Disease relevance of Magnetic Resonance Imaging, Cine

• CONCLUSIONS: Fast cine MRI with three-dimensional contrast-enhanced MRA provides rapid and comprehensive anatomic definition of APVs and ASDs in patients with adult congenital heart disease in a single examination [1].
• Velocity-encoded cine magnetic resonance imaging was used in 9 patients with moderate to severe aortic regurgitation (regurgitant fraction 49% +/- 17%) to measure regurgitant fraction, regurgitant volume, and forward stroke volume at baseline and 3 months after therapy with enalapril (mean dose 29 +/- 13 mg) [2].
• METHODS AND RESULTS: Twenty-five patients with an acute myocardial infarction underwent 99mTc-labeled tetrofosmin (99mTc-tetrofosmin) gated SPECT and cine magnetic resonance imaging (MRI) [3].
• The authors review the rapidly expanding recent literature that has now established cardiovascular MRI (including dobutamine cine MRI and vasodilator perfusion MRI techniques) as an ideal choice in the evaluation of myocardial ischemia and delayed contrast-enhanced MRI and low-dose dobutamine cine MRI for evaluation of viability [4].
• Cine magnetic resonance imaging of isolated right ventricular outflow obstruction in hypertrophic cardiomyopathy [5].

High impact information on Magnetic Resonance Imaging, Cine

• Findings were compared with those of coronary angiography, electrocardiography, cine MRI, and creatine kinase measurements [6].
• For all three groups, cine MRI was performed by combining coronal and axial gated spin echo and gradient echo cine sequences [7].
• METHODS AND RESULTS: Rest and low-dose (5, 10 microg dobutamine x min(-1) x kg(-1)) multiplane dobutamine-TEE and ultrafast cine-MRI studies were performed in 103 patients [8].
• A non-invasive cine magnetic resonance imaging (MRI) technique was developed to allow, for the first time, detection and characterization of chronic changes in myocardial tissue volume and the effects upon these of treatment by the angiotensin-converting enzyme (ACE) inhibitor captopril in streptozotocin (STZ)-diabetic male Wistar rats [9].
• Thirty-three mice of various age were studied under isoflurane anesthesia by electrocardiogram-triggered cine-MRI at 7 T. MRI revealed close correlations between RV and LV stroke volume and cardiac output (r = 0.97, P < 0.0001 each) [10].

Chemical compound and disease context of Magnetic Resonance Imaging, Cine

• The purpose of this study was to evaluate the comparative diagnostic values of dobutamine cine MRI and delayed contrast-enhanced MRI for predicting functional recovery of myocardial contraction in patients with acute reperfused myocardial infarction [11].

Biological context of Magnetic Resonance Imaging, Cine

• Left ventricular function was assessed by rest and dobutamine stress echocardiography as well as contrast-enhanced and cine magnetic resonance imaging scans [12].

Anatomical context of Magnetic Resonance Imaging, Cine

• Cine magnetic resonance imaging revealed a large accessory soleus muscle compressing the flexor hallucis longus in the tarsal tunnel of the affected extremity [13].
• Evaluation with cine magnetic resonance imaging demonstrated an anomalous pulmonary vein draining into the inferior vena cava below the diaphragm [14].
• All patients underwent steady-state cine MRI covering the entire left ventricle at rest and during low-dose dobutamine stress (10 micrograms/kg/min) [11].
• CONCLUSIONS: Selective closure of the dural defect based on cine-MRI will be useful for treating extradural arachnoid cysts [15].
• Net blood flow (bilateral internal carotid and vertebral arteries, and jugular veins) and cerebrospinal fluid (CSF) flow in subarachnoid space at the C2 level of cervical vertebra were measured using phase-contrast cine MRI [16].

Associations of Magnetic Resonance Imaging, Cine with chemical compounds

• Scimitar syndrome: cine magnetic resonance imaging demonstration of anomalous pulmonary venous drainage [14].
• OBJECTIVES: We sought to assess large bowel motility, induced by 2 prokinetic agents, senna tea and erythromycin, using functional cine magnetic resonance imaging (MRI) [17].
• Cine MRI and (31)P MRS were performed to monitor function and metabolism of the heart in the control (N = 10) and cariporide (N = 12) groups [18].
• Twenty-four patients with MI underwent stress, redistribution, and reinjection thallium SPECT imaging and cine MRI within several days [19].
• Assessment of left ventricular diastolic function in dilated cardiomyopathy with cine magnetic resonance imaging: effect of an angiotensin converting enzyme inhibitor, benazepril [20].

Gene context of Magnetic Resonance Imaging, Cine

• Consequently, we characterized left-ventricular (LV) morphology and function in vivo using high-resolution cine-magnetic resonance imaging (MRI) in 2- to 3-month old dystrophin-deficient (mdx) and MLP-null mice, and their respective controls [21].
• In 8 COPD patients without primary cardiac disease, RV wall thickness, mass, and end-diastolic volume were measured by cardiac-triggered cine MRI [22].
• Global and regional biventricular functions were analyzed in 14 patients diagnosed with arrhythmogenic right ventricular dysplasia/cardiomyopathy using cine magnetic resonance imaging and compared with similar data from 18 age-matched controls [23].
• In addition, cine-MRI depicted abnormal flow through the fenestration of the anomalous membrane (case 1 and 2) and shunted flow through the associated atrial septal defect (case 2) [24].
• This is mainly due to two points: The progress in the endoscopic instrumentation (namely the reduction in size of endoscopes and introduction of disposable models), and the establishment of Phase-Contrast Cine MRI as the gold standard method for the pre- and post-operative evaluation of the CSF dynamics [25].

Analytical, diagnostic and therapeutic context of Magnetic Resonance Imaging, Cine

• The aim of this study was to assess the feasibility of a stress test with dipyridamole (0. 56 mg/kg) to analyze myocardial perfusion by Gd first-pass enhancement in ultrafast gradient-recalled-echo MRI (perf-MRI), and wall motion by cine gradient-recalled-echo MRI (Cine-MRI) in one imaging session [26].
• CONCLUSION: Fast velocity-encoded cine MRI is a technique that shows promise in providing non-invasive detection of restenosis of coronary stent implantation [27].
• Proton imaging techniques include examination of pathologic alterations in MR relaxation times (T1 and T2), wall thickness and thickening, cine MRI combined with low-dose dobutamine, first-pass contrast enhancement patterns, and delayed contrast enhancement patterns [28].
• INTERPRETATION: Clinicians should be aware of spontaneous ventriculostomy demonstrable on cine MRI because it may obviate the need for a CSF diversion procedure [29].
• MRI and Cine MRI provided excellent anatomical and functional details of the heart and aorta in five patients with dissection of the aorta, aneurysm of the ascending aorta, suspected left ventricular apical thrombus, infiltrative cardiomyopathy and arrhythmogenic right ventricular dysplasia [30].
