OBJECTIVES To investigate the feasibility of 70 kV cerebral CT perfusion by comparing image quality and radiation exposure to 80 kV. METHODS Thirty patients with suspected cerebral ischemia who underwent dual-source CT perfusion were divided into group A (80 kV, 150 mAs) and group B (70 kV, 150 mAs). Quantitative comparisons were used for maximum(More)
PURPOSE To retrospectively demonstrate the specific CT findings of retroperitoneal neoplasms to diagnosis and differential diagnosis renal and non-renal tumors within the perirenal space in infants and children. MATERIALS AND METHODS We retrospectively reviewed the clinical data and CT images of 42 consecutive patients with surgically and pathologically(More)
PURPOSE To investigate whether and how spleen size measured on magnetic resonance imaging (MRI) could be used to stage liver fibrosis. MATERIALS AND METHODS Sixteen minipigs were used to prospectively model liver fibrosis staged by biopsy. Abdominal gadolinium-enhanced MRI was performed on the 0, 5th, 9th, 16th, and 21st weekend after beginning of the(More)
OBJECTIVE To determine the characteristics of Multi-detector Row CT (MDCT) image in distinguishing renal tumors from non-renal tumors within the perirenal space in infants and children. METHODS Data from 40 patients with surgically and pathologically proved retroperitoneal neoplasms within the perirenal space were collected. Based on the pathological(More)
BACKGROUND Nonrecurrent laryngeal nerve (NRLN) is a rare anatomic anomaly, which often co-occurs with aberrant right subclavian artery (ARSA). With this large case series, we present our experience of predicting the presence of NRLN by the means of chest X-ray film, thoracic computed tomography (CT), and ultrasonography. MATERIALS AND METHODS A(More)
The microwave has been widely used in the field of biology with the development of microwave technology. Previous studies suggest that suitable doses of microwave irradiation improved plant metabolism and enzymatic activities under cadmium stress and enhanced cadmium tolerance in wheat seedlings. The objective of this study was to test whether nitric oxide(More)
The aim of this study was to investigate how patterns of lymph nodes recurrence after radical surgery impact on survival of patients with pT1-3N0M0 thoracic esophageal squamous cell carcinoma. One hundred eighty consecutive patients with thoracic esophageal squamous cell carcinoma underwent radical surgery, and the tumors were staged as pT1-3N0M0 by(More)
OBJECTIVE To investigate features of crush extremity fractures associated with massive earthquake on digital radiography (DR) and multidetector computed tomography (MDCT). MATERIALS AND METHODS Six hundred and twenty-three consecutive patients with clinically confirmed crush extremity fractures arising from the 2008 Sichuan earthquake were enrolled into(More)
AIM To determine whether and how magnetic resonance imaging (MRI)-based total liver volume (TLV) and diffusion weighted imaging (DWI) could predict liver fibrosis. METHODS Sixteen experimental mature mini-pigs (6 males, 10 females), weighing between 20.0 and 24.0 kg were prospectively used to model liver fibrosis induced by intraperitoneal injection of(More)
OBJECTIVES To determine whether and how tumour size of resectable oesophageal squamous cell carcinoma (ESCC) measured with multidetector CT could predict regional lymph node metastasis (LNM) and N stage. METHODS Two hundred five patients with ESCC underwent radical oesophagectomy with three-field lymphadenectomy less than 3 weeks after contrast-enhanced(More)
