“…The tissue contrast is highly consistent, eliminating the variables in timing of the scan and contrast agent dose in contrast enhanced MRI. Thus, non‐contrast‐enhanced have been used for imaging of thoracic 36 and abdominal 20 large vessels. However, it has not been used to study the tumor invasive to the vessel walls.…”

BackgroundDue to their location and growth patterns, retroperitoneal tumors often involve the surrounding blood vessels. Clinical decisions on a proper treatment depend on the information on this condition. Evaluation of blood vessels using non‐contrast‐enhanced vessel wall MRI may provide noninvasive assessment of the extent of tumor invasion to assist clinical decision‐making.PurposeTo investigate the performance and potential of non‐contrast‐enhanced vessel wall MRI in evaluating the degree of vessel wall invasion of retroperitoneal tumors.Study TypeProspective.PopulationThirty‐seven participants (mean age: 60.59 ± 11.77 years, 59% male) with retroperitoneal tumors close to vessels based on their diagnostic computer tomography.Field Strength/Sequences3 T; vessel wall MRI sequences: two‐dimensional T2‐weighted MultiVane XD turbo spin‐echo (2D‐T2‐MVXD‐TSE) and three‐dimensional T1‐weighted motion sensitized driven equilibrium fat suppression turbo spin‐echo (3D‐T1‐MSDE‐TSE) sequences; conventional MRI sequences: T2‐weighted fat suppression turbo spin‐echo (T2‐FS‐TSE), T2‐weighted turbo spin‐echo (T2‐TSE), modified Dixon T1‐weighted fast field echo (T1‐mDixon‐FFE), and diffusion‐weighted echo planar imaging (DWI‐EPI) sequences.AssessmentAll patients underwent preoperative imaging using both non‐contrast conventional and vessel wall MRI sequences. Images obtained from conventional and vessel wall MRI sequences were evaluated independently by three junior radiologists (3 and 2 years of experience in reading MRI) and reviewed by one senior radiologist (25 years of experience in reading MRI) to assess the degree of vessel wall invasion. MRI were validated results from the clinical standard diagnosis based on surgical confirmation or histopathological reports. Interobserver agreement was determined based on the reports from three readers with similar years of experiences. Intraobserver variability was assessed based on categorizing and recategorizing the vessels of 37 patients 1 month apart.Statistical TestsIntra‐class correlation efficient (ICC), Chi‐square test, McNemar test, area under the receiver‐operating characteristic curve (AUC), Delong test, P < 0.05 was considered significant.ResultsThe accuracy of vessel wall MRI (91.96%, 95% CI: 85.43–95.71; 103 of 112) in detecting the degree of vessel wall invasion was significantly higher than that of conventional MRI (75%, 95% CI: 66.24–82.10; 84 of 112). The interobserver variability or reproducibility in categorization of the degree of vascular wall invasion was good in evaluating images from conventional and vessel wall MRI sequences (ICC = 0.821, 95% CI: 0.765–0.867 and ICC = 0.881, 95% CI: 0.842–0.913, respectively).Data ConclusionDiagnosis of vessel wall invasion of retroperitoneal tumors and assessment of its severity can be improved by using non‐contrast‐enhanced vessel wall MRI.Evidence Level1Technical EfficacyStage 3

Background: Careful preoperative planning in thoracic surgery is essential for positive outcomes especially in video assisted thoracic surgery (VATS) where palpation and 3-dimensional imaging is restricted. The objective of this study was to evaluate the ability of different imaging techniques such as Computerized Tomography (CT) scanning, maximal intensity projection (MIP) imaging, 3dimensional (3D) reconstruction as well as 3D printing, to define the anatomy of the hilar structures prior to anatomical lung resection. Methods: All patients undergoing elective lung resections by VATS for cancer under a single surgeon were identified over a three-month period. A single surgeon was asked to record the number of pulmonary artery branches supplying the lobe to be resected using the preoperative CT scan, MIP images and 3D reconstructed CT images. 3 patients had their lung hilum printed. These were then compared to the intraoperative findings. Results: 16 patients had their preoperative imaging analyzed. A further 3 patients had their lung hilum 3D printed. Although not statistically significant, the 3D prints of the hilum were found to be the most accurate measurement with a correlation of 0.92. CT, 3D reconstructed CT and MIP images tended to under recognize the number of arterial branches and therefore scored between 0.26 and 0.39 in terms of absolute agreement with the number of arteries found at operation. Conclusions: 3D printing in the planning of thoracic surgery may suggest a benefit over contemporary available imaging modalities and the use of 3D printing in practicing operations is being established.

Assessment of thoracic vasculature in patients with central bronchogenic carcinoma by unenhanced magnetic resonance angiography: comparison between 2D free-breathing TrueFISP, 2D breath-hold TrueFISP and 3D respiratory-triggered SPACE

Abstract: Both TrueFISP and SPACE allow satisfactory visualization of major mediastinal and hilar vessels and are comparable to MDCT in assessment of vessel invasion in patients with central lung cancer. TrueFISP sequences are better than SPACE in regard to image quality and VTR.
