BACKGROUND Cryoablation is a treatment option for some patients with small exophytic lesions of the kidney. The purpose of this study is to determine the feasibility, safety, and intermediate-term treatment outcome of percutaneous cryoablation of renal cell carcinoma guided by horizontal open magnetic resonance imaging (MRI). METHODS We prospectively used(More)
Several MR parameters are sensitive to temperature change, notably, T1 relaxation time, proton phase shift (PPS) and diffusion coefficient. The PPS method has been considered for temperature monitoring during laser ablation owing to its tissue-independence and its ability to be used with a mid-magnetic field. Using the PPS method, we experimentally(More)
Fourteen patients with aortic dissection without intimal rupture were examined by means of magnetic resonance (MR) imaging, computed tomography (CT), or both. MR imaging showed a marginal high-intensity area along the aortic wall, while CT showed a nonopacified crescentic area along the aortic wall. These areas decreased in size within a short period and(More)
Volume data acquisition, three dimensional (3D) imaging, and multiplanar reformatting have become widely used for computed tomography (CT) and magnetic resonance imaging (MRI). As an extension of this technology, virtual endoscopic visualization of hollow organs has become a reality that is now finding its way into clinical CT practice. The same methods of(More)
Although local area networks (LANs) are commonplace in hospital-based radiology departments today, wireless LANs are still relatively unknown and untried. A linked wireless reporting system was developed to improve work throughput and efficiency. It allows radiologists, physicians, and technologists to review current radiology reports and images and(More)
OBJECTIVE Little information is available regarding the variations in pulmonary vein anatomy for the purpose of thoracic or video-assisted thoracoscopic surgery (VATS). To learn about the types and frequency of pulmonary vein variations for VATS, we reviewed a "tailor-made virtual lung" of patients that was constructed using three-dimensional multidetector(More)
PURPOSE Video-assisted thoracic surgery (VATS) has recently been adopted for complicated anatomical lung resections. During these thoracoscopic procedures, surgeons view the operative field on a two-dimensional (2-D) video monitor and cannot palpate the organ directly, thus frequently encountering anatomical difficulties. This study aimed to estimate the(More)
OBJECTIVE To determine the frequency distribution of bacteria on the external surface of eyes of patients with atopic dermatitis (AD) and to investigate the relationship between the frequency of bacterial colonization and the grade of atopy or ocular diseases associated with AD. DESIGN Comparative cross-sectional study. PARTICIPANTS Thirty-six AD(More)
The diagnostic potential of a new bone resorption marker, type I collagen-cross-linked N telopeptide (NTx), for bone metastasis of prostate cancer was evaluated. Ninty-one prostate cancer patients underwent bone scintigraphy, and urine NTx/creatinine (NTx/Cr) was measured. Urine NTx/Cr levels were compared with bone scintigraphic results. Urine NTx/Cr(More)
The performance of heat and moisture exchangers (HMEs) were clinically evaluated for the effectiveness of intraoperative heat conservation. Ten groups of patients were studied, nine groups with commercially available HMEs (Gibeck Humidvent 1, Terumo Brethaid, Portex Thermovent 600, NMI Pneumoist 2, Pall HME15-22, Gambro Engström Edith 1000, Gambro Engström(More)
