Few studies have shown MR imaging features and ADC correlating with molecular markers survival in patients glioma. Our purpose was to correlate subtyping adult diffuse gliomas.Presurgical MRIs maps of 131 gliomas available data from The Cancer Genome Atlas were reviewed. features, (obtained by ROIs within the lowest area), mean relative values evaluated predict isocitrate dehydrogenase (IDH) mutation, 1p/19q codeletion status, MGMT promoter methylation, overall survival.IDH wild-type tended...
Although boron neutron capture therapy (BNCT) is a promising treatment option for malignant brain tumors, the optimal BNCT parameters patients with immediately life-threatening, end-stage tumors remain unclear. We performed on 34 and analyzed relationship between survival outcomes parameters. Before BNCT, MRI 18F-BPA-PET analyses were conducted to identify tumor location/distribution tumor-to-normal tissue uptake ratio (T/N ratio) of 18F-BPA. No severe adverse events observed (grade ≥ 3)....
Abstract Artificial intelligence (AI) has been applied with considerable success in the fields of radiology, pathology, and neurosurgery. It is expected that AI will soon be used to optimize strategies for clinical management patients based on intensive imaging follow-up. Our objective this study was establish an algorithm by which automate volumetric measurement vestibular schwannoma (VS) using a series parametric MR images following radiosurgery. Based sample 861 consecutive who underwent...
Purpose To retrospectively evaluate the clinical and technical factors related to outcomes of endovascular management in patients with head-and-neck cancers associated post-irradiated carotid blowout syndrome (PCBS). Materials Methods Between 2000 2013, 96 PCBS underwent management. The 40 pathological lesions located external artery were classified as group 1 treated embolization. other 56 trunk divided into 2 groups follows: 2A comprised 38 embolization, 2B 18 stent-graft placement....
The role of surgical resection for hepatocellular carcinoma with tumor thrombi involving the major portal vein is controversial because a high operative risk and poor prognosis. Previously, was performed only when were limited to first branch without extension bifurcation.Concomitant liver may be beneficial in patients extending bifurcation.Retrospective review.University hospital, tertiary referral center.Among 368 who underwent curative resection, involvement occurred 112 patients. Fifteen...
OBJECTIVE Gamma Knife radiosurgery (GKRS) is frequently used to treat residual or recurrent nonfunctioning pituitary macroadenomas. There no consensus as whether GKRS should be early after surgery if withheld until there evidence of imaging-defined progression tumor. Given the high incidence adenoma subtotal resection over time, present study intended evaluate effect timing on outcome. METHODS This a multicenter retrospective review patients with macroadenomas who underwent transsphenoidal...
OBJECTIVE Gamma Knife surgery (GKS) is a promising treatment modality for patients with vestibular schwannomas (VSs), but small percentage of have persistent postradiosurgical tumor growth. The aim this study was to determine the clinical and quantitative MRI features VS as predictors long-term control after GKS. METHODS authors performed retrospective all treated GKS using Leksell Unit between 2005 2013 at their institution. A total 187 who had minimum 24 months radiological assessment...
This study investigates motion simulation and compensation techniques for airborne Synthetic Aperture Radar (SAR) to enhance imaging accuracy quality. SAR utilizes platform create a synthesized long aperture, improving azimuth resolution independently of frequency distance. However, unexpected motion, such as from wind or turbulence, can introduce non-linear trajectory changes, causing Doppler shifts that blur images. To address this, we simulate trajectories under various conditions,...
The purpose of this study was to investigate whether the diameter superior hemorrhoidal vein on preoperative CT can predict presence lymphovascular invasion (LVI).This recruited 102 patients with treatment-naive rectal cancers. diameters and inferior mesenteric (IMV) pretreatment postoperative pathologic reports were reviewed. Univariate analysis receiver operating characteristic curve applied determine correlation between clinical factors features IMV.The significantly higher in LVI than...
<h3>BACKGROUND AND PURPOSE:</h3> Sinus stenosis occasionally occurs in dural arteriovenous fistulas. impedes venous outflow and aggravates intracranial hypertension by reversing cortical drainage. This study aimed to analyze the likelihood of sinus its impact on cerebral hemodynamics various types <h3>MATERIALS METHODS:</h3> Forty-three cases fistula transverse-sigmoid were reviewed divided into 3 groups: Cognard type I, IIa, with double peak sign (occurrence 2 peaks time-density curve...
Background: Magnetic resonance diffusion-weighted imaging (DWI) has been widely used clinically in diagnosis of intracranial disorders. The purpose current study was to present a quantitative method direct measuring the DWI signal intensity brain gliomas on monitors hospital picture archiving and communicating system (PACS) for grading gliomas. Methods: This recruited 135 patients with treatment-naïve Direct measurement selected tumoral regions interest (ROIs) by PACS performed all patients....
<h3>BACKGROUND AND PURPOSE:</h3> Suprasellar papillary craniopharyngiomas and germ cell tumors in adults share some clinical imaging similarities but have different therapeutic strategies outcomes. This study aimed to evaluate the pretreatment diagnosis of these 2 improve outcome. <h3>MATERIALS METHODS:</h3> We retrospectively enrolled 18 with 17 tumors. The MR findings were evaluated, including signal change anatomic extension. medical records reviewed collect findings, management,...
Current practice of revascularization for carotid stenosis (CS) primarily relies on symptoms and degree stenosis. Other parameters, such as collateral circulation cerebral time (CCT), might influence the stroke risk in CS. This study was conducted to (1) investigate whether CCT is more associated with symptomatic CS than (2) elucidate associations among stenosis, status, CCT.From 2010 2016, 82 patients unilateral were enrolled DSA divided into asymptomatic groups based clinical presentation....
Brainstem tumors are heterogenous and cancerous glioma arising from the midbrain, pons, medulla that relatively common in children, accounting for 10% to 20% of all pediatric brain tumors. However, prognosis aggressive brainstem gliomas remains extremely poor despite treatment with chemotherapy radiotherapy. That means there many life-threatening patients who have exhausted available options beginning face end-of-life stage. Therefore, unique properties highly selective heavy particle...
<h3>BACKGROUND AND PURPOSE:</h3> Flat detector CT has been increasingly used as a follow-up examination after endovascular intervention. Metal artifact reduction successfully demonstrated in coil mass cases, but only small series. We attempted to objectively and subjectively evaluate the feasibility of metal with various metallic objects lengths. <h3>MATERIALS METHODS:</h3> retrospectively reprocessed flat data 28 patients (15 men, 13 women; mean age, 55.6 years) they underwent treatment (20...
Multiple system atrophy cerebellar type (MSA-C) and spinocerebellar ataxia 3 (SCA3) demonstrate similar manifestations, including ataxia, pyramidal extrapyramidal signs, as well signal intensity changes in the cerebellum brainstem. MSA-C SCA3 cannot be clinically differentiated through T1-weighted magnetic resonance imaging (MRI) alone; therefore, clinical consensus criteria genetic testing are also required. Here, we used diffusion tensor (DTI) to measure water molecular of white matter...
