To evaluate the effectiveness of simple percutaneous catheter drainage in treatment postoperative lymphocele.Percutaneous 23 symptomatic lymphoceles was performed with ultrasonographic (US) guidance 20 patients who had undergone radical pelvic lymphadenectomy because uterine malignancy. All were diagnosed on basis biochemical and cytologic findings aspirated fluid. The removed when amount daily less than 10 mL per day lymphocele seen at imaging to have resolved. Follow-up US 1, 3, 6 months...
<b>BACKGROUND AND PURPOSE:</b> Because of the high vascularization hemangiomas, preoperative misinterpretation may result in unexpected intraoperative hemorrhage and incomplete resection, which results persistence clinical symptoms or recurrence. Our purpose was to analyze various MR imaging features a spinal epidural hemangioma with histopathologic correlation. <b>MATERIALS METHODS:</b> After searching through pathology data bases 3 hospitals, we included 14 patients (9 male 5 female; mean...
Although left ventricular assist devices (LVAD) are increasingly used as a standard treatment for end-stage heart failure, few studies have explored LVAD-related readmissions. This study investigated the factors associated with readmission and nursing documentation in patients LVAD. A retrospective analysis was conducted on electronic medical records of who underwent LVAD implantation at tertiary hospital South Korea (January 2015-April 2023). Baseline clinical characteristics were analyzed...
A few neuroimaging studies have demonstrated the key brain areas associated with generalized anxiety disorder (GAD). However, metabolic changes in dorsolateral prefrontal cortex (DLPFC) of patients GAD are unclear. This study utilized 3-Tesla proton magnetic resonance spectroscopy ((1) H-MRS) to assess DLPFC change and its correlation symptom severity GAD.Patients diagnosed using DSM-IV-TR age-matched healthy controls participated this study. Brain metabolite concentrations were measured...
Objective: This study used functional magnetic resonance imaging (fMRI) to contrast the differential brain activation patterns in response visual stimulation with both male and female erotic nude pictures male-to-female (MTF) transsexuals who underwent a sex reassignment surgery.Materials Methods: A total of nine healthy MTF after surgery fMRI on 3.0 Tesla MR Scanner.The were induced by pictures. Results:The hormone levels postoperative normal range heterosexual females.The areas, which...
Functional magnetic resonance spectroscopy was used to compare brain metabolite changes between nonpostmenopausal and postmenopausal women exposed visual sexual stimulation with erotic video clips.Twenty 20 were enrolled in this study. Menopause defined as continuous amenorrhea for more than 12 months a follicle-stimulating hormone level higher 40 mIU/mL. Brain concentrations measured from localized voxel on the anterior cingulate gyrus, one of most important areas associated arousal....
We report the findings of a patient with an asymptomatic Arc Buhler (AOB) aneurysm, which was successfully treated by transcatheter coil embolization. An abdominal CT and angiography revealed intact pancreaticoduodenal artery arcade (PDAA) anomalous communication between SMA celiac axis, termed AOB. aneurysm observed at origin AOB embolization using coils. A follow-up imaging confirmed total occlusion patent PDAA. The successful results this treatment suggest that endovascular therapy axis...
Adrenal hemangiomas are rare tumor. Only 29 surgical cases have been reported. Although rare, adrenal should be included in the differential diagnosis of neoplasms. We report an additional case hemangioma that was removed surgically, and pertinent literature is reviewed.
Abstract The maximum likelihood method is a constrained iterative spectral deconvolution technique in which fitting model determined by minimizing the variance of fit time domain nonlinear manner. Application this to synthetic 2‐dimensional (2‐D) NMR spectra, have heavily overlapped multiplets associated with low signal noise ratios, yields contrast‐enhanced spectra simultaneous suppression and resolution improvement. This protocol greatly facilitates peak recognition often partitions...
The purpose of this study was to evaluate the usefulness in vivo 3T <TEX>$^1H$</TEX> MRS with short TE for prescreening various brain diseases. Together ten normal volunteers, 12 tumor patients(2 lymphomas, 5 malignant gliomas) and 5(benign meningiomas) 10 ischemic disease patients(6 acute 4 subacute infarctions) participated. Lymphomas showed increased intensities Cho Lac. Likewise, gliomas Lac, but decreased NAA <TEX>${\beta}\;{\gamma}$</TEX>-Glx; higher grade gliomas, Cho, mI Lip...
Abstract The maximum likelihood method (MLM) and related protocols were applied to the experimental 2‐D nuclear Overhauser effect (NOE) spectrum of a 24‐nucleotide RNA hairpin loop molecule. output becomes more valuable when diagonal symmeterization is followed by MLM. This symmeterized (SML) protocol restores original spectral information with high fidelity accurately partitioning components from overlapped peaks provides substantial improvements in line shape resolution, particular F 1...
Although the use of apodization functions in connection with postprocessing a 2D NMR spectrum proves improved spectral quality, there is usually trade-off between resolution enhancement and noise suppression due to classical "uncertainty principle." In this study, therefore, mathematical deconvolution technique called "Maximum Likelihood Deconvolution (MLD)" was adopted achieve sensitivity simultaneously. The MLD greatly facilitates visualization restoration genuine information from complex...
