Sarcoidosis, Cardiac
Systemic disease of unknown origin characterized by non-caseating granuloma.
Clinical involvement of heart by sarcoidosis is 5 %, but autoptic studies detect sarcoidosis in 20–50 % of patients.
MR: (1) Reduced LV function (global or regional); (2) patchy myocardial edema; (3) various patterns of late enhancement, early-stage epicardial/mid-wall involvement, late stage transmural; (4) RV can be involved.
Differential diagnosis: cardiomyopathies, myocarditis, myocardial infarction.
Saturation Band
MR: To reduce respiratory, pulsatility and flow artifacts put the saturation bands along phase encoding direction in LE, EG, and stress imaging.
Scimitar Syndrome
Abnormal connection of the right pulmonary vein to the IVC.
Anomalous systemic arterial supply to the right lower lung.
Right lung hypoplasia and sequestration.
Associated lesions: VSD, ASD, PDA, coarctation.
See also Pulmonary Venous Drainage Anomalies.
Senning Operation
Atrial switch operation in patient with TGA.
See also Transposition of Great Arteries.
Shimming
Correction of inhomogeneity of the magnetic field produced due to imperfections in the magnet or to the presence of external ferromagnetic objects.
If something wrong with the image, shim it!
Shunt
See ASD, VSD, PDA, PFO.
