Purpose To assess and compare the incidence of abnormal findings detected during non-contrast-enhanced whole-body magnetic resonance imaging (WB-MRI) in general population two age groups: (1) 50 years old younger; (2) over old. Materials Methods The analysis included 666 WB-MRIs performed on a 1.5-T scanner between December 2009 June 2013 private hospital 451 patients younger 215 following images were obtained: T2-STIR (whole body-coronal plane), spine-sagittal), T2-TSE with fat-saturation...
To compare the efficacy of two quantitative methods for discrimination between benign and malignant focal liver lesions (FLLs): apparent diffusion coefficient (ADC) values T2 relaxation times. Seventy-three patients with 215 confirmed FLLs (115 benign, 100 malignant) underwent 1.5-T MRI respiratory-triggered single-shot SE DWI (b = 50, 400, 800) dual-echo T2TSE (TR 3,000 ms; TE1 84 TE2 228 ms). ADC times were calculated. Sensitivity, specificity accuracy both techniques in diagnosing...
Differentiating between dysthyroid optic neuropathy (DON), which requires urgent therapy to prevent blindness, and moderate-to-severe Graves orbitopathy (GO) remains challenging. There is no pathognomonic feature of DON in either ophthalmological or radiological examinations.Our aim was investigate the prevalence signs magnetic resonance imaging (MRI) patients with very severe GO.Two researchers reassessed MRI scans 23 consecutive (46 eyes) active, GO 14 (23 GO. Typical include apical...
Vestibular schwannomas (VSs) represent the most common cerebellopontine angle tumors, posing a challenge in preserving facial nerve (FN) function during surgery. We employed Extreme Gradient Boosting machine learning classifier to predict long-term FN outcomes (classified as House-Brackmann grades 1-2 for good and 3-6 bad outcomes) after VS
Carpal tunnel syndrome rarely occurs in children. We retrospectively analyzed clinical data of 11 patients aged 5-17 diagnosed with carpal at a single pediatric neuromuscular center. Nerve conduction studies were performed according to the American Association Electrodiagnostic Medicine recommendations. Additional imaging tests wrist 10 patients. In our group children, was idiopathic only 1 case. remaining subjects, it secondary congenital bone anomaly (6), hypothyroidism (2), or myopathic...
Internal carotid artery (ICA) injury is the most dangerous and life-threatening complication in patients operated on due to parasellar tumors via a minimally invasive endoscopic endonasal approach. Sphenoid septal attachment ICA protuberance within sphenoid sinus was found be one of anatomical risk factors for during transsphenoidal surgery.To determine relationship between septa or paraclival internal prominence based our own material literature review.The axial plane scans computed...
Purpose To evaluate whether pyramidal tracts course alterations observed in diffusion tensor tractography (DTT) cases of brainstem and intramedullary spinal cord tumors reflect patient clinical status prognosis. Materials Methods For this purpose, we assessed 17 patients relationships between DTT (classified into four categories: unaffected; displaced or interspaced; partially disintegrated completely disintegrated) performed on a 1.5 Tesla scanner the presence preoperative motor deficits,...
Stem cells (SCs) may constitute a perspective alternative to pharmacological treatment in neurodegenerative diseases. Although the safety of SC transplantation has been widely shown, their clinical efficiency amyotrophic lateral sclerosis (ALS) is still be proved. It not only due limited number studies, small groups, and fast but nonlinear disease progression also lack objective methods able show subtle changes. Preliminary guidelines for cell therapy have recently proposed by group ALS...
Background: Parasellar meningiomas, which may invade the cavernous sinus, pose a significant challenge to neurosurgeons due high risk of postoperative neurological deficits associated with aggressive resection intracavernous part tumour. Therefore, subtotal tumour removal followed by observation or radiotherapy for residual meningioma in sinus is recommended. This retrospective study aimed identify prognostic factors influencing recurrence and progression-free survival (PFS) parasellar...
Recent attempts to utilize diffusion tensor imaging (DTI) identify the extent of microinfiltration a tumor in brain have been successful. It was therefore speculated that this technique could also be useful spinal cord. The aim study differentiate between infiltrating and noninfiltrating intramedullary tumors using DTI-derived metrics.The group consisted 6 patients with 12 cord tumors. Conventional magnetic resonance (MRI) gadolinium administration performed followed by DTI. Fractional...
To investigate the effect of gadoxetic acid disodium (Gd-EOB-DTPA) on T2 relaxation times and apparent diffusion coefficient (ADC) values liver focal lesions a 1.5-T system.Magnetic resonance (MR) studies 50 patients with 35 were retrospectively analyzed. All examinations performed at 1.5T included T2-weighted turbo spin-echo (TSE) diffusion-weighted (DW) images acquired before after intravenous administration Gd-EOB-DTPA. assess this hepatobiliary contrast agent TSE DW ADC FLLs calculated...
The study aimed to describe the methodology and detailed interpretation of magnetic resonance imaging (MRI) in patients with Ménière's disease (MD).MRIs were performed on a 3T scanner. three-dimensional fluid-attenuated inversion recovery (3D-FLAIR) sequence 4 hours after double dose intravenous contrast was added standard MRI protocol clinically diagnosed MD. findings 7 unilateral MD analysed using 2 qualitative grading systems by Barath Bernaerts.In MRI, following changes group observed:...
Noonan syndrome (NS) is one of the most common genetic conditions inherited mostly in an autosomal dominant manner with vast heterogeneity clinical and features. Patients NS might have speech disturbances, memory attention deficits, limitations daily functioning, decreased overall intelligence. Here, 34 patients 23 healthy controls were enrolled a study involving gray white matter volume evaluation using voxel-based morphometry (VBM), connectivity measurements diffusion tensor imaging (DTI),...
One of the most common cardiac tumors is myxoma. Despite its predominantly benign course, diverse cardiological, systemic as well neurological complications have been reported.We are first from Poland to present case a patient with multiple central nervous system metastases associated left atrial Various diagnostic, neuroradiological and histopathological procedures were described. The underwent surgery.Follow-up studies excluded recurrence heart tumor confirmed partial resolution brain...
The study aimed to compare the consistency of MRI interpretation endolymphatic hydrops qualitative assessment inner ear structures performed by independent observers. with a delayed post-contrast 3D-FLAIR sequence was visualize EH in patients suspected having or diagnosed MD. scans were analyzed independently three In total, 220 ears evaluated and, these, 75 had definite MD, five probable 67 other Menieriform symptoms, and 73 asymptomatic. Significant differences cochlear (CoEH) grading...
Pathology of the spinal venous system, unlike that arterial is rarely considered as a possible cause clinical symptoms. As imaging features anatomy and its diseases are not well-known, related pathologies may be overlooked or misdiagnosed. The major noninvasive technique enabling optimal visualization plexuses magnetic resonance (MRI). We report MRI findings from three cases plexus engorgement different etiologies resulted in neurologic symptoms, including radiculopathy and/or back pain....
