Background and purpose. Ultrasound has been used successfully to differentiate benign malignant breast lesions. The aim of this study was investigate the correlation between ultrasound prognostic indicators in cancer such as histological type, tumor grade, biological markers. Materials methods. findings (shape, margin, orientation, boundary, echo pattern, posterior acoustic feature, presence calcifications) 458 cancers were analyzed correlated with markers by univariate multivariate logistic...
Objective: To investigate the distinctive computed tomographic(CT) features of pyogenic liver abscess (PLA) caused by Klebsiella pneumoniae (KLA). Methods: 114 PLA patients (62 men, 52 women, age range 25-89 years, mean 60.9 years) with positive yield blood or pus cultures were divided into 2 groups; KLA group (n = 58) and non-KLA 56). We retrospectively reviewed CT images. The independent-sample t-test, X2 test, Fisher's exact test used SPSS for windows version 11.0. Results: Gas formation...
The objective of our study was to evaluate the incidence and spectrum renal complications extrarenal diseases syndromes in children with horseshoe kidney (HSK).The clinical data imaging studies 380 subjects (median age, 2.8 years) diagnosed HSK over a 24-year period were reviewed: 366 young adults 14 fetuses, one whom died utero. All documented. Patient initial modality, follow-up modalities, modality at diagnosis recorded.One hundred seventy-five patients (46.1%) had complications....
AIM:To evaluate the maximal-outer-diameter (MOD) and maximal-mural-thickness (MMT) of appendix in children with acute appendicitis to determine their optimal cut-off values diagnose appendicitis. METHODS:In total, 164 appendixes from 160 between 1 17 years old (84 males, 76 females; mean age, 7.38 years) were examined by high-resolution abdominal ultrasound for pain suspicion appendicitis.We measured MOD MMT at thickest point appendix.Patients categorized into two groups according medical...
Infectious diseases precede a significant proportion of acute ischemic strokes in children. Here, we report case stroke 3-year-old girl with Mycoplasma pneumonia-associated respiratory tract infection. She developed an acquired prothrombotic state protein S deficiency and had increased fibrinogen degradation product levels titer antinuclear antibodies. However, these conditions were completely alleviated at the 1-month follow-up examination. Infection M. pneumoniae may cause transient that...
Pectus excavatum, also known as funnel or sunken chest, consists of a depression the sternum so that ribs on each side protrude anteriorly more than itself.It is generally believed to be due genetically determined abnormality and portions diapgram. 1The vast majority patients are asymptomatic, except for anxiety in some their phy-sical deformity. 1Nevertheless, cardiac respiratory symptoms occasionally attributed this abnormality. 2hest surgeons convinced children with severe pectus...
The purpose of this study is to evaluate the feasibility thyroid shielding by measuring radiation dose, CT attenuation, and noise superficial neck structures during examination.We divided 84 patients without abnormalities seen on into two groups depending whether with a cotton spacer was applied over thyroid. On images, we measured attenuation noises in strap sternocleidomastoid (SCM) muscles. dose using head phantom containing ionization chambers located at 3, 6, 9, 12 o'clock...
Central compartment atopic disease (CCAD) has recently been suggested as a phenotype of chronic rhinosinusitis (CRS). This study aims to investigate the prevalence radiologic CCAD in CRS within pediatric population and identify its ability predict comorbid allergy asthma.Computed tomography endoscopic examination were conducted on patients with either or without nasal polyps. Allergen sensitization was determined multiple-allergen simultaneous test skin prick test. Serum total immunoglobulin...
Here we report the first case of a Korean infant with cloverleaf-shaped craniosynostosis, in which diagnosis Beare-Stevenson syndrome was suspected upon observation typical morphological features.This exhibited craniofacial anomalies, ocular proptosis, cutis gyrata, acanthosis nigricans, prominent umbilical stump, furrowed palms and soles, hypospadia, sacral skin tag coupled dermal sinus tract.Brain magnetic resonance imaging revealed that patient also had non-communicating hydrocephalus...
The risk of complications and discomfort in patients who undergo prolonged infusion a thrombolytic agent is significant when conventional catheter-directed thrombolysis used to treat lower extremity deep vein thrombosis (DVT).To evaluate the feasibility safety single-session endovascular treatment for symptomatic DVT.Single-session DVT was performed on 29 limbs 26 diagnosed with acute our institution. Nine were male 17 female, mean age 64 years (range 28-82 years). At 5-10 min after...

Purpose To compare intravoxel incoherent motion diffusion weight imaging IVIM-DWI MRI with DMSA for the evaluation of cortical defect in pediatric upper urinary tract infection (UTI) patients. Materials and Methods Forty-three kidneys 22 patients first episode febrile UTI were evaluated. DWI using IVIM model was performed eight b factors. The presence evaluated on apparent coefficient (ADC) map. used as standard reference. ADC, true (D), pseudo-diffusion (D*), perfusion fraction (F) both...
Owing to advances in critical care treatment, the overall survival rate of preterm infants born at a gestational age (GA) <32 weeks has consistently improved. However, incidence severe intraventricular hemorrhage (IVH) persisted, and there are few reports on in-hospital morbidity mortality. Therefore, aim present study was investigate trends surrounding mortality with IVH over 14-year period.This single-center retrospective included 620 GA weeks, admitted between January 2007 December 2020....
Objective To investigate the relationship between a chronic obstructive pulmonary disease (COPD) candidate gene, based on genomewide association study, and computed tomographic (CT) quantitative analysis; to find phenotype in COPD FAM13A gene. Materials Methods This study was conducted subclinical male smokers 2 groups with matched age smoking status; 162 subjects (mean age, 58 years) risk (CTGA, n = 85) reference (TCAG, 77) diplotypes replicated through underwent chest CT for analysis of...
Pulmonary tuberculosis (TB) can produce unusual radiographic findings. Further, negative sputum and bronchoscopic results are common. Early diagnosis is equally as significant treatment in the reduction of morbidity mortality associated with pulmonary TB.The aim this study was to assess computed tomography (CT) findings TB, confirmed via percutaneous transthoracic needle biopsy (PTNB), correlate these coexisting, underlying, lung diseases if present.Cross sectional study.We selected...
In the pubertal period, bone age advances rapidly in conjunction with growth spurts. Precise bone-age assessments this period are important, but results from hand and elbow can be different. We aimed to compare between around puberty onset elucidate chronological confirming according elbow-based age.A total of 211 peripubertal subjects (127 boys 84 girls) who underwent radiographs within 2 months was enrolled. Two radiologists a pediatric orthopedic surgeon assessed age. Hand graded using...
