High impact information on Fluoroscopy

• To determine the mechanism for the blood pressure increase, heart rate, blood pressure, and ventricular volumes (measured using fluoroscopy of tantalum midwall myocardial markers) were recorded before and after a 50% maximal voluntary contraction [9].
• Two weeks later, after recovery from thoracotomy, markers were visualized by biplane fluoroscopy, and video images were recorded during control conditions, after autonomic blockade, after inotropic stimulation with calcium, after methoxamine infusion (to increase afterload), and after blood volume augmentation (to increase preload) [10].

Chemical compound and disease context of Fluoroscopy

• Using a flow-guided, balloon-tipped microcatheter, we catheterize the fistula itself, verify balloon entry into the fistula with fluoroscopy and x-ray films, and then infuse the tissue adhesive isobutyl-2-cyanoacrylate with careful fluoroscopic control [11].

• Gadolinium-enhanced MR fluoroscopy images were obtained in 24 patients with 28 hepatic hemangiomas [15].

Biological context of Fluoroscopy

• Administration was terminated when either vasoconstriction was noted at fluoroscopy or when the maximal acetylcholine concentration was reached [16].
• The esophageal transit times of small- and medium-sized barium sulfate tablets were measured using x-ray fluoroscopy in 50 patients after swallowing while in both erect and supine positions with a 15-mL drink, and the esophageal transit times of large round and oval barium sulfate tablets were similarly measured in 25 patients [17].
• Radiation doses in interventional radiology procedures: the RAD-IR Study. Part III: Dosimetric performance of the interventional fluoroscopy units [18].
• Microfocus x-ray fluoroscopy also showed clear features of the bone and titanium implant The original drill hole and new bone formation could be recognized [19].

Anatomical context of Fluoroscopy

• Noninvasive diagnostic test choices for the evaluation of coronary artery disease in women: a multivariate comparison of cardiac fluoroscopy, exercise electrocardiography and exercise thallium myocardial perfusion scintigraphy [20].
• Pneumatic dilation of the lower esophageal sphincter was accomplished by endoscopic visualization and positioning of a modified polyurethane dilator (90 F diameter) without fluoroscopy in 17 consecutive patients with advanced symptomatic achalasia [21].
• With MR fluoroscopy, the flow of gadolinium-enhanced urine through the urethra was visualized in 19 patients, in 14 of whom with complete demonstration of the urethral anatomy subdivided into 5 segments [22].
• Patients were randomized into 2 groups; group 1 (n = 40) received corticosteroid (80 mg triamcinolone acetonide) and group 2 (n = 40) local anesthetic (1% mepivacaine), injected into the hip joint under fluoroscopy [23].
• Results of thoracic radiography and fluoroscopy of the esophagus, using a liquid suspension of barium sulfate, were suggestive of a vascular ring anomaly [24].

Associations of Fluoroscopy with chemical compounds

• Although it entails a radiation hazard risk, the use of fluoroscopy during caudal epidural steroid injection has increased to help place the medication more accurately and allowed physicians to maximize the procedure's therapeutic success rate [25].
• Metrizamide myelography in cervical spine trauma: a modified technique using lateral fluoroscopy [26].
• The absence of iron and flavin was also confirmed by atomic absorption, chemical analysis, and fluoroscopy, respectively [27].
• Percutaneous cervical cordotomy and subarachnoid phenol block using fluoroscopy in pain control of costopleural syndrome [28].
• Fluoroscopy was performed in four different positions: prone in alpha cradle, prone with an aquaplast mold, supine on a flat table, and supine with a false table under the buttocks [29].

Gene context of Fluoroscopy

• ROS formation was determined by DCF fluoroscopy and MMP-2 activity by zymography [30].
• Percutaneous vertebroplasty using polymethylmethacrylate was performed at three vertebral bodies (L2, L1, and T11) using careful techniques including venography, large cannula, proper preparation and amount of polymethylmethacrylate, and continuous visualization with fluoroscopy [31].
