The purpose of this article is to define the relations symphysis pubis and capsular tissues adductor rectus abdominis soft-tissue attachments on cadaver dissection correlate with MRI anterior pelvis.Seventeen cadavers (8 males 9 females; mean age, 80 years) were dissected bilaterally. Rectus muscles traced further pubic defined. Ten asymptomatic (mean 17; age range, 16.5-29 male athletes underwent 1.5-T pelvis two surface microcoils (each 42 mm in diameter). An axial T2-weighted turbo...
Purpose: Approximately 25% of patients with traumatic brain injury (TBI) may develop partial or complete hypopituitarism. The causative mechanisms involved in its development are not clear. To the authors' knowledge, there have been no recent morphologic studies pituitary following TBI.Methods: characterize resultant histologic changes, this study investigated pituitaries 42 who died a motor vehicle accident, all from Mayo Tissue Registry. Twelve instantly at scene accident (Group I) whereas...
Purpose To provide a more detailed investigation of hippocampal subfields using 7T magnetic resonance imaging (MRI) for the identification sclerosis in temporal lobe epilepsy (TLE). Materials and Methods Patients ( n = 13) with drug‐resistant TLE previously identified by conventional as having (HS) or not (nine without HS, four HS) 20 age‐matched healthy controls were scanned compared MRI protocol. Using manual segmentation scheme to delineate subfields, subfield‐specific volume changes...
OBJECT The relationship between headaches, pituitary adenomas, and surgical treatment of adenomas remains unclear. authors assessed the severity predictors self-reported headaches in patients referred for surgery evaluated impact endoscopic transsphenoidal on headache quality life (QOL). METHODS In this prospective study, 79 with underwent resection completed Headache Impact Test (HIT-6) 36-Item Short Form Health Survey (SF-36) QOL questionnaire preoperatively at 6 weeks months...
Recently published North American Imaging in Multiple Sclerosis guidelines call for derivation of a specific radiologic definition MS WM lesions and mimics. The purpose this study was to use SWI magnetization-prepared FLAIR images sensitive differentiation from benign using the morphologic characteristics lesions.Seventeen patients with relapsing-remitting 18 healthy control subjects were enrolled retrospectively. For each subject, multiecho gradient-echo acquired 7T MR imaging. Optimized...
BACKGROUND: O-6-methylguanine-DNA methyltransferase (MGMT) is a DNA repair enzyme that counteracts chemotherapeutic cytotoxicity of alkylating agents such as temozolomide. Low levels MGMT expression have been shown to correlate with longer survival in glioma patients treated The same true pituitary adenomas. OBJECTIVE: We investigated the immunohistochemical variety corticotroph adenoma subtypes determine potential utility temozolomide therapeutic agent. METHODS: tumors consisted 40 cases...
Bone invasive skull base meningiomas are a subset of that present unique clinical challenge due to brain and neural structure involvement limitations in complete surgical resection, resulting higher recurrence need for repeat surgery. To date, the pathogenesis meningioma bone invasion has not been investigated. We investigated immunoexpression proteins implicated other tumor types establish their invasion.Retrospective review our database identified operated on at institution over past 20...
Objective. We investigated the correlation between immunohistochemical expression of pituitary tumor transforming gene (PTTG) and adenoma subtype. Methods. Pituitary adenomas (n = 89) were stained for PTTG using streptavidin—biotin—peroxidase complex method a monoclonal antibody. Results. staining was found to be cytoplasmic with pronounced paranuclear pattern. Reactivity highest in growth hormone (GH) as compared other tumors, including prolactin (PRL), follicle-stimulating...
Purpose: To establish reporting adherence to the Checklist for Artificial Intelligence in Medical Imaging (CLAIM) diagnostic accuracy AI studies with highest Altmetric Attention Scores (AAS), and compare completeness of between peer-reviewed manuscripts preprints. Methods: MEDLINE, EMBASE, arXiv, bioRxiv, medRxiv were retrospectively searched 100 medical imaging journals preprint platforms AAS since release CLAIM June 24, 2021. Studies evaluated 42-item checklist comparison The impact...
Object The aim of this work was to investigate the immunohistochemical expression nestin, a member intermediate filament family, in adenohypophysial vasculature during development and progression pituitary infarction. Methods Forty-five nontumorous adenohypophyses 34 adenomas various types, all exhibiting acute or healing infarcts, were examined immunohistochemically using streptavidin-biotin-peroxidase complex method. Results In both without infarction, nestin expressed only few capillaries...
The aim of this study is to compare longitudinal two-dimensional (2-D) and three-dimensional (3-D) ultrasound (US) estimates ventricle size in preterm neonates with posthemorrhagic ventricular dilatation (PHVD) using quantitative measurements the lateral ventricles. Cranial 2-D US 3-D images were acquired from neonatal patients diagnosed PHVD within 10 min each other one two times per week analyzed offline. Ventricle index, anterior horn width, third thalamo-occipital distance measured on...
