“Purpose: To compare the imaging time and image quality obtained with whole-heart
coronary magnetic resonance (MR) angiography performed with five- and 32-channel coils in healthy subjects and determine the accuracy PND-1186 of MR angiography performed with 32-channel coils in the detection of obstructive coronary artery disease (CAD).
Materials and Methods: The institutional review board approved the study protocol, and all participants provided written informed consent. The authors studied 10 healthy subjects and 67 patients suspected of having CAD who were scheduled for coronary angiography. Unenhanced 1.5-T coronary MR angiography was performed with five-and 32-channel coils in healthy subjects and with 32-channel coils in patients. Clinically significant CAD was defined as a diameter reduction of at least 50% at coronary angiography. The sensitivity and specificity of coronary MR angiography were calculated.
Results: The mean imaging time was substantially reduced from 12.3 minutes +/- 4.2 (standard deviation) with five-channel coils to 6.3 minutes +/- 2.2 with www.selleckchem.com/products/blebbistatin.html 32-channel coils, with equivalent image quality scores.
Acquisition of MR angiograms was completed in all 67 patients, with a mean imaging time of 6.2 minutes +/- 2.8. The prevalence of CAD in the study population was 58% (39 of the 67 patients). The areas under the receiver operating characteristic curves as determined at vessel-and patient-based analyses were 0.91 and 0.90, respectively; the sensitivity and specificity at vessel-based analysis were 86% and 93%, respectively.
Conclusion: Whole-heart coronary MR angiography performed at 1.5 T with 32-channel coils permits noninvasive detection of CAD with substantially reduced imaging HKI-272 price time. This noninvasive approach can be an alternative to multidetector computed tomographic coronary angiography for ruling out obstructive CAD in patients who have a contraindication to contrast material and in young
subjects who are at higher risk from ionizing radiation. (C) RSNA, 2011″
“Hepatic hydrothorax is defined as a significant pleural effusion in patients with liver cirrhosis and without underlying cardiopulmonary diseases. Treatment of hepatic hydrothorax remains a challenge at present.
Herein we share our experiences in the treatment of 12 patients with hepatic hydrothorax by video-assisted thoracoscopic surgery (VATS). Repair of the diaphragmatic defects, or pleurodesis by focal pleurectomy, talc spray, mechanical abrasion, electro-cauterization or injection was administered intraoperatively, and tetracycline intrapleural injection was used postoperatively for patients with prolonged (> 7 d) high-output (> 300 ml/d) pleural effusion.
