This document is the third part of the guidelines for the interpretation and post-processing of cardiac magnetic resonance (CMR) studies. These consensus recommendations have been developed by a Consensus Committee of the Korean Society of Cardiovascular Imaging (KOSCI) to standardize the requirements for image interpretation and post-processing of CMR. This third part of the recommendations describes tissue characterization modules, including perfusion, late gadolinium enhancement, and T1- and T2 mapping. Additionally, this document provides guidance for visual and quantitative assessment, consisting of "What-to-See," "How-To," and common pitfalls for the analysis of each module. The Consensus Committee hopes that this document will contribute to the standardization of image interpretation and post-processing of CMR studies.

Pleural adhesions are a major challenge in standard and nonintubated video-assisted thoracic surgery. The currently available imaging techniques help to assess the presence and extent of pleural adhesions, but do not provide information on tissue deformability, which is crucial for intraoperative management. In this report, we describe the utilization of real-time elastography mapping of pleural adhesions. This technique enabled us to detect areas with softer adhesions, and helped establish the surgical plan in a difficult case of a patient scheduled for nonintubated video-assisted thoracic surgery.

Pulmonary hypertension (PH) is defined as resting mean pulmonary artery pressure ${\geq}25mmHg$ and is caused by multiple etiologies including heart, lung or other systemic diseases. Evaluation of right ventricular (RV) function in PH is very important to plan treatment and determine prognosis. However, quantification of volume and function of the RV remains difficult due to complicated RV geometry. A number of imaging tools has been utilized to diagnose PH and assess RV function. Each imaging technique including conventional echocardiography, three-dimensional echocardiography, strain echocardiography, computed tomography and cardiac magnetic resonance imaging has-advantages and limitations and can provide unique information. In this article, we provide a comprehensive review of the utility, advantages and shortcomings of the multimodality imaging used to evaluate patients with PH.

Pancreaticopleural fistula (PPF) is a rare complication in patients with pancreatitis. Its symptoms are similar to those of empyema or pleural effusion; therefore, it is important to consider PPF in the differential diagnosis. Herein, we describe the diagnosis and treatment of PPF in a patient presenting with unusual empyema and delayed hemoptysis.

본 연구의 목적은 적색 형광 단백질 유전자 형질 전환 복제견을 포함한 복제견들에서 측정된 심장 초음파 수치를 이전에 보고된 일반개의 정상 참고 범위와 비교하는 것이다. 일곱 마리의 복제견에서 M-mode, 2D-mode, pulsed wave Doppler 그리고 Tissue Doppler Imaging을 통해 좌심, 우심 그리고 우심실 우출로의 해부학적 특징과 심장 기능을 평가하였다. 모든 복제견들은 해부학적 구조에서 특이적인 이상을 나타내지 않았으며 측정된 수치들은 정상 참고 범위 이내에 있었다. 게다가 좌심과 우심의 심근 기능 모두 정상 참고 범위 이내에 위치하였다. 특히 복제 동물들에서 흔히 나타나는 우심 부전과 폐성 고혈압은 복제견들에서는 나타나지 않았다. 결론적으로, 성장이 끝난 복제견들에게서 는 출생시와 성장과정에서 심혈관계의 이상을 타나내는 징후는 확인되지 않았다. 그러므로 형질 전환 방법을 포함하는 체세포핵이식 기술은 복제견들의 심장 형태와 기능에 대해 심각한 부작용을 나타내지 않는다고 할 수 있다.

Herein, we report the case of a 60-year-old man, a smoker with a history of arterial hypertension and diabetes mellitus. After computed tomography (CT) for an episode of hemoptysis, the patient underwent elective thoracic endovascular aortic repair (TEVAR) because of a degenerative aneurysm of the descending thoracic aorta. The area of perianeurysmal pulmonary atelectasis reported on the CT scan was not considered. Three months later, he developed an aortopulmonary fistula without endoleaks. Although TEVAR is a relatively safe procedure, no detail should be overlooked in the preoperative evaluation in order to avoid life-threatening complications. Further, the effectiveness and modality of prolonged antibiotic prophylaxis and/or preoperative respiratory physiotherapy should be assessed in such cases.

Cerebral air embolism combined with cardiomyopathy secondary to pulmonary barotrauma is rare. Here, we report an unusual case of cerebral air embolism combined with transient cardiomyopathy secondary to large bulla rupture during a pulmonary function test after lung cancer surgery. The patient experienced loss of consciousness. Computed tomography and magnetic resonance imaging suggested a cerebral air embolism. Electrocardiography showed ST-segment elevation and abnormally high plasma levels of cardiac enzymes. Echocardiography and coronary angiography suggested cardiomyopathy. The patient was discharged with no sequelae.

We report the case of a 69-year-old woman who was diagnosed with intracardiac schwannoma without symptoms. Preoperative echocardiography and cardiac magnetic resonance imaging showed a mass attached to the interatrial septum. The initial diagnosis was a myxoma or a bronchogenic cyst. The tumor was successfully excised under cardiopulmonary bypass. However, the pathology of the excised tumor was consistent with schwannoma. We suggest that cardiovascular surgeons consider schwannoma to be a possible differential diagnosis for a mass close to the interatrial septum.
