“…The pericardial sinuses and recesses are pericardial cavity dilations located along the lines of reflection between the visceral and the parietal pericardium around the venous pole of the heart and the aortopulmonary vascular pedicle. Many articles describe these structures [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. [4-7, 9, 10, 12] The highest point of the pericardium is the visceral-parietal reflection located at the level of the origin of the anonymous artery.…”

SUMMARYThe pericardial cavity, sinuses, and recesses are frequently depicted on Computed Tomography (CT) and Magnetic Resonance (MR).We here review the normal human pericardial structures as provided by MR imaging of young, healthy subject and CT scans acquired after iatrogenic coronary dissection. We compared such radiological information with cadaveric axial and sagittal sections of the human body provided by the Visible Human Server (VHS), Ecole Polytechnique Federale de Lousanne (EPFL), Switzerland.

“…Abnormal and doubt-ful structures should be evaluated for fluid content to exclude pericardial fluid in a recess. [3][4] For better delineating the target and normal structures computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET) were used together. It is also now possible to do 2D-2D match and 3D-3D match with the help of electronic portal imaging device (EPID) and cone beam CT (X-Ray volume imaging (XVI)) respectively to measure and account for interfraction variations.…”

The aim of this study was to evaluate the irradiated volume and doses to the target, heart, left lung, right lung and spinal cord, the number of segments and treatment time by using moderated deep inspiration breath hold (mDIBH) with active breathing control (ABC) and image-guided radiotherapy (IGRT) for patients treated with lung cancers. Methods: The suitability of this technique for lung patient treated with ABC was investigated and the solutions to achieve better treatments were discussed. Eleven lung cancer patients (3 left-sided and 8 right sided lesions) with stages I-III underwent standard free breath (FB) and ABC computed tomography (CT) scans in the treatment supine position. This can be achieved by applying respiratory manoeuvres, such as mDIBH, during which the threshold volume utilized is defined as 75-80% of the maximum aspiratory capacity. Five to seven, 6-MV photon beams with optimized gantry angles were designed according to the tumor location to conform to the PTV while sparing as much heart, spinal cord, and contra lateral lung as possible. For eleven patients, treatment planning using mDIBH CT data with intensity modulated radiation therapy (IMRT) was then reoptimized on the free breathing data set for comparison. The studied parameters of the plans for each patient were evaluated based on the average of the minimum, mean, and maximum difference in dose, the range of difference, and the p-value using two-tailed paired t test assuming equal variance. Results: The average volume of the planning target volume (PTV) in 11 patients increased to 1.32% in ABC compared to FB. The average volume of heart in 11 patients decreased to 2.9% in ABC compared to free breathing IMRT. In the case of lungs, the volume increased to 27.5% and 25.85% for left and right lungs, respectively. The range of mean difference in dose to the PTV in 11 patients was-54 cGy to 230 cGy with ABC technique when compared with free breathing. The range of mean dose difference of heart in 11 patients observed were-88 cGy to 66 cGy (p < 0.0410) between ABC and FB. The range of maximum dose difference to the spinal cord in 11 patients were-1592 cGy to 190 cGy (p < 0.041) with ABC technique when compared with FB IMRT. Monitor units (MUs) were-22.9% less in ABC compared to FB. Segments were more in ABC compared to FB for about 16.39% on an average. The average of minimum, mean and maximum difference in dose to the right lung and left lung were less in ABC compared with FB. Conclusion: In most of the cases, IGRT with ABC significantly reduces the mean dose to heart, right lung, left lung, and spinal cord compared with FB. Discrepancy observed in few cases made the statistical dat a inconsistent. Depending on anatomy and arbitrary phase of the breathing cycle, the results may vary and for better outcome of the results optimum treatment procedures need to follow.

“…7 Multidetector CT scanning has improved visualization of the pericardium and the pericardial recesses. 8 Pericardial disease may result in effusion and/or fibrosis of the pericardial membranes that can constrict the heart. Affected patients may present with exertional dyspnea, peripheral edema, 9 and chest pain; its severest manifestations include heart failure from pericardial tamponade 10 and constrictive pericarditis.…”

Evaluation of pericardial sinuses and recesses with 2-, 4-, 16-, and 64-row multidetector CT

Abstract: Visualisation rates of pericardial recesses are higher with 4-, 16- and 64-slice MDCT than with 2-slice MDCT. Therefore, radiologists need to be familiar with the different appearances of pericardial recesses on MDCT to avoid misdiagnosis.
