BACKGROUND The results of studies identifying the risk factors for pneumothorax and bleeding in CT-guided coaxial lung needle biopsies were inconsistent and some were even contradictory. All reported series were small with patient populations averaging about 200. STUDY OBJECTIVES To determine the risk factors for pneumothorax and bleeding after CT-guided(More)
PURPOSE The role of positron emission tomography (PET) with fluorine-18-labeled fluoro-2-deoxy-d-glucose (FDG) in cervical cancer has not yet been well defined. We conducted a prospective study to investigate its efficacy in comparison with magnetic resonance imaging and/or computed tomography (MRI-CT). MATERIALS AND METHODS Patients with untreated(More)
PURPOSE To analyze variables affecting diagnostic accuracy of computed tomography (CT)-guided percutaneous coaxial cutting needle biopsy of lung lesions. MATERIALS AND METHODS A retrospective analysis of factors affecting diagnostic accuracy of CT-guided percutaneous coaxial cutting needle lung biopsy was performed in 631 consecutive procedures with(More)
Antral web is a rare cause of gastric-outlet obstruction. We report a case of gastric antral web with intermittent vomiting in a 10-year-old girl who received medical treatment for 6 months. The literature on this anomaly is reviewed with respect to differential diagnosis on the basis of upper gastrointestinal radiographic series, gastroscopy, and treatment(More)
BACKGROUND AND PURPOSE An accurate diagnosis of a parotid gland mass is essential for adequate management. We determined the clinical efficacy of USCNB in diagnosing parotid gland masses by using cutting needles of different bores. METHODS We reviewed records for 40 benign and 13 malignant parotid lesions. USCNB was performed by using 14-20-gauge needles(More)
PURPOSE The purpose of this prospective study was to evaluate the clinical usefulness of sonographically re-evaluating areas of microcalcification found mammographically before undertaking stereotactic core needle biopsy (SCNB). METHODS Patients with nonpalpable breast lesions appearing as microcalcifications on mammograms and who had been referred to us(More)
BACKGROUND/PURPOSE To review the complications, mortality rate and nutritional status of patients with head and neck cancer after fluoroscopically guided percutaneous gastrostomy (FPG). METHODS We retrospectively recruited 110 patients who had undergone FPG using 14-French balloon-retained catheters. The mortality rate, procedural and catheter-related(More)
BACKGROUND/AIMS To evaluate the usefulness of a combination of computed tomography and sonography for splenic abscess diagnosis and management determination. METHODOLOGY From January 1986 to June 1999, 30 patients of pyogenic splenic abscess were collected in our hospital. Computed tomograms of the spleen were performed on all of the patients, and(More)
Outpatient percutaneous liver biopsy is a common practice in the differential diagnosis and treatment of chronic liver disease. The major complication and mortality rate were about 2-4% and 0.01-0.33% respectively. Arterio-portal fistula as a complication of percutaneous liver biopsy was infrequently seen and normally asymptomatic. Hemobilia, which(More)
To correlate the dynamic computed tomography (CT) of hepatic focal nodular hyperplasia (FNH) with its size and pathology. The clinical data, pathological and dynamic CT findings of 36 FNHs in 24 males and 27 lesions in 22 females were reviewed. The pathological and CT findings of the 32 small FNHs (diameter < 3 cm) and 31 large FNHs (diameter ≥ 3 cm) were(More)
