“…The other investigators also showed the 3D MR imaging technique to be useful for the clinical assessment of pulmonary veins or the relationship between the pulmonary vein and other anatomical structures such as tumor invasion to the pulmonary vein or left atrium. 9,10) The values of the pulmonary vein diameters obtained closely agreed with the findings of previous reports such as Chiba,et al 11) and Chen, et al 2,12) The upper pulmonary vein diameters on the left or right ranged from 16 to 20 mm. These values were almost identical to the findings in the present study.…”

SUMMARYPulmonary veins are the most frequent origin of focal and paroxysmal atrial fibrillation. Although radiofrequency ablation has been attempted for the treatment of focal and paroxysmal atrial fibrillation, the anatomy of the pulmonary vein is still not fully understood. To investigate the dimensions and anatomical variation of the pulmonary vein in patients with paroxysmal atrial fibrillation, we performed breath-hold gadolinium enhanced magnetic resonance (MR) angiography using a 1.5 T cardiac MR imager (GE CV/i) in 32 patients with paroxysmal atrial fibrillation (61 ± 8 years old), 11 patients with chronic atrial fibrillation (64 ± 9 years old), and 26 patients with normal sinus rhythm (55 ± 15 years old). Three dimensional images of the pulmonary veins were thus obtained, and the diameters of the most proximal portion of the left or right superior pulmonary vein and left or right inferior pulmonary vein were measured. Pulmonary vein branching variations were determined by a visual qualitative analysis by two separate readers' agreements, who were blinded to any clinical information. We focused on the existence of a complex-branching pattern draining into the orifice of four pulmonary veins. Patients with either paroxysmal atrial fibrillation or chronic atrial fibrillation showed larger superior pulmonary veins than those with normal sinus rhythm (mean ± SD; in the left superior pulmonary vein, 20 ± 3 mm, 23 ± 3 mm vs 16 ± 3 mm, P <0.05; in right superior pulmonary vein, 19 ± 4 mm, 19 ± 2 mm vs 16 ± 2 mm, P < 0.05). Complex-branching pattern was frequently observed in inferior pulmonary veins in patients with either paroxysmal atrial fibrillation or chronic atrial fibrillation; 25/32 patients with paroxysmal atrial fibrillation, 11/11 patients with chronic atrial fibrillation, compared to 7/26 patients with normal sinus rhythm. Complex-branching patterns were not observed in superior pulmonary veins in any patients in this cohort. Conclusion; In patients with paroxysmal atrial fibrillation or chronic atrial fibrillation, significant pulmonary vein dilation occurred mainly in the superior pulmonary veins, while a complex-branching pattern was frequently observed in the inferior pulmonary veins. These MR angiographic findings might be useful when From the

“…[7,8] It has been shown that coverage of bronchus or large vessels by tumor tissue is the most reliable finding of mediastinal spread. [6] Sensitivity should be ranged between 40 and 77% and specificity between 67 and 99% to evaluate mediastinal invasion by CT. [12,13] Aortic invasion is suggested, if the contact area between the tumor and aorta is greater than 90° or if there is obliteration of the triangular fat space between the esophagus, aorta, and spine adjacent to the primary tumor. [14,15] Thoracic CT scans are static, and are incapable of temporal and kinetic evaluation of the size differences, compression, and deletion of the fatty plane of the main moving structures such as esophagus and aorta.…”

ÖZAmaç: Bu çalışmada özofagus kanserinde konvansiyonel manyetik rezonans görüntüleme ve sine-manyetik rezonans görüntüleme ile invazyon varlığı açısından ortaya çıkan bulgular ameliyat sonuçları ile karşılaştırıldı.Ça lış ma pla nı: Bu prospektif çalışmaya Ocak 2012 -Şubat 2016 tarihleri arasında özofagusta tespit edilen kitlelerde invazyon varlığı ya da yokluğu açısından şüpheli toplam 37 olgu (21 erkek, 16 kadın; ort. yaş 63.3 yıl; dağılım 28-81 yıl) alındı. Tüm olgularda öncelikle konvansiyonel manyetik rezonans görüntüleme (T1-ağırlıklı, T2-ağırlıklı, short tau inversion recovery) ile lezyon özellikleri ve invazyon alanları araştırıldı. İnvazyonlu olgular, lezyonun dinamik özellikleri ve komşu dokular üç planda sine-manyetik rezonans görüntüleme alınarak tekrar değerlendirildi. Kitlenin komşu dokular ile olan bağıl hareketi, yağlı düzlemler ve invazyon durumu, boyut ve yapıya göre değerlendirildi. Bul gu lar:Olguların tümünde konvansiyonel manyetik rezonans görüntüleme ile invazyon varlığı saptandı. Otuz yedi olgudan 28'inde sine-manyetik rezonans görüntüleme ile invazyon saptanmaz iken, dokuz olguda tespit edildi. İnvazyon tespit edilmeyen 28 olgunun 20'si ameliyat edildi ve sonuçlar sine-manyetik rezonans görüntüleme bulguları ile uyumlu idi. Kalan sekiz olgu ise, ciddi komorbiditeler ve ameliyatı reddetme nedeni ile ameliyat edilemedi.So nuç: Kalp ve ana vasküler yapılar gibi hareketli dokulara yakın komşulukta olan özofagus kanserinde invazyonun doğru tespit edilmesinde sine-manyetik rezonans görüntüleme katkı sağlayabilir. Çalışma sonuçlarımıza göre, sine-manyetik rezonans görüntüleme, konvansiyonel manyetik rezonans görüntülemeden üstün görünmektedir.Anah tarsöz cük ler: Sine-manyetik rezonans görüntüleme; özofagus kanseri; invazyon. ABSTRACT Background:This study aims to compare the conventional magnetic resonance imaging and cine-magnetic resonance imaging findings with the operation results in terms of invasion existence in esophageal cancer.

“…Contrastenhanced MR angiography has been used for assessment of cardiovascular or mediastinal invasions (Takahashi et al 2000;Ohno et al 2001). Ohno et al (2001) described a series of 50 NSCLC patients with suspected mediastinal and hilar invasion of lung cancer visualized with contrast-enhanced CT scans, cardiac-gated MR imaging, and non-cardiac-and cardiac-gated contrast-enhanced MR angiographies (Fig.…”

Since the publication of the Radiologic Diagnostic Oncology Group Report (RDOG) in 1991, the clinical application of pulmonary magnetic resonance (MR) imaging to patients with lung cancer has been limited. MDCT has been much more widely available for staging of lung cancer in clinical situations. Traditionally, FDG-PET or PET/CT is the only modality that reveals biological glucose metabolism of lung cancer, and ventilation and/or perfusion scintigraphy is the only modality that demonstrates pulmonary function. However, recent advances of MR systems and utilization of contrast media make it possible to overcome the limitation of chest MR imaging. Therefore, in the last years, several investigators have demonstrated the significant comprehensive potential of MR imaging to substitute for MDCT and nuclear medicine examinations in lung cancer staging. Currently, MR imaging in lung cancer patients can be applied for (1) detection of pulmonary nodules, (2) characterization of solitary pulmonary nodules, and (3) assessment of TNM classification in routine clinical practice. We believe that further basic studies, as well as clinical applications of newer MR techniques, will play an important role in the future management of patients with lung cancer including MRI.
