Permeability pulmonary edema was induced in ten rats by intravenous injection of oleic acid. Hydrostatic pulmonary edema was induced in another ten rats by continuous infusion of saline. Permeability pulmonary edema was detected as increased signal intensity in all animals on images obtained with repetition times (TR) of 2.0 sec and echo times (TE) of 28(More)
This study was performed to evaluate the effect of oral flora on [13C]urea breath test in detecting H. pylori infection and find an optimal method and timing for sample collection. Forty-five volunteers were included in this study. The [13C]urea breath test was performed using mouthwash, endoscopic administration, and conventional methods. According to the(More)
BACKGROUND Endoscopic 13C-urea breath test may avoid contamination of oral urease and rapidly discriminate Helicobacter pylori-positive and Helicobacter pylori-negative patients. AIMS To compare the accuracy of endoscopic 13C-urea breath test with conventional invasive methods in diagnosis of Helicobacter pylori infection. PATIENTS One hundred patients(More)
The diagnostic efficacy of time-activity curves (TAC) and common bile duct dynamics (CBDD) derived from quantitative cholescintigraphy (QC) was assessed in patients with suspected sphincter of Oddi dysfunction (SOD). Quantitative cholescintigraphy was performed on 34 cholecystectomized individuals with suspected SOD and 26 asymptomatic controls. Each(More)
As the mechanism of (99)mTc-MIBI scintimammography is different from that of anatomic modalities, the detection of breast cancer should not be affected by prior breast augmentation. The aim of this study was to compare the diagnostic accuracy of (99)mTc-MIBI scintimammography for breast cancer in patients with or without paraffinomas or siliconomas.(More)
Background: Direct radionuclide cystography (DRC) has the advantage of high sensitivity and low gonadal radiation exposure for the detection of vesicoureteral reflux (VUR), while renal cortical scintigraphy (RCS) is a highly sensitive and specific method for detecting renal cortical abnormality. The purpose of this study is to determine the incidence and(More)
BACKGROUND The role of eradication therapy is still controversial in H. pylori-related nonulcer dyspepsia (NUD). The aim of this study was to follow up the H. pylori status after eradication therapy in patients with NUD by using l3C-urea breath test (UBT). METHODS Patients with a clinical and endoscopic diagnosis of NUD were included. H. pylori infection(More)
BACKGROUND Non-ulcer dyspepsia (NUD) accounts for the majority of dyspeptic patients and studies on the epidemiology of Helicobacter pylori infection in NUD depend on a non-invasive and rapid diagnostic test. This study was performed to determine the sensitivity and specificity of a 15-min simplified protocol of the [13C]-urea breath test ([13C]-UBT) for(More)
UNLABELLED As a result of a high percentage of hypoactive upper poles of kidneys in traditional 99mTc-dimercaptosuccinic acid (DMSA) SPECT, a prospective study was conducted using 180 degrees acquisition technique compared with 360 degrees to minimize tissue attenuation. METHODS Anterior 180 degrees, posterior 180 degrees and 360 degrees renal SPECT(More)
