Mediastinal invasion mri has constant limitations as ct

 Mediastinal invasion mri has constant limitations as ct
in numerousiating a tumor that abuts the mediastinal structures
from one invading the mediastinum. 108, 248 every ct and mri
depict mediastinal invasion by lung carcinoma with equal accuracy
ranging between 56% to 89% for ct and 50% to 93% for
mr. 102, 106–108, 230, 242, 249 the radiology diagnostic oncology
cluster ( rdog ) trials, showed slight superiority for mri in
diagnosing mediastinal invasion in a very terribly very little cluster of patients
as compared to ct, with areas beneath the roc for mri being
zero. 924 ( se zero. 034 ) versus zero. 832 ( se zero. 041 ) for ct. 106
involvement of the cardiac chambers, though rare, and
the pericardium is merely evaluated with mri. if the n ormal
2 to 3 mm thick curvilinear low–signal-intensity rim representing
the pericardium is disrupted, then tumor e xtension to
the pericardium is to be suspected, though this alone isn't
a contraindication to tumor resection. 250, 251 using cine mr
to see the sliding motion between the mass and adjacent
structures, cardiovascular invasion could be assessed, showing a
reported accuracy of 94%
