“…[1][2][3] Myocardial tagging was first used in combination with low-dose dobutamine cardiovascular magnetic resonance (CMR) for the assessment of myocardial viability. 4,5 High-dose dobutamine-CMR (up to 40 g/kg per minute) has been useful for the detection of myocardial ischemia.…”

“…8 Reduction of myocardial circumferential shortening and systolic wall thickening are sensitive parameters for the detection of myocardial ischemia. 3,9 The addition of myocardial tagging to dobutamine-CMR may further enhance diagnostic accuracy. 1 Without tagging, ventricular contraction is evaluated by the movement of the endocardial and epicardial boundaries.…”

Background-The purpose of this study was to assess the value of high-dose dobutamine cardiovascular magnetic resonance (CMR) with myocardial tagging for the detection of wall motion abnormalities as a measure of myocardial ischemia in patients with known or suspected coronary artery disease. Methods and Results-Two hundred eleven consecutive patients with chest pain underwent dobutamine-CMR 4 days after antianginal medication was stopped. Dobutamine-CMR was performed at rest and during increasing doses of dobutamine. Cine-images were acquired during breath-hold with and without myocardial tagging at 3 short-axis levels.Regional wall motion was assessed in a 16-segment short-axis model. Patients with new wall motion abnormalities (NWMA) were examined by coronary angiography. Dobutamine-CMR was successfully performed in 194 patients. Dobutamine-CMR without tagging detected NWMA in 58 patients, whereas NWMA were detected in 68 patients with tagging (Pϭ0.002, McNemar). Coronary angiography showed coronary artery disease in 65 (96%) of these 68 patients. All but 3 of the 65 patients needed revascularization. In the 112 patients with a negative dobutamine-CMR study, without baseline wall motion abnormalities, the cardiovascular occurrence-free survival rate was 98.2% during the mean follow-up period of 17.3 months (range, 7 to 31). Conclusions-Dobutamine-CMR with myocardial tagging detected more NWMA compared with dobutamine-CMR without tagging and reliably separated patients with a normal life expectancy from those at increased risk of major adverse cardiac events.

“…3 RF tagging is used for the precise assessment of myocardial dynamics. 4 Other complementary CMR techniques use contrast agents (such as gadolinium) and MRI spectroscopy for evaluating myocardial metabolism. The ECG gating technique optimizes the spatial resolution for a better anatomical description during data acquisition and superposition during several cardiac cycles, and additional respiratory gating enables longer image acquisitions by monitoring the patients' breaths (diaphragm muscle movement or thorax movement).…”

Given the higher amount of detail it offers, the use of magnetic resonance (MR) in the field of cardiology has increased, thus leading to a decrease in the use of invasive and irradiating methods for diagnosing various cardiovascular disorders. The only precautions for MR imaging are metallic implants and advanced-stage chronic kidney disease. For the acquisition of clear and dynamic myocardial images, methods such as spin echo imaging for anatomical description, steady-state free precession imaging for the assessment of ventricular cavity size and function, flow velocity encoding for blood flow measurements, radiofrequency tagging for dynamics, and even spectroscopy for metabolism evaluation are used. Cardiac magnetic resonance (CMR) is considered the gold standard imaging method for the anatomical characterization of the heart and obtaining information related to myocardial dynamics. In case of ischemic events, CMR is used for a detailed description of the necrotic area and the complications, and for tracking the ventricular remodeling. By administrating a contrast agent (gadolinium), the difference between sub-endothelial and transmural infarctions can be distinguished, highlighting even microvascular lesions responsible for the extension of the necrosis. The assessment of the dynamics of ventricular remodeling and viability through late gadolinium enhancement (LGE) technology highlights the area of fibrosis and the occurrence of late complications.

“…77 Myocardial tagging allows the determination and quantification of LV wall thickening of specific myocardial segments. 78,79 Myocardial strain imaging provides a more accurate assessment of LV function, including circumferential and longitudinal contraction, compared with thickening analysis, which only shows cardiac motion in the radial direction. 80,81 Segmental strain analysis can be performed with CMR using myocardial tissue tagging with harmonic phase imaging, but has not yet become clinical routine.…”

Background:Patients with acute ST-elevation myocardial infarction (STEMI) benefit substantially from emergent coronary reperfusion. The principal mechanism is to open the occluded coronary artery to minimize myocardial injury. Thus the size of the area at risk is a critical determinant of the patient outcome, although other factors, such as reperfusion injury, have major impact on the final infarct size. Acute coronary occlusion almost immediately induces metabolic changes within the myocardium, which can be assessed with both the electrocardiogram (ECG) and cardiac magnetic resonance (CMR) imaging.Methods: The 12-lead ECG is the principal diagnostic method to detect and risk-stratify acute STEMI. However, to achieve a correct diagnosis, it is paramount to compare different ECG parameters with golden standards in imaging, such as CMR. In this review, we discuss aspects of ECG and CMR in the assessment of acute regional ischemic changes in the myocardium using the 17 segment model of the left ventricle presented by American Heart Association (AHA), and their relation to coronary artery anatomy.Results: Using the 17 segment model of AHA, the segments 12 and 16 remain controversial. There is an important overlap in myocardial blood supply at the antero-lateral region between LAD and LCx territories concerning these two segments.Conclusion: No all-encompassing correlation can be found between ECG and CMR findings in acute ischemia with respect to coronary anatomy.
