Abstract Objective Presurgical differentiation between astrocytomas and oligodendrogliomas remains an unresolved challenge in neuro-oncology. This research aims to provide a comprehensive understanding of each tumor’s DSC-PWI signatures, evaluate the discriminative capacity cerebral blood volume (CBV) percentage signal recovery (PSR) percentile values, explore synergy CBV PSR combination for pre-surgical differentiation. Methods Patients diagnosed with grade 2 3 IDH-mutant 1p19q-codeleted...
<h3>SUMMARY:</h3> The rapid spread of the coronavirus disease 2019 (COVID-19) pandemic has shaken hospitals worldwide. Some authors suggest that neurologic involvement could further complicate disease. This descriptive study is a cross-sectional review 103 patients diagnosed with COVID-19 who underwent neuroimaging (of total 2249 in our center). Analyzed variables were symptoms and acute imaging findings. most frequent motivated examinations mild nonfocal symptoms, code stroke (refers to...
Abstract The skull vault, formed by the flat bones of skull, has a limited spectrum disease that lies between fields neuro- and musculoskeletal radiology. Its unique abnormalities, as well other ubiquitous ones, present particular features in this location. Moreover, some benign entities region may mimic malignancy if analyzed using classical bone-tumor criteria, proper patient management requires being familiar with these presentations. This article is structured practical review offering...

The purpose of this study was to evaluate whether single‐voxel 1 H MRS could add useful information conventional MRI in the preoperative characterisation type and grade brain tumours. examinations from a prospective cohort 40 consecutive patients were analysed double blind by radiologists spectroscopists before histological diagnosis known. had only MR spectra, whereas both images basic clinical details (age, sex presenting symptoms). Then, exchanged their predictions re‐evaluated initial...
Abstract Glioblastoma is the most common primary brain tumor. Standard therapy consists of maximum safe resection combined with adjuvant radiochemotherapy followed by chemotherapy temozolomide, however prognosis extremely poor. Assessment residual tumor after surgery and patient stratification into prognostic groups (i.e., volume) currently hindered subjective evaluation enhancement in medical images (magnetic resonance imaging [MRI]). Furthermore, objective evidence defining optimal time to...
MRI is essential for monitoring multiple sclerosis (MS). Contrast-enhanced T1-weighted imaging (T1WI+C) detects active inflammatory lesions indicating blood-brain barrier breakdown and relevant disease treatment optimization. Susceptibility-weighted (SWI) may be included in the protocol detecting MS-specific features, such as presence of central veins or paramagnetic rim lesions. However, post-contrast SWI (SWI+C) has an inherent "T1 shine-through effect" that enables visualization...
Extra-articular distal radial malunion may result in poor functional outcome. This biomechanical study aims to investigate whether changes the shape of radius (length and/or inclination) influence muscle control carpal rotational alignment. Nine cryopreserved cadaveric specimens were used reproduce six conditions: (1) unaltered anatomy; (2) 20° dorsal tilt; (3) anterior (4) 4 mm shortening; (5) tilt and (6) shortening. Combined shortening tilting reduced supination effect abductor pollicis...
Objectives: To compare the performance of 3D T1 turbo spin echo (3DT1TSE) and field (3DT1TFE) MRI in detecting gadolinium-enhancing lesions multiple sclerosis (MS). Methods: We retrospectively analyzed 255 3T MRIs from MS patients, each including post-contrast 3DT1TSE 3DT1TFE sequences. Two blinded readers independently assessed enhancing per sequence. A consensus review, incorporating longitudinal imaging additional sequences, served as reference standard. Results: The identified 70 31...
The development of new drugs for the treatment progressive multiple sclerosis (MS) highlights need prognostic biomarkers. Phase-rim lesions (PRLs) have been proposed as markers disease but are difficult to identify and quantify. Previous studies identified T1-hypointensity in PRLs. aim this study was compare intensity profiles PRLs non-PRL white-matter (nPR-WMLs) on three-dimensional T1-weighted turbo field echo (3DT1TFE) MRI. We then evaluated performance a derived metric surrogate...
There is a large range of survival times in patients with HGA that can only be partially explained by histologic grade and clinical aspects. This study aims to retrospectively assess the predictive value single-voxel (1)H-MRS regarding HGA.Pretreatment 187 produced 180 spectra at STE (30 ms) 182 LTE (136 ms). Patients were dichotomized into 2 groups according better or worse than median. The compared using Mann-Whitney U test. points on spectrum most significant differences selected for...
ABSTRACT BACKGROUND AND PURPOSE SARS‐CoV‐2 causes multiorgan disease due to altered coagulability and microangiopathy. Patients may have an increased risk of cerebrovascular accidents (CVA). Our objective was analyze clinical neuroimaging characteristics patients with ischemic CVA during the pandemic peak in our region, order identify atypical presentations. METHODS We performed a cross‐sectional analysis admitted under code‐stroke protocol center final diagnosis brain infarction. analyzed...
<h3>BACKGROUND AND PURPOSE:</h3> Current protocols in patients with glioblastoma include performing an MR examination shortly after surgery and then 2–6 weeks ending concomitant chemoradiotherapy. The assessment of this first postradiotherapy is challenging because the pseudoprogression phenomenon may appear. aim study was to explore if before radiation therapy (preradiotherapy imaging) could improve radiologic glioblastoma. <h3>MATERIALS METHODS:</h3> A preradiotherapy imaging prospectively...
DSC-PWI has demonstrated promising results in the presurgical diagnosis of brain tumors. While most studies analyze specific parameters derived from time-intensity curves, very few have directly analyzed whole curves. The aims this study were following: 1) to design a new method postprocessing which renders normalized and 2) test its feasibility performance on primary central nervous system lymphoma.Diagnostic MR imaging patients with histologically confirmed lymphoma retrospectively...
Paramagnetic rim lesions (PRLs), usually identified in susceptibility-weighted imaging (SWI), are a promising prognostic biomarker of disability progression multiple sclerosis (MS). However, SWI is not routinely performed clinical practice. The objective this study to define novel sign, the T1-dark rim, identifiable standard 3DT1 gradient-echo inversion-recovery sequence, such as 3D T1 turbo field echo (3DT1FE) and explore its performance surrogate PRLs.
Immunodeficiency-associated CNS lymphoma may occur in different clinical scenarios beyond AIDS. This subtype of is diffuse large B-cell and Epstein-Barr virus-positive. Its accurate presurgical diagnosis often unfeasible because it appears as ring-enhancing lesions mimicking glioblastoma or metastasis. In this article, we describe clinicoradiologic features test the performance DSC-PWI metrics for identification.Patients without AIDS with histologically confirmed virus-positive primary...
Despite considerable literature on the functional anatomy of hominoid upper limb, there are no quantitative approaches relating to bone design and resulting muscular-activity enhancement.

Using conventional scan images a human forearm for three positions, develops an original biomechanical model that defines as mathematical function expressing...
Brain tumors can result in displacement or destruction of important white matter tracts such as the inferior fronto-occipital fascicle (IFOF). Diffusion tensor imaging (DTI) assess extent this effect and potentially provide neurosurgeons with an accurate map to guide tumor resection; analyze IFOF patterns temporoinsular gliomas based on grading topography temporal lobe; whether these follow a predictable pattern, assist maximal resection while preserving function.Thirty-four patients...
