<h3>BACKGROUND AND PURPOSE:</h3> Conventional MR imaging techniques cannot produce optimal images of bone structures because has little water and a very short T2 life span. The aim this study was to investigate the clinical feasibility skull using zero TE sequence in patients with head trauma by assessing its diagnostic image quality quantitative measurement compared CT images. <h3>MATERIALS METHODS:</h3> Thirteen enrolled were assessed brain imaging. Image graded on 5-point Likert scale...
Aims: The aim of this study was to evaluate renal artery embolization in patients with spontaneous bleeding based on detailed angiographic findings and a comprehensive analysis its efficacy clinical outcomes. Materials Methods: This retrospective evaluated the outcomes 18 cases among 15 (11 men 4 women; mean age: 57.9 years) treated for at our institution between March 2017 October 2023. Data derived from abdominal computed tomography (CT) arteriography were analyzed assess effectiveness...
The objective of our study was to evaluate the quality virtual monoenergetic imaging (VMI) from dual-layer detector spectral CT and effect images obtained at low energies on detection pulmonary embolism (PE) in patients with a suboptimally enhanced artery chest CT.Of 1552 consecutive examinations performed using routine protocol tube voltage 120 kVp, 79 suboptimal enhancement (i.e., mean attenuation ≤ 180 HU) were included. artery, noise, contrast-to-noise ratio (CNR), signal-to-noise (SNR)...
Sea hare-derived compounds induce macrophage activation and reduce asthmatic parameters in mouse models of allergic asthma. These findings led us to study the role sea hare hydrolysates (SHH) cancer pathophysiology. SHH treatment-induced M1 RAW264.7 cells, peritoneal macrophages, THP-1 as did lipopolysaccharide (LPS) (+ INF-γ), whereas reduced interleukin (IL)-4 (+IL-13)-induced M2 polarization. In addition, treatment inhibited actions which have anticancer pro-cancer effects, respectively,...
Models created by the intraperitoneal injection of lipopolysaccharide (LPS) and D-galactosamine (D-GalN) have been widely used to study pathogenesis human acute liver failure (ALF) drug development. Our previous reported that oyster (Crassostrea gigas) hydrolysate (OH) had a hepatoprotective effect in LPS/D-GalN-injected mice. This was performed identify tyrosine-alanine (YA) peptide, main component OH, ALF mice model. We analyzed YA on previously known mechanisms hepatocellular injury...
Flow visualization in time-of-flight magnetic resonance angiography (TOF MRA) is limited for treated intracranial aneurysms owing to susceptibility and radiofrequency shielding.To assess the clinical usefulness of noncontrast-enhanced (MRA) using a silent scan (silent as follow-up imaging modality patients with aneurysms.A total 119 126 underwent MRA TOF during same session. Two neuroradiologists independently assessed overall image quality site 5-point Likert scale compare 2 sets. We used...
The aim of this study was to determine the relationship between lobar severity emphysema and lung cancer using automated lobe segmentation quantification methods. This included 78 patients (74 males 4 females; mean age 72 years) with following conditions: pathologically proven cancer, available chest computed tomographic (CT) scans for segmentation, quantitative scoring emphysema. analyzed each pulmonary lobe. most common location left upper (LUL) (n = 28), followed by right (RUL) 27), lower...
Background Transradial access is a well-known alternative to conventional transfemoral for interventional procedures. Recently, transradial through the "snuffbox", which lies in radial dorsal aspect of hand, has been introduced as new technique with positional versatility. In this study, we aimed evaluate clinical feasibility and safety distal procedures retrospective, multicenter study. Material & methods Distal was attempted 46 patients (36 men 10 women; mean age, 64 years) who underwent...
Abstract To investigate computed tomography and angiography findings clinical outcomes after transcatheter arterial embolization for acute upper gastrointestinal bleeding from advanced gastric cancers. From January 2005 to December 2014, 58 patients with pathologically proven cancer were treated at our institution due recalcitrant endoscopic treatment. The electronic medical records each patient reviewed presentation, endoscopy history, angiographic findings, blood transfusion requirements,...
Background and Objectives: Preoperative prophylactic balloon-assisted occlusion (PBAO) of the internal iliac arteries minimizes blood loss facilitates surgery performance, through reductions in rate uterine perfusion, which allow for better control hysterectomy with decreased rates bleeding surgical complications. We aimed to investigate maternal fetal outcomes associated PBAO use women placenta increta or percreta. Material Methods: The records 42 consecutive patients a diagnosis percreta...
Background: In this study, we present a quantitative method to evaluate the motion artifact correction (MAC) technique through morphological analysis of blood vessels in images before and after MAC. Methods: Cone-beam computed tomography (CBCT) scans 37 patients who underwent transcatheter chemoembolization were obtained, reconstructed with without MAC technique. First, two interventional radiologists selected corrected by We devised motion-corrected index (MCI) metric that analyzed...
The objective was to evaluate the incidence and degree of double-J ureteral stent (DJUS) migration. Additionally, we aimed investigate risk factors associated with migration in orthotopic neobladder group. In this retrospective study, 61 consecutive patients were included; 35 (45 DJUS placements) underwent radical cystectomy 26 (35 urinary bladder without between July 2021 March 2023. All treated a for ureteric strictures. technical success rate 100% each significantly higher group, 22 45...
Background: We aimed to assess the effectiveness and safety of transcatheter arterial embolization (TAE) in management spontaneous or traumatic psoas and/or retroperitoneal hemorrhage. Methods: This single-center retrospective study enrolled 36 patients who underwent TAE for treatment hemorrhage between May 2016 February 2024. Results: The patients’ mean age was 61.3 years. group (SG, 47.1%) showed higher rates anticoagulation therapy use compared with trauma (TG, 15.8%) (p = 0.042). TG...
We aimed to evaluate the feasibility of MR elastography (MRE) using a transpelvic approach. Thirty-one patients who underwent prostate MRE and had pathological diagnosis were included in this study. was obtained passive driver placed at umbilicus iliac crests. The shear stiffness, clinical data, conventional imaging findings cancer benign prostatic hyperplasia (BPH) compared. Inter-reader agreements evaluated intraclass coefficient class (ICC). Prostate successfully performed for all (100%...
Rationale: Splenic artery pseudoaneurysm induced by benign gastric ulcer is extremely rare and can lead to a fatal clinical situation. To the best of our knowledge, there are only five cases in literature review. Therefore, it be diagnostic challenge for radiologists clinicians because incidence. Patient concerns: The patient visited hospital due melena dizziness. Diagnoses: showed huge an exposed vessel posterior wall high body during endoscopy. Angiography revealed splenic contrast...
We retrospectively reviewed 42 patients with acute ischemic stroke who underwent endovascular treatment for tandem lesions between January 2011 and April 2017. After dividing the into two groups according to lesion type of proximal cervical ICA (complete occlusion severe stenosis), we analyzed demographic data, angiographic findings clinical outcomes. A modified Rankin Scale score ≤2 was defined as a favorable outcome.Of patients, 27 (64.3%) had complete ICA, remaining 15 high-grade...
Abstract The aim of this study was to evaluate the clinical feasibility and effectiveness bedside peripherally inserted central catheter (PICC) using portable digital radiography (DR) in intensive care unit (ICU) patients. Sixty-five ICU patients who underwent PICC were enrolled between May 2016 2017. Of these 65 patients, 45 (69.2%) procedures DR, 20 (30.8%) at intervention clinic, both performed by a single interventional radiologist. We retrospectively reviewed electronic medical records...
