combination of clinical data with whole-brain fractional anisotropy and mean diffusivity values appears more accurate to predict poor outcome.

Background: Survivors of severe-to-critical coronavirus disease 2019 (COVID-19) may have functional impairment, radiological sequelae and persistent symptoms requiring prolonged follow-up. This pragmatic study aimed to describe their clinical follow-up and determine their respiratory recovery trajectories, and the factors that could influence them and their health-related quality of life.

Methods: Adults hospitalised for severe-to-critical COVID-19 were evaluated at 3 months and up to 12 months post-hospital discharge in this prospective, multicentre, cohort study.

Objectives: Our aim was to evaluate the ability of magnetic resonance neurography (MRN) of the lumbo-sacral plexus (LSP) to distinguish patients with hereditary transthyretin-related amyloidosis with polyneuropathy (ATTRv-PN) from asymptomatic variant carriers (AVC) and healthy controls and to assess its prognostic value.

Methods: Three-Tesla MRN was performed in 25 consecutive ATTRv-PN patients, 18 AVC, and 10 controls including T2-w DIXON and DWI MR sequences. Two blinded readers independently assessed LSP root diameter and intraneural signal on the MRN images of each subject.

Purpose: The purpose of this study was to assess and compare the prevalence of meniscal, ligament and cartilage lesions on knee MRI in a series of age- and sex-matched patients with and without medial meniscal ossicle.

Materials And Methods: Forty-two knee MRI examinations obtained in 42 patients (36 men, 6 women; mean age, 42.5±22.

Background And Purpose: To determine the precise incidence of lesions at sites of high Aquaporin-4 expression (hAQP4) and their possible association with known neuromyelitis optica spectrum disease (NMOSD) lesions patterns.

Materials And Methods: A retrospective analysis of brain and, when available, spinal cord MRI scans of 54 NMOSD patients recruited among the French NMOSD cohort was performed. Brain lesions were annotated as MS-like, non-specific, or evocative of NMOSD.

Onco, the Regional oncology network of Northern France, in partnership with Cronor, is piloting a project to harmonize radiotherapy practice. In 2016, a working party "Quality in Radiotherapy" was set up to encourage all centres in the network to participate in regional experience feedback committees. These committee meetings allow for analysis and handling of adverse events in radiotherapy within predefined areas of expertise.

Objective: The purpose of this study is to evaluate stereoradiographic measurements of femoral torsion with different femoral positions, in comparison with CT measurements, with use of the current standard axial-slice technique. We hypothesize that CT measurements vary with femoral spatial positioning because of the resulting projection onto the CT plane, whereas stereoradiographic measurements, which are derived from a 3D reconstruction of the femur, remain constant.

Materials And Methods: Both in vitro and in vivo studies were conducted.

Non-traumatic calcifications/ossifications of the bone surface and soft tissues of the wrist, hand and fingers: a diagnostic approach.

In the absence of obvious trauma, the calcifications/ossifications of the bone surface and soft tissues of the wrist, hand and fingers can be challenging and may not be noticed or lead to unnecessary examinations and monitoring. Although these are usually benign conditions and despite a favorable spontaneous outcome, surgical resection may be required and recurrence may occur. In practice, only paraneoplastic syndromes such as secondary hypertrophic osteoarthropathy (Pierre Marie-Bamberger syndrome) may reveal a malignant tumor, most often pulmonary.

Nowadays, conventional or digitalized teleradiography remains the most commonly used tool for the study of the sagittal balance, sometimes with secondary digitalization. The irradiation given by this technique is important and the photographic results are often poor. Some radiographic tables allow the realization of digitalized spinal radiographs by simultaneous translation of X-ray tube and receptor.
